The hammer mill cardboard grinder is an indispensable key piece of equipment for waste paper recycling line, which crushes and screens waste cardboard and other materials through high-speed rotating hammers and sturdy screens, quickly refining waste paper into reusable cellulose material, making an essential contribution to environmental protection and resource recovery.
Raw Material of cardboard grinder machine
A cardboard grinding machine is mainly used to crush waste cardboard materials into cellulose materials, and its raw materials mainly include:
- waste cardboard: waste cardboard materials such as discarded cardboard boxes, packaging cardboard, cartons, etc. are the main source of raw materials.
- paper waste: including discarded books, magazines, newspapers, documents, printed matter, etc.
- cardboard: such as cardboard folders, cardboard packaging, cardboard patches, and so on.
These raw materials are processed by the cardboard grinder, which can quickly pulverize waste paper such as cardboard and paper into small particles or cellulose material for subsequent recycling or manufacturing of new paper products. This helps in the recycling of waste paper and sustainable utilization of resources.
hammer cardboard crusher Finished product Applications
The finished product of the cardboard grinding machine is processed cardboard waste, usually in the form of small particles or cellulose material. These finished products have the following characteristics and applications:
- Pulp raw material: after shredding, cardboard waste can be further processed into pulp for the manufacture of new paper and paper products.
- Decorative materials: Some of the shredded cardboard waste can be used to make decorative materials, such as cardboard pattern boards, cards, packaging materials, and so on.
- Insulation materials: cardboard waste after shredder processing can be used to make insulation materials, such as heat insulation boards, and insulation materials.
- Fillers: small particles of cardboard waste can be used as packaging fillers, filler materials to fill spaces, protect items, or add stability to packaging.
In short, the finished products of cardboard grinders are multi-functional and can be effectively utilized in several fields, contributing to resource recycling and environmental protection.
Waste cardboard grinding machine working principle
Feeding:
Waste cardboard or other paper wastes are first conveyed to the feed opening of the cardboard grinder pulverizer, where the raw materials are usually fed into the machine using a conveyor belt or other means.
In the high-intensity operation of the hammer blade working process, to protect the machine’s back shell, we added a pad plate inside, which makes the machine not easy to damage, more wear-resistant, and longer life.
Crushing process:
Once the raw materials enter the machine, they are subjected to the action of high-speed rotating blades, hammer blades, or rotating discs.
These blades or hammers cut, tear, and crush the raw materials, breaking them down into small pieces or cellulosic material.
Screening and Separation:
During the pulverizing process, some smaller pieces of cellulose will be sent to the screen mesh to be screened out to the desired particle size.
The size of the screen can be adjusted as needed to control the particle size of the finished product.
Finished product collection:
After shredding and screening, the finished product is discharged from the cardboard grinder outlet and can be collected or conveyed to the next processing stage as required.
These finished products are usually shredded waste cardboard chips or pulp material. Dust generated in the production process is absorbed by a dust remover.
The cardboard box grinder’s main features
Cardboard grinding machines offer a variety of advantages that make them indispensable in the waste paper recycling and pulp manufacturing process.
- High efficiency: These machines usually feature high-speed rotating blades or hammer blades that can quickly pulverize large pieces of cardboard, increasing the efficiency of waste paper processing.
- Particle size control: The operator can adjust the settings of the cardboard grinder as needed to control the particle size and quality of the finished product for different applications.
- Reduced storage space requirement: After shredding large pieces of waste cardboard, the size of the finished product is significantly reduced, which can save space costs for storage and transportation.
- Environmental protection: The waste cardboard grinder helps to reduce waste accumulation and landfills, which is good for environmental protection and waste management.

Common parameters of cardboard Grinder
The performance parameters of a cardboard powder crusher, a key piece of equipment used in waste paper processing and resource recovery, are critical to ensuring efficient and sustainable operations. Below are some common parameters used to describe two hot models of paper shredders:
| Model | SL-90 | SL-1000 |
| Motor | 55KW | 75KW |
| Hammers | 50pcs | 105pcs |
| Fan | 7.5KW | 11KW |
| Dust remover | 5PCS | 14PCS |
| Cyclone diameter | 1m | 1m |
| Capacity | 2-3T per hour | 3-4T per hour |
This machine can subsequently be combined with a pulping machine and finally go through an egg tray machine to complete the recycling of waste paper.
We have many different models available to meet different production needs. If you want to get more information about the technical data of the models, please feel free to contact us.
