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

Giant King Grass

Giant King Grass

Giant King Grass is a fast growing, high yield, perennial grass with many applications including bioenergy and animal feed. Giant King Grass is not genetically modified and is not invasive.The fertilizer requirements are modest and no pesticide is required in the current cultivation.

Giant King Grass Data

Energy: 18.4 MJ/dry kg= 4400 kcal/kg=7900 BTU/lb (GCV)

Biogas: 539-758 liters/dry kg; 51-57% methane

Biofuels: Glucan 43%; Xylan 22%; Arabinan 3% Lignin 17%

Cellulosic ethanol: 326-333 liters/dry mt (78.5-80 gal/US ton)

Cellulosic ethanol: 33,000 liters/hectare (3500 gal/acre)

Yield comparison of giant king grass VS corn stalk VS miscanthus

Notes:Giant King Grass has 10 times the yield per acre compared to corn stover. Due to the different growth environment, the above comparison isn’t entirely apples to apples. However, the advantage of Giant King Grass is obvious.

Giant King Grass Compared to Coal Pellets

Notes: Above data shows that Giant King Grass pellets have higher energy density and lower nitrogen, sulfur and chlorine content than coal.

Advantages of giant king grass as raw materials for pellet production

High yield, but low cost

Neither special care nor pesticide is needed.

Little fertilizer is used.

Easy grow and easy to process into bio-fuel, such as pellets.

How To Produce Giant King Grass Pellet?

Generally speaking, in order to get the fuel pellets from freshly harvested giant king grass, a series of procedures must be closely followed. The whole production process of giant king grass pellet include raw materials crushing, drying, pelletizing, cooling and packing.

Crushing: The giant king grass for making fuel pellet is 3-5m in height, so it must be crushed first. The grass needs to be crushed into small pieces with the size smaller than the hole diameter of the pellet mill die. Our hammer mill is no doubt a nice choice.

Drying: When pelletizing, the moisture really plays an important role. Too high or too low can affect the final pellet quality. The moisture of freshly harvest grass is approximately 70-75%, which needs to be lowered to around 10% by sun drying or the rotary drum dryer.

Pelletizing: As the core procedure of fuel pellet production, pelletizing directly influence the pellet quality. We have both flat die pellet machine and ring die pellet machine for your selection.

Cooling: Newly pressed pellets are hot and soft, which need to be cooled down to ensure the hardness and durability.

Packing: After cooling, the pellets can be packed according to your requirement.

Giant King Grass Pellets Application

Direct combustion as a replacement for coal or oil in electric power/heat/steam plant.

Applied for co-firing with coal in electric power plants to reduce the carbon emissions.

Large global demand– Particularly in Europe,Korea, China, Japan are emerging.
