Product Description

Compared with coal, cotton stalk has almost the same volumetric heat with fast firing speed, large fire intensity, is an ideal clean fuel. Cotton stalk pellet machine is reliable with simple and convenient operation. The stalk pellet machine has wide range of raw materials such as cotton stalk, corn stalk, wheat straw, bean straw, cotton stalks, rice husks, peanut shells, corn cobs, branches, leaves, sawdust, wood waste, etc.

Cotton is grown mainly for its fibre or lint, which is the raw material in cotton textiles. But, there are other parts of the cotton plant like the stalks, husks, cottonseed and short-staple fibres, These can be used as raw materials for biomass pellets, which are made into pellets through a cotton stalk pellet machine. The finished particles after molding can be used in the fireplace, boiler, gasification furnace and biomass power generation factory. It also can be applied to the low-temperature granulation of biological fertilizer, organic fertilizer, compound fertilizer and so on.


It is widely used for pelletizing of light substances, such as cotton stalks, wood chips, sawdust, straw, pasture, chrysanthemum, palm leaf and so on;

The feeder's especial structure makes materials conveyed evenly. It is specially designed for pelletizing of light substances with the density of 0.15-0.65g/cm3;

Feeder,conditioner and chute are made of stainless steel with long service life;

It is with magnet and over load protection system which can protect machine well during production;

It makes gear directly-connecting as the driver and is with quick-release die fixed by clamps,which can increase the output by 15% more than the same type machine with belt-convey;

The bearings and oil seals in the main drivers are imported from Japan to ensure highly-efficient,stability and credibility.

I. Number of Cotton Stalks

Approximately 80 countries worldwide produce cotton, the U.S., China, and India together provide over half the world’s cotton. Other major producers are Uzbekistan, Pakistan, Brazil, Turkey, Australia, Turkmenistan, Greece, Syria and Egypt.

This statistic shows the world's leading cotton producing countries in crop year 2019/2020 (in 1,000 metric tons)

II. Nature of Cotton Stalk

The following chart-comparison between cotton stalks and cotton stalk pellets shows: with higher average density, cotton stalk pellet is easier to transport and store to lower the cost; compared with raw materials direct combustion, stalk pellet can be burnt at high temperature with high combustion efficiency.

Material Moisture Content Ash Content Average Density Diameter Calorific Value
Cotton Stalk Under 20% Dry Base 6.68% 500kg/m3 50mm 3700Kcal /kg
Cotton Stalk Pellet 0.62% 2.02% 1120kg/m3 6mm 4231Kcal/kg

III. How to Make Cotton Stalk into Pellets?

How to make cotton stalk into pellets? Need to build a cotton stalk pellet mill production line. Biomass pelletizing process refers to converting biomass wastes such as cotton stalks into bio-fuel pellets, making it easier to put it into more useful use than before. Before cotton stalks are pelletized, it's important to consider the moisture content as well as the size of the stalks. The suitable size should be less than 6 millimeters and the proper moisture content to be 18%. Then, they can be compressed into fuel pellets by use of biomass pellet mill.

As the cotton stalk pellets leave the mill, they will be soft and hot hence, the cooling process takes place to make the pellets durable and strong. All the cooled pellets will then be passed through a vibrating screen to get rid of all fines from the pellets. After which the cotton pellets are then packaged to be put into desired uses such as Biomass fuel and among other uses.

The cotton stalk pellet machine we produce is a ring die pellet machine. Ring die pellet mill is specifically designed for large-scale production of industrial biomass pellets. This equipment is mainly for wide commercial use application as it produces a large capacity of 1~20ton/h. It adopts a feeding device that is imperative making it continuous and even in its feeding speed hence very effective. The other important feature of the device is that it can be used for pelletizing biomass materials of various kinds inclueding cotton stalk, maize straw, soybean stover, rice straw and so on.
