Needle disc mill

Needle disc mill and nail disc mill are a fine impact crusher with one or two rotating discs driven by high-speed explosion-proof motors, which are covered with nail shaped pins. The relative speed of the outer edge pins on the rotating disc can reach 250 m/s. The nail plate mill achieves the goal of ultrafine crushing by striking the material without damaging the crystal form of the material. The rotating disc grinding component of the nail disc mill has various forms to choose from, and the fineness can be adjusted by changing the needle disc speed, so it can flexibly handle the requirements of various raw materials and product fineness. In the production of cell culture media, needle disc mills are often used as grinding components to produce ultra-fine and uniform powder products. The particle size control range of the powder is 10um-200um, and the particle size range is adjustable.

Product Description

The working principle of the hammer mill is that the material enters the crushing bin, and the powder is impacted by the high-speed rotating grinding knife, mainly by the impact effect to crush the material. The material enters the hammer mill and is crushed by the impact of the high-speed rotating hammer head. The crushed material obtains kinetic energy from the hammer head of the hammer mill and rushes to the baffle and screen bar in the frame body from the high-speed. At the same time, the materials collide with each other and are crushed many times. The materials smaller than the gap of the screen bar are discharged from the gap. Some larger materials are impacted and ground by the hammer again on the screen bar, extruded and crushed, the material is squeezed out of the gap by the hammer head of the hammer breaker to obtain the product of the required particle size. The feed inlet is equipped with a star-shaped blanking valve to control the blanking speed and prevent dust from being generated during the crushing process.
