The accessories of any equipment have a life, the normal operation of equipment can bring us benefits, so we need daily maintenance. So how long is the service life of the ring dies of feed pellet machine and biomass pellet machine? How to maintain?
Quality is also divided into good and general of the ring die of feed pellet machine and biomass pellet machine. The service life of the feed pellet machine is usually calculated by the weight of the processed material, of general quality is around 3000 tons, that means that the ring die of general quality will be useless basically after pellet machine producing 3000 tons of pellets; of best quality is around 7000 tons. As to biomass pellet machine, the service life of general quality is around 1000 tons, of good quality is about 3000 tons.
So the price will be always adequate to the quality, the price of equipment is high for a certain reason. Secondly, the service life depends on the degree of use and maintenance. Usually pay attention to the maintenance of pellet machine ring die can extend the life:
1.Find a manufacturer with professional production technology, design and customize different ring dies according to different raw materials and practical application, in order to make full use of the ring dies.
2.The space between the roller and ring die must be controlled between 0.1 ~ 0.3mm (the space between the biomass pellet machine roller and ring die must be controlled between 1~3mm), do not let the eccentric roller contact the surface of the ring die or the space of one side too large, avoid cause abrasion of ring die and roller.
3.When the pellet machine starts, feeding must be from low speed to high speed, do not run at high speed at first, cause damage to the ring die and pellet machine due to sudden overload or ring die plugging.
Maintenance for pellet machine ring die：
1.When the ring die is not used, extrude the residual raw materials, in case the ring die heat make the residual in the die hole to be dried and hard, resulting in no material or ring die cracking.
2.Check the inner surface of the ring die for local protrusions after a period of use. If so, wear off the convex part, to ensure ring die the capacity and the service life of the ring die and roller.
3.When loading and unloading ring die, don’t use hammer and other hard tools to hammer the ring die surface.
4. The ring die must be kept in a dry and clean place. If it is kept in a damp place, it will corrode the hole and reduce the service life of the ring die.
The above is our company's experience of maintenance for ring die based on many years production and use, hope it will be helpful for customers. If you have any further questions, please feel free to contact us.

Clogging is one of the common faults in the use of the hammer mill. In many cases, when we use the hammer mill, there will be clogging of the powder materials. The reason for this kind of fault is mainly due to improper operation. If your material often blocking from the beginning, and with a period of time using, it is not blocked. It may be the new equipment is not smooth enough in the running-in period, after a period of time it becomes smooth and not blockage and the material is also smoothly to come out. There were so many times, improper operation can also cause this failure, we will give you an analysis of the general reasons and solutions in the following
First, check whether the feeding speed is too fast. If too fast,it will make the hammer mill fan plug; Improper matching with conveying equipment will cause the outlet pipe to be blocked after wind weakens or there is no wind. At this time, we should adjust the amount of feed to make the equipment run normally. Otherwise, the increase of equipment load will cause blockage. In our feeding process of hammer mill, we should always pay attention to the ammeter pointer deflection Angle. if more than the rated current, it indicates that the motor overload. If overload for a long time, it will burn our hammer mill motor. In this case,we should immediately reduce or close the material door, and we can also change the way of feeding, by increasing the screw feeder of bucket elevator to control the amount of feed.The user shall select the appropriate screw feeder of bucket elevator according to the actual situation. Because the rotation speed of the hammer mill is high, the load is large, and the load fluctuation is strong, when the hammer mill works, the current is generally controlled at about 85% of the rated current and try not to overload of our motors.
Second, the discharging pipe is not smooth or blocked. Most often we shut down hammer mill once we can not hear the sound of corn grinding, this is wrong. You should let the crusher idle for a few minutes, waiting all the materials in the material pipeline enter the mixing tank and then turn off the crusher. Otherwise, the residual materials will sometimes get wet and agglomerate after a few days, it will causes blocking of hammer mill.
Third, the hammer slice is broken, and the wear is severe, the hammer screen hole is closed to block and the broken, the water content of the crushed material is too high, which will block the hammer mill. The broken and severely aged hammer slices should be regularly replace to keep the hammer mill in good working condition, and the hammer screen should be inspected regularly. The moisture content of the material for grinding should be lower than 14%, which can not only improve the production efficiency, but also prevent the hammer mill from being blocked to enhance the reliability of the work of the hammer mill. At the peak of production, please reduce the feeding speed to ensure that the motor does not burn and the equipment does not block the material.
