Airflow pulverizer is one of the "artifacts" of non-metallic mineral ultrafine


  Small laboratory gas flow grinding, laboratory equipment, small gas flow grinding, laboratory airflow classifier, for various laboratory requirements, special airflow pulverization unit for manufacturing production. The product has: full-negative pressure design, high pulverized grading accuracy, uniform particle size distribution, small land and other features. It can be widely used in various experiments such as colleges, pharmaceuticals, and materials.Non-metallic minerals (such as quartz, kaolin, calcium carbonate, bentonite, silicahydrate, heavy crystal stone, mica, etc.), their hardness, strength, ductility, etc. It is generally harder, brittle, and thus its pulverized refinement (0.5-10 μm) process also has its own characteristics, and has a high requirements for particles, purity and granular shape.

  Currently, ultra-fine pulverization equipment commonly used in my country's non-metallic mine industry mainly has airflow mill, mechanical impact ultrafine pulverizer, ball mill, stirring, sand mill, vibration grinding Wait. Different kinds of crushing equipment adapted to minerals of different attributes, with specific correspondence of hardness, raw material particle size, humidity, yield, etc., and different operational parameters of the same equipment have a decisive effect on the characteristics of the product. Today, Xiaobian will first say the airflow crusher.

  Airflow pulverizing equipment is to form a high-speed flow field using high pressure air, inert gas or superheated steam expansion and cooling, and the material particles collide with each other, friction, shear to achieve material detail, can be divided into Flat airflow pulverizer, fluidized bed airflow pulverizer, circulating tube airflow pulverizer, spray gas flow pulverizer, target airflow pulverizer, etc. The kinetic energy source of material particles in the airflow pulverizer is a compressed gas, and when the high pressure gas is accelerated in the sloring pipe, the pressure is converted to the kinetic energy of the material particles. When the particle size of the material is uneven, the particle speed of the mass is fast, the mass is slow, and the particle diameter is collided under the action of the speed difference, so that the particle size is homogenized; when the particle size is more uniform At the time, the high-speed jet is a typical turbulence, and its flow is uniform as uniform, and there is a dramatic momentum blend in the mainstream tract direction, and the material particles collide, friction, and friction under the blending flow. Get a more uniform refinement particles.

  Airflow Crushing Process

  Overall, high-speed airflow expansion and cooling, even if friction produces a certain amount of heatIt will also be taken away by the airflow that is continuously entered, so that the temperature in the flow field is low, which makes the airflow comminution particularly suitable for processing thermal materials. The speed field of high-speed turbulence is more full, so the gas flow is also relatively uniform, and the particle size distribution of the particles is narrow, and the granular shape is also ideal.

  Airflow pulverizer is one of the most common ultra-fine pulverized equipment, widely used in talc, kaolin, heavy crystal stone, graphite, silicahydrate, zirconte and other non-metallic minerals and other brittle materials of other brittle materials or Smash, product fineness is generally 3-45 μm.

  For the next overseas expansion, the General Manager of AlPa Powder Science and Technology said that AlPa Powder Technology is very clear and full of confidence. In the future, AlPa Powder Technology adheres to innovation, quality, service, and constructs "global sales" system to form a global competitive manufacturing enterprise.
