The low yield of rice husk pellet machine may be caused by a variety of factors, including improper maintenance of equipment, inadequate treatment of raw materials, and incorrect setting of operating parameters. The following are some reasons that may lead to the low yield of rice husk granulator and their corresponding solutions:
Reasons for low yield of rice husk granulator
1. Equipment factor
Ring die compression ratio mismatch: If you are using a new ring die, check whether the compression ratio of the ring die matches the raw material produced. The compression ratio of ring die is too large, the particles are pressed out too hard, and the yield is low. If the compression ratio is too small, it may lead to poor particle forming.
The degree of smoothness of the inner hole of the ring die and whether the ring die is circular: the inner hole of the inferior ring die may be rough, the ring die is circular and the discharge is not smooth, the particles are not uniform, and the discharge is difficult and the output is low.
Cone hole and roll wear on the inner wall of the ring die: Cone hole wear and roll wear on the ring die will affect the formation and yield of the particles. Ring die cone hole wear can be reworked repair ring die, press roll wear replacement.
Improper adjustment of the gap between the ring die and the press roll: too small spacing makes the press roll aggravate the friction ring die, which will shorten the service time of the ring die; Too much spacing will cause the press roller to slip out of the material, so that the yield is reduced.
2. Raw material factor
The moisture content of raw materials is too high or too low: the moisture of raw materials is generally 12%-13% before tempering, and the moisture is kept about 14% after tempering. If the water content of the raw material is high, the tempering temperature will be affected, the tempering effect is poor, and the mold resistance and skid phenomenon will occur after the raw material enters the ring mold.
Inappropriate particle size of raw materials: the particle size is too small, resulting in poor molding of biomass particles, and the particle size is too large, resulting in not dense enough biomass particles and easy to break.
3. Operational factors
Poor finish of the die hole at the initial use stage of the mold: the new mold needs to be ground, and the mold is washed with oil mixed with sand. This problem will be greatly improved in about half an hour.
The gap between the roller and the mold is too large or too small: workers can judge according to the state of the particles and make corresponding adjustments.
The motor power is too small: In addition to the current used by the particle machine with large power, other currents are applied to the particle, and the more the remaining current, the higher the conversion rate and the greater the output.
Method of increasing the yield of rice husk granulator
Adjust the moisture content of raw materials: The moisture content of wood sawdust and other raw materials required for pressing biomass particles is about 13%. Too high or too low will reduce production.
Adjust the parameters of the pellet machine: such as the gap between the press roll and the mold. Low yield, maybe the gap is not adjusted properly. Let the manufacturer adjust well.
The new mold should be ground: limited to the mechanical manufacturing level, the smoothness in the die hole of the new mold has not reached a certain level. The grinding method is also very simple, with a mixture of oil, sand, wood chips pressed several times.
Do a good job of machine maintenance, timely replacement of the mold: a long time the mold and the press roll will produce wear, which is inevitable. If this is the reason for the decline in production, it is good to replace the new mold.
Through the above analysis and suggestions, the problem of low output of rice husk pellet machine can be effectively diagnosed and solved, so as to improve production efficiency.
