Limestone is widely used in the cement and chemical industry. After mining, it needs to be processed into 12, 13, 24 or 05 stones before being put into use. What crusher equipment should be used in the production of limestone processing? The nature of limestone is relatively soft, the selection range is relatively wide when choosing limestone crusher, so how to choose the crusher equipment with high cost performance? Let’s take a look.
The limestone production line mainly has the following stages: coarse crushing system – medium crushing system – fine crushing system. The main equipment used in the coarse crushing system is jaw crusher, the impact crusher is used in the medium crushing system, and the sand making machine is used in the fine crushing system.
Jaw crusher in the processing of limestone, through the movable jaw plate on the material mutual extrusion to complete the crushing operation, simple operation, durable, and high performance. Jaw crusher has complete models, and high efficiency. The connecting rod bearing, eccentric shaft bearing and thrust plate elbow head of jaw crusher are lubricated with lubricating oil. It is an economical limestone crusher.
The impact crusher is used in the secondary crushing stage in the limestone production line. Through the impact plate, plate hammer and rotor, the limestone falling into the crushing cavity can be finely crushed under the impact force. The feed port is large and the amount of throughput is large. Because of the dependence on plate hammer and rotor, it is more suitable for the grinding of limestone with low hardness and reduces the wear and tear of wearing parts. The discharging particle size of impact crusher is adjusted by adjusting the clearance between the hammer plate and the rotor, convenient for users to meet the needs of the finished product size.
Sand making machine is specially designed to crush finely crushed limestone into building sand between 1-5mm. According to different production methods, the sand making machine is divided into PLS vertical impact crusher and PFL vertical composite crusher. Vertical impact crusher adopts the whole center feeding and surrounding feeding mode, so that the limestone fully enters the crushing chamber, and pulverized sand making according to the characteristics of stone. It has the advantages of shaping sand, reduces the needle flake stone, and the discharging grain size is uniform and the grain shape is more in line with the construction sand standard.
