Reason for unshaped pellets

During the process of making pellet by wood pellet mill, the finished products are out of shape with inadequate density sometimes, or the pellets are out of shape. 
 
There are two reasons for the out of shaped pellets. The first is the material. The second is the equipment of making pellet. Specific reasons for this are analyzed like below:

Biomass Pellet Mill
 
Material:
First is the moisture content of raw material. Moisture content of material is an important indicator for making pellet. Generally, the required moisture content is below 20%, but it is not absolute. Different materials have different requirements for moisture content, sawdust like pine, fir, eucalyptus, required moisture content is 13-17% for making pellet. Second is the different property of materials. Sawdust, paper scrap has different properties and different fibrous structures, so degree of difficulty for making pellet is diverse. The material which is rather difficult for compressing is palm. 
The third reason which affects the ratio of briquette is the proportion of mixture for mixing material. 
 
Wood pellet mill:
Compression ration is a parameter of wood pellet mill, which means length of die holes divide the holes diameter. The bigger the compression ratio is, the thicker the mould is. The longer the time of compressing is, the higher of the degree of pellet making is.  As long as the thick of mould is up to a certain degree, the sawdust is fit for make pellet, and the material is not confined to sawdust. Another factor for pellet mill is the clearance between die and compress rollers. It is understandable that too larger clearance is unable to make pellet. Adjusting clearance is a technical job. Customers are welcomed to consult our technicians. The last factor is the major aspects, like the overall design of wood pellet mill, or models. For sawdust pellet mill which has high efficiency of centrifugal force, strong compression force and high rotating speed, it is a right choice. Ring die pellet mil is inferior in many aspects comparatively. 
 
Methods of resolving problems:
Failures of making pellet are controlled by the manufacture partly, and some are controlled by customers like design of wood pellet mill, quality of finished products partially. From this, choosing a reliable and large scale manufacture is guarantee. As for user, material factor are controlled by customers. If the moisture content is not proper, drying the material before making pellet is necessary. Proportion of mixing, whether the material is fit for making pellet, or what kind of wood pellet mill is fit for making pellet, the listed problems above, our manufacture would like to cooperate with clients to solve the problems. We help you to found the right model for clients material though experiments.

Wood pellet mill is a kind of fuel pellet machinery which developed by our company with cornstalk, straw, sawdust, wood flour etc. as primary raw materials according to the market requirements.  Wood pellet mill can be used as the fuel of fireplace, boiler, gasifier, and biomass power station.

 
ext to woody biomass as feedstock for the pellet production alternative resources are becoming more prominent. This development results on the one hand from an untapped potential of agricultural residues and on the other hand from a globally increasing use of wood residues and by-products for the provision of energy e.g. in the form of pellets and as raw material in the pulp and paper industry.
