Advantages of ultra-fine jet mill

Ultra-fine jet mill is a kind of equipment for producing ultra-fine powder. It is the equipment with smaller fineness on the market at present. It is suitable for building materials, chemicals, fillers, plastics, papermaking, coatings and other industries.

After the large block material is crushed to the required particle size by the hammer crusher, it is sent to the silo of the ultra-fine jet mill by the elevator, and fed into the main machine evenly and continuously through the feeding equipment. Under the action of centrifugal force, the material is scattered around from the bulk material disc and falls into the grinding chamber, where it is impacted, rolled and ground by the grinding rollers. Ultra-fine grinder has the following characteristics.

  1. High production efficiency

The new design of the grinding roller grinding ring improves the grinding efficiency. The results show that when the particle size and power of the finished product are the same, the efficiency of the stirring mill is increased by 40%, which is more than double the output of the ball mill, but the energy consumption of the system is only 30% of the airflow consumption.

  1. Low operating cost

Grinding rollers and grinding rings are forged with special materials, which improves the utilization rate. Compared with impact grinder and eddy current grinder, the finished product has the same fineness, and the service life of vulnerable parts is extended by 2-3 times. When processing calcium carbonate and calcite, the service life can reach 2-5 years.

  1. The product is in good condition

The cage type powder separator effectively improves the powder selection accuracy, and can configure the multi-cage powder separator according to the user’s requirements such as output, fineness, and sieving rate. The product fineness can be adjusted arbitrarily between 325 meshes and 2500 meshes, and the single product fineness can reach d97≤5 microns.

  1. Continuous production process

Since there is no movable bearing and no screw in the grinding chamber, there is no problem that the bearing and its seal are easily damaged, and there is no problem that the screw is easy to loosen and damage the machine. It is externally lubricated with the main shaft, which can realize non-stop lubrication in the external machine, and non-stop production for 24 hours.

  1. Wide range of application

It can be widely used for grinding more than 100 kinds of materials such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, mica, graphite, fluorite, phosphate rock, potassium ore, pumice and so on. In addition, according to materials, output, fineness and other aspects, combined with industry experience, multi-scheme configuration can be carried out to meet the needs.

  1. Clean and environmentally friendly

Using high-efficiency pulse dust collector, the complete set of equipment has no dust pollution, and is equipped with silencing device and anechoic chamber to reduce environmental noise.
