Advantage

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