Three ring medium speed micro powder mill

Product features of three ring medium speed micro powder mill

The three ring medium speed micro powder mill can grind the material to an ultra-fine particle size of more than 3000 mesh through fine processing of the material. It is a common equipment for processing ultra-fine powder in the market.

The three ring medium speed micro powder mill is a kind of processing equipment for fine powder and ultra-fine powder. It applies a number of national new mill technologies, with novel design, reasonable structure, small footprint, low power consumption, long operating life, and easy to wear. Low cost and high performance-to-price ratio. Its various technical performances have reached the international level.

This micro powder grinding mill is mainly suitable for non-flammable and explosive brittle materials with medium and low hardness, Mohs hardness lower than 6, such as calcite, chalk, calcium carbonate, kaolin, Bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomaceous earth, barite, gypsum, alunite, graphite, fluorite, phosphate rock stone, potassium ore, pumice, etc. It can be used as a desulfurization mill and pulverizer. At present, the particle size of the finished fine powder of the three ring medium speed micro powder mill can be adjusted arbitrarily between 325-3000 mesh, and the output can reach 0.5-12 tons per hour.

Performance advantage of three ring medium speed micro powder mill

Energy efficient

In the case of the same finished product fineness and motor power, the output is more than double that of jet mill, stirring mill and ball mill.

Long service life of wearing parts

Grinding rollers and grinding rings are forged from special materials, which greatly improves the degree of utilization. Generally, it can reach more than one year. When processing calcium carbonate and calcite, the service life can reach 2-5 years.

High safety and reliability

Because there is no rolling bearing and no screw in the grinding chamber, there is no problem of easy damage to the bearing and its seal, and no problem that the screw is easy to loose and damage the machine.

Environmental protection and clean

The pulse dust collector is used to capture dust, and the muffler is used to reduce noise, which has the characteristics of environmental protection and cleanliness.

Structure composition of three ring medium speed micro powder mill

The complete configuration of the ultrafine powder grinding mill includes hammer crusher, bucket elevator, storage bin, vibrating feeder, micropowder mill host, frequency conversion classifier, double cyclone powder collector, pulse dust removal system, high pressure fan, air compressor machine, electrical control system.

Working principle of three ring medium speed micro powder mill

The three ring medium speed micro powder mill breaks the bulk material into small particles by the hammer crusher, and then is sent to the storage bin by the elevator, and then the material is evenly sent to the turntable through the vibrating feeder and the inclined feeding pipe. on the upper bulk pan. Under the action of centrifugal force, the material is dispersed to the periphery of the circle, and falls into the raceway of the grinding ring, is impacted, rolled and ground by the ring roller, and becomes powder after being processed by the three-layer ring.

The high-pressure fan sucks the external air Inhale into the machine, and bring the crushed material into the powder classifier. The rotating impeller in the ultra-fine powder mill powder selector makes the coarse material fall back and regrind, and the fine powder that meets the requirements enters the cyclone powder collector with the airflow and is discharged from the discharge valve at the lower part to become the finished product, with a small amount The airflow of fine dust passes through the pulse dust collector and then is discharged through the fan and muffler.

Product precautions of three ring medium speed micro powder mill

1. Check the bearing temperature frequently. If the temperature is too high, check whether the lubrication and transmission parts are normal, whether the rolling distance is too tight, etc. Find out the reason in time and take corresponding measures. If the situation is serious, stop the machine for inspection.

2. Always check the tightness of the transmission belt. If the belt is too loose, it will reduce the transmission efficiency and affect the grinding effect. If it is too tight, it will easily cause the bearing to heat up, increase power consumption, and reduce the service life of the transmission belt.

3. Various transmission parts must be fastened and reliable. Special tools should be used for disassembly or installation, and direct hitting with hand hammers and other tools is prohibited.

4. Do not forget to check the pneumatic components. After starting the plastic mill, you should always check the pneumatic components in the air circuit, whether there is air leakage or damage in the air circuit and connections, and at the same time check whether the air supply pressure meets the requirements. The use of the machine should also be checked frequently. If it is found to be too tight, too loose, jumping, deviation, serious wear, etc., it should be adjusted, repaired or replaced in time. The oil storage capacity of the lubricator in the air source triplet should be checked regularly, and 20# spindle oil must be added to prevent the small holes in the pipeline from being blocked.
