Augite/pyroxene ultra fine mill

Augite is very dark green to black in color. The diagnostic feature of any pyroxene is two cleavages that intersect at 89° or 91°. Unlike the feldspars or hornblende, pyroxenes show mediocre cleavages that are hard to spot.

 

Introduce Of Augite/pyroxene ultra fine mill:

Augite/pyroxene ultra fine mill 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, basalt, calcite, marble, talcum, barite, gypsum, dolomite, bentonite mud, mica, pyrophyllite, sepiolite, carbon black, diatomite, graphite, alunite, fluorite, potassium feldspar, phosphorite, pigment, up to 200 kinds. The granularity (or final size) of the finished products can be freely adjusted between 325-3000meshes (0.045-0.005mm), and the capacity (ton/hour) ranges from 0.4T/H to12T/H depending on the final size and the grinding materials.

 

Detailed Product Description about Augite/pyroxene ultra fine mill

Augite/pyroxene 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, Augite/pyroxene 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 Augite/pyroxene ultra fine mill:

The whole set HGM Augite/pyroxene 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 Augite/pyroxene 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.
 

Features of Augite/pyroxene ultra fine mill:

1. High efficiency
Under the same final size and power, the product capacity of Augite/pyroxene ultra fine 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≤5μm.

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.
