How to adjust the fineness of basalt sand making

1. Increase the rotor speed of the vertical shaft impact sand making machine, increase the linear speed of the aggregate in the crushing cavity (this system is 65m/s), increase the sand formation rate and the stone powder content of the crushed sand, and at the same time reduce the fineness of the sand. number.

2. Adjusting the feed gradation of the vertical shaft impact crusher can greatly improve the sand making effect.

3. The <5mm aggregate produced by the production line system after coarse crushing and medium and fine crushing has a high stone chip content. The process prevents this part of the aggregate from producing finished materials, and allows all the <5mm aggregates after medium and fine crushing to enter the vertical shaft impact crusher for shaping. To control the quality of finished sand.

Several types of flocculation tanks

The concentrator is a continuous working concentration and clarification equipment. It is mainly used for dehydration of fine and tailings pulp in wet beneficiation operations. It is also widely used in the concentration of solid slurry in coal, steel, chemical, building materials, water sources and sewage treatment. And purification. The ordinary concentrator works reliably, has low operating costs, and can store and buffer the feedstock. However, it is based on the gravity sedimentation of the particles. The sedimentation velocity is proportional to the square of the particle diameter, which is used to treat the microparticles and has low efficiency. The high-efficiency concentrating machine mainly uses the reasonable use of flocculant and the cloth feeding method at the bottom to increase the sedimentation speed, which is one of the most important progress in the concentration technology. Different type of flocculation tanks Thickener tanks , Deep Cone Thickener, Sludge Thi...

How to desilting municipal drains and canals?

The river channel sludge filter press is a special equipment, which is used to deal with river channel dredging sludge, lake sludge and sludge brought ashore by cutter suction boats. The equipment adopts the principle of automatic water removal and extrusion dehydration. First, the sludge is introduced into the equipment through a slurry pump, and after pressing and squeezing, the output is clear water and mud cake. This treatment method does not require manual unloading, and the moisture in the mud cake is effectively removed, which can be directly packaged and transported, and the clean water produced can be directly discharged. Automatic processing: The equipment adopts an automatic control system to realize automatic water removal and extrusion dehydration without manual operation, which greatly saves labor costs and time.
