In practical processing process, the coarse ore is first crushed by   jaw crusher   until to a suitable particle. And then, the ore is conveyed by hoister and feeder into the ball mill for further crushing. After grinding of ball mill, the qualified ore will be classified. Because of different specific gravity, the solid particle has different settling velocity in the liquid, and it is washed and classified. And then, the ore put into the  magnetic separator . Ore varies from specific susceptibility, and it gets different magnetic force and gravity. This process contributes to separating the magnetic material and non-magnetic material. After that, the material is conveyed into the flotation cell. According to their different physical and chemical properties, the objective mineral and other minerals are separated by flotation reagents. When the objective minerals are achieved, they contain much moisture. The dry iron concentrate is achieved by the thickening and drying....

China is a major nation of mining production and consumption in the world. Many provinces and cities possess high-quality   lead-zinc mine   in China, however, due to the unreasonable utilization, the large number of lead-zinc tailings are piled up for a long time, which takes up a lot of lands. Besides, a large amount of heavy metals results in severe soil and river pollution through releasing and migration.

It is unavoidable for   crusher   to occur blockage in crushing production line, which not only reduces the crushing capacity, influence of finial granularity, but also affects the production efficiency, even cause equipment damage. So, how to prevent and solve the problem of crusher blockage problem? The main reason why crusher occurs blockage is material properties. Because the material contains much moisture, the ore material has a certain viscosity. When the ore material is sent to the crusher for crushing into small pieces, the ore material will stick together, and block between two pieces of jaw plates of crushing cavity, then causes material blockage phenomenon; Or the ore material is mixed with a large amount of sticky soil, so that the material is blocked in the crushing cavity. So, how to avoid this blockage phenomenon as soon as possible? Before sending the material to the crusher, we need to screen and dehydrate the material, which can reduce the moisture ...
