Benefits of Vacuum Drying

There are many types of drying in industry and daily life. Some common drying methods are drum drying, vacuum drying, freeze drying, dielectric drying and supercritical drying.

Drying was widely applied in food industry, wood (as part of Timber processing), industrial field, chemistry, paper and washing powder. It plays an important role in our life.

Vacuum drying is ideal for drying materials which will be damaged or changed when exposed to high temperatures. The vacuum removes moisture while preventing the oxidation or explosions that can occur when certain materials combine with air. There are occasions when a solvent must be recovered or materials must be dried to very low levels of moisture, and this is suitable for us to use vacuum drying.

A vacuum dryer is typically used for separating a volatile liquid by vaporization from a powder, cake, slurry, or other moist material. This process is fundamentally thermal and doesn’t involve mechanically separating the liquid from the material, such as in filtration or centrifugation.

Dryer, usually can be divided into two categories: direct-heat dryer and indirect-heat dryer. Unlike a direct-heat dryer, in which the material is immersed directly into the heating media (usually a hot gas stream) and is dried by convection, a vacuum dryer is an indirect-heat dryer. For vacuum drying, the heat is transferred to the material as it contacts the dryer’s heated surface, drying the material by conduction. It is crucial for us to understanding this distinction and grasp the advantages and limitations of vacuum drying. It is also of great importance for us to select a vacuum dryer which will help us efficiently and economically achieves  process goals.

Vacuum drying is especially effective for heat sensitive materials and allows for closed system benefits where solvant recovery is required. SBM has custom-designed vacuum drying solutions for our clients. Complete systems can be produced with a variety of options tailored to your process.

Custom-designed drying system can include:

Antimony ore introduction

Antimony is a silvery-gray, brittle semi-metal with atomic number 51. It rarely occurs in nature as a native element, but is found in a number of different minerals, the most important of which is stibnite (SbS3). Antimony is often called a semi-metal, because in pure form it is not shiny and malleable like true metals.

Antimony is not an element which most people see daily in a recognizable form. However, it is present in many products in everyday use. Antimony’s moderate price allows it to be used in a wide variety of applications.

significant application of antimony ore

The most important use of antimony in the United States is in chemicals used to impregnate plastics, textiles, rubber, and other materials as a flame retardant – that is, a form of fireproofing. This is required by federal law for certain childrens’ clothing. Over half the annual U.S. antimony consumption is for the manufacture of flame retardants.

Antimony is also used for pigments in plastics, paints, rubber, and for a wide variety of minor uses, including medicines, fireworks, and others. Antimony oxide is a brilliant yellow color, accounting for much of the pigment use.

A tiny amount of highly purified antimony metal is used in the computer industry to make semiconductors. To be useful in this application, antimony has to be 99.999% pure!

antimony ore crushing process

in antimony ore crushing and grinding process, the most commonly used crushers and grinding mills are jaw crusher, cone crusher, hammer crusher and ball mill, ultrafine grinding mill, etc. It is usually a complete production line for antimony ore crushing.

antimony ore beneficiation begins with the communition of extracted ore in preparation for further activities to achieve ore values. Crushing operations are designed to produce uniform size particles by crushing, grinding,and wet or dry classification. The capital investment and operation costs of milling equipment are high. For this reason, it is important for us to choose the suitable crushing equipment.   Factors that decide the choosing of crushing machine include the value concentration of the ore, its mineralogy, hardness, and moisture content.

Crushing is a multistaged process and may use dry or wet ore feed. Typically, primary crushing take place at the mine site. Primary crushing is accomplished by using jaw crusher or cone crushers. Primary crushing yields chunks of ore ranging in size from 6 to 10 inches.Oversize material is passed through additional crushers and classifiers to achieve the desired particle size. The ore is then crushed and sized at a secondary milling facility.

Jaw crusher for antimony ore: Jaw crusher is used in primary crushing station. It can crush antimony ore into smaller sizes. Thus, these small antimony ore can be fed into mill such as ball mill for grinding.

impact crusher is generally used after jaw crusher, and can crush hard stones, not only the antimony ore, but also other ores such as copper, bauxite, gold, Kaolinite, manganese etc.

Secondary milling (comminution) further reduces particle size and prepares the ore for beneficiation processes that require finely ground ore feed. The product resulting from this additional crushing is usually less than 1 inch (1/2 to 3/4 inches). Secondary crushing, if necessary and economical, is accomplished by using standard cone crushers or impact crusher.

Cone crusher is the most common fine crusher, and usually used as final crushing machine. It has four types: spring cone crusher, CS cone crusher, hydraulic cone crusher, hcs90 cone crusher. Each cone crusher has their different applications.

Subsequent fine grinding further reduces the ore particles to the consistency of fine powder (325 mesh,0.0017 inches, 0.44 microns). The choice of grinding circuit is based on the density and hardness of the ore to be ground. The benefit of autogenous grinding is that it is less labor- and capital-intensive.

crushing equipment recommended

Ball mill was used as antimony ore grinding mill. In antimony ore concentrator, it was used to grind antimony ore into fine powder.

Vibrating feeder and screening machine used in antimony ore mining

Vibrating feeder is used to feed antimony ore evenly to antimony ore crushing and grinding machine.

vibrating screen is the screening machine. It screens out the appropriate antimony ore particles, these particles enter into ball mill for grinding.

In order to make the size of antimony ore materials as fine as possible before entering into milling machine, the crusher must have an excellent fine crushing capability to reduce antimony ore size. To achieve this crushing effect, two grades of jaw crushers and one fine crusher (high thin breaker machine) are applied in the crushing process. Two types of jaw crushers are coarse and fine jaw crushers. Tertiary fine crushing machine is the key of the whole production line.

silver ore introduction

Silver has a bright, metallic luster, and when untarnished, has a white color. Silver can alloyed with a number of different elements to form a variety of minerals and ores. It is also found in very small amounts in gold, lead, zinc, and copper ores. A full two-thirds of the silver resources in the world are found in association with these other metal ores. The remaining third is found in association with deposits of gold. The most important ore mineral of silver is argentite (Ag2S, silver sulfide)

The application of silver

Silver has been used as jewelry and decorative items for thousands of years. Likewise, it has been used for silverwar. It is also used in electrical products because it conducts electricity so well (silver actually conducts electricity more efficiently than copper). It is used by dentists in amalgam fillings. Silver is also used in the production of bearings.

Brief introduction about copper ore

Copper ore is  a mineral that can be found in large deposits and relatively close to surface.

As a mineral, natural copper (also called native copper) is relatively rare. Most copper in nature is found in minerals associated with sulfur, or in the oxidized products of these minerals.

Significant application of copper ore

Copper was used in electric cables and wires, switches, plumbing, heating, roofing and building construction, chemical and pharmaceutical machinery, alloys (brass, bronze, and a new alloy with 3% beryllium that is particularly vibration resistant), alloy castings, electroplated protective coatings and undercoats for nickel, chromium, zinc, etc., and cooking utensils. The leading producer is Chile, followed by the U.S., and Indonesia.

Modern culture and life is heavily dependent on copper and copper products. It is a metal that has the desirable physical properties of being malleable and ductile. Malleable means it can be hammered and molded into shapes; ductile means it can be drawn into wire. As a result, copper pipes are used to bring water to and through our buildings.  It has been said that the amount of copper a society consumes is a direct indicator of the advancement of that society. In other words, those societies that consume larger amounts of copper are considered more technologically developed.

copper ore beneficiation process

copper ore beneficiation process can be divided into the following steps:

The first step of copper ore beneficiation is crushing. Crushing is often divided into three stages, namely, primary crushing, secondary crushing and fine crushing. To complete primary crushing, people usually use a jaw crusher or impact crusher. They can crush copper ore into smaller sizes. Thus, these smaller copper ore can be fed into mill such as ball mill for grinding. Impact crusher is generally used after jaw crusher, and can crush hard stones, not only the copper ore, but also other ores such as copper, bauxite, tin, Kaolinite, manganese etc.

Secondary crushing: after reaching certain size, the materials can be fed to grinding mills for further grinding. Commonly used grinding mills are ball mill, vertical roller mill, high pressure suspension grinding mill, MTM medium speed trapezium mill and SCM series super thin mill.

After grinding by a ball mill, the copper ore fines are fed into spiral classifier. By the principle of different solid particles have different sedimentation rate in liquid, spiral classifier washing the mixture of ore and grading them.

After washing and grading, mineral mixture were fed into the magnetic separation. Due to the different susceptibility of various minerals, magnetic and mechanical force can separate the magnetic material from the mixture materials.

Flotation separation: The process used to separate copper and metal sulfides from the gangue. Aeration of the milled slurry, and the addition of specific chemical reagents, encourages froth formation, while activators are added to promote flotation of copper-bearing compounds. The froth that floats to the surface contains most of the copper and copper sulfides, and is extracted for further treatment. This material is known as the concentrate. After magnetic separating, minerals particles were sent to the flotation separation. Now, put into different chemicals according to mineral characteristics, so you can make the minerals and other substances to be separated.

After the minerals being separated, they were taken into thickener for initial concentrating. Thickening reduces the water content of the concentrate slurry, separating the water from the heavier mineral-rich solids through gravity. Then, after drying, you can get dry materials.

Beneficiation equipment recommended

For primary copper ore crushing, you can choose SBM Jaw Crusher. SBM has been engaged in researching and manufacturing jaw crusher for almost 30 years. There are perfect after-sale services including free training and maintenance.

PE series jaw crusher: mainly used for medium-grained crushing of a variety of ores and bulk materials, whose compression strength not more than 320 Mpa, and it can be divided into coarse broken and fine broken.

Compared with primary crushing, you should pay more attention to the size controlling and shaping in secondary crushing. You can choose SBM Cone Crusher for secondary crushing.

Vibrating screen: It is features of reliable structure, high screening efficiency, low noise, durability, easy maintenance, use of safety. It is widely used in product classification of mining industry, building materials industry and so on.

Vibrating feeder: It can feed materials into crushing machine continuously and evenly in the production process, and then crude screen materials.

It is used for making buildings, roads, bridges, vessels pipes etc etc etc. As the cement formulations develop cement is increasing its range of applications such that it is making inroads into those presently monopolised by metals. In the cement crushing process, it is important for us to choose the suitable crushing equipment. The

common used crushing machine for cement are crusher and grinding mill.

In the crushing plant, cement was crushed into fine powder. The whole process is as follows: First, cement enter into jaw crusher for primary crushing, then into impact crusher for secondary crushing, finally, the cement enter into the cone crusher for fine crushing, then through screening machine, the suitable cement is screened out, while the unsuitable cement return to the crushing plant for re-crushing. Through a series of crushers, the rock is reduced to a size less than 100 mm and stored until required. Mobile cement crusher is the very convenient mobile crushing machine in cement making and waste debrics recycling.

brief introduction about iron ore

Iron (Fe) is a metallic element and composes about 5% of the Earth’s crust. When pure it is a dark, silvery-gray metal. It is a very reactive element and oxidizes (rusts) very easily. The reds, oranges and yellows seen in some soils and on rocks are probably iron oxides.

The principle ores of iron are Hematite, (70% iron) and Magnetite, (72 % iron). Taconite is a low-grade iron ore, containing up to 30% Magnetite and Hematite.

Significant application of iron ore

In the United States, almost all of the iron ore that is mined is used for making steel. The same is true throughout the world. Raw iron by itself is not as strong and hard as required for construction and other purposes. So, the raw iron is alloyed with a variety of elements (such as tungsten, manganese, nickel, vanadium, chromium) to strengthen and harden it, making useful steel for construction, automobiles, and other forms of transportation such as trucks, trains and train tracks.

brief introduction about aluminum ore

Aluminum is the most abundant metal element in the Earth’s crust.  The main source of aluminum is Bauxite .

Aluminum is a silver-white metal, very light in weight,  yet relatively strong. In addition, aluminum is ductile, that is to say, it can be drawn into wires or pressed into sheets or foil. It is the most abundant metallic element, and the third most abundant of all elements in the Earth’s crust, making up 8% of the crust by weight. Only silicon and oxygen are more plentiful.

Significant application of aluminum ore

Aluminum has numerous applications in the home and industry, and is a familiar metal to nearly everyone. Aluminum is used in the United States in packaging, transportation, and building. Guinea and Australia have about one-half of the world’s reserves. Other countries with major  reserves  include Brazil, Jamaica, and India.

Marble is a metamorphic rock composed of recrystallized carbonate minerals,most commonly calcite or dolomite.Marble is commonly used for sculpture and as a building material.

Application of Marble

Sculpture- White marble has been prized for its use in  sculpture since classical times. This preference has to do with its softness, relative isotropy and homogeneity, and a relative resistance to shattering. Also, the low index of refraction of calcite allows light to penetrate several millimeters into the stone before being scattered out, resulting in the characteristic waxy look which gives “life” to marble sculptures of the human body.

Construction- Construction marble is a stone which is composed of calcite, dolomite or serpentine which is capable of taking a polish.TheTaj Mahal is entirely clad in marble. It is really a miracle.

jaw crushers are mainly used as primary crushers. Their main purpose is to produce material that can be transported by belt conveyors to the next crushing stages. The crushing takes place between a fixed and moving jaw which is mounted on a pitman, and its motion it set up by the movement produced by the eccentric shaft at the top of the pitman.

After primary crushing, the materials were fed to a ball mill for secondary crushing.

After grinding by a ball mill, the marble fines are fed into spiral classifier. By the principle of different solid particles have different sedimentation rate in liquid, spiral classifier washing the mixture of ore and grading them.

After washing and grading, mineral mixture were fed into the magnetic separation. Due to the different susceptibility of various minerals , magnetic and mechanical force can separate the magnetic material from the mixture materials.
