Double Roller Granulator Press Extruder Pelleting Machine

short description:

The roller extrusion granulator is a granulating equipment. It is produced by non-drying, normal temperature process, and it is formed in one time. It is suitable for granulation of various raw materials such as compound fertilizer, medicine, chemical feed, coal, metallurgy, etc., and can produce compound fertilizer of various concentrations and various types (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer, etc.) . Especially single raw materials: raw materials such as rare earth, ammonium bicarbonate, ammonium sulfate, ammonium chloride, potassium chloride, phosphate fertilizer, monoammonium, potassium sulfate, salt, etc. Compound fertilizer: binary and ternary compound fertilizers of various proportions with a nutrient content of 17.3-53%, organic-inorganic compound fertilizers, bio-organic fertilizers, municipal sludge, domestic waste organic fertilizers, blended fertilizers, etc.

The roller extrusion granulator is also called double roller press machine, roller extruder, compactor granulating machine, etc. It has wide application either in ammonia fertilizer granulating or in compound NPK fertilizer granulating production. It is cheaper than the drum granulator production line. Its materials can be STAINLESS STEEL, and also driven by Diesel Engine. It has double shaft work and single shaft roating, normally single shaft work is commonly.

INTRODUCTION

The roller extrusion granulator is the key equipment for compound fertilizer granulation. It has advanced technology, reasonable design, compact structure, novelty and practicality, low energy consumption. It is matched with corresponding equipment to form a small production line, which can form a continuous production capacity. Mechanized production. It adopts eugenic formula, does not need to be dried, is produced at room temperature, and the product is formed by rolling, so that the product quality meets the technical index requirements of compound fertilizer. It is used to produce high, medium and low concentration special compound fertilizer for various crops and energy saving in the compound fertilizer industry. Renewal products to reduce consumption.

WORK THEORY AND FINAL GRANULES

This series of roller granulation is an extrusion sliding model. Its working principle is that the belt and pulley are driven by the motor, transmitted to the driving shaft through the reducer, and synchronized with the driven shaft through the split gear, and work in opposite directions. The materials are added from the hopper, formed by rollers, demoulded and pelletized, and passed through a pair of chains to be conveyed to the crushing screen studio, where the finished product particles (balls) are screened and separated, and then the returned materials are mixed with the new materials. Perform granulation. With the continuous rotation of the motor and the continuous entry of materials, mass production can be realized. The shape and size of the ball socket on the roller skin can be selected according to the needs of the user, and there are a wide range of choices. The ball shape includes pillow shape, semicircular grain shape, rod shape, pill shape, walnut shape, oblate shape and square shape.
