After crushing stone often used in construction, highways , railways and other related industries to undertake a major force grassroots urban construction , of course, in order to be able to do them better , we must take sand and gravel production line to select it as the weight of the material heavy, after all, this issue after further development of relations with the. Standard production line in the sand , usually by feeder, jaw broken , impact crusher and vibrating screen and other major equipment. Hard materials can be processed , such as processing of basalt, limestone , pebbles and other rock crushing . Then, in the ore crushing process, material processing and how to determine the size of it ?
In the sand and gravel production line is shocked after ore get a huge momentum , and at high speed along the tangential direction pad of the first stage of the back plate thrown by the impact of the role of the back plate , has again been crushed ore , then returned back from the first stage of sheet metal pieces, but also suffered the impact pad again , and continue to give ground . Crushed material , the same high speed again thrown back plate of the second stage , once again been shattered , causing crushing effect "chain " type of material in the counter- crushing machine.
When the ore in commuting between the pads and the back plate , in addition to combating the impact of the role of the board and the back plate , and hit each other several times between the role of the material . Ore into the crushing machine, mainly due to the impact of high-speed rotation of the pad , the ore is along bedding planes , joints surface ore crushing machinery selectively broken. Above this process is repeated until the crushed material particle size smaller than the gap between the pad and the back plate , it is discharged from the lower crushing machine , that is crushed product size . Determination of particle size is key to improving production.
