The cotton stalk pellet machine uses cotton stalks as raw materials to produce fuel pellets through a ring die pellet machine. Cotton stalk raw materials are very rich，This is because of cotton is the main economic crop, and it occupies about 40% of the global fiber production. The cellulose content is about 87%-90%. The highest production countries of cotton are China, America, India, Pakistan, Egypt, etc. Large production of cotton leaves huge amount of cotton wastes, the main waste is cotton stalks.The cotton stalk pellet machine is a new way to process cotton stalks. After the cotton stalk is crushed, the fuel particles are compressed, which not only effectively treats the cotton stalk, but also achieves very good economic benefits.
Cotton stalk pellet machine is developed according to the needs of the market, it is the equipment which takes corn straw, cotton straw, rice straw, sawdust, wood powder, sawdust, peanut shells, rice husk and other agricultural wastes as raw materials to make them into pellet fuel. 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.

High Heating Value
In terms of heating value, heating value ( or calorific value) is essentially a material for burning as fire or as a thermal source of energy. There is a calorific energy analysis in cotton plants could be helpful in developing highly applicable and productive planning for energy policies. The results shows that the calorific energy in different organs of cotton is different. The lowest calorific energy value in all plant organs was observed at leaves(15.955 KJ/g), while seeds contains the highest energy value varied between 22.750-23.078KJ/g. The calorific values of dry cotton stalks are varying from 15.861 to 15.100 KJ/g. (the following figure shows calorific energy distribution in cotton plant organs)
Compared with other crop residues, the calorific energy of wheat straw, rice straw, corn stalk, soybean stalk are 17.98, 17.12-18.68, 15.40-18.25, 21.81-23.01 KJ//g, respectively. Therefore, cotton stalk can be used as pellet fuel in the respect of heating value.
Low Moisture Content of Cotton Stalk
Water is one of the most useful agent that are used both as a binder and lubricant. Therefore water is particularly necessary as an aid in pelletizing. Several investigations of different materials indicate that the strength and density of pellet increase with increasing moisture until an optimal level is reached. The optimal moisture content for agricultural residues to be pelletized ranges between 8-15%. Cotton stalk moisture content is in this range. The stalks are left on the field, thus losing about 80% of their moisture in about 5 days. That means the stalk moisture content reaches the recommended range in a time period of less than one week. This implies that cotton stalks can be pelletized one week after the harvest operation is finished without incurring any additional cost for drying.
High Bulk Density
Bulk density is the ratio between the weight of the pellets and the amount of space they take up. It reflects the amount of solid material packed into the pellet and therefore has a relationship to the heat content of the fuel. Lower bulk density may result in lower conversion efficiency, as it gives rise to poor mixing characteristics and nonuniform temperature distribution, both of which may create unfavorable operating conditions in the thermochemical conversion systems. On the other hand, higher bulk density may result in lower transportation and storage costs and lower emissions during combustion. A good quality pellet will have a density of 650kg per m³. The pulverization of cotton stalk can increase its density to 1080kg per m³.
