Double roller extrusion granulator

Product overview

The double roller extrusion granulator is an efficient equipment that directly compresses powder raw materials into uniform particles through twin-roller extrusion molding technology. It is widely used in chemical industry, metallurgy, pharmaceutical, agriculture (fertilizer/feed) and other fields. It is suitable for the granulation needs of various dry powder or wet powder materials. It has the characteristics of high pelletizing rate, uniform particles and easy operation.

Features and Advantages

01. Feeding system: The raw materials are evenly transported between the double rollers through the spiral feeding device.
02. Extrusion molding: The two rollers rotate in opposite directions under the action of hydraulic or mechanical pressure to forcefully squeeze the material and form it into cylindrical or oblate particles through the die holes.
03. The roller body is made of metal with anti-corrosion, wear-resistant, and impact-resistance characteristics, improving production capacity.
04. Discharge and crushing:The extruded flake materials are cut into uniform particles by the crushing system, and the finished products are output through the screening system.

Complete production line process

How to use a double-roller granulator to produce granules with greater capacity?

Choose a double-roller granulation production line to meet your needs. Its production capacity can reach 1-100t/h, including one-stop service from crushing, mixing, granulation, screening, crushing to packaging.

This production line has the advantages of high production efficiency, good particle strength, energy saving and environmental protection, and is widely used in chemical, fertilizer, feed and other industries. The material is evenly fed through the feeding system and enters the counter-roller extrusion device.

Under the strong extrusion force of the two relatively rotating rollers, the material is pressed into flakes and broken into particles. Subsequently, qualified particles are screened out through a screening system, and unqualified particles are returned for reprocessing.
