Basic introduction to plastic shredders overview of the relevant theories percussive smash smash, studied the mechanism at room temperature plastic shredders crushing ordinary plastic recycling. Studied experimentally by plastic crushing speed, impact feed size, feed rate and the discharge port location and other parameters of plastic crushing effect. According to its structural properties and plastic powders description, combining features of the mill powder collision of high frequency, high-speed, high stress, high strain rate, the proposed new ideas for this part of the crushing effect of brittle fracture. Crushed plastic shredders plastic material in the injection molding machine or granulator production of raw materials at the same time, resulting in defective products and outlet material can be promptly put into the machine side plastic shredders. Operation note 1, plastic shredders and power units to be installed securely. If you need long-term fixed plastic crusher operation, it should be fixed on the basis of the cement; if you need plastic crusher mobile operations, the unit should be installed in the machine is made with the angle iron base, and to ensure the power machine (diesel or electric motor) and plastic crusher pulley groove in the same plane of rotation. 2, plastic shredders after installation to check ministries fastening fasteners, if loose to give to be tightened. At the same time you want to check the belt tension is appropriate. 3, before the start of plastic shredders, rotating the rotor by hand, check the tooth claw hammer and rotor operation is flexible and reliable, whether the collision phenomenon broken interior, the direction of rotation of the rotor is consistent with the direction of the arrow machine, power machine and plastic crusher lubrication is good. 4, it should not replace the pulley, the speed is too high resulting in crushing chamber to prevent an explosion, or the speed is too low affects the efficiency of the mill. 5, plastic shredders should be kept after starting its first idling 2 ~ 3min, no abnormal phenomenon feeding after work. Practice General Provisions Article 1 loader, grinder drivers must be trained to achieve "three know" (to understand the structure, to understand the performance, understand the principle), "Four" (uses, maintains, would be maintained, it will deal with failure ), trained examination, after obtaining the certificate, shall be allowed to operate posts. The first two drivers with the face conveyor, belt conveyor lane closely with transport drivers, unified signal contact, in order to open, was closed. There are a large lump, when gangue crusher inlet in the accumulation of spills, should stop working and surface scraper conveyor operation. If the big lump, gangue not enter break transfer or metal objects, must stop processing. An examination and treatment, the various parts of the motor, reducer, hydraulic couplings, nose, tail and other couplings must be complete, intact, tight. Reducer, hydraulic shaft section should be no oil leakage, oil spills, oil should be appropriate. 2, the signal must be sensitive and reliable, no signal is allowed to boot. To ensure the integrity of the spray sprinklers. 3, power cables, operating lines must hang neatly, no squeezed phenomenon; 4, near the head of coal, waste rock, debris and motor, reducer must be swept clean of coal dust; 5, Face shaving head and conveyor loader to the right tail of the lap; 6, scraper chain plate crucial moderate, scraper and tighten the screws must be complete; 7, loader trolley must be stable and reliable; 8, the next part of the deck loader boot situation, Peter functioning ministries should be no abnormal sound, scraper, chains, connecting ring should be no torsion twist, twist twist, bending; 9, shredders, shredder at the roadway must be intact and firm. 10, a safety net and protection devices grinder, deformation does not fail to ensure safe and reliable; 11, loader, roadway must be intact at the mill, firmly.
