Grinding Process

Generally, grinding process is continuation of crushing process. And this process often carry out in mills. Grinding mills contain ball mill, rod mill, pebble mill, etc. Grinding process is mainly wet grinding and generally composed of closed circuit with mechanical grading machine. Cement often adopts by dry grinding. Ore is crushed by the grinding media impact and grinding force under the combined effects. Rod mill crushed stone by the function that generated when the bar scroll. Rod mill is not just a point of rod to break the ore, but through the whole rod to crush ore. Therefore,before larger block of ore has not been broken , the rod rarely has impact on fine ore. So we can get relatively uniform particle size of milled products.

Classification:

Grading and screening is different. The former is mainly based on differences in particle moving behavior, the later is mainly based on size comparison. Hydraulic classification principle is: different size, weight and shape particles, according to the flow velocity,can be divided in the different levels. The purpose of classification includes the following three points: 1. check the feed size for subsequent sorting operations.
2. work with grinding equipment to improve the grinding efficiency.
3. washing and cleaning the milled ore. Generally, classification equipments include spiral classifier, hydro cyclone swirler,etc.
With times going on, hydro cyclone swirler has been widely used. The following is working principle of spiral classifier: according to the principle of gravity, milled ore is into spiral classifier, with the slow spiral stirring, lighter material floating on the water while the heavier sink. These sinked particles will be milled again if necessary.
Shanghai zenith is a professional company which can supply perfect ore beneficiation plant. There are many successful cases have been put into use. Shanghai zenith has excellent service. For grinding and classification process, Shanghai Zenith provide ball mill, spiral classifier with different models.
