Limestone Application

Limestone is one of important raw material of producing cement, lime and calcium carbide, After being grinded into ultrafine powder, milling, the limestone powder is widely used in the production of products like paper-making, rubber, paint, coating, medicine, cosmetic, etc.

The recommended Limestone grinding mill is HGM Series Ultra Fine Grinding Mill, which absorbed European manufacturing technology, meets client’s requirements of excellent fineness, environment-friendly, reliable performance and favorable price.

Advantages of ultra fine grinding mill:

1.High fineness, flexible adjustment.

The final fineness of calcium carbonate ulra fine grinding mill can be adjusted between 325 meshes and 2500 mesh (47-5 micron), and the product fineness can reach D97≤5μm

2.High Efficiency.

Under the same finished final size and the same motor power, the capacity of calcium carbonate ulra fine grinding mill is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%.

3.Long lifecycle of spare parts.

The ring and roller are forged by special material with high utilization,the lifetime can reach 2-5 years for grinding calcium carbonate.

4.High safety and reliability.

As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.

5.Environment-friendly. There are sound-proof house and muffler to reduce noise, dust cleaner to avoid dust flying outsize. 

Limestone Grinding Processing Line

Whole grinding line: crusher(hammer or jaw crusher or others) + elevator + hopper + feeder +  main unit grinder + cyclone power collector + pulve bag dust cleaner + blower + muffler + sound-proof house

Stage 1. Limestone are transported into crusher by truck and crushed into small particle size, and then lifted into storage silo of main machine by bucket elevator.

Stage 2. Limestone comes from hopper and feed into main mill uniformly by vibrating feeder, then goes into pipes.

Stage 3. In the grinding process, qualified final product after screening system will go into powder collector, and then go out from outlet. Unqualified product will go back to main mill and regrind until it get the needed size.

Stage 4. The air flow after purification will go into fan from pipes that up the bag filter
