1 - 2mth Double Roller Granulator Double Screw Extruder 11 - 22kw Power

1-2MTH double screw extruder, lab twin screw extruding machine

Introduction

Powdery material(chemical/mineral/fertilizer) is fed into the hopper quantificational and uniformly through the feeder to make sure a certain level inside of the hopper. After being pre-compressed by the longitudinal cone spiral in the hopper the material will be sent into arc chutes of two rollers. Half-oblate arc chutes are uniform distributed on the surface of two rollers. Under the driving of a couple of gears, the two rollers rotate inversely with constant speed. As the volume decreases through the region of maximum pressure, the material is formed into a solid compact or sheet and fall into the grinding & classifying system. Products that meet requirements will be collected from the discharging port and the rest will return back to the hopper through recycle system.

Without any intermediates or additives, this machine can produce uniform and densified particle products directly from raw powdery material. The design of this roll compactor is reasonable, and easy to operate, it’s an idea choice for dry powder granulation.

The raw materials have wide adaptability and high granulation rate It can produce compound fertilizers of various comcentra ions and types
