Raymond mill feeding too much material damage

Raymond mill feeding too much material will cause the following different degrees of damage:

1. too much material to increase the working intensity of the grinding roller grinding ring shovel knife, accelerate wear and tear, seriously shorten the service life of wearing parts;

2. too much material feeding mouth or conveying pipe blockage, resulting in production can not continue, affecting production efficiency;

3. too much feed mill workload increases, when it reaches a strength will cause boring machine phenomenon, and even burn the motor and other accessories.

From the above damage can be seen in the feed of too much material there is a great potential problem, improper handling may cause greater accidental failure, in order to avoid the occurrence of the above phenomenon in the amount of feed must be strictly controlled, want to solve the problem of uniform and orderly amount of material feed, manual operation is difficult to complete, for more than 75 large mill is manpower can not be, at this time you need an auxiliary equipment to complete this operation! In order to control the feeding of grinding equipment, electromagnetic vibrating feeder can be used with the silo for better results. Vibrating feeder under the action of the motor to do regular movement, the material will be uniform and orderly delivery of the bin to the grinding chamber, a device at the same time to control the feed too much or too little, uneven and other external factors on the impact of the mill. But in the milling production line only rely on uniform feeding or not enough, the size of the material and the degree of uniformity and hardness is also an important factor to consider, the hardness of the choice need to have a judgment, and the size of the material block can be realized with the help of external forces, at the beginning of the production line to install a deep cavity jaw crusher crushing and shaping to meet the requirements of the size of the material block of the mill inlet.

Raymond mill inlet there are many other failure problems, such as the inlet blowing outward, inlet spray powder, etc., in fact, these two failures can be summarized as a class, due to the milling production line within the positive and negative pressure airflow instability caused by the entire milling process we all know that the positive and negative pressure circulating wind system, the material is also in the role of the wind to complete the conveyance, breaking the structure of the wind pressure, grinding production will be greatly influenced by the possible Positive and negative pressure disorders caused by the following reasons:

1. The air door and observation are not closed or opened according to normal regulations, resulting in the air circulation is not up;

2. Conveying pipeline leakage or internal blockage, it is difficult to form a negative pressure, the air volume can not be unable to circulate, but only from the feed port exclusion;

3. The dust removal device bag accumulates too much dust, resulting in the airflow can not be normally discharged, while the fan constantly sends air to the inside, the inside reaches a saturated state, the airflow will find its own channel to exclude the outside of the body;

The phenomenon of powder spraying or blowing at the feeding port can be restored to normal operation by checking the above three causes of failure one by one.
