Small laboratory airflow milling, high precision: the most exclusive D50 = 0.3 microns, and the accuracy can be controlled at the maximum particle size of no more than 3 microns. Small noise: The main operating components are imported components such as bearings, air blowers, etc., and air compressors such as needle. Small floor area: It is integrated on a platform for about 1 meter, no more than 2 meters, and installs the mandrel wheel, movable and fixed. Easy to operate, easy to disassemble, easy to clean.
Digitally have different performance and applicable ranges due to different manufacturers, which type airflow milling machine should be selected when the metal silicon should choose when commissioning? Through a large number of actual cases, the MQW gas flow pulverizer is more suitable for the processing of metal silicon, and below is introduced by Xiaobian.
The MQW airflow pulverizer is the machining requirements of Shandong Erpai, for the processing requirements of metal silicon (thick product particle size, high yield requirements), and develop a new special crushing equipment.
The company developed metal silicon powder special production line [metal silicon powder special airflow pulverizer] mainly has high yield, large yield, low equipment wear, low equipment maintenance rate, high product purity, clean product environment, clean production environment clean.
Metal silicon with MQW airflow pulverizer equipment advantage comparison
1. The yield
Our airflow pulverizer allows the material to accelerate the consistent crush strength by establishing a uniform smash field, and the material is qualified for one collision. The particles are quickly separated; the amount of time for the material stay in the pulverizing chamber is extremely short, thereby effectively avoiding the overstrain of the product, and improves 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. And the adjustment means of mechanical grinding is rare, generally only controlling the pulverization force by adjusting the rotational speed of the mill, there is a certain limitation, the equipment is easy to wear, and the particle size distribution rate of the product and the impact rate is great.
2. Screening
Our company's airflow pulverizer has a high-efficiency turbine classifier. After the material is pulverized, the fine powder is selected from the turbine grace machine, and the finished product and the crude particles are screened, so that the material is extremely easy to sieve, not only greatly improves screening efficiency Extend the service life of the screen, and ensure the screening rate of the material, and because the fine powder content in the sie is small, the fine powder in the screen is avoided, the production environment is clean. Mechanical mill is pulverized The particles are mixed particle size, and the coarse powder is mixed together. When the screen is sieved, the fine powder is easily adhered to the crude particles, it is not easy to sieve, the residence time of the material on the screen is long, the wear of the screen is large, screening efficiency Relatively low, the dust is large during screening. 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.
Mechanical grinding is a medium to shock / roller, rolled in a medium, which is high in metal silicon, and has a sharp corner, and the solid-pair of equipment is quite large, general 3-5 days. It is necessary to repair the spare parts, the equipment maintenance work is large, the cost of the loss is high, and the time is expensive, affecting 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. Mechanical grinding is made of a medium (hammer head) high-speed, the material impact is pulverized, the equipment wear is large, and the impurities that wear will naturally be brought into the product, resulting in the contamination of the product, the iron content is increased.
5. Difference of the topography
The particle size distribution of the product produced by our airflow milling machine is evenly distributed, and the surface is a honeycomb in electrical microscope, larger surface area, and finished particles adhere The ultrafine powder is extremely small, which is conducive to the production of the lower process. The particle size distribution of mechanical grinding is uneven,The phenomenon of paragraph file, the particles are tabulated / strip, the surface is too smooth, small specific surface area, and because there is no airflow classification device, ultrafine powder is adhered to the surface of the product, which has a certain impact on the 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 mechanical grinding process, the production environment is extremely poor, and the silicon powder is large.
Through the above, it can be seen that the MQW airflow pulverizer has highlighted advantages in the processing of metal silicon and has a large development potential. In addition, the MQW airflow pulverizer is also used in chemical, minerals, metallurgy, abrasives, ceramics, refractory materials, pharmaceuticals, pesticides, food, health products, new materials and other industries, and excellent effects, which are favored by users. . As a typical representative of the industrial powder equipment industry, ALPA Powder Technology With excellent products and services, the sales network covers more than 100 countries and regions around the world, and it is a powder equipment manufacturing.
