Micro Powder Grinding Mill

Micro Powder Grinding Mill is equipment designed for customers who need to make ultra-fine powder. This machine is equipped with efficient pulse dust collector and muffler, which can reduce dust and noise. And the whole production won’t take effect on environment. Manufacturer Mineral Grinding Mill Marble ,Micro Powder Mill is specially designed for micro-powder making. Nowadays, micro-powder is widely used in many industries, like sopa, toothpaste, cosmetics, rubber, paint, paper, PVC, glass, etc. It can be used for non-metallic ores like limestone, calcite, kaolin, talc, illite, etc.


What are the structural components and applications of the micro powder grinding mill( three-ring mill)?

The three-ring grinding ore material can be widely used in chemical, glass, metallurgy and refractory materials, making it a good hand in the milling industry. The three-ring grinding can meet the processing needs of all aspects of the market, Winnermac company Adhere to innovation, a new generation of three-ring grinding.

The structure and application of the new three-ring mill are mainly embodied in the following: the dolomite production line usually has a hammer crusher, a bucket elevator, a storage bin, a vibrating feeder, a dolomite mill host, a frequency conversion classifier, and a double cyclone. Powder collector, pulse dust removal system, high pressure fan, air compressor, electrical control system and other components. In addition to processing dolomite, it can also process ultra-fine powder processing of non-inflammable and explosive brittle materials with medium and low hardness and Mohs hardness ≤6, such as calcite, chalk, limestone and dolomite. .

The three-ring mill uses a unique processing technology to process the dolomite ,from raw mineral material into a uniform particle size of 300 mesh to 3000 mesh, which is also super-powerful in energy saving. Built-in precision classifier to achieve fine powder collection, professional configuration of pulse dust collector, muffler, good environmental performance.

What is the working principle of the three-ring grinding?

The three-ring grinding machine is mainly composed of main machine, powder separator, dust collector, dust collector, fan, muffler, soundproof room, crusher, hoist, silo, feeder, etc. It is widely used in the ultra-fine grinding industry. The equipment, below to introduce to you the specific working principle of the three ring grinding: During the operation of the three-ring grinding process, the bulk material is broken into small particles by the crusher, and then sent to the storage bin by the bucket elevator, and then the vibrating feeder and the inclined guiding pipe are sent to the main machine’s turntable upper bulk plate evenly. When the three-ring grinding mill work, the main motor drives the main shaft and the turntable through the reducer, and the turntable passes through the edge of the roller pin to drive dozens of grinding rolls to rotate and roll in the grinding ring raceway. The material is scattered to the periphery under the action of centrifugal force, and falls into the mill cavity, which is impacted, rolled and ground by the grinding roller in the loop of the grinding ring. It is repeatedly ground into a powder through a three- or four-layer loop. The high-pressure fan draws outside air into the machine through suction and brings the pulverized material into the classifier. The high-speed rotating impeller screens it, and the unqualified coarse powder falls back to re-grind. The qualified fine powder enters the cyclone dust collector with the airflow, and the dust falls, which is discharged from the bottom discharge valve. A small portion of the fine dust enters the dust collector with the airflow and adheres to the surface of the filter bag. The pulse valve controls the high-pressure airflow to be instantaneously sprayed from the inside of the filter bag. The dust adhering to it will fall due to the sudden shaking of the filter bag, and the conveyor at the bottom will send the two collected fine powder materials out for the finished product packaging. The filtered clean air is finally removed at the muffler outlet.

1. Three-ring grinding mill is efficient and low-cost. In the case of the same material, power, and fineness of the finished product, the output is 40% higher than that of the jet mill and the agitator mill.

2. The three-ring micronized powder mill has a long service life. In the case of the same fineness of materials and finished products, the wear parts of the impact pulverizer and the turbo pulverizer have a longer service life, generally up to one year.

3. There are no rolling bearings and no screws in the grinding chamber. There are no problems such as the bearing and its seals and the fragile screws are easy to loosen and destroy the machine.

4. The fineness of the tricyclic grinding product can reach d97≤5μm at one time.

Technical advantages
1. Low investment costs. In the case of the same fineness, the injection is less than the airflow mill, the cost is low, and the recovery cycle is short.
2. The powder extraction rate is high. Under the same fineness and power consumption of the finished product, the output is more than 45% higher than that of the jet mill and the agitator mill.
3. Low loss of wearing parts. All wearing parts are made of high-quality wear-resistant materials at home and abroad, which are longer than the wear parts of ordinary mill equipment, and can generally last for more than one year.
4. The operation inside the grinding chamber is safe and reliable. Compared with the ordinary mill, the ultra-fine grinding has no rolling bearing and no screw in the grinding cavity, so there is no problem that the bearing and other sealing parts are vulnerable, and the problem that the screw is loose and the machine is destroyed is avoided.
