Carbon black/ furnace black stone ultra fine mill

Carbon black (also known as acetylene black, channel black, and furnace black, lamp black or thermal black) is a material produced by the incomplete combustion of heavy petroleum products such as FCC tar, coal tar, ethylene cracking tar, and a small amount from vegetable oil.

The most common use (70%) of carbon black is as a pigment and reinforcing phase in automobile tires. Carbon black also helps conduct heat away from the tread and belt area of the tire, reducing thermal damage and increasing tire life. Carbon black particles are also employed in some radar absorbent materials and in photocopier and laser printer toner.

Carbon black stone ultra fine mill is a new type machine to grind Carbon black  into super thin Powder.

The final Powder size can be from 5micron to 47micron as per 97% passing rate.



Carbon black stone ultra fine mill is mainly applied to non-inflammable, non-explosive and brittle materials with Mohs' hardness scale under seven, such as calcite, chalk, limestone, dolomite, carbon black, bentonite, kaolin, talc, mica, magnesite, illite, pyrophyllite , roseite, sea-foam, attapulgite , rectorite, diatomite, barite, gypsum, alunite, graphite, fluorite,  rock phosphate, kalium ore, pumice etc. totally more than 100 kinds of materials.

Finished powder products are in the 325meshs -3000meshs, and yield can be up to 0.5-12 tons per hour. There are five types of Shanghai CLIRIK HGM series carbon black stone ultra fine mill; they are HGM80, HGM90, HGM100, HGM100A and HGM125.
 

Detailed Product Description about Carbon black stone ultra fine mill:

Carbon black stone ultra fine mill is mainly applied to grind non-inflammable, non-explosive and brittle materials with Mohs’ hardness under six. Such as calcite, chalk, limestone, dolomite, kaolin, gypsum, and talc etc, totally more than 100 kinds of materials. Product fineness can be controlled between 300~3000 mesh (47~5 micron) 

Comparable with ball mill, Carbon black stone ultra fine mill has features of low cost, high capacity, easy operation; Comparable with Raymond mill for coarse powder up to 325 meshes, it can produce fine powders between 47 and 5 microns (300 to 3000 meshes)
 

Production Line Configuration of Carbon black stone ultra fine mill:

The whole set HGM Carbon black stone ultra fine mill consists of  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

Working Principle of Carbon black stone ultra fine mill:

The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of rollers, which are rolling in the ring, are driven by dial through plunger. After 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 first dial evenly by the electromagnetic vibrating feeder and feeding pipe. The materials will be driven to the edge of 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 classifier. The rotating turbo in the powder concentrator will make the coarse powder 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.
 

Performance and features of Carbon black stone ultra fine mill:

1. High efficiency
Under the same final size and power, the product capacity of micro powder stone ultra fine mill is twice than jet mill and agitation mill.

2. Long lifetime of wearing 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 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≤5μm.

5. Environment friendly
The application of DMC-120 pulse dust collector and muffler reduce the pollution and noise of the dust, which has reached national environment protection standard
