Ultrafine grinding mill is mainly suitable for processing ultrafine powder of non-flammable and explosive brittle materials with medium and low hardness, Mohs hardness ≤7, such as calcite, chalk, limestone, dolomite, carbon black, kaolin, Bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomaceous earth, barite, gypsum, alunite, graphite, fluorite, phosphate rock, potash ore, pumice, etc. 

The granularity of the fine powder product can be adjusted between 325-3000 mesh.

HGM ultrafine grinding mill

The particle size of the fine powder processed by the ultra-fine mill can be adjusted arbitrarily between 325 mesh and 2500 mesh.

The full set of configuration includes hammer crusher, bucket elevator, storage bin, vibrating feeder, micro-grinding host, frequency conversion classifier, double cyclone powder collector, pulse dust removal system, high-pressure fan, air compressor, power control system.

Performance characteristics

1. Efficient and energy-saving

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

2. Long service life of wearing parts.

The grinding roller and grinding ring are forged with special materials, which greatly improves the utilization.

In the case of the same fineness of materials and finished products, the service life is 2-5 times longer than the wear parts of impact crushers and turbo crushers, generally up to more than one year.

When processing calcium carbonate and calcite, the service life can reach 2 -5 years.

3. High safety and reliability.

Because there are no rolling bearings and no screws in the grinding cavity, there is no problem that the bearings and their seals are easily damaged, and there is no problem that the screws are easy to loosen and damage the machine.

4. High product fineness

The fineness of HGM ultra-fine grinding mill can reach D97≤5μm at one time.

5. Environmental protection and cleanliness

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

The complete configuration of ultra-fine mill includes hammer crusher, bucket elevator, storage bin, vibrating feeder, micro-grinding host, frequency conversion classifier, double cyclone powder collector, pulse dust removal system, high-pressure fan, air Compressor and electrical control system.

Matters needing attention

1. Check before starting up. When using this kind of milling equipment, you must check before starting up. Carefully check all aspects of the motor, air cylinder, feeding area, blast pipe, etc., to ensure that the entire machine is unblocked. Then turn on the switch to feed and grind. 　　

2. Clean up every day. After every day, the superfine mill must be cleaned up in time to remove all the floating powder on the surface and the broken slag in the corners. You can use a brush to help in some places that are difficult to clean. Brushing and keeping good habits every day can effectively extend the service life of the mill. 　　

3. Timely lubrication. During more than two hours of use, we need to perform a lubrication operation on the mill, and drip the special mill lubricating oil from the special valve and continuous port, which can effectively maintain the stable operation of the machine , At the same time, several parts are well protected from damage and deformation. 　　

4. The feeding material must be handled well to protect the superfine grinding to be more healthy, long-term, and not easy to wear. Another good way is to handle the feeding function, and perform some rough screening of the material entering the grinder, and select the size of the particles to be more uniform. A batch of materials enter the grinder, so that its grinding plate and grinding can reduce frictional resistance and loss.

Working principle

When working, the main motor drives the main shaft and the turntable to rotate through the reducer, and the roller pins on the edge of the turntable drive dozens of grinding rollers to roll in the grinding ring raceway. The bulk material is crushed into small particles by the hammer crusher, and then sent to the storage bin by the elevator, and then sent to the bulk tray on the upper part of the turntable evenly through the vibrating feeder and the inclined feeding pipe. The material is scattered to the periphery of the circle under the action of centrifugal force, and falls into the raceway of the grinding ring, and is impacted, rolled, and ground by the ring roller. After three-layer ring processing, it becomes powder. The high-pressure fan removes the external air through suction. Inhale into the machine, and bring the crushed material into the powder concentrator. The rotating impeller in the powder classifier makes the coarse materials fall back and regrind. The fine powder that meets the requirements enters the cyclone powder collector with the airflow and is discharged by the discharge valve at the lower part of the cyclone as the finished product, while the airflow with a small amount of fine dust passes through After the pulse dust collector is purified, it is discharged through a fan and a muffler.
