Crusher safe operating rules machine equipment. 1, the back-breaking equipment first hand before starting rotation of the rotor, rotor and other parts to check whether the collision phenomenon. 2, the use of units should be based on site-specific conditions, after equipped with protective devices on the V-belt, to operate. 3, can not be repaired and the cleanup operation, the non-open various doors. 4, shall not exceed the size of the added material can not be broken stones and debris. 5, the device should be fixed direction of rotation, not reverse rotation. 6, when the device is running, if found abnormal vibration or sound, you should immediately stop feeding, after the crushing cavity with material drained immediately stop the motor, stop inspection, troubleshooting, in order to continue operation in case of emergency first After stopping the motor, must be cleared before turning mill slag material crushing cavity, no-load start. 7, the workplace should not be piled up debris, and must have enough light and lighting equipment. Tips: Before crusher factory no test machine, the user must be in strict accordance with the requirements of adjustment and commissioning, in order to avoid loss of life and equipment accidents. Contact with the spherical ball corners problem tile with hollow shaft journal: Some people think that the spherical hollow shaft journal tile mating contact angle majority of small package good, at least should not be <60 degrees, it is not true, because the national building materials industry Standard JC334.1-94 first 4.3.2.1c provisions, the "contact angle package should be <35 degrees slag mill where to buy, which is summed up in accordance with a lot of practice slag mill model, in theory, the principle of slag mill, the smallest package angle depending on the material of the bearing alloy, a bearing alloy mill equipment due to the soft material, the simplified under gravity, a certain deformation of the bearing alloy, so that the contact angle is too small the package is not good, when the contact angle is relatively small package can effectively ensure the hollow shaft journal under normal conditions does not hold tile, Furthermore, since the contact angle is relatively small package, there is a large range of angles of backlash, you can ensure lubricants smoothly into the contact area, thereby ensure lubrication of the contact area and help heat the hollow shaft journal and spherical watts, we can see that the contact angle package should be <35 ° is appropriate, at this time axis Wawa surface treatment has become more efficient, easy to improve its contact surfaces quality of work. slag mill price, Yunnan slag mill, ball mill Dahua provided by Gongyi City Dahua Machinery Co., Ltd.
