If the shaft wears little, just to repair its geometry, it can be turned on the lathe to bring the journal to the correct geometry and then reduce the bearing inner diameter accordingly. However, after several such treatments, if the journal size is reduced by 5% compared to the original, no turning is allowed, and the new shaft should be replaced.
The machine is provided with such functions as automatic lifting, mixing, lowering, etc. A bin mixer and variety mixing bin of different specifications ,it can meet the mixing requirements of different batches and diversified varieties of products. It is an ideal machine for mixing in pharmaceutical plants. It is also widely used in such industries as medicine, chemical industry, food, etc.
Features:
â—This machine is a new model that our company has extensively absorbed and digested foreign advanced technology, successfully developed in combination with national conditions. Reasonable structure, stable performance, convenient operation, no dead corners, and no exposed bolts.
â—The rotating body (mixing bin) symmetry plane is at an angle of 30°to the rotation axis. The materials in the mixing bin rotate along with the rotating body and make tangential movement along the hopper walls, producing strong turning and high-speed tangential movement and achieving the best mixing effect.
â—It adopts PLC automatic control . It is provided with the infrared safety device and the discharging butterfly valve with the misoperation preventer to ensure safe production.
â—One machine can be equipped with bins of various specifications and quantities.
â—The machine effectively controls dust pollution and cross contamination, reduces loss of materials, controls material layering, optimizes production processes.
â—Meet GMP requirements.
Working Principle:
The machine is composed of two machine bases, rotation frame, rotation system, lifting system, control system, etc. Push the mixing bin into the rotation frame and complete the positioning. Start the control system to lift the rotation frame to the mixing height and clamp it reliably. The driving system will carry out automatic mixing according to the set time, rotation speed and other data. After the mixing operation is finished, the rotation frame will stop vertically, the bin will automatically fall to the ground, the machine will stop and process data will be printed. The bin is transferred to the next procedure.

When the thrust plate is seriously worn or the front thrust plate is broken, the ore in the crushing chamber must be removed, the worn or broken thrust plate must be taken out, and the brake plates on the moving jaw and the connecting rod should be inspected for damage. Then pull the moving jaw near the fixed jaw, lubricate the working surface of the bracket with dry oil, replace it with a new thrust plate, make it slowly contact with the working surface of the bracket, and tighten the horizontal lever to make the thrust plate Clamp, tighten the safety cover, connect the lubrication system, and then adjust the size of the discharge port.
To what extent is the jaw crusher shaft, eccentric shaft and bearing bush worn?
