Rind Die Wood Pellet Machinery
Are you looking for a quality wood pellet machinery? Have your attempts unearth the best one been sabotaged by some unscrupulous manufacturers who introduce half-baked product to the market? Perhaps we need to flex muscles and look at what exactly you need to look for when trying to get a good machine. Little known to many, pellet die is arguably one of the most crucial component in a pellet mill (factory). It directly affects the overall functioning of the entire pelletizing process. This begs the question, how do we identify the best die? ls there a criterion that we can use to distinguish between the best and the rest when it comes to choosing a pellet die? While the two types of dies, .i.e. the ring and the flat dies, can be used in biomass pellets production, the ring die is most suitable for large production.
What makes the ring die most suitable for large production of biomass pellets?
First, in the ring die, the roller wears at the same rate as the die since they move in similar direction. This in turn offers uniformity and spares one the need for constant replacements. Consequently, this saves cost in the long run. Another benefit of using ring dies for mass production is the fact that they are energy efficient. While roller slip occurs more often in flat die type pellet machinery, resulting in fast wear-out due to friction, the situation is different when it comes to ring die pellet machinery.
So, what are the characteristics of a good die? Let's look at some basic guidelines on how to get a wood pellet machinery with a good die.
How to get a Good Die for your Wood Pellet Machinery?
Die’s diameter and Effective thickness: This is the first aspect that should cross your mind whenever you are out getting a good pellet machine. The two aspects directly determine the length of the pellet. You also need to keenly identify the ratio of these two aspects, .i.e. the diameter of the holes and the effective thickness. Diameter and effective thickness are quite crucial since they also dictate the material to be used in the entire process. For instance, denser materials require smaller length to diameter ratio than less denser ones and vice-versa. It therefore follows that these two variables are quite crucial and need to be identified before any purchase is made.Total thickness: This is yet another aspect of a die that needs to be observed. Generally, the total thickness of the die ought to be greater than the effective length due to stresses within the entire die. This is because the entire thickness is required to be able to withstand all structural stress within the cause of operation of the machine. While normal die thickness ranges from 1 cm to 13 cm, the thicker the die, the stronger it is.Counterbore depth: This refers to the difference between effective length and total thickness. This is a very crucial aspect when identifying the best die. To counterbore a die, you basically take a large drill and drill the die from outside in order to relieve pressure it exerts on the material. While counterbores come in either tapered or square bottoms, there are some cases where the material is excessively expanded as the pellet leaves the hole. Tapered counterbores ate most effective when one wants to minimize the tendency of materials hanging on the counterbore. Some other materials may also require the counterbore to relieve pressure resulting in better performance.Inlet diameter: Inlet diameter is also quite crucial when it comes to selection of a good die. Good diameter results in more effective function of the entire machine. This is why the inlet diameter should be perfect.Inlet angle: Last but not least, the inlet angle is quite crucial. Although the die assumes its accurate position upon use, the angle needs to be accurate in the initial stages. Although counterboring could be sued to rectify the angle to some extent, the hole pattern can also be regulated to enhance productivity and at the same time increase abrasion resistance which enhances quality. Heat treating is one way of making a die come out in the desired design for abrasion resistance or toughness.In a jiffy, getting a quality wood pellet machinery is a task that requires one to exercise utmost caution before deciding on the one to purchase. Special attention needs to be focused on the die of the pellet machine.
