From the advantage of the ball mill, a crushing material will be needed. After using it, the material will tend to be broken, and it also meets the requirements. In the process of running, in addition to the machine itself, it is inseparable from the auxiliary equipment. Help, which auxiliary equipment does this device?
1, high and low pressure lubricating oil station
fuel tank volume 1.6m, cooling water consumption of 3.8 m / h, cooling water temperature ≤ 28 ° C, low pressure pump 100L / min, 0.4 MPU, high pressure pump 2.5L / min, 31.5MPS. Two low-pressure oil pump devices for lubrication, one work, and another standby. Work pumps and spare pumps can be switched with each other or in simultaneous use. Two high pressure oil pumps start at the same time. The temperature of the lubricating oil at the exit is controlled between 30 ° C to 45 ° C. Introduction of the cooler, the exchange of filters is operated by manual operation, and the remaining working processes are electrical automatic control.
2, jet lubricating device
Big grinding machine, pinion lubrication adopts an automatic injection lubrication system. From a gas source, compressed air is divided into two channels within the system. All the way to send a moving oil pump, so that the air-blowing oil pump is placed in the pressure oil, the pressure oil into the current collecting chamber, so that the pressure oil and the wind are sprayed in the spray, sprayed on large, pinion. The system has sleeves 1 l / min, hydraulic pressure 6.3 MPa, wind pressure 0.4 mpm.
3, pneumatic clutch
air clutch consists of housing, inflatable capsules, brake waves, drums, and the like. When inflating to the airbag, the clutch is closed; when the gas is discharged, the clutch is disengaged. The time that the ball mill is reached from the rated rotation speed, i.e., the clutch inflation time is 6 s-8s. The pressure reducing valve of the clutch gas tank modulates the pressure of 0.7 MPa, and the safety valve is modified to 0.8 MPa. The air supply equipment is WW0.8 / 10 oil-free air compressor. In the main motor stationary state, inflate to the clutch, check if the system is leaking, discovery, and timely processing. In the main motor operation, the clutch must avoid 3 consecutive starts to prevent burnout clutches. The interval between the two starts is not less than 10 min.
These are all the auxiliary equipment of the ball mill. Although in the usual use, it may not be easy to see some of their features, but in use, with their aid, the use of the device is quite advantageous.
