CLIRIK raw mill development—from ball mill to vertical mill, vertical roller mill
The ball mill is given priority to high-performance vertical mill, roller machine and so on. Many kinds of mills can be mixed to acquire high yield self-overtaking.
New vertical mill and new technology applications make Grinding process more various and more perfect. Grinding and drying integration is realized. You can even use kiln waste gas as drying heat source
Operating control process has got has high level automation with material analysis, inspection automatic control, ingredients measurement, and operating system control.
New cement vertical mill features:
1. High efficiency
Under the same final size and power, the product capacity of ultrafine mill is twice than jet mill and agitation mill.
2. Longer lifetime of spare parts
The roller and ring are made of special material, which improve the grinding efficiency a lot. For same material and final size, the lifetime of its wearing parts can reach to more than one year, about 2-5 times as long as that of vertical shaft impact crusher and turbo-mill. Especially when handling calcium carbonate and calcite, the lifetime can reach 2-5 years.
3. High safety and reliability:
There are no rolling bearings and bolts in grinding cavity, so problems caused by bolts shedding or wear of bearings and seal components will never happen.
4. High fineness of products
The product fineness can reach D97=<5um.
5. Environment friendly
The application of pulse dust collector and muffler reduce the pollution and noise of the dust, which has reached national environment protection standard.
Cement vertical mill
Cement vertical mill, cement vertical roller mill is last process of cement production, also the most power consumption process. Its main function lies in Grinding cement clinker (and gelling agent, performance adjusting Grinding materials) into suitable particle (by fineness and specific surface area, etc), to form certain particle gradation, increasing its hydration area, accelerating the hydration speed, satisfying the slurry condensation and hardening requirements.
