Description:

The heavy-duty dust-free combined waste paper crusher cardboard grinder employs a high-speed, counter-rotating dual-power transmission system for efficient material size reduction. Inside the crushing chamber, a high-mass steel V-shaped lining works in conjunction with rapidly rotating cutters to grind materials effectively, ensuring consistent and reliable discharge.
All critical wear components — including the main shaft, cutter assemblies, and spacer sleeves — undergo deep processing with quenching, tempering, and heat treatment to minimize wear during continuous long-term operation. The cutting tools are manufactured using advanced thermal processing technology to ensure superior wear resistance and extended service life.
The equipment features a hydraulic open-box design for convenient maintenance access. This allows a single operator to perform routine inspections, tool maintenance, and blade replacements with ease, significantly reducing downtime and labor costs.
The dual-power configuration increases rotational force at both ends of the main shaft, with additional pulley grooves to prevent rotational power loss at high operating temperatures, ensuring stable and efficient output.
The V-shaped wear-resistant lining plate covers up to 50% of the crushing chamber surface, maximizing material friction during the grinding process. This optimizes fiber liberation, enabling the output material to meet customer specifications for downstream pulping applications.

Working principle：

The heavy-duty dust-free combined waste paper crusher cardboard grinder is a machine that crushes the input materials through the conveyor belt. When the machine is working, the motor drives the rotor to rotate at high speed, and the materials evenly enter the crushing cavity. The high-speed rotating hammer head impacts, Shearing and tearing the material causes the material to be crushed.

The heavy-duty dust-free combined waste paper crusher cardboard grinder is mainly used for the first-pass treatment of waste paper. It breaks large pieces of waste paper raw materials into small pieces. The hammer claw rotor crushes waste paper. The crushing process is not afraid of iron impurities, gravel, etc., and can crush waste paper boxes very well. It is loose and has no extruded hard lumps, which is beneficial for attracting iron at the back and is beneficial for subsequent crushing and velvet lifting output improvement of the crusher!

Applications:

The waste paper cardboard grinder can be used for the recycling and pulping of paper tubes, paper cores, paper rolls, newspapers, cardboard boxes, waste paper boxes, packaging boxes, hard paper, corrugated paper, paper mill waste, high-grade paper, yellow board paper, edge paper, enterprise unit paper, engineering paper, books and newspapers, etc.

Features:

1. The blade of the cardboard grinder machine is a meshing blade made of high alloy, which has a good paper mill waste crusher effect on any high-hardness material;
2. The paper mill waste is crushed and the cloth-type stiffening plate is used to ensure the strength of the box;
3. Conveyor belt feeding equipment can be configured;
4. The frame plate is thick, can withstand high torque, and is strong;
5. The equipment has the characteristics of low speed, large torque and low noise.
