3 Features Center Drive heart ball mill drive using the most advanced transmission structure, performance several times, here to talk about three characteristic center drive mill. 1, fluid couplings improve starting performance center drive ball mill price achieved using hydraulic coupling mill phased start. Coupling the pump motor coupled to the energy transfer from the motor wheel to get to work the oil, when the motor load starting speed reaches a certain value, the working oil high-speed impact with the load coupled turbine, thereby driving the load; later when the working oil to reduce energy and went back to the pump wheel again absorb energy, so cyclical, implement pump wheel (active) transfer and energy turbine (driven) between. 2, between the grinding dust, contaminants can enter the backlash, combined with lubricating oil spills easily inconvenience, poor gear meshing condition, there are impurities resistance, so that the transmission efficiency is low, only 93%, and noisy; Single Gear reducer transmission efficiency of only 94%, both an overall efficiency of 88.7%. center drive mill adopts gear reducer, transmission ratio, compact structure, smooth operation, low noise, easy maintenance, transmission efficiency up to 96% over the The conventional mill drives efficiency by 7.3%, better energy-saving effect. 3, the main bearings Cylindrical roller bearings mill at full capacity starting heavy equipment, requiring the main bearing has a larger carrying capacity. Conventional mill hollow bearing babbitt bearing, as oil lubrication. However, such bearings and lubrication have the following disadvantages: instant start, before the mill has not yet reached the critical speed to form a lubricating film, since the main bearing lubrication is still in an incomplete state, causing the ceramic ball starting torque multiplied, start-up time is also long power grid impact and influence greatly. When the mill operation, the lubrication system, high energy consumption; the mill due to start primary bearing in poor lubrication of bush scraping and other high-precision machining, or easy to produce high temperature and bush-burning, especially for new bearings. Mill startup and shutdown sequence has a certain order to start and stop the ball, all in accordance with the order to avoid omissions or irregularities caused by the accident. To mill good operation must have knowledge not only to grasp, more practical to go deep ball mill operation. Start: The first ball to start debugging, and then follow the order are: feed unit motor, main motor, high pressure pumps, the low pressure pump. At this time, a dry ball mill, to be noted that: Under normal circumstances, should not be within one hour twice to start the ball mill. Stop: ball down the order are: stop feeder, stop the main motor, ball mill price, high-pressure pump starts automatically stopped rotating ball, stop the low-pressure pump, Benxi mill, according to the bearing temperature high-pressure pumps stop, then (manually) 30 minutes on the high-pressure pump 2 minutes (until the cylinder was cooled to room temperature) intervals. Automatic spray lubrication device system operation when the main motor is working. When the main motor is stopped automatically shut down. When the main motor is operating, mill manufacturers, slow drives can not start work when the slow-driving device, the main motor can not start. _ North mine mill prices Zhongcheng (certified) _ Benxi ball from Shenyang North Mine Zhongcheng machinery Limited.
