Optimal solutions for powder extrusion granulation

Roller Extrusion Pelletiser

Roller extrusion granulator Overview

Roller extrusion granulator is a kind of high-efficiency granulating equipment. It is mainly composed of feeding device, roller extrusion parts, transmission device and so on. When working, the material is forcibly fed into the roller, and under the huge squeezing pressure of the roller, the material is extruded into granule through the mould.

Features and Advantages of Roller extrusion granulator

Features and Advantages

High quality pellets

The pellets have regular shape, uniform size, high compactness and smooth surface. Whether it is used as fertiliser or other products, it has good appearance.

Wide material adaptability

It can handle many types of materials, including organic fertiliser raw materials, compound fertiliser, chemical raw materials, feed raw materials and other powdery materials for granulation.

Adjustable pressure

The pressure between the rollers can be adjusted according to the characteristics of the material and the hardness of the required granules. It meets the requirements of different products on the strength of granules.

Easy to operate

Workers can easily master the adjustment of key parameters such as drum speed and feeding speed. New employees can be skilled in operation after simple training.

Working Principle of Roller extrusion granulator

Working Principle

When the roller extrusion granulator is working, the material is fed into the rollers evenly by the feeding device. The motor drives the rollers to rotate relative to each other, exerting extrusion force on the material, so that the material is extruded and formed in the die holes or grooves on the surface of the rollers to form columnar or flake particles. Subsequently, the particles are processed into the required size by the cutting or crushing device, and then screened by the screening device. Qualified particles are output, and unqualified particles are returned for

Roller extrusion granulator Application Scenarios

Application Scenarios

Fertiliser production area

It is widely used in fertiliser production. It can extrude all kinds of organic fertiliser or inorganic fertiliser raw materials into granules with high density and strength, and more lasting nutrient release.

Feed Processing Industry

Feed Processing Industry Roller Extruder Pelletiser can mix and pelletise corn meal, soybean meal, fish meal and other raw materials to make nutritionally balanced pellet feed.

Snowmelt production

It can mix the various components of snow-melting agent, such as sodium chloride, calcium chloride and other salts with additives such as corrosion inhibitors and then granulate. It is easy to store, use and transport.

Pharmaceutical industry

In the pharmaceutical industry, roll extrusion granulators mix and granulate drug powders and excipients to ensure accurate drug dosage.

Roller extrusion granulator Buying Guide

Buying Guide

According to pellet quality requirements

If uniformity, firmness and regularity of shape of the granules are required, it is necessary to choose equipment with high roller precision and high mould quality.

Adjustability of moulding pressure

Depending on the material to be produced and the strength requirements of the target pellet, a machine with an appropriate range of pressure adjustment is selected.

Inspection of counter roll design details

The counter roll is a critical component, so it is important to observe the design of the counter roll. This includes the diameter, length and surface texture of the roll.

Focus on mould characteristics

Focus on mould characteristics as mould quality and design affects particle shape and dimensional accuracy. Choose equipment with high mould accuracy and durability.

Examination of safety measures

Check that the stops are in place to contact the rotating roller guards; and that the overload protection emergency stop button is easily accessible and effective.

Compact construction

The length, width and height of the measuring device ensure that it can be logically placed on the production floor. Compactness also reduces vibration and noise during operation.

Frequently Asked Questions.

Roll extrusion works without additional heating or complex power systems compared to some traditional pelletising methods. It can save a lot of energy while ensuring efficient granulation, reducing your production cost and improving economic efficiency.

High-quality materials and advanced manufacturing process ensure that the equipment can run stably for a long time. The rollers and other key components are subject to strict quality testing and commissioning.

We have detailed installation instructions to guide you through the installation. Generally a flat, solid ground is sufficient, and at the same time, appropriate space should be reserved for easy operation and maintenance.

The supply of spare parts is guaranteed. We have a perfect spare parts supply system, commonly used rollers, moulds and other wear parts have sufficient inventory.

Parts that come into contact with the material (such as rolls and moulds) are made of corrosion-resistant materials, and parts that may come into contact with corrosive materials are specially coated or treated.
