The double-roll extrusion granulator is a device that uses the pressure and friction of the material itself to press the material into a sheet or strip between two relatively rotating rollers, and then cut or crush it to make the required granular products. The double-roll granulator is widely used in chemical fertilizer, metallurgy, mining, building materials, energy and other fields. It is a high-efficiency, energy-saving and environmentally friendly granulation equipment.
For Pricing and Further Details
Granulator Mechanism: The granulator employs a motor-driven pulley system to power a pair of high-pressure rollers connected by a reducer. Split gears facilitate relative work between the rollers, achieving efficient material shaping.
Production Process: Material enters the granulator, is extruded by the rollers, then moves to the crushing studio below. Power from the active pressure roller shaft drives crushing rollers via a chain system. Finished particles exit through a screen chute.
The main application objects of roller extrusion granulator are fertilizer raw materials. Used to produce high, medium and low concentration special fertilizers for various crops.
The double-roll extrusion granulator is a non-drying granulator. Extrusion shapes include pillow shape, hemispherical shape, rod shape, pill shape, walnut shape, oblate ball shape and square bar shape. It can be used for granulation of various types of raw materials (including organic fertilizers, compound fertilizers, inorganic fertilizers, biological fertilizers, magnetic fertilizers, etc.).
It is the main supporting part of the double-roll granulator, which bears the weight and operating load of the entire equipment. It is usually welded by steel plates and has sufficient strength and rigidity.
The roller is the core component of the double-roller granulator, responsible for pressing materials into sheets or strips. It directly contacts the material and is composed of several parts, including the bearing housing, bearing, shaft head, shaft sleeve, and roller skin. The roller skin, typically made of high-hardness, high-strength, and high-wear-resistance alloy steel, has surface grooves or holes of various shapes and sizes to accommodate different granulation requirements.
The pressure roller device is a crucial component of the double-roller granulator, responsible for adjusting the pressure and gap width between the rollers to ensure uniform and dense sheets. It consists of hydraulic cylinders, hydraulic pumps, oil tanks, pipelines, and valves, allowing pressure and direction control via the hydraulic system.
The feeding device is essential for roller granulators, ensuring even material distribution between the rollers for consistent and dense sheets. It consists of a hopper, a screw conveyor, a speed-regulating motor, and other components, with the feed rate controlled by adjusting the motor speed.
The cutting device is an accessory for the double-roll granulator, used to cut sheets or strips from between the rollers into granules of desired length. It consists of a knife holder, a blade, a transmission device, and other components. The blade's speed and direction are controlled by the transmission device.
The crushing device is an accessory for the double-roll granulator, breaking sheets or strips into particles of desired shape and size. It comprises a screen, hammer, rotor, casing, and other components. The rotor drives the hammer to rotate at high speed to strike and shear the material.
