gypsum crushing & processing-liming mining and rock technology

Gypsum is usually white, colorless transparent crystals, when impure ingredients can be dimmed, red, yellow or black. Hardness is 1.5-2. Specific gravity is 2.3. With flexibility and flexibility. Gypsum is a widely used industrial materials and building materials. Retarder for cement, gypsum building products, model making, medical food additives, sulfuric acid production, paper fillers, paint fillers.

According to the technical requirements, gypsum production line is usually divided into five parts, which are broken system, material storage and conveying system, grinding system, calcined system, and electric control system.

In the production and processing of gypsum, mainly using the following equipments: jaw crusher, bucket elevator, electromagnetic vibrating feeder, grinding mill machine, analysis machine, auxiliary equipment, fans, focus electronic control and other equipments. According to different needs of mill production line can be optionally configured with vertical mill machine, MTW European trapezium mill, high pressure roller mill, Raymond mill, super pressure trapezium mill, three ring medium speed micro powder mill, HGM micro powder mill and so on. Liming Heavy Industry designs dozens of specifications of gypsum production line, according to the different production processes tailored to the needs of different gypsum production lines.

1. Building materials: gypsum production line help upgrade the quality of plaster board. 2. Construction: gypsum production line for Cement Industry application. 3. Gypsum production line grand plans in the field of concrete. 4. Gypsum production line promote leapfrog development of mold industry.

Gypsum is widely used as industrial and construction material. Usually, the gypsum includes plaster stone and anhydrite. Plaster stone is also known as hydrated gypsum and soft gypsum. Its structure is compact mass and threadiness and the Mohs hardness of colorful plaster stone is 2. Anhydrites Mohs hardness is 3-3.5. Its density is 2.8-3.0g/cm3. The two kinds of gypsum is companied by each other and transformed under some geologic conditions. They can be used in cement retarder, gypsum building product, model, medical food additive, vitriol production, paper filler and paint filler, etc..

Passing through a hopper, raw gypsum materials are fed by vibrating feeder into the jaw crusher evenly and gradually for primary crushing. After first crushing, broken materials will be transferred by belt conveyor to impact crusher for secondary crushing. The crushed gypsum particles will then be transferred to vibrating screen for classifying. After classification, products in required size will be retained as final products, while the rest will be returned to the previous impact crusher for another crushing until getting all required sizes.

In the crushing and grinding of metallics for beneficiation, the sizing is normally done to liberate the metals or sulphides for further processing to improve recoveries of the basic metals or minerals. The objective is to reduce the ore in size through various closely controlled stages to that degree of fineness which gives an economic liberation of valuable mineral, but which avoids as much as possible the production of sliming fractions. A different philosophy applies to the crushing and grinding of Gypsum.

Gypsum as a mineral (CaSO42H2O) is number 2 on the Mohs scale of hardness; only Talc is softer. This would lead one to believe that it should be easy, to crush, like coal for example, and our equipment was formerly designed on this basis. Within the past 20 years, however, equipment suppliers guaranteeing their equipment performance have had to beef-up the design. Gypsum just didnt crush like a soft rock. Despite being soft, Gypsum is tough, a factor which is of critical importance when developing equipment specifications.

To prevent excessive delays at this point, proper crusher feed and feeder design is not enough. Close cooperation with the drilling and blasting must be maintained. One of the easiest places for cost reductions is by decreasing the powder usage. Since the emphasis is always on minimum cost per ton, this is looked at closely. However, large rock can cause excessive crusher delays. We have placed the primary crushing in the mining cost center in our accounting. This gives the Mining Superintendents both authority and responsibility to coordinate both activities.

The rock size in our quarries and mines depend on numerous factors. Method of transport (conveyor belts versus trucks), method of loading equipment (shovels, Joy mine type cars, front end loaders, etc.) all of which directly effect the rock sizing to the primary crusher.

In new installations., a single roll, toothed crusher of the heavy-duty type is recommended. The reservation to this is proper engineering of the feed to the crusher. That is, the size crusher feed opening with respect to the size rock anticipated. We have presently in use Jaw, Gyratory, Cone and Single or Double Roll crushers. All of these will work, with the usual criteria for final selection being the mining method (as it effects the size of rock fed to the primary crushing plant); tons per hour required; amount of headroom available for the installation; type of secondary crushing to be employed; and the lowest,capital investment consistent with these requirements.

The most commonly used unit is a Roller Mill with an integrated air separator, a very effective fine grinding machine, but requiring high capital investment. We still use Buhr Stones in few places (flat, circular granite stones operating like, a disc grinder) and Entoleters, Rod Mills and Tube Mills might also be used.
