In some cases, the first and second crushing work does not need the prescreening. For the three stage open-circuit crushing process, the final stage is open-circuit so the particle size requirements of crushing products are hardly to be guaranteed. So the large dressing plants often process the ore stones with high water content.
Impact stone crushing machine such as vertical impact crusher is the second stage of crushing machinery, can handle particle size of not more than 120-350mm, and the crushing strength of not more than 320 MPa granite, basalt, limestone and other stone. The crusher with crushing ratio, high crushing efficiency, easy maintenance features, crushed stone cube, and the device of choice for the production of high-quality stone is a senior highway, railway, water conservancy, airport, construction and other industries.
The three stage crushing process is the most commonly used crushing and sieving process in dressing plants. This process can be classified into three stage open-circuit crushing and the three stage closed-circuit crushing. In two stage and three stage process, each crushing work is equipped with prescreening to enhance the production capacity of mining crusher and avoid the ore mud’s blocking.
For the two crushing process, most of the dressing plants will use two stage closed-circuit crushing process, which is the two stage crusher and the sieving machine form the closed-circuit producing. This process will guarantee the particle size requirements of crushing products and will not influence the ball mill grinding work.
The two stage crushing process can be classified into two stage open-circuit crushing and the two stage closed-circuit crushing. The open-circuit crushing is the crushing products don’t need to come back this stage crushing work for being crushed again; the closed-circuit crushing is that: after the crushing products are sieved, the products with unqualified particle size (the products on the screen) will come back this stage crushing work to be crushed again.
Parts selection at reasonable structure design, long service life, and the broken product particle size uniformity, reducing the hydraulic clean cavity system, reduces downtime, and buy more specifications crusher cavity, the user depending on the needs of a choose different type of chamber, in order to better adapt to user needs.
Cone stone crushing machine such as cone crusher is widely used in metallurgical industry, building materials industry, road building industry, chemical industry in the silicate industry, suitable for crushing of medium or above hardness ore and stone. The crusher with crushing force, high efficiency, high handling capacity, low operation cost, easy adjustment, economic features.
