How Can I Start A 1-20 TPH Complete Biomass Wood Pellet Production Line Plant?

Starting an easy to handle 1-20 TPH stable performance biomass wood pellet production line requires some basic and essential information to be put into consideration. As a China wood pellet line supplier,RICHI will tell you the following factors which need to be considered.

1. Raw Materials Species

It is important to understand that different species of raw materials have distinct traits. These traits include different fiber and lignin contents which usually affects the cohesiveness of the wood pellets. Additionally, different cohesive values of the raw materials call for different compression ratio of the pellet mill die mold. For instance, the hardwood require a lower compression ratio while softwood require a higher one. For example beech requires a compression ratio of a ring die of 7.5:1, bangkirai, meranti batu, and cruing require a compression ratio of 5: 1, and hardwood eucalyptus require a ring die of the compression ratio of 4.5:1.

It is important to note that the raw materials that are hard to pelletize require to be mixed with a binding agent such as clay, vegetable oil, starch, wax, or oil. This should be carried out from time to time. The raw material in the pelletization process passes through steam generated by the high pressure and temperature conditions. The vapor is acts as a catalyst to keep the raw material softened and cured to strengthen its cohesiveness.

2. Size Of The Biomass Material

This is another important factor that affects pelletization process and your investment in the wood pellet processing plant. Varied sizes of materials require different technological processes for the design of the pellet production plant. For instance, materials need to be reduced into required sizes using either a commercial drum wood chipper, or a wood crushing machine. For example if you use the rice husks for your raw materials, then there is no need to have any kind of crusher such as the rice husk hammer mill to reduce the sizes of the material into a standard length of between 4mm and 5mm.

However, in cases where tree twigs or branches, wood logs or wood blocks are used as the raw materials, then the machines mentioned should be employed before pouring the materials into the ring die wood pellet mill. The machine used will also depend on the size of the material used. This, therefore, means that your budget and investment in the wood pellet making plant should take care of the pre-treating equipment. The materials that are longer than the standard length do not pass through the pores of the ring die smoothly. The pellet market demands that the diameter of the pellet should range between 6mm and 8mm.

Additionally, the performance of the wood sawdust pelletizer machine is affected by the flow of electricity. If the electricity current keep fluctuating, it will cause damage to the wood pellet milling machine and the resulting pellets will be of low quality. The pellets produced in such a case will be too much mealy and of low formed pellet yield.

3. The Moisture Content Of The BIomass Material

This factor will determine whether there is need of a drying system in the biomass wood pellet manufacturing plant. Statistics and research show that the most suitable moisture range that is commonly used is 13% to 15%. However, the materials such as fresh wood or agricultural- based waste should be dried before feeding them in the wood sawdust pellet making machine. Also, the raw materials that are exposed in the open air such that they have been dampened by rainwater or soaked in snow water require their moisture levels to be lowered. Nevertheless, if such materials with excessive contents are milled before drying, they will just stick together like paste. Such materials will also affect the performance and efficiency of the wood pellet pressing machine. This, therefore, call for an adjustment on your budget to cover up the losses.

4. Different Technological Processes Due To Use Of Different Materials

Different types of raw materials can be mixed and milled together or you can just mill one type of material at a time. There are suitable projects offered based on your demands but the thing is to secure the stable performance of the mill. If using different kinds of raw materials, then ensure they are blended proportionately and thoroughly. Otherwise, the biomass pellet press machine will be compelled to chew various materials from one type to another thereby triggering burping or chocking of the biomass wood pellet press. This usually leads to instability issues in running of the mill and producing some noisy sounds.

The wood pellet pressing equipment does not usually produces no sound when running. This, therefore, means that various materials should be blended decently to achieve a smooth biomass wood pellet production. This implies that different technological processes should be put into practice and the mixer will boost the performance of the wood pelletizer machine. The wood pellet technological processes used will have an effect on your budget.

The wood pellet making process primarily involves the following procedure:

(1)Drum Chipping: The harvested wood is pre- =processed using a wood chipper to reduce their size to the required length of less than 6mm.Main machine:easy to operate industrial drum wood chipper

(2)Screening: Here the impurities are screened and removed from the raw materials. These impurities include such substances as metals, stones, etc.

(3)Drying: The raw materials are passed through the drum dryer machine to achieve the desired moisture content of between 12% and 18%. The drum dryer is the standard for the wood pellet production plant.Main machine:ce wood sawdust drying equipment

(4)Pelletizing: The raw materials of sufficient size and moisture level are channeled through the die openings under great pressure. This process extrudes the soft and hot pellets.Main machine:ring die type horizontal of wood pellet machine

(5)Cooling: Here the hot and soft extruded pellets are hardened and strengthened by air cooling.

(6)Packaging: After cooling the pellets are packaged into bags to allow for wood pellet production and convenient distribution.

(7)Storage and Distribution: The pellets should be kept under dry conditions and stored in containers, tanks, or silos. The pellets are often distributed in bulk form by truck or any other carriages or in bags.
