What is a Pulverizer?

A pulverizer is a machine that pulverizes large-size solid raw materials to a required size. The crusher is composed of coarse crushing, fine crushing, wind conveying and other devices, and achieves the purpose of the crusher in the form of high-speed impact. Wind energy is used to make powder at one time, eliminating the traditional screening process. Mainly used in mining, building materials and other industries.

A pulverizer is a machine that pulverizes large-size solid raw materials to a required size.

Crushers can be divided into coarse crushers, crushers, and ultrafine crushers according to the size of the material being crushed or crushed.

The external force applied to the solid during the crushing process is

According to the D90 standard of the required material fineness (90% of the material reaches the predetermined fineness), the crusher can be divided into a crusher (below 60 mesh), a crusher (60-120 mesh), and an ultra-fine crusher (120-300 Mesh), ultra-fine crusher (above 300 mesh).

The external force applied to the material during the crushing process is rolling,

Large pulverizers (equipment with higher output on the premise of the same pulverization fineness) are mainly applicable to the pulverization of mineral materials in metallurgy, building materials, chemicals, mining, highway construction, water conservancy and hydropower, refractory materials, steel and other industries.

Third, the structure principle

Inside the machine, a smashing rotor consisting of four sets of cutter heads and a total of 56 blades is supported on the bearing seats of the left and right end covers for high-speed rotation, so that solid material particles are squeezed between the toothed lining in the inner cavity and the blade. Various mechanisms such as tearing, collision and shearing can achieve the crushing purpose. At the same time, the high-speed rotation of the large and small impellers at both ends of the rotor, through the cavity form vortex effect between the inlet and the outlet, allows the crushed particles to be smoothly imported ( Large gap) to (small gap) to achieve crushing and refinement. In order to limit the temperature in the cavity to be too high, to improve the crushing efficiency, to prevent particles from sticking to the cavity, sticking the knife, blocking the teeth, and agglomeration, 4 sets of wide cavity water jackets on the surface of the cavity are forced to cool the water, so that the temperature in the cavity is controlled to be low limit.

Third, the working principle

The material is sent into the crushing chamber by the feeding hopper. After the impact of the blade and the knife seat, the rotary knife and the fixed knife are sheared and crushed at the same time. Due to the effect of rotary centrifugal force, the material automatically flows to the outlet.

Development market

Due to the widespread use of shredders in various industries, the research and development of shredders at home and abroad have attached great importance. The ACM type pulverizer developed by Japan's Hosokawa company is a typical vertical-shaft classification micro-pulverizer.

Pulverizer to fill the technological gap in China and the world.

Direction of development

The overall development trend of non-metallic mineral raw materials or materials in the future is high purity, ultra-fine and functional. Comprehensively develop and utilize various non-metallic minerals by using high-purity ultra-fine non-metallic mineral deep-processing raw materials as a leader. Although high-purity and ultra-fine powder can be prepared by chemical synthesis, the cost is too high and it has not been used for industrial production. The main method to obtain ultra-fine powder is still mechanical pulverization. The difficulty of making ultra-fine pulverization and classification technology relying on mechanical methods to increase ultra-fine powder is increasing, and its research depth is endless. The ultra-fine crushing technology is a combination of multiple technologies, and its development also depends on the advancement of related technologies, such as the processing of high-hardness and high-toughness wear-resistant components, high-speed bearings, and determination of particle size distribution of sub-micron particles. Therefore, the development of ultra-fine crushing technology should focus on the following aspects.

(1) Develop fine classification equipment and other supporting equipment that are matched with ultra-fine crushing equipment. The closed-circuit process combining ultra-fine crushing and classification equipment can improve production efficiency, reduce energy consumption, and ensure qualified product particle size. It can be said that large processing capacity and high-precision classification equipment are the key to the development of ultra-fine crushing technology. Research and development should be carried out from the perspective of the entire process system, and other auxiliary process equipment such as classification equipment, product transport equipment, etc. should be improved, matched and perfected on the basis of the existing crushing equipment.

(2) Improve efficiency, reduce energy consumption, and continuously improve and improve ultra-fine crushing equipment. The key to ultra-fine crushing technology is equipment. Therefore, we must first develop new ultra-fine crushing equipment and its corresponding classification equipment, the latter seems more urgent. Grinding aids and surface-active dispersants will be used in the ultra-fine grinding process.

(3) Integration of equipment and process research and development. The ultrafine crushing and classifying equipment must be adapted to specific material characteristics and product indicators, and the specifications and models are diversified. There is no ultrafine crushing and classifying equipment that is efficient and versatile for any material.

(4) Develop multifunctional ultra-fine crushing and surface modification equipment. The combination of ultra-fine crushing and drying processes, the combination of ultra-fine crushing and surface modification, and the combination of mechanochemical principles and ultra-fine crushing technology can expand the application range of ultra-fine crushing technology. With the help of surface coating and solid-state miscibility, some new materials with unique properties can be prepared.

(5) Development and research of particle size detection and control technology related to ultrafine crushing technology. The particle size detection and control technology of ultrafine crushing is one of the important conditions to realize the industrial continuous production of ultrafine powder. Particle size testing instruments and measurement control technology are closely related to ultra-fine crushing technology, and must be jointly tackled with experts in these fields.

Ultrafine crushing is advancing towards the nanometer level, and the dispersion and evaluation of the related low-contamination and wear-resistant materials and nanometer powders will become a huge technical obstacle, and research in this area will be valued.

Modern engineering technology will require more and more high-purity ultra-fine powders. Ultra-fine crushing technology will play an increasingly important role in high-tech research and development. The high-tech industry is closely related to non-metallic minerals. In the future development of non-metallic mineral deep-processing technology and industrial development, the development of high-tech and its industries must be considered; modern non-metal deep-processing technology and traditional industrial processing technology penetrate into each other, and their development must Consider the technological transformation and progress of traditional industries; in order to make better use of limited non-metallic mineral resources, comprehensive utilization must be considered.
