VSI sand making machine is a new type of sand making machine, which can save energy by 50% compared with traditional sand making machine. The VSI sand making machine combines the two principles of "stone hitting stone" and "stone hitting iron". It uses deepened material to pass through the flow channel. It has the advantages of larger one-time processing capacity, higher sand forming efficiency, long life, simple replacement of parts and easy operation. , It has the functions of rough grinding and fine grinding at the same time. But even the best machine will be damaged under high-intensity work, so we must pay attention to daily maintenance.
1. The body of VSI sand making machine vibrates too much
Reasons: the impeller wears severely and causes the impeller to fail; the feed size exceeds the specified standard and the feed is uneven; the impeller flow channel is blocked; foreign matter enters the crushing cavity, which is difficult to be broken, etc.
Solution: Regularly check the wear of the impeller and replace it with a new impeller in time; the feed size meets the specified size of the machine, and the bulk material can be finely crushed; clean the blockage in the impeller flow channel in time; for the difficult to crush foreign matter in the crushing cavity Must be cleaned up in time.
2.The idling resistance of the VSI impact sand making machine is too large：
Reason: foreign objects such as materials have entered the bearing seal cover, and the inflexible operation of the bearing has increased the no-load resistance.
Maintenance method: Open the sealing cover of the bearing and clean out the foreign matter.
3. The VSI sand making machine makes an abnormal noise during the working process：
Reason: The connecting bolts, liners, impellers and other vulnerable parts inside the sand making machine fell off.
Solution: Fasten and install the loose or falling parts.
4. VSI sand making machine's discharge granularity becomes larger
Reason: The V-belt of the transmission part of the equipment is loose for a long time, and the operating efficiency of the impeller becomes low; the feed size is too large and the collision and crushing cannot be sufficient.
Solution: Adjust the belt tightness; choose the feed size of 4-5 cm.
The above are the problems and solutions that VSI sand making machines are prone to at work. If you have any questions, please feel free to consult.
