Lead: The universal grinder uses the high-speed relative motion seen by the movable toothed disc and the fixed toothed disc to make the pulverized material get crushed by the combined action of tooth impact, friction and material impact.
Material from the hopper through the dithering device into the crushing chamber, centrifugal force generated by the high-speed rotation of the movable tooth plate is thrown from the center to the chamber wall, impact, shear, grinding and the steel teeth between the movable tooth plate and the fixed tooth plate. The impact between the materials is crushed, and the final material reaches the annular space on the outer wall of the turntable. The fine particles are discharged from the bottom through the contour sieve plate, and the coarse powder is repeatedly crushed in the machine.
Universal crusher mainly has the following characteristics:
1. High output, low noise, low energy consumption, simple maintenance, easy installation, etc.;
2. The gap between the rotor and the stator is accurate and the crushing effect is the best;
3, good sealing performance, built-in labyrinth seals, O-ring sealing machine door, to prevent dust escape;
4, due to the high-speed rotation of the rotor, brings in a lot of air, so there is a self-cooling function, can be applied to require lower heat-sensitive material crushed;
5, system pipe connection using quick release structure, quick and easy disassembly, cleaning;
6, can be equipped with cyclone separator and dust collector, no dust during the production process, dust traps can effectively trap the micro-powder in the air. At the same time, fine powder trapped by dust traps can be effectively recovered, reducing the material loss rate.
Solenoid valve is an industrial equipment controlled by electromagnetism. It is an automatic basic component used to control fluid. It belongs to actuator. Pneumatic solenoid valve is one of them. It blocks or leaks different oil drain holes by controlling the movement of valve body. The oil inlet hole is normally open, and hydraulic oil will enter different oil drain pipes, Then the oil pressure of the pneumatic solenoid valve pushes the piston of the oil cylinder. In this way, the mechanical movement of the whole solenoid valve is controlled by controlling the current of the electromagnet of the pneumatic solenoid valve.
Characteristic
It can work normally under vacuum, negative pressure and zero pressure, but its diameter is generally less than 25 mm.
It can also operate under zero pressure difference, vacuum and high pressure, but it has high power and must be installed horizontally.
The upper limit of fluid pressure range is high, which can be installed arbitrarily (need to be customized), but the condition of fluid pressure difference must be met.
Principle editing voice
There is a closed cavity in the pneumatic solenoid valve, and there are through holes in different positions. Each hole of the pneumatic solenoid valve leads to different gas pipes. There is a valve in the middle of the cavity and two electromagnets on both sides. The valve body will be attracted to which side when the magnet coil is electrified;
The pneumatic solenoid valve blocks or leaks different exhaust holes by controlling the movement of the valve body, and the air inlet is normally open. High pressure gas will enter different exhaust pipes, and then push the piston of the cylinder through the air pressure of the pneumatic solenoid valve. In this way, the mechanical movement of the whole solenoid valve is controlled by controlling the current of the electromagnet of the pneumatic solenoid valve.
Operation principle of pneumatic solenoid valve
We said the pneumatic solenoid valve working position (solenoid valve on or off), in fact, refers to the pneumatic solenoid valve spool position.
