Function of Mineral Powder Double Roller Press Granulator

Double roller press granulator can be used to press various powders, wastes and slags, such as pulverized coal, iron powder, coke coal, aluminium powder, iron scrap, iron oxide scale, carbon powder, carbon powder, slag, gypsum, tailings, sludge, kaolin, activated carbon, coke powder, etc. The mineral powder is granulated through the extrusion roll of the machine.
Double roller fertilizer granulator is widely used in refractory, power plant, metallurgy, chemical industry, energy, transportation, heating and other industries. The material formed by granulator is energy-saving, environmental protection and easy to transport. Compare with other fertilizer granulator machine (https://www.fertilizergranulator.com/fertilizer-granulator-machine-series/), our double roller granulator has improved the utilization rate of waste, and has good economic and social benefits.

Structure of double roller fertilizer granulator

Main motor: Through V-belt, power is transmitted to reducer, reducer is transmitted through coupling, and then to the drive shaft by a pair of open gears to ensure the synchronization of the two rollers.
The passive roll of the double roller fertilizer granulator is held by the piston of the hydraulic cylinder (the constant pressure type is held by the inclined iron). The pressure of the system is guaranteed by the hydraulic circuit, the hydraulic control valve and the accumulator. The material is evenly entered into the hopper by the storage bin through the quantitative equipment. The material is evenly entered into the middle of the opposite roll by adjusting the gate on the hopper. The unit forming pressure of the compressed material on the counter-rotating roller with equal speed increases from small to large, and the forming pressure at the center line of the roller reaches a larger value. After the material passes through the line, the forming pressure decreases rapidly so that the material enters the over-pelleting state and smoothly pellets off.

The double roller granulator mainly works through the head part: the working part of the contact material is composed of the main slave shaft and the roll skin outside it. The roll skin is covered with uniformly distributed semi-circular pits. The two shafts are driven by gears and rotated relative to each other. The roll skin extrudes powder materials such as mineral powder.

In addition to mineral powder granulation, roller fertilizer granulator also has unique advantages in NPK fertilizer production process (https://www.fertilizergranulator.com/production-line/npk-fertilizer-production-line.html). The roller granulator has comprehensive functions and wide application of materials. It is our main granulation equipment.
