Rod mill Manufactured Sand Process Description

Modern gravel production technology advances, sand craft a variety of forms, a common is rod mill manufactured sand, impact crusher manufactured sand on comparative analysis of different sand processes.

rod mill
1, rod mill manufactured sand
Sand rotating rod mill is driven by the rotation of the rod mill rod mill in bars, drops and other sports, to enter the rod mill in sand rock extrusion, grinding, impact and get sand material.
Advantages rod mill sand is sand shape better, especially the particle size distribution of stable sand fineness modulus can be artificially controlled. The disadvantage is that energy, steel consumption, water consumption, low yield, high cost, is not suitable for large-scale production of sand and gravel plant.
2, vertical shaft impact crusher manufactured sand
Vertical shaft impact crusher crushing methods are based on two models. One is the “rock stone” crusher; the other is the “stone blacksmith” crusher.
They all have large crushing ratio, grain shape is good, handling large and small civil engineering and installation engineering, operation and low cost. In particular, stand-alone processing capacity, to overcome the problem of low yield rod mill. Currently vertical shaft impact crusher used in domestic processing capacity is generally 250 ~ 300t / h, about 40% into the sand, sand production that is a stand-alone 100 ~ 120t / h, and can produce according to need, and stone. The disadvantage is that coarse particle size, particle size distribution is not reasonable, can not meet the production needs.
3, vertical shaft impact crusher and rod mill joint manufactured sand
The joint application process in a sand gravel plant.
The system is working normal concrete design requirements sand fineness modulus 2.6 + 0.2, powder content of 10% to 14%. After commissioning the system capacity vertical shaft impact crusher hourly output 442t, rod mill hour output 205t. Meet the peak month for 390 000 t of sand needed to meet the...
