Crushing technology has been generally concerned as a new type of food processing method. Company, as a manufacturer of superfine pulverizer, today, today, come to introduce the classification, working principle and characteristics of airflow pulverizer. 1. Virtual flow pulverizer gas flow pulverizer is also known as fluid milling or jet mill, the working principle is to generate high pressure using compressed air or overheating vapor, which causes ultrasonic air flow through nozzles to impact, collide, and rub. The purpose of ultrafine comminution (grasping the particles material is grinded into the particle diameter micron stage).
The spray air flow grinding is a device that is smashing from two or more directions to each other from two or more directions using a pair or several or several or several or several or more directions. Due to the direct collision of the material, the impact strength (Strength) is high, the energy utilization is high, and can be used to crush Mohnes 9.5 or less, brittle, toughness, and the product particle size can reach 0.0750 mm.
And the product is smashed very fine, and the particle size distribution range is narrower. The ultrafine pulverizer utilizes air separation, heavy polishing, and shear, the ultrafine manner is used to achieve a dry material ultrafine pulverized apparatus. It consists of a cylindrical crushed chamber, a polishing wheel, a polishing rail, a fan, a material collection system, and the like.
The material enters the cylindrical pulverizing chamber by the feed opening, and is crushed by the polishing wheel that is circumferential movement along the grinding rail, and dissensibly. Further, since the gas is expanded at the nozzle, the pulverization process is not accompanied by heat (Heat) while overcoming the target grinding target plate and the cycle of the cycle, which is easy to wear (a basic type of component failure. Features, reducing pollution to the product, increasing the use cycle. 2. The working principle of ultrasonic airflow pulverizer is to introduce purified dry compressed air into a special design nozzle, forming a supersonic gas flow above 2.5 Mach, and enters the crushing chamber through several phased nozzles, and the material particles who want to smash first.
The gas-solid mixing stream is mixed with compressed air, and then inserted into the pulverizing chamber in the supersonic manner, impact on the intersection of the jet, a strong impact, collision and friction, etc., the interaction is pulverized, and then pass through eddy currents Profile: Fuko current) High-speed classifier, powder is fractionated by different granularity, the radial movement speed is graded, and the particle size should be metThe ultra-fine particles are separated from the whirlwind, and the coarsequamage is re-entered into the pulverized chamber with the newly added gas-solid mixing stream. The above pulverization process. The characteristics of supersonic air flow pulverity are mainly reflected in:
(1) no pollution. The ultrafine pulverizer Zky series can be widely used in the ultrafine comminution demand for traditional Chinese medicine, western medicine, pesticide, biological, cosmetics, food, feed, chemical, chemical, ceramics. Especially for fibrotic, high toughness, such as Cordyceps, tea, Ganoderma lucidum, etc. is more perfect. Due to the use of air, the entire process is carried out in a sealed state, and it will not cause pollution as long as the air is purified.
(2) Low temperature. Since the sharp expansion of the compressed air is a heat-insulating process, the entire pulverization process is in a low temperature environment, and the pulverization of the material is completely completed at low temperatures, suitable for thermal material pulverization.
(3) Physical. The airflow is purely pure, which does not have any chemical reaction, and maintains the original chemical properties of materials.
(4) High precision (accuracy). The ultrafine pulverizer utilizes air separation, heavy polishing, and shear, the ultrafine manner is used to achieve a dry material ultrafine pulverized apparatus.
It consists of a cylindrical crushed chamber, a polishing wheel, a polishing rail, a fan, a material collection system, and the like. The material enters the cylindrical pulverizing chamber by the feed opening, and is crushed by the polishing wheel that is circumferential movement along the grinding rail, and dissensibly. Powder is distributed narrow and uniform (jūn yún), which is strictly limited to large particles and avoids excessive crushing.
