Vertical spinning dive pulverizer

Abstract

The invention relates to a vertical plunger pulverizer. A rotary main shaft of the pulverizer is vertically placed, a pulverizing chamber is divided into a grade-one pulverizing chamber and a grade-two pulverizing chamber that can pulverize soft and hard components of the materials respectively, which is more thoroughly pulverized than the existing technologies, thus reducing the pulverizing times due to re-pulverizing the oversized particles, saving time and improving the production ability of the machine. A hard abrasion resistant materials in an imbedded scaleboard of a shell can further improve the service life and security and stability of the machine; the size of particles can be adjusted according to different requirements; the invention is operated in a negative pressure, which effectively control the overflowing of the nanoids, and beneficial to environmental protection and generate small noise during the process.

Description

technical field [0001] The invention relates to a powder making device, in particular to a vertical gyratory pulverizer which crushes solid materials by gyrating. Background technique [0002] The crushing device of solid material plays a very wide role in our daily life and work. People have carried out a lot of exploration on the crushing device of various solid materials, and proposed various grinding methods, such as rod milling method and ball milling method. , roller method, Raymond method, etc., due to the different physical properties of various solid materials, their effects are also very different. [0003] Limestone powder is widely used in desulfurization of coal-fired boilers, smelting furnaces, etc. In order to improve the desulfurization effect of limestone, various methods have been tried for crushing limestone. For example, Chinese patent 91100851.9 has announced a kind of ore pulverizing device, is to utilize the principle of electromagnetic suction to pul...

AI Technical Summary

Problems solved by technology

Although it can also play the role of crushing, its function is single, and it cannot be classified and transported outward at the same time as crushing. Because the raw materials are squeezed during the crushing process, the chemical activity is reduced.

And the fine powder cannot be effectively controlled in the production process, causing environmental pollution

[0005] The rotary pulverizer disclosed in Chinese patent 03210574.6 works in a horizontal manner and is divided into a crushing chamber, a grading chamber and a blowing chamber in a horizontal direction. It can be crushed, classified and discharged during its working process. It has complete functions and low cost. The energy consumption is small, but its service life is short, the production capacity is low, and it cannot meet the requirements of large quantities
