First, the installation of Grinder mill
The quality of grinder mill installation quality, the ability of mill is the key to normal work. Various types of grinder mill installation method and sequence of roughly the same. To ensure the smooth functioning of grinder mill and reducing the harm to the buildings, it must be installed on the weight of its 2.5 to 3 times the reinforced concrete foundation. Should be based on a solid play in the soil, and plant and the basis of at least 40 ~ 50 mm distance.
Grinder mill installation at the outset of the main bearings should be installed. In order to avoid aggravating the shoulder of the hollow crankshaft bearings and lining wear, the two main bearing plate on the base of the elevation difference in the per metre length should not be more than 0.25 mm. Secondly, the installation of the grinder mill shell of the light of the specific conditions, can be assembled in advance of the whole Simplified loaded directly, but also can be divided into several parts to install, and should check with the adjustment of the crankshaft centerline and grinder mill, the error must ensure that concerted m in length, each should be less than 0.25 mm. Finally installation of the transmission components (Pinion, uranium, coupling, reducer, motor, etc.). During the installation process, product technical standards should be measured and adjusted. Gear inspection of the radial facing poor and small gear meshing performance of the gear reducer and small concentricity, and the motor and reducer concentricity. When fully installed with all requirements before they can conduct basic bolt main bearing floor and the last watering.
Second, operation and maintenance
To grinding mill running high rate of grinding effect, and must be in strict compliance with the operating and maintenance procedures. Starting in the grinder mill, should check whether the bolt tightening; gears, coupling, etc., as well as the keys to the mine for the first spoon-tight situation.
Check the oil tank and reducer, the adequacy of the lubricating device and instrumentation whether illnesses, and pipelines is clear. Mill equipment inspection and grading mill around there impede functioning of the debris, and then the cable car was used to Mill week, the grinding could be loose tube and ores, and to inspect the pinion gear meshing with the situation, whether abnormal sound. The start order is first launching the grinder mill lubricant pump, when the hydraulic reach 1.5 to 2.0 kg / cm 2, only allowed in grinder mill and then start grading mill. And all are in normal operation, can begin to draw mine. In the running process, we should always pay attention to bearing temperature should not exceed 50 ~ 65 ℃. Attention to the regular motor, voltage, current, temperature, sound, and so on. Attention to the lubrication system at any time, the oil tank should not exceed 35 ~ 40 ℃, to tubing pressure should be maintained at 1.5 to 2.0 kg/cm 2. Gear check size, the main bearings, the reducer-grade components, such as transmission lubrication, and after observing Mill Cover, Simplified, Pai ore bins overflow tank and mill classification back to the trough of sand plug leakage and sand. Regular attention to the changing nature of ore, according to the situation and take appropriate and timely measures.
Stop Mill, the first stop of mining millry, to be simplified after the ore processing, grinder mill motor to stop, the last stop pumps. Classifier with the upgrading of the screw device made of sand, and then stop grinder mill.
