Process Flowchart

In single pass dryer, wet furnish is mixed directly with hot gas inside the rotating insulated drum. The wet materials and hot gas normally flow concurrently through the dryer so the hottest gases come in contact with the wettest material.
The product is dried with hot gas at 350 ºC approx. in the rotary drum. The rotary drum is divided into different sections for a higher efficiency in the execution of the dehydration. In the first contact between the vapor and the product, a spontaneous evaporation is produced resulting in a temperature drop to 150-180 ºC. Immediately after, a slow and progressive drying takes place until reaching a temperature of 95-110 ºC at the outlet of rotary drum.
The rotation of the drum, with the aid of flights, lifts solids in the dryer so they tumble through the hot gas, promoting better heat and mass transfer. Hot flue gas can be fed directly into the dryer. Other options include using a burner or a steam heater to raise the temperature of incoming air.
The exhaust gases leaving the dryer may pass through a cyclone, multi-cyclone, baghouse filter, scrubber, ESP or WESP to remove any fine material entrained in the gas. An ID fan is usually placed after the emissions control equipment to reduce erosion of the fan, but may also be placed before the first cyclone to provide the pressure drop through downstream equipment.

Main Features

1. Low Speed of Electric motor
High Torque from low speed will make sure good quality of pellets
2. External Cooling Tower make sure the long operation time each day (occassionally, 24/7 will be acceptable. )
3. Helical Gear box
Std of Accuracy of CNC machining same as Wind turbine gear box Grade 6, less than 0.8μm
4. Fully surrounded air will cool down the ring die and lower down the ash inside pellets.
5. No Bearing inside roller shell (underneath）
Unique patent design, save huge cost of grease and bearing and shorten the breakdown time
6. Innovated bearing system for pellet cutter low down the noise and vibration of pellet mill
7. Several Glass Viewing Window visualize the lubrication system inside the pellet mill.

8. 13 Years experience to develop biomass pellet mill.
9. Local team for after sales technical support.
10. Deploy new technology for production line and consumable parts.
11. Customized design and build
12. Hands on plant operation experience.
13. Monthly Capacity for our pellet mill is at least 30% higher than any other brands of pellet mill with sameoutput ofeletric motor (Energy is saved by 30%)
14. Monthly cost of spare parts (bearing/grease), since we do not have consumption of bearing and grease, the operational cost is only the ring die and roller shell oil seal, aramid packing, etc. Only 1/3-1/2 ofthe the other brands. (refer to the bar chart for consumption of bearing/ grease and service time of roller shell/die )
15. Monthly profit will be higher than other brands of pellet mill of same output.
