Product Description

Introduction to micro powder:
with the development of high-tech industry, micro powder is widely applied in various fields, and the demand for micro powder is ever-increasing. Daily used soaps, toothpastes, cosmetics, plastic films, PVC, rubbers, glass, fire retardants, high hardness grinding materials, building materials, chemicals, etc are closely related with micro powder.


Application of Micro powder
Micro powder is crushed and grinded mainly from non-metallic minerals, hard stones and organics. The grinding materials include kaolins, limestones, calcite, marbles, barites, gypsums, pyrophyllites, dolomites, calcium carbonates, pigments, clays, coals, activated carbons, feldspar, talcs, mica, carbon black, petroleum coke, alumina, chromic oxide, quartz, cements, up to 100 materials. Meanwhile, micro powder can enlarge its application in other fields when ultrafine micro powder is modified. Besides, micro power can not only be used as excellent filling materials, but also improve products' performances such as strength, elasticity, abrasive resistance, high temperature resistance, aging resistance, radiation protection, which, in turn, reduces the cost of production.

Introduction to three-ring Micro Powder Mill
SCM Series Three-ring Micro Powder Mill is the equipment specializing in producing fine and superfine powder of non-inflammable, non-explosive and brittle materials with Mohs's hardness under six, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite and vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, alunite, graphite, fluorite, rock phosphate, Kalium ore, pumice, etc., totally more than 100 kinds of materials.

Working principle of three-ring Micro Powder Mill:
SCM series three-ring Micro Powder Mill mainly consist of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.

After crushed by hammer crusher, the large materials become small ones and are sent to storage hopper by elevator, and then evenly sent to the upper distribution plate of the turnplate by vibrating feeder and sloping feeding pipe.

When the grinding mill is at work, all the grinding rollers are rolling in the ring, and the materials are driven to the edge of the turnplate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers.

The high-pressure air blower constantly inhales air within the grinding mill and, in turn, the airflow with crushed materials are brought to the classifier whose high-speed impeller will screen the airflow: The unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector. Most of the qualified powders will fall and exit from the discharging valve at the bottom; A small proportion of the fine powders, with airflow, moves to the dust cleaner, and clings to the surface of the filter bags.

At the same time, the fine powders clinging to the surface fall down by the sudden vibration of the filter bags, which is caused by the instantly ejected high-pressure gas controlled by the pulse valve. The materials from the above two lots are sent by the conveyor at the bottom to get finished powders packed. In addition, filtered clean air will be emitted from the air outlet of muffler in the end.

FAQ

1. What advantages does your ultrafine mill have? 

-The main advantage of our ultrafine grinding mill over other kinds of mills is that you can grind a friable or crystalline material to 5 - 47 microns average particle size and classify in a very narrow particle size range at the same time. There are no moving parts to wear out or generate heat in our mill and no screens to plug or be punctured.

 

2. Can you guarantee the quality of your ultrafine grinding mill?

---We have passed CE&ISO9001:2008, and our crushers have been exported to Eastern Europe, Middle East, Africa, South Asia, Southeast Asia, Oceania, America, etc.

 

3.How many years have you been manufacturing the machine?

---8 years. Since the foudation of our company, we have been manufacturing the machine, which updated many times, now the machine runs stable and of high quality

 

4. How do you adjust particle size in your ultrafine grinding mill?

-Particle size is adjusted primarily by a change in feed rate. When the rate is reduced, finer particles result because there is more energy available per particle to accelerate the particles and the entire fluid mass. Collisions become more violent and pressure gradients become larger.
