We use quality stone to pave road, it not only has the natural good mechanical index, but its particle showing cube-shaped and multi-angular after crushing so as to ensure the close combination in the stone and improve the overall strength of the road. In addition, the surface of the stone show multi-angular and rough texture, which can be bonded with the asphalt firmly, so the strength and durability of the pavement is better. For the entire production of ore exploiting, it is very important to control the finished product content of the flat-shaped and prolate-shaped particles, which can ensure overall product quality standards.

1. Ratio of reduction: ratio of reduction is size percentage of material to be feed and the finished material. When the ratio is larger, the ratio of reduction is greater. This rule not only apply jaw crusher not also cone crusher. Ratio of reduction has nothing to do with the crusher models, but if the ration of reduction is too small, it can lead to reduce output, increase internal recycle and the wear of the crusher, so the economy is poor and the production efficiency is low. Therefore, it is very important to choose the right ration of reduction in the entire production progress.

2. Size of input granules: when the feed size reduce from 100mm to 50mm, flakiness content of the finished compound decreased by 38%.

3. Cyclic Loading To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery, like stone production line, Henan Hongxing is always doing the best in products and service.shaking concentrator:http://www.hx-crusher.com/concentrator_table.html

In the process of closed loop production, increasing discharge opening and cyclic load make stone grain better, because cyclic load increased can lead to the wear of system equipment. But when the discharge opening transfer larger, the main motor load of crusher can reduce, which make the finished feed grain better.

4. Open and closed circulation

In the secondary crushing process, circulation is divided into open circulation and closed circulation. Open circulation is the first screening after crushing, which refers to that the primary broken material is screened by vibrating screen and enters into the feeder of the secondary crushing ,so that the finished material production and flakiness content increased, closed circulation is the first crushing after screening, which refers to that the primary broken material enters into the secondary crushing feeder entirely and crushed, and then screened by vibrating screen. The entire system has no material loss, and the product of grain shape is better.

In addition, the right grain shape is than the discharge opening is in accordance with the finished material particle size. Discharge opening is large than the particle size, which is lower than that discharge opening is less than flakiness content. This is because when discharge opening for the same as feeder is small, the ration of reduction is large, so the particle shape appears variation.
