1. Checking the whirlpool cavity’s observation door whether it is closed tightly, in case the materials is fired from the observation door, to cause danger.
2. Checking the rotation direction of the impeller .The impeller should rotate in the counter clockwise, or the electro motor’s wiring should be adjusted.
3. The start sequence of the breaker and convey equipment.
4. Discharge →breaker→feed
5. Breaker muse be started up under no loading condition, the materials should be fed after the breaker is in good order. 6. The sequence of shut down and start up is opposite.
7. The feed size should be according to the requirement of every kind of machine strictly, materials over the requirements must be forbidden otherwise imbalance is produced and the impeller is wired heavily, even the tunnel of impeller and middle of feed tube will be jammed, as a result the machine can not work well.
8. Feeding should be continuous and even, The huge shake and abnormal noise shouldn’t exist in the process of the operation, or the machine should be shut down and checked.

1. Special light oil lubrication system ensures the temperature is below 25℃.
2. Brand new automatic protection device supplies VSI with vibrating, oil filtering and warning systems.
3. Hydraulic system allows automatic uncovering, reducing intensity of labor and making maintenance easier.
4. Optimized arrangement design of wear resistant materials increase the service life of the machine by over 40%, thus decrease the cost by over 40%.
5. The mainframe is made with rivet hot technique, which enhances intensity of structure and tenacity, and ensures stable performance.
