Limestone

Introduce of Limestone Powder grinding plant:

The Limestone Powder grinding plant mainly consist of a hammer crusher, limestone powder grinding mill main unit, Frequency conversion classifier, powder collector, pulse dust cleaner, high pressure positive blower, air compressor, muffler, electrical apparatus control system, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.


The purpose of Limestone Powder grinding plant is for super-fine grinding materials with hardness less than 6 in Moh’s scale and humidity less than 6 percent such as kaolin, limestone, calcite, marble, talcum, barite, gypsum, dolomite, bentonite mud, mica, pyrophyllite, sepiolite, diatomite, graphite, alunite, fluorite, potassium feldspar, phosphorite, pigment and so on. The granularity of the end products is 150-3000 meshes (0.104-0.004mm).

Models of Limestone Powder grinding plant:

Limestone grinding mill models: HGM80/HGM90/HGM100/HGM125/HGM1680
Finished limestone powder fineness: 104-4 micron (150mesh-3000mesh)
Capacity: 0.5-45 tons per hour
Input limestone size: ≤20mm

Working Principle of Limestone Powder grinding plant:

The main bearing and each dial are driven by the electromotor of the main machine through the reducer, and a number of rollers, which are rolling in the ring, are driven by the dial through the plunger. After being crushed by hammer crusher, the big materials become small ones and are sent to storage hopper by elevator and further sent to the middle of the first dial evenly by the electromagnetic vibrating feeder and feeding pipe. The materials will be driven to the edge of the dial by centrifugal force and fall down into the ring, crushed and grinded by roller, and become powder after production of three rings. The high-pressure centrifugal blower will inhale air from outside and blow the crushed materials to the classifier. The rotating turbo in the powder concentrator will make the coarse materials return to the mill and reground, while the fineness will mix with the air and go into the cyclone and be discharged in the discharge bin, which is at the bottom of it. The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler.

Production Line Configuration of Limestone Powder grinding plant:

Hammer crusher, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, cyclone collector, pulse deduster system, high pressure positive blower, air compressors, and electrical control systems.

Technical Advantages of Limestone Powder grinding plant:

● High Efficiency


Under the same finished final size and the same motor power, the capacity of the HGM series limestone powder grinding mill is twice as much as jet mill, mixing grinder, and ball mill, and energy consumption decreased 30%.


● Long lifecycle of spare parts


The ring and roller are forged by special material with high utilization. Under the same grinding material and finish special size, the lifecycle of spare parts is about one year, which is 2-3 times longer than an impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate.


● High safety and reliability


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


● High fineness, flexible adjustment


The final fineness of the grinding materials can be adjusted between 150 mesh and 3000 mesh (104-4 microns), and the product fineness can reach D97≤5μm.


●Environment-friendly


The application of pulse bag filters and mufflers greatly alleviates dust pollution and noise.


●The advanced intelligent speed control device


Convenient adjusting, more uniform particle size.
