The size of the dewatering screen has a great impact on the efficiency of the equipment. Generally, manufacturers have a set of solutions to meet the needs of different customers. There are many shapes of sieve holes in dewatering sieves, common ones are round, square and rectangular. Compared with sieve holes of other shapes, round sieve holes can pass through the sieve holes with the same nominal size. The particle size of the product under sieve is smaller. The particle size of the particles that actually pass through the round sieve holes is only the average size of the particles passing through the square sieve holes of the same size. The effective area of ​​the sieve surface of the rectangular sieve is larger. The production capacity is higher. When dealing with materials with more water, it can reduce the clogging of the sieve surface. . Therefore, when it is required that there is no fine powder in the sieve, strip and flake particles are allowed in the sieve, the material is ...

Rod mill grinding quartz sand has the characteristics of uniform strength, high efficiency and high sand purity. The use of crusher and rod mill together can efficiently produce quartz sand and machine-made sand. 1. The discharge particle size is controllable One of the reasons for choosing a rod mill instead of a ball mill for grinding quartz sand is the particle size of the finished product. For quartz sand grinding, the output particle size is usually between 40 meshes and 120 meshes, so it can be said that the particle size is not very fine. Therefore, we have to choose a rod mill, because the rod mill for grinding quartz sand is in surface contact with the material. 2. Grinding also has a scrubbing function In the purification process of quartz sand, a very important step is scrubbing, to wash off the impurities on the surface of quartz sand, and then select and purify. The use of a rod mill grinding quartz sand to process quartz sand can also play a role in scrubbing to a certai...
