Plant Overview
What Is a Tire Rubber Powder Plant?
The rubber powder plant physically processes waste tires into clean rubber powder at normal temperature. No chemical treatment is required for the size-reduction process, and the line is arranged to remove steel and fiber before final grinding.
The complete route includes a tire debeader, tire cutter, tire shredder, tire rasper, magnetic separation, rubber granulator, vibrating grading screen, fiber separation and rubber grinding system. Material can be collected at several stages, so the same plant can recover steel wire and fiber while producing rubber blocks, 10–20 mm rubber chips, 1–8 mm wire-free rubber pellets and 20–120 mesh rubber powder.
The commercial target should be defined before equipment selection. Confirm the tire mix, required finished powder size, expected purity, working hours and local product market. These details determine screen selection, return load, grinding duty and the final layout.
Rubber powder
High-purity finished powder in the stated 20–120 mesh range.
Steel wire
Bead steel and liberated tire wire are removed through preparation and magnetic separation.
Textile fiber
Fiber is separated from the granulated rubber before fine grinding and collection.
Process Flow
Eight Main Machines in the Tire-to-Powder Process
The sequence below follows the numbering in the YUXI process image. Each stage prepares a controlled feed for the next machine; stable output depends on the handoff between stages, not on one machine operating alone.
Debeader Machine
Removes bead steel before cutting and shredding, reducing heavy steel entering downstream equipment.
Tire Cutter
Cuts the whole tire into four or five pieces for controlled feeding into the tire shredder.
Tire Shredder
Reduces tire sections to 50–150 mm rubber blocks for the rasper stage.
Tire Rasper
Produces 10–20 mm rubber chips and liberates embedded steel from the rubber.
Magnetic Separator
Recovers liberated steel wire before the rubber enters the granulator.
Granulator Machine
Produces wire-free rubber pellets of 1–8 mm, with fiber separated.
Vibrating Grading Screen
Grades the rubber and directs the correct particle size to the grinding system.
Rubber Grinder
Grinds clean 1–8 mm rubber granulate into 20–120 mesh fine rubber powder.
Separation and return controls within the production line
Second Magnetic Separation
A second magnetic pass after granulation captures finer steel released later in the process. The process description gives a 99% sorting rate at this stage.
Oversize Return
Material outside the selected grade is collected and returned for further size reduction rather than mixed with finished product.
Fiber Separation
Air separation removes loosened textile from the rubber granulate before the final powder-grinding stage.

Material Handoffs
Input and Output at Each Critical Stage
A production-line quotation should describe the output of every machine, not only the final powder. This makes it easier to check whether each downstream stage receives material within its intended range.
| Stage | Input | Output | Operating purpose |
|---|---|---|---|
| Tire Cutter | Whole waste tires | Four or five tire sections | Creates manageable pieces for controlled shredder feeding. |
| Tire Shredder | Whole or pre-cut tires | 50–150 mm rubber blocks | Primary size reduction before steel liberation. |
| Tire Rasper | Rough tire shreds below 100 mm | 10–20 mm wire-free rubber mulch; 99% liberated steel | Opens rubber around embedded steel so magnets can recover it. |
| Magnetic Separator | 10–20 mm chips mixed with steel and fiber | 97–98% recovered steel; rubber and fiber continue | Reduces metal carryover before granulation. |
| Tire Granulator Machine | Wire-free 10–20 mm chips | Wire-free rubber pellet 1–8 mm, fiber separated | Produces a clean, controlled feed for grading and grinding. |
| Fiber Separator | Rubber granulate and textile fiber | Textile-free rubber granulate; 99.9% textile separation figure | Protects powder quality and reduces fiber in the finished stream. |
| Rubber Grinding Mill | Clean rubber granulate smaller than 1–8 mm | 20–120 mesh rubber powder; 99.7% purity | Final fine grinding with wind and water cooling. |
Finished Product
Define Powder Quality Before the Plant Is Finalized
“Rubber powder” is not a complete purchase specification. The buyer should confirm the accepted mesh range, steel and fiber limits, product cleanliness and the intended application before the final screen and grinding configuration are selected.
Particle Size
The rubber grinding mill is stated to produce 20–120 mesh powder. The exact target should be written into the proposal and acceptance conditions.
Metal Control
Steel removal depends on effective bead removal, rasper liberation and the two magnetic separation points operating under a steady material layer.
Fiber Control
Fiber should be removed before fine grinding. Air volume, feed stability and particle grading affect the separation result.
Grinding Temperature
Wind and water cooling help control heat during fine grinding and support stable powder quality.
Return Material
Oversize particles should be returned for reprocessing instead of being allowed into the accepted product stream.
Finished Throughput
Compare capacity at the required final mesh, not only the feed rate entering the first machine.
Buyer Problems
Common Production Problems and How the Line Addresses Them
Most operating problems appear at the transfer point between two machines. The checks below should be discussed before layout approval and again during commissioning.
01Steel wire remains in the rubber
Check: rasper steel liberation, magnetic-belt loading, magnet height and belt speed. Keep the second magnetic separation point after granulation for finer residual wire.
02Fiber reaches the rubber grinder
Check: feed surges, moisture, air volume and whether mixed particle sizes are entering the fiber separator. Grade the rubber before final collection.
03Actual powder output is below expectation
Check: the required mesh, return load, tire mix, knife condition and upstream feed stability. Finer finished powder requires more grinding work.
04Rubber temperature rises during grinding
Check: wind and water cooling, mill loading and continuous feed rate. Avoid forcing excess material through the grinder.
05The grading screen or return line blocks
Check: metering, screen condition and return-conveyor capacity. The return system must carry oversize material without accumulating below the screen.
06Granulator knives wear too quickly
Check: residual steel, oversize feed and knife clearance. The granulator should receive prepared 10–20 mm wire-free chips, not uncontrolled rough shreds.
07Dust escapes at transfer points
Check: enclosure around high-drop transfers and extraction at the granulator, screen, fiber separator and powder collection points.
08The finished powder has no confirmed buyer
Check: local end-user requirements before ordering. Confirm mesh range, cleanliness, packaging and application requirements with a real downstream customer.
Machine Details
Main Equipment in the Tire Rubber Powder Production Line
The equipment must be sized as one connected system. A larger upstream machine does not improve finished output when the next stage, screen return or separation system becomes the bottleneck.
Process 03
Tire Shredder
The tire shredder handles bulky waste tires or pre-cut tire sections and reduces them to manageable blocks for the rasper. The corrected output range for this production line is 50–150 mm.
Input: whole or pre-cut tiresOutput: 50–150 mm rubber blocks
Process 04
Tire Rasper Machine
The rasper receives rough tire shreds below 100 mm, reduces them to 10–20 mm rubber chips and opens the rubber around embedded steel. Effective liberation is essential for the following magnetic separator.
Input: rough shreds below 100 mmOutput: 10–20 mm wire-free rubber mulchSteel liberation: 99%
Process 05
Magnetic Separator
The magnetic separator receives 10–20 mm rubber chips mixed with liberated steel wire and fiber. A stable material layer and correct magnet position are important for consistent recovery.
Input: rubber chips, steel and fiberSteel recovery figure: 97–98%
Process 06
Tire Granulator Machine
The granulator receives prepared 10–20 mm wire-free chips. Knife condition, clearance, screen opening and feed stability influence particle distribution and operating temperature.
Input: wire-free chips 10–20 mmOutput: wire-free rubber pellet 1–8 mm, fiber separated
Separation Stage
Fiber Separator

FAQ
Tire Rubber Powder Plant Questions
What does the tire rubber powder plant produce?
The complete line produces 50–150 mm rubber blocks, 10–20 mm rubber chips, 1–8 mm wire-free rubber pellets and 20–120 mesh rubber powder. It also recovers steel wire and separates textile fiber.
What is the tire shredder output size?
The corrected tire shredder output for this production line is 50–150 mm. The following tire rasper reduces this material to 10–20 mm rubber chips.
What is the tire granulator output?
The tire granulator receives wire-free 10–20 mm chips and produces wire-free rubber pellets of 1–8 mm, with fiber separated.
How is steel wire removed?
The debeader removes bead steel. The tire rasper then liberates embedded wire, and magnetic separators recover steel before and after granulation.
