Advantages of ultrafine mill

Energy efficient

The SCM series ultra-fine powder mill is more than twice as high as the flow mill, the agitator mill and the ball mill under the same fineness of the finished product and the motor power.

Consumable parts have a long service life

The grinding roller and the grinding ring are forged by special materials, so that the utilization degree is greatly improved. In the case of the same material and finished product fineness, the wear life of the impact crusher and the turbo crusher is 2-5 times longer, generally more than one year. When processing calcium carbonate and calcite, the service life can reach 2 -5 years.

Environmentally friendly, clean

The SCM series ultra-fine powder mill uses a pulse dust collector to capture dust, and uses a muffler to reduce noise. It is environmentally friendly and clean.

High safety and reliability

SCM series ultra-fine powder grinding machine has no rolling bearing and no screw in the grinding chamber, so there is no problem that the bearing and its sealing parts are vulnerable. There is no problem that the screw is easy to loose and destroy the machine.

High product fineness

The fineness of SCM series ultra-fine powder mill can reach D97≤5μm at one time.

Working principle of ultrafine mill

The large material of SCM series ultra-fine powder mill is broken into small particles by hammer crusher and then sent to the storage bin by the hoist. Then the material is evenly sent to the turntable through the vibration feeder and the inclined feeding pipe. The upper part of the bulk tray.

The material is scattered to the circumference of the circle under the action of centrifugal force, and falls into the raceway of the grinding ring, which is impacted, rolled and ground by the ring roller, processed into a powder through the processing of the three-layer loop, and the high-pressure fan passes the external air through suction. Inhaled into the machine and the pulverized material is brought into the classifier.

The rotating impeller in the SCM series ultra-fine powder mill is used to re-grind the coarse material. The fine powder that meets the requirements enters the cyclone powder collector with the airflow and is discharged from the lower discharge valve. The airflow with a small amount of fine dust is purified by a pulse dust collector and then discharged through a fan and a muffler.

How to solve the problem of ultrafine mill dust

As an important choice for ore milling equipment, ultra-fine grinding machine often has a large amount of dust in the operation, which will not only cause damage to the ecological environment, but also seriously endanger the health of the staff. How to effectively solve the problem of ultra-fine grinding machine dust is an urgent problem for users of ultra-fine grinding machines. Shanghai Collierk tells you that the ultra-fine mill dust solution is not a problem.

ultrafine mill

In order to effectively solve the dust problem of the ultra-fine mill, we should have a detailed understanding of the causes of dust generation. Let's take a look at the reasons for the dust of the ultra-fine mill.

1. Analysis of dust spots

The dust source mainly comes from the feed port, the discharge port and the conveying system. After the material to be processed is ground by the ultra-fine mill, it is sent to the next step through the conveyor. During this process, a large amount of dust is generated, and the concentration is very high. Under the action of the airflow, the dust source will spread to the surrounding. , causing serious dust pollution.

2. Causes of dust production at the feed inlet

The ultra-fine mill is not a fully enclosed device. During the feeding process, dust overflow will inevitably occur, resulting in a relatively high concentration of dust around the feed port.

3. Causes of dust production at the discharge port

ultrafine mill

After grinding, the stone needs to enter the conveyor through the discharge port. Due to a certain drop between the feed port and the discharge port, a part of the stone will flow into the air. At the same time, during the movement, the stone powder is also It will then rise and spread to the surroundings.

In order to effectively solve the problem of ultra-fine mill dust, it is necessary not only to optimize and improve the local structure of the equipment, but also to control the dust source with a certain external force to avoid further diffusion of dust. A sealing cover is arranged at the source of the dust, and a water spray and a dust suction device are arranged at the same time.
