SMMVIK feeder, how VSI sand making machine achieves uniform feeding
What is the significance of the feeder
The feeder is one of the important accessories in the feeding process of the sand making machine. The sand making machine lowering barrel (lowering barrel) is usually conical. Selecting a suitable lowering barrel for uniform feeding is of great significance for continuous production and prolonging the life of the sand machine. If the lower barrel of the sand making machine is blocked or fails, it will affect the normal operation of the sand making machine equipment, so it is absolutely impossible to lack the lower barrel, and the quality of the finished sand will be greatly reduced.
How is the blanking cylinder uniformly blanked
The smoothness and uniformity of the feeding of the feeder mainly consider the following aspects: the friction coefficient of the raw material, the friction of the material of the feeding barrel (mirror stainless steel is recommended if the requirements are good), the feeding speed, the feeding speed at different angles The speed is different, generally the larger the angle, the faster the speed. At the same time, we suggest adding a control device to the sand making machine feeding barrel to control the feeding and unloading of the sand making machine.
Feeder FAQ
Problems in the feeding barrel of the sand making machine will cause the sand making machine to discharge slowly, and the discharge pipe of the sand making machine will be blocked or blocked. If the material is fed too fast, the air supply port of the equipment will be blocked; if it is not matched with the conveying equipment, the wind power of the discharge pipe will be weakened or blocked after no wind. After the fault is found, the air supply port should be cleared first, the unmatched conveying equipment should be changed, and the feeding amount should be adjusted to make the sand making machine operate normally. The feeding speed is too fast, the load increases, causing blockage.
In addition, during the feeding process of the sand making machine, pay attention to the change of the pointer of the ammeter at any time. If the feeding amount is too large, the deflection angle of the pointer of the ammeter will be large. If the rated current exceeds the rated current, it indicates that the motor is overloaded. Overloading for a long time will burn the motor. In this case, the material gate should be reduced or closed immediately, and the feeding method can also be changed, and the feeding amount can be controlled by increasing the feeder.
