Crusher Plant Layout Mining Operation Process

In cement production process, the mining of limestone, clay, sandstone, gypsum, coal, mixing materials, and fuels, as well as clinker (sometimes with pieces of large clinker), need to be crushing, grinding, drying, transportation and storage.

As the production capacity of kilns, grinding supplier, such as single large combined mining technology development, crushing processe, and devices also have greater development. A crusher plant layout has many important features in mining process:

(1) Crushing enlarged equipment;
(2) Crushing flow sheets single segment;
(3) Crushing equipment of mobile;
(4) Crusher multifunctional.

According to the requirements yield, crushing ratio, material of physical properties and crusher character to choose the characteristics of crushing system section number and appropriate crusher.

System selection

1. The material properties

Material of hardness, water, shape and impurity content will directly influence the breakage of economic and technical index system, the selected system must be broken material with the physical properties of adaptation.

2. Material size

(1) Feed block; (2) Discharging size; (3)Crushing ratio

Feed block

Maximum feed size of crushing system of mining the maximum block size. Crusher plant layout depends on the size of factories, mines blasting method, loading equipment, unloading equipment and the type and specification crushers.

Because the factories the size of the different requirements of different blasting methods, large scale with a massive blast. So maximum feed size is related factory scale.

Large and medium volume is relative to the size of the factory. When use excavator loading, limestone maximum block size with excavator shovel bucket is as follows:

Bucket volume(m3)	0.5	0.8	1.0	2.0～2.5	3.0～4.0
Maximum block feed size(mm)	400	450	650	800	9001100

Small limestone in cement plant using artificial, its maximum feed size <350mm.

Different specifications and types of crusher for maximum feed size requirements are also different, cone Crusher and jaw crusher maximum feed size is 80~85%. Inversed impact crusher, hammer crusher, roller crusher for maximum feed size by crushing process (coarse, medium and fine crushing) and material reality.

Various material feed size

Material Name	Maximum Block Feed Size(mm)
Material Name	Large Factory > 50(million tons cement/a)	Medium Factory 10~50	Small Factory < 10
Limestone	800~1000	600~800	300~600
Clay, Sandstone	400	400	250
Clinker	100	100	200~300
Gypsum	300	300	300
Coal	300	300	300

Discharging granularity: Depending on the production process on crushing material particle size requirements. Best leaves the material granularity is the output of the crusher and mill are high and low power consumption results.

Determine the most suitable size of the basic principles: High hardness and Grindability of difference materials, discharge fine; granularity do not align, coarse material more material discharge fine; dry and open circuit grinding, material fine; different types of mill for limestone feed size requirements are different. Ball mills and pipe mill requires a fine: 15~25mm; single cartridge grinding more fine than two-cartridge and multy-cartridge; baseball ground can appropriate to relax size: 20~40mm; the wheel roll is coarse: 50~100mm; no media mill at 150~300mm.
