Crusher in the overhaul, after the repair is completed, the no-load test time, usually 2 ~ 6h, time can also be determined depending on the circumstances. Before the test, if the rotation of the eccentric shaft crane cranes week to determine when unimpeded compound crusher, before driving. Load car should meet the following requirements: (1) the start and stop the program starts, the electrical part of the system shall comply with the relevant chain maintenance requirements; (2) the fastener should be firm, not loose; (3) lubricate all lubrication points normal no leakage; (4) bearing temperature should not exceed 30 ℃; (5) the flywheel steady rotation; (6) all flexible adjustment mechanism, and achieve the required adjustment range. Load test after passing the test should be carried out load. Load test of time, usually 2 to 3 days and nights. Load test meet the following requirements: (1) crusher may be cyclical and significant impact sound; (2) bearing temperature should not exceed 40 ℃; (3) crushed product size that is the port of discharge gap to meet the requirements. Preparation of aerated concrete material relationship with aerated concrete feed mill in the most important equipment is the ball, rotating cylinder in the process, the grinding media have dropped the phenomenon, in the fall during the feed material to the abrasive action, in order to effectively utilize abrasive effect, end the material for grinding steel, grinding the material passing discharged from the discharge end of the hollow shaft, small particles of feed material were finely ground when the machine is a horizontal cylinder rotating mechanism cone crusher, outer gear drive, the two positions, lattice-type ball mill. Built with different specifications steel ball, rotating cylinder produces centrifugal force to the ball a certain height After the fall, have severe impact on the material and abrasive. The material in the first position coarse grinding, the material to further grinding. Powder is discharged through the discharge grate plate to complete the grinding operation. Only material to the required fineness of grinding and only after mixing interaction, in order to make products to strength, grinding production of aerated concrete is an important program, a ball mill is a horizontal simplified, out of the hollow shaft and grinding head roll crusher parts, simplified for the long cylinder, to be selected according to the particle size of milled material, material from the mill feed end of the hollow shaft into the cylinder body, the time when the ball is rotated Simplified, grinding broken due to inertia and centrifugal force machine, frictional force, making it near post was taken away on a cylinder liner cylinder, ball mill used by the feed device into the compound evenly into the air shaft spiral mill first warehouse, the warehouse has ladder liner or corrugated liner, built with different specifications steel ball, rotating cylinder produces centrifugal force to the ball a certain height After the fall, have severe impact on the material and abrasive.
