The full protective ceramic liner airflow pulverization charter has the following performance advantages: dry pulverization of various materials suitable for the Moh's hardness 9 or less, is particularly suitable for high hardness, high purity, and high value-added materials. The breakthrough of particle acceleration technology has greatly improved pulverization efficiency, reduced energy consumption, small pulverization, good particle shape, and no large particle size and no large particles, and the product particle size D97 = 3-74 microns were arbitrarily adjusted. During the pulverization, due to the sharp expansion of the airflow, the airflow temperature is lowered, especially suitable for the heat sensitive, low melting point and the volatile material. The material collides with each other, which is different from mechanical pulverization relies on the impact of the material or a hammer, and plus all-round ceramic liner, so the equipment is small, and the product is purity. It can be used in series with multi-stage airflow classifiers, and products producing multiple particle size sections at a time. The ceramic liner is pulverized, the equipment is compact, the disassembly and cleaning is convenient, and the inner wall is smooth without dead angles. The entire system is fully negatively pressed, no dust, low noise, clean environmental protection.
Everyone knows that when the mechanical equipment is processed, it will generally cause heat between the equipment components, the contact between the raw materials and the equipment, causing the temperature to rise, then for some thermal raw materials. Say, how to control the temperature during machining, is the weight. Especially when the pulverization is performed, it is the most easily warming process, how can the temperature constant increase? At this time, you need to use the airflow pulverizer. The airflow pulverizer is a representative product in ultrafine pulverizing equipment, both in processing fineness, efficiency has a very prominent manifestation, but it is not a highlight of the airflow milling. Let's take a look at the airflow. How does the machine do not warm up?
The source of kinetic energy 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.
Overall, the high-speed airflow expansion and cooling, even if the friction produces a certain amount of heat, it will be taken away by the airflow that is continuously entered, so that the temperature in the flow field is low, which makes the airflow pulverized 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.
