The Advantages Of Vertical Pulverizer Processing Coal Powder

2020-09-06

The vertical mill has a wide range of applications and large market demand, which is closely related to the performance of the vertical mill itself. The vertical pulverizer improves the efficiency, output, and particle size of the finished product in the production and processing, optimizes the disadvantages of the pulverizer, greatly increases the output, and saves energy and reduces consumption.wHXUltrafine Grinder, Ultrafine Mill For Sale

The Working Principle Of The Vertical Mill

The material to be ground is fed into the center of the rotating grinding disc by the air-locking feeding device. Under the action of centrifugal force, the material moves to the periphery of the grinding disc and enters the grinding roller table. It is crushed under the pressure of the roller. At the same time, the ground material is blown up by the high-speed airflow at the air ring to dry the suspended material, and the fine powder is brought into the separator by the hot air for classification. The qualified fine powder is collected by the dust collection equipment as a product, which is unqualified The coarse powder falls to the grinding plate and re-grinds. In this way, the whole process of grinding operation is completed, and the integrated operation of material crushing, drying, grinding and powder selection is realized. The vertical mill is mainly composed of a powder separator, a grinding roller device, a grinding disc device, a pressure device, a reducer, a motor, and a shell. The separator is a highly efficient and energy-saving powder selection device. The grinding roller is used to crush the material. The grinding disc is fixed on the output shaft of the reducer, where the grinding roller crushes the material. The pressure device is a component that provides grinding pressure to the grinding roller, and provides sufficient pressure to the grinding roller to crush the material.wHXUltrafine Grinder, Ultrafine Mill For Sale

The Advantages Of Vertical Mill

(1) The production investment cost is greatly reduced: the vertical mill system has simple process flow, compact layout, small building area, and covers an area of about 70% of the ball mill system, and the building space is about 60% of the ball mill system and can be deployed in the open air , Which directly reduces corporate investment costs. In addition, the vertical mill has a separator, so there is no need to add a powder separator and lifting equipment. The dust-containing gas from the grinding mill can be directly collected by a bag filter or an electric dust collector.wHXUltrafine Grinder, Ultrafine Mill For Sale

(2) High production efficiency, energy saving and environmental protection: The vertical mill adopts the principle of material layer grinding to grind materials, with low energy consumption, and the power consumption of the grinding system is 20% to 30% lower than that of the ball mill, and as the moisture of the raw material increases, The power saving effect is more obvious. Compared with ball mill system, the energy consumption of vertical mill system can save 30%-40%. The vertical mill does not have the metal impact sound of the steel balls colliding with each other and the liner in the ball mill, so the noise is low, which is 20-25dB lower than that of the ball mill. In addition, the vertical mill adopts a fully enclosed system, which works under negative pressure, without dust, and has a clean environment.wHXUltrafine Grinder, Ultrafine Mill For Sale

(3) Strong material drying ability: The vertical mill adopts hot air to transport materials, and can control the inlet air temperature when grinding materials with large moisture to make the product reach the required final moisture. It can be dried in the vertical mill—the material with the water content of 15%-20% is ground into the mill.wHXUltrafine Grinder, Ultrafine Mill For Sale
