The needle bar mill uses a needle disc with the opposite direction of rotation, and the final needle bar speed exceeds 200 m/s, which can depolymerize and disperse or grind the soft to medium hardness raw materials into ultra-fine powder.
The needle bar mill can also be used for the coating modification of stearic acid-coated ultrafine fillers.
Equipment technical characteristics
Fineness can be as low as 5 µm
Suitable for crushing, disintegrating, spheroidizing and shaping of various powders with Mohs hardness below 3;
The rotor can be adjusted at a variable speed, and products of different fineness have been obtained.
It can carry out high-efficiency low-temperature freezing and crushing.
The crushing force can be optimized by changing different crushing devices to obtain the highest efficiency.
Simple operation, easy to disassemble and clean.
Multi-purpose design: can be used in series with classifiers, vibrating screens, etc., suitable for centralized particle size distribution and ultra-fine requirements;
※Explosion-proof, air-cooled, heating design: nitrogen protection cycle technology to ensure continuous and stable operation of easily oxidized hazardous materials;
working principle
The material is quantitatively input into the crushing chamber through the adjustable feeder to ensure the uniformity and continuity of the feeding process. The material rotates at high speed in the crushing chamber with the airflow. During the rotation, it is crushed instantly by the superimposed impact of multiple crushing forces such as friction, shear, and collision. The crushed material enters the cyclone separator and is discharged by the gravity of the rotary centrifugal fan, and the dust enters the pulse dust collector, and is collected after filtering and dust removal. The fineness of crushing is achieved by changing the screen adjustment or multiple crushing devices. The whole machine can be designed according to GMP standard, all made of stainless steel, which belongs to dust-free crushing.
Application field
Food, medicine, chemicals, pigments, pigments, fillers and coating modification, etc.
