In the production of crushing, screening consists of coarse, medium and fine and ultra-fine crushing process is often referred to as a broken screen flow, hereinafter referred to as crushing process. The crushing process technology of all kinds of mines is various, but often have so few things in common:
1. To the broken process corresponding segmentation processing;
2. Work closely crushing and screening;
3. The whole section with broken section as the basic unit, divided into coarse crushing, the broken section and finely and ultra fine grinding.
According to the broken section to achieve the size and demand is different, according to the corresponding situation usually choose different crushing and screening equipment. Super fine crushing section is mainly in order to get more fine material products. Process of different crushing process difference lies in the number of broken section, equipment and screening system configuration and function are different. The second and the third paragraph is the most commonly used process.
Two stage crushing process mainly include both open and closed. For imported material particle size in 200-400 mm, the product particle size small mine concentrator in 12-30 mm is very practical. In some cases the first a crushing workload is small, then can be screen in advance, not in front of the broken directly using two paragraphs closed-circuit crushing process. The use of two pieces of broken open, mainly found in certain re-election factory or need to be broken after the material directly sent to the mill small mill.
Three sections of the process is divided into open and closed two kinds. Closed-circuit process under the condition of the ore silt content is not high ability to adapt is stronger, so in all kinds of industries and the size of the refinery as a process is widely used for the grinding. Three broken open process workshop equipment is relatively simple, can save some corresponding construction cost. But due to the production of finished product material are relatively coarse, so is usually used to deal with the circumstance of space limitation low moisture content of clay mineral, or when the grinding feed particle size requirements of the tender process.
Some mineral crushing, as a result of the ore contains a lot of mud, if use normal crushing process is hard to meet the conditions of production. This case often use contains the crushing process of washing procedures. Before, during and after the coarse crushing on the material to the material washing and fine mud treatment accordingly. According to corresponding specific production process of different crushing process design accordingly.
