Stone crushing operations or stone crusher operating principle, the main raw materials in the industrial sector, occupies important position. Stone crushing and grinding of modern operations, the main use of various types of broken machinery and grinding machinery for production.
In the cement industry in the use of raw material and clinker, the need to be broken or crushed by stone crushing machinery or related mining machines such as primary stone crusher of jaw crusher , impact crusher , secondary crusher such as cone crusher , CS cone crusher, vsi crusher etc.
In refractoriness, thermal, chemical, glass, ceramics and construction and industrial sectors, such as roads, crushing processes is also indispensable.
Roll broken bodies made simple and easy to manufacture, in particular, its products have crushed less, so until now is still coal preparation, metallurgy sintering, cement and other industrial sectors. More on the hard and soft ore to China, is broken, especially for the crushing of ore and precious metal ore requirements of the mud at least, they used roll crusher more appropriate.
The rolling breakers roll crusher with the characteristics of the mechanical crusher machinery, with:
(1) small power consumption
(2) broken good size
(3) broken finished high purity
(4) the products have little smash
(5) Simple, easy to operate and so on.
Therefore, the rolling crushers are suitable for the crushing of hard and soft ore, metallurgical and more for sintering, cement, glass, ceramics and other industrial sectors.
The three stages of stone crushing operation
equipment suitable for crushing large lumps as they come from the quarry or mine cannot be used to pulverize to fine powder, so the operation is carried on in three or more stages called primary crushing, secondary crushing, and pulverizing. The three stages are characterized by the size of the feed material, the size of the output product, and the resulting reduction ratio of the material. The crushing-stage output may be screened for greater uniformity of product size.
The reduction of materials such as stone, coal, or slag to a suitable size for their intended uses such as road building, concrete aggregate, or furnace firing. Reduction in size is accomplished by five principal methods:
(1) crushing, a slow application of a large force;
(2) impact, a rapid hard blow as by a hammer;
(3) attrition, a rubbing or abrasion;
(4) sudden release of internal pressure; and
(5) ultrasonic forces. The last two methods are not in common use.
In open-circuit pulverizing, the material passes through the pulverizer once with no removal of fines or recirculation. In closed-circuit pulverizing, the material discharged from the pulverizer is passed through an external classifier where the finished product is removed and the oversize is returned to the pulverizer for further grinding.
