In the tire recycling machine (waste tire recycling line) industry, many customers confuse tire shredder and rubber crusher (rubber grinding machine). Although both machines are used to process waste tires, they play completely different roles in the production of rubber powder.
Understanding the difference is very important if you are planning to start a tire recycling business or invest in a rubber powder production line.
What is a Tire Shredder?
A tire shredding machine is the primary size-reduction equipment in a tire recycling plant. Its main function is to cut whole tires or large rubber blocks into smaller pieces.
Working Purpose:
- Primary crushing (first stage)
- Reduces whole tires into 50–150 mm rubber chips
- Prepares material for further grinding
Raw Material Input:
- Whole passenger tires (after bead removal or cutting)
- Truck tires (pre-cut pieces)
- Rubber blocks from cutting machines
Output Material:
Rubber chips or strips (coarse size)
Key Feature:
- Heavy-duty shafts
- Strong torque
- High resistance to steel wire impact
In short: Tire shredder = rough crushing machine
What is a Rubber Crusher / Rubber Grinder?
A rubber crusher machine (also called rubber grinding machine or rubber powder machine) is used for fine processing. It converts rubber chips into rubber granules or rubber powder.
Working Purpose:
- Secondary and fine crushing
- Produces rubber powder (10–40 mesh)
- Final stage in many tire recycling lines
Raw Material Input:
- Rubber chips from shredder
- Small rubber blocks
Output Material:
- Rubber granules (1–5 mm)
- Rubber powder (10–40 mesh)
Características clave:
- Equipped with magnetic separator
- Fiber separator system
- Screening system for size control
In short: Rubber crusher = fine grinding machine
