    1. Jaw Crusher
    2. Jaw CrusherThe jaw crusher is commonplace on rock crushing job sites. Usually used to handle coarse materials, the crusher allows large-size particles to be crushed, delivering high processing capacity. Crushing jaws are cheap but sturdy, which means little money to be spent on replacement.
      Integration of jaw crusher, cone crusher, impact crusher, hammer mill, double roller crusher, vibrating feeder, and vibrating screen turns the crushing into a semi-automatic process. Typically, crushing stages are often followed by milling stages, if the material needs to be processed into finer particles in a grinder. The grinding operation is usually performed by a ball mill.
    1. Impact Crusher
    2. Impact CrusherOutstanding functionality and exceptional performance partly explains why our impact crusher is so widely applied in the hydraulic engineering and residential building construction industries. Further benefits of this crusher include small footprint, simple structure, great size reduction ratio, little energy consumption, high crushing capacity, and maximum size uniformity of finished products. As one of the most promising equipment, the crusher is able to selectively crush aggregates below a given size.
    1. Sand Making Machine
    2. Sand Making MachineThe sand making machine is essentially a vertical shaft impactor, which functions to break down gravels, cobble stones, and other large-size rocks. The resulting product can be used in highway construction and building industries. Depending on customer specific requirement, the machine can be reconditioned to produce the exact size of output product. Users can pair this machine with jaw crusher, cone crusher, vibrating screen, and sand washer to form an integrated sand making line.
    1. Screw Classifier
    2. Screw ClassifierBasic concept behind the classifier for gravity is that particles with different densities have different velocities of motion in water under the influence of gravity. Finer particles tend to flow on the surface while coarse ores sink to the bottom. As a result, finer powders naturally overflow the trough of the classifier. After that, the bottom ores are pulled to the surface by the rotating screw and discharged from the tough, too.
    1. Log Washer
    2. Log WasherWell known for its ability to remove clay and other impurities from the stone surface, the log washer has become a staple in rock crushing, ore dressing, and building material processing industries. Depending on the size of stones, crushed gravels, or ore feeds to be processed, different models can be selected to suit your applications. Custom design is also available upon your request.
    1. Ball Mill
    2. Ball Mill The ball mill is a key device for grinding crushed materials. It is widely used in the production line for powders such as cement, silicates, building materials, refractory material, fertilizer, and glass ceramics as well as for ore dressing of both ferrous and non-ferrous metals.
      The ball mill is commonplace in the ore dressing plant and cement factory. It serves to pulverize literally any granulated materials. Often used in conjunction with crushing equipment, the device provides users with large handling capacity, ease of operation, and maximum stability.

      Various ores and other materials, either wet or dry, can be ground by this grinding machine. Depending on the ways of discharging materials, this grinder can take two forms: grate type and overfall type.

    1. Rotary Drum Dryer
    2. Rotary Drum DryerThe drum sits at a low angle from the level ground. When the material flows from a higher end downward to the drum, it is met by another flow of heating medium that enters from the bottom of the drum. Hence, a counter-current is formed to allow a maximum contact area between the heating medium and heat material. Granted, the flow of feed stock can be in the same direction as that of heating medium.
    1. Rotary Kiln
    2. Rotary KilnAs the kiln rotates, the refractory bricks and heat exchanger roll along with it at a low speed. The kiln is often inclined slightly from the level ground. The process material is fed into the upper end of the cylinder. During its moving downward the cylinder, the material is met by an opposite flow of hot air. There is a burner set at the lower end of the kiln cylinder, from where flame is ejected into the cylinder. The off-gas is discharged from the upper end of the cylinder. During the whole process, the material undergoes both chemical and physical changes. Finished products are discharged from the lower end.
    1. Coal Gasifier
    2. Coal GasifierIn a gasification reactor, air and water vapor are added causing chemical reaction with coals to produce syngas, which is primarily comprised of hydrogen and carbon monoxide. The reactor can accommodate a variety of feed stocks, including char coal and coke. The resulting gas is utilized for heating furnaces in machinery, metallurgy, chemical glass, building material, food, and textile industries.
  • Envrionmental Protection
  • A central lighting and heating system is adopted to provide light, and warmth or coolness from one point to multiple rooms. The purpose of centralized control is to minimize the use of electricity as well as other energy forms. Wastes produced by workers should be sorted out, in order for a clean working environment ...
