How to ensure the smooth and reliable running of limestone grinding mill?
The working principle of limestone grinding mill:
This limestone grinding mill consists of main grinding mill, classifier, fan, bucket elevator, belt conveyor, jaw crusher, hopper, pipe system, electric control cabinet, etc.
Raw material is firstly broken by jaw crusher into required particle size (less than 15mm), which are carried by bucket elevator up to the storage hopper. The belt conveyor then conveys the crushed material at a fixed rate into the grinding chamber of the main mill for pulverizing. The rollers hung upon the spider-arm are running around the shaft. With the centrifugal force, the rotational rollers will go around the ring tightly. The raw material is put up between the rollers and rings by the blade to make the raw material into powder. The ground material is blown up to the classifier, through which the powder is separated by the classifier. Coarse particles fall back down to the grinding mill for regrinding. The needed particles will go into the collector where the finished products will be removed through the discharge opening. The purified air flows to the air blower through the pipe above big cyclone collector. Air flow is circular type. Air stream in all pipelines is negative pressure except for that in the air blower and grinding chamber, which improves the working condition in the workshop. Wind volume increases as the moisture in material changes into vapour and the air comes from the flange conjunctions and feeding-in opening. The extra air volume with some powder goes into the dust collector.
Features and Components of limestone grinding mill:
Every part of the limestone grinding mill has its own driving system, which exists in the form of independent transmission
The reducer makes the shaft go around, which forces the spider-arm to rotate. The rotational rollers hung on the spider arm on the shaft of the main unit go around the rings tightly because of the centrifugal force. The raw material lifted up between the rollers and rings is ground into powder.
The limestone grinding mill classifier consists of motor, shaft, vane wheel, housing. Motor makes the vane wheel goes round by the shaft. The limestone grinding mill blower blades move quickly around the shaft driven by the motor; and the spinning fan blade makes the air go into the air-return box. The main mill consists of grinding system and driving system.
The way to guarantee smooth and reliable running of limestone grinding mill:
1. It is necessary to ensure the coordination of various motors, shaft, bearings, spindles, etc., and regular lubrication should also be guaranteed. At the same time, when the parts are lubricated, the parts need to be inspected to see whether the parts have any damage or not, so that the equipment can be kept in good working condition, and the grinding efficiency of the limestone grinding mill is effectively guaranteed.
2. For the operation of limestone grinding mill, we need to keep the operation rules strictly and decrease the grinding mill failure rate.
3. Regular maintenance of limestone grinding mill is also necessary. If the wearing parts that are obviously worn, that should be replaced and repaired. At the same time, the limestone grinding mill should be inspected strictly to ensure that the limestone grinding mill in a good condition.
