|Universal grinder to crush energy use efficiency and its imposed by the relationship between the rate very closely. Because there is usually a time lag between the maximum load and cause smash. Therefore, to maintain fully the role of time, a smaller force will cause the particles smash. The energy applied and crushed time interval is a function of applying energy rate. Imposed by the faster, the lower the efficiency of energy use. Not difficult to infer the energy available to the grinder is nothing more than consumption in the following aspects:
(1) consumption on the elastic deformation of crushed before the particle itself;
(2) non-elastic deformation caused by the crush;
(3) the grinder itself elastic torsional change;
(4) to overcome the frictional resistance between the particles and between particles and parts;
(5) to produce crushed in noise, heat and vibration;
(6) the friction loss of the grinder itself, the working parts.
The analysis estimates that approximately only consume about 10% of the power effectively to make the crushing process to rationalize the use of energy, is the purpose of research filling process of crushing mechanism.
Interpretation of how the universal grinder operation is safe
A universal grinder out of the box, first of all carefully check whether the universal grinder damaged in transit, and high machine and auxiliary electrical control device in place, and then connected to the main and auxiliary tube road, each pipe flange assembly to be painting seals "anchor 609" liquid sealant to ensure the tightness of the pipe, stand-alone and the pipe flange with a grounding conductor to pick up, and grounded to avoid dust explosion caused by static electricity sparks.
2, each universal grinder trial operation, must be inspected inside metal objects, if that is, to exclude. The bolts are firmly reliability of the tightness of the belt guard.
3, in the following order to start the electric motor steady, close the throttle to start, shredders grading device -> dust collector -> -> screw feeder -> open the throttle -> closed wind device.
Universal grinder empty run five minutes later, the operator must carefully observe a variety of instruments on the control cabinet, to be no-load current is stabilized only after the feeding. Feeding, do not allow the current exceeds rated 32.6A, or should be reduced into to, to ensure the normal operation of the electric timing of nesting.
Universal grinder according to the following sequence stop: screw feeder -> same stop running five minutes after the smash host, dust collector, classifier -> closed wind.
6, the CVT handle manipulation of grading, you can change the speed of the classifier wheel to adjust products excellent. Such as requiring products, fine grain size can improve speed, on the contrary to reduce the speed, the larger size particles.
1, starting when the machine to normal operation,? Only allow a uniform and continuous feed crops.
2, the operation should pay attention to universal speed of the grinder motor, the thresher,? Voice and bearing temperature.
3, feeding the universal grinder operator should stand at one side of the feeding port, clothes sleeves should be fastened to wear masks and caps.
, Feeding grain stone, sickle? Tool screws and other hard objects to avoid damage to machines and made itself an accident.
5, universal grinder machine moving turn allowed to hang belts, oiling, cleaning and troubleshooting.
6, the following questions should shut down the engine to stop processing, smoke ① The motor ② The blockage, (3) crushing the poor quality of, ④ bearing overheating, more than 60 degrees.
