Ball mill explosion, Dahua Machinery (certified), explosion-proof ball mill supplied by Gongyi City Dahua Machinery Co., Ltd. Gongyi City Dahua Machinery Co., Ltd. (www.dhqmj.com/) is specialized in the "Mill, shredder, pressure the ball machine, dryer, brick" of the enterprise, the company adhering to the "honesty, hard service" concept To provide you with the highest quality products and services. Welcome to inquire! Contact: Niu Yang. 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 stops the motor down to check, after troubleshooting ball mill explosion, in order to continue operating, After the first stop of the motor in case of emergency, the power must be removed before crushing cavity material, 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. If you open mill equipment installation, electrical protective measures are not taken, prone to electrical short circuit, UOB mechanical implementation of the control system installation program, and after repeated tuning PID parameters, put into operation on the same day to obtain satisfactory results from steady silo the amount of material can occur normally start, but frequency modulation does not go up, ball mill drive to start, but the frequency of 20Hz transferred to a small explosion when the ball from the stop tripping fault records show "motor short circuit", with a shake table to measure the motor insulation is low, only After 0.5MQ, contact welding processing power on 24 hours, insulation up to 10M (qualified), power-on test, the frequency of 30Hz transferred from the stop trip took place, still shows "motor short circuit" to open the motor and white star-shaped contact resistance measured and found U phase and W-phase phase short circuit-proof ball mill, after replacing the motor fault eliminated. Failure Analysis: mill outdoor installation, improper site rainproof measures rainfall explosion before starting the mill equipment, causing the motor to damp, not dry that is the boot phase short circuit caused by the motor locally, our approach occur: increased motor rain measures before starting the strict Detection of the motor insulation. Mill equipment is one of the main products of Dahua Machinery Co., Ltd. Dahua Machinery is one of the country's largest manufacturer and supplier of ball mill, located in the Central Plains, and convenient transportation, production quality assurance, and excellent service, in a ball mill has a good reputation on the market.
