YUSHUNXIN is a company known for manufacturing various types of compost pelleting machine. We adopts advanced technologies on equipment manufacturing. From equipment design to compost pelleting machine paint spraying. Here, as an example, we will show you the process to manufacture double roller granulator.

How to design double roller granulator?

In order to manufacture quality double roller granulator, we strictly control from the design. So, we will do processes as follows:

Understand the requirements from compost granule fertilizer suppliers. And market demands and regulatory standards of roller press granulator of organic compost.

Develop initial design concepts of YUSHUNXIN double roller pelletizer based on the desired capacity, granule size, and material properties.

Create detailed CAD models and drawings, including all mechanical and electrical components.

Use software tools to simulate the compost fertilizer granulation process with double roller extrusion machine.

Material Selection to manufacture double roller granulator

The material of the compost granulation equipment depends the final quality and service life. Therefore, we use high quality steel as material.

  • Frame and Housing material: Generally, we use Q235 carbon steel as material for the frame and main body of the compost press granulator.

  • Roller sheet material: The parts contact compost material directly. So, it needs steel with high-strength, wear-resistance. You can choose between 20CrMnTi and 4Cr13.

What is the process of double roller press machine manufacturing?

As professional granulated compost equipment manufacturer, YUSHUNXIN has years experience of roller extrusion granulator. The whole process mainly contains 3 parts:

Roller sheet manufacturing

As mentioned above, the roller sheet plays an important role in double roller granulation machine manucturing. A quality roller sheet manufacturing usually needs 4 steps. Including cutting raw material, hollow out, quenching and sculpture.

  • Cut raw material: Cutting column steel into required length.

  • Hollow out: Removing the center of the cylinder steel to form the basic style of the roller sheets.
  • Quenching: This process make the roller sheet surface smooth.

  • Sculpture: Finally, carve ball sockets with required size on the roller sheets. This is the key to produce compost pellets with size you need.

Body production of roller press granulator

Besides the roller sheets, the body is also an important part of compost fertilizer roller granulator. For this, it usually needs 3 steps.

  • Steel plates cutting: With laser and plasma cutting machines, we can cut the large steel plate into required shape precisely and quickly.

  • Bending the plates: Moreover, according to requirements to manufacture double roller granulator, we also use steel bending equipment for more sophisticated operations.

  • Primary welding and assembling: Then, welding the different parts to assemble into basic frame. Including body part, roller sheets, stirring teeth, bearings, etc.

Surface treatment of the dry extrusion machine

  • Hardening: Heat treatment to enhance roller durability.

  • Painting: add a color painting according your requirements
