What are the difference in the airflow pulverizer and the mechanical crusher? Hold
Industry analysts said that with the advancement of scientific and technological progress, manufacturing process improvement, my country's market on micro-powder and ultrafine powder is continuously improved, and the importance of gas flow grinding is increasingly prominent. The downstream application is constantly Expansion, the industry has a good prospect. At the same time, the application of high-performance materials and new materials has also made my country's market automation, intelligence, and high precision requirements in China, and upgrades to high-tech content to the inevitable trend of my country's gas flow grinding industry.As an ultrafine pulverized device, the airflow pulverizer has very high evaluation in the user. However, it is also known as a mechanical pulverizer for ultrafine pulverized equipment, and there is also a high application rate in many fields, then what is the difference between these two devices? What are the specific performance? The following is a domestic super-smashing machine source manufacturer-Shandong Erfai Powder Technology Co., Ltd. Xiaobian introduced it.
First, the pulverization mechanism of the airflow pulverizer and the mechanical crusher is different. The airflow pulverizer is to achieve huge kinetic energy by using the material under high-speed airflow, causing a crushing indoor material particles. High-speed collisions and severe friction, and high-speed airflow shearing materials, thereby achieving the purpose of crushing materials. The mechanical pulverizer is a violent impact using a rotating body (holding, hammer, plate, etc.) rotating around the horizontal or vertical axis, so that it is impact collision with the fixed body collision or particles, thereby reaching the powder. . The difference between airflow pulverizer and mechanical crusher is mainly reflected in the following points:
1. Years
Our airflow pulverizer allows the material to accelerate the consistent crushing strength by establishing a uniform smash field The particles of the material were quickly separated by a collision, and the time of the material stayed in the pulverized cavity was extremely short, thereby avoiding the overstrain of the product, improving the yield. When producing 40-120 mesh (+ 40≤25%, - 120 mesh ≤10%), the yield is not less than 87%; 40-325 mesh (+ 40 ≤ 1%, - 325 ≤ 1%) When the product, the product rate is not less than 85%. Other mechanical crushing cannot establish a uniform pulverization field, the particles have collided with multiple collisions, and the eligible particles in the afterbrafting, resulting in pulverization, thereby increasing the content of fine powder, and the product rate is relatively low. andThe adjustment means of the mechanical pulverizer is rare, generally only controlling the pulverization effort by adjusting the rotational speed of the mill, there is a certain limitation, the equipment is easy to worn, and the particle size distribution of the product and the impact rate have great effect.
2. Screening
Our company's airflow pulverizer has a high-efficiency turbine classifier. After the material is pulverized, the fine powder is selected by the turbine grace machine, and the finished product and the thick particles are sieved, so that the material is extremely easy The screening, not only greatly improves the screening efficiency, extending the service life of the screen, but also ensures the screening rate of the material, and because the fine powder content in the sie is small, the fine powder in the screen is flying, producing Environmental cleaning. The particles of the mechanical pulverized machine are mixed into mixed particles. The thick powder is mixed together, and the fine powder is easily adhered to the crude particles when screening, and the residence time of the material is long, The wear of the screen is large, the screening efficiency is relatively low, and the dust is large during the screening process. And more ultrafine powder adheres to qualified particles, will have a certain impact on product quality.
3. Equipment wear and maintenance rate
Our airflow pulverization unit is a gas flow to make crushing power, equipment itself has no rotation parts, greatly prolongs the service life of the host crushing part, company-shaped MQW metal silicon special airflow The pulverizer has been used through our company's customers for nearly two years, and has not been replaced. The main crushing equipment is very small, and the equipment can be stable, and the product quality is stable. The main susceptible parts of the airflow pulverizer are the grading wheel of the turbine classifier, the service life is more than 1,500 tons, the replacement is convenient, and the time is short.
The mechanical pulverizer is a medium to impact / roller, rolled in a medium, which is high, and has a sharp corner shape, and the solid to the equipment is quite large. General 3-5 Days need maintenance to replace spare parts, the equipment maintenance work is large, the cost of the loss is high, and when the replacement is time, it affects the production.
4. Difference of product purity
The gas flow pulverizer is pulverizing the material using airflow, the equipment is small, and the wear-resistant part is used, so the product is purity, no need magnetic Choose pickled. The mechanical pulverizer is a medium (hammer head) high-speed, the material impact is pulverized, the equipment wear is large, and the impurities of wear are naturally brought into the product, causing the contamination of the product, the iron content is increased.
5. Differences for the topography
I amThe product particle size distribution of the driver's gas flow pulverizer is evenly distributed, and the surface is a honeycomb in the electron microscope, the specific surface area is large, and the ultrafine powder adhesive on the finished particles is very small, which is conducive to the production of the lower process . The particle size distribution of the mechanical pulverizer is uneven, the phenomenon of segmentation, the particles are tabulated / strip, the surface is too smooth, the specific surface area is small, and since there is no airflow classification device, the particle surface adheres to ultrafine powder, There is a certain impact on product quality.
6. Differences of the production environment
Our company's airflow milling unit complete system is full-negative pressure, equipment adopts the most advanced division-off pulse dust collector, no dust, production environment, clean production environment, no fine Powder loss. Dust and dust during the production of mechanical crushers, the production environment is extremely poor, and the silicon powder is large.
The above is the difference between the airflow crusher and the mechanical crusher listed by Shandong El Pie. Do you have any understanding? Shandong Erpa is a source of domestic airflow pulverizer, specializing in the production of gas flow crusher, airflow grading machine, mechanical impact mill, inert gas protection pulverization unit, and free processed experiments and testing.
