Finished Product

Pre-treatment : This section is more suitable for the larger raw materials in the early stage, and it is not easy to directly crush or granulate through the crusher. But sometimes this section can be omitted. For example, the sawdust pellet production line can directly pelletize, and this section is not needed.

Crushing Section : This section is usually used in biomass pellet production line, forage gress pellet production line and nutshell straw pellet production line. For example, the SFSP hammer mill is used for wood and fruit shells, and the straw/alfalfa/husk/grass crusher is used for grass and straw. Different raw materials are equipped with different types of crusher.

Conveying Section : Conveying equipment is mechanical equipment that transports bulk cargo and unit goods from a loading point to an unloading point along a certain route in a continuous manner. The conveying equipment of RICHI machinery includes screw conveyor, scraper conveyor, belt conveyor and Bucket elevator.

Drying Section : To dry materials and remove the moisture from 50% to 15-17%. Itincludes: --Burningstove,tosupplyhotair --Drumdryer --Dischargingcyclone.

Pellet Mill: Wood pellet machine, also known as biomass pellet machine, has a wide range of raw materials: straw shells include wood, straw, sawdust, cotton stalks, rice husks, peanut shells, sunflower shells, coconut shells, coffee shells, bamboo, etc. . The grasses are alfalfa, hops, hemp, hay, grass, etc. In addition, there are organic fertilizer granulator, cat litter granulator and so on.

Cooling & Section : Pellets come out from pellet machine, its temperature is around 70℃, by cooling system, It can cool down to room temperature immediately. By momentary cooling, the hardness of pellets will become more stronger.

Screening Section : The forming rate of pellet machine is around 98 % , so there are still have 2% powder in pellets,by screening, sort out all the powders from pellets.

Packaging Section : There are three kinds of automatic packaging machines produced by RICHI machinery: powder packaging machines, granule packaging machines and (universal) dual-purpose packaging machines.

Dust Control System : A dust collection system is an air quality improvement system used in industrial production to improve breathable air quality and safety by removing particulate matter from the air and environment. Dust collection systems work on the basic formula of capture, convey and collect.

Production Line Description

coconut shell

There's a huge abundance of coconuts all over the world and it would be a waste of resources if coconut shells are just thrown away or burned. This is why engineers and scientists have come up with an ingenious way of turning coconut shells into reusable materials. The process is called pelletizing and it involves turning the discarded shells into pellets that can be used in various fields like sustainable energy production, biomass extraction, and agriculture. For the process to work, you are going to need what's called a coconut shell pelletizing plant.

Which countries produce coconut?

5 Sri Lanka 2,000,000 m/t 3.3%

Work Process of Coconut Shell Pellet Production Line

1. Crushing process

Due to the quite hardness of the coconut shell, the coconut shell needs to be crushed from big chunk to small pieces by special coconut shell crusher.

2. Drying process

For containing certain moisture, crushed coconut shell enters drying machine through conveyor and feeding machine. The dryer can dry off the excess moisture to improve the pellet strength after pelletizing.

3. Second crushing process

After drying, the coconut shell pieces need to be crushed again into small fibrous pieces for better pelletizing.

4. Pelletizing process

After entering pellet mill through belt conveyor and feeding machine, the fibrous coconut shell pieces are pelletized into regular pellets by high strength extruding of the pellet mill.

5. Cooling and packing process

Pelletized particle has certain temperature, so it needs to be cooled by cooling machine after conveyed by belt conveyor. After cooling, the high quality biomass pellet is packed by the automatic packing machine.

All the above processes are equipped with dust collector, which makes the whole process no dust pollution.

Application of Produced Coconut Shell Pellets

Because of rich raw materials and convenient processing, the products manufactured from coconut shell pellet production line are widely used to replace fossil energy which will release carbon dioxide, sulphur dioxide, nitrogen oxides, etc.

1. Industrial medium and small boiler: applied in biomass fuel plant, power station, wood processing factory, chemical plant, fertilizer factory, etc.

2. Household small stove: they can be used not only for city's heating supply but also in such service industries as hotel, restaurant and bath.

The Benefits of Setting Up a Coconut Shell Pelletizing Factory

The factory can be a great source of biomass fuel. The pellets that the factory produces can be used as an alternative energy source. If you are able to produce huge amounts of pellets, you can turn it into a very profitable business. Coconut plantations will be more than glad to sell you their coconut shells at very low prices because these are not their main products. The shells are your main ingredients. Your operating costs will largely be composed of the labor you hire in running and maintaining the machines in your factory.

Brief economy analysis of pelleting process

Raw material, operating cost of pelleting plant and personnel costs are the major factors that affect your profit. According to the following brief pelletizing cost analysis, you can reckon your budget of pelleting.

1. Operating cost of the pelleting plant was estimated that pellet production cost for a bagasse plant capacity of 6 t/h was about $51/t of pellets. Pellet plants with a capacity of more than 10t/h decreased the costs to roughly $40/t of pellets. So do not take it for granted that capacity of pellet plant is proportional to pellet production cost.

2. In the production, one or two workers are required for the entire production plant. The personnel cost for the pellet plant with 10 t/h production rate is about $4/t.

3. Raw material cost is the largest cost element of the total pellet production cost. An increase in raw material cost substantially increased the pellet production cost. Notice that the price of coconuts shells for pelletizing is around USD 100-150/t, but shells with perfect cleaning, smooth finish and equal trimming around USD 250-300/t are mainly used for handicraft materials.
