The maintenance and cares of overflow ball mill [2012年2月16日，14:40:35]

The overflow type ball mill is horizontal cylinder rotating device, the outer gear transmission, two warehouse, grid type relief type ball mill.Secondary cone crusher The material is feeding device the hollow shaft into the material spiral evenly into the mill first storehouse, the warehouse liner or there were steps corrugated linings, with different specifications in steel ball, cylinder rotating centrifugal force will produce steel ball to a certain height down after, to material produced thumping and abrasive. The material in the first storehouse reach coarse grinding, through the single diaphragms in the second class, in the warehouse with flat lining board, with steel ball that will further grinding materials. Powder which through the unloading Bi board eduction, finish grinding homework.

The overflow type ball mill is in the material wet water condition of grinding machine work, Impact crusher and dry type ball mill biggest difference lies in the cover for cone, cover only a wave linings, adopts the high quality for the high manganese steel lining board, wear-resisting, low noise and high efficiency. The biggest advantage is that it can choose low grade high magnetic iron ore, can choose any size, can always rejected coarse grain of tailings.Jaw crushers Roller washing machine ore low investment, quick effect.

The overflow type of ball mill is widely used in cement, Portland products, building materials, fire-proof material, chemical fertilizer, black and non-ferrous metal processing and glass ceramics production industry, especially in the processing industry used the most common in the grinding machines.
A good mechanical and electrical appliances, check each part, then check the connecting bolts is loose and all lubricating points lubrication is normal and transmission device is normal or not reliable, protective equipment in good condition, Raw material mill be sure to check if motor electric appliance measuring appliance sensitive and carbon brush good contacts.
Second, ball mill equipment turn around any part or shall not be no obstacle.
Three, ball mill start-up, running to stand around.
Four, for ball mill after everything checked out, press the start button to start the ball mill motor, Impact breaker pay attention to current changes. The ball mill in a short time is no more than 2 times for starting, first start with second start must wait five minutes or more.
Five, start when the ball mill and any other equipment shall not be started simultaneously, must be staggered start, lest produce trip phenomenon.
Six, when the normal operation of ball mill, must strictly according to the water supply, gives the ore, Mobile crushers add steel ball regulation, it is strictly prohibited to overloaded ball mill, ball mill idling time can not be more than 15 minutes, lest appear damaged lining board phenomenon.
Seven, ball mill operation of be sure to note if the slurry, often look carefully at current, Jaw crusher voltage, feeding, water supply are running normally, every 30 minutes to check a motor, the highest temperature of 60 degrees Celsius higher than the spindle.
Eight, the work must pay close attention to the observation hollow shaft, oil ring with oil whether turning, hollow shaft temperature whether standard, if hollow shaft fever, close to the tile burning, must take immediate forced cooling measures, but not stop soon, so as to avoid the " holding shaft" phenomenon. At the same time check each lubrication part the oil, temperature, pay attention to the timing gas.
Nine, in ball mill parking must first stop before ore, etc in the machine after complete treatment concentrates, and stop water supply. And then again to stop button, and finally pulled the switch.
11, when the power without notice, should first turn off the switch, then according to the stop button.
Twelve, and every time after parking, tidy up the equipment and maintain environmental health, safe production, civilized production.
