When scrap tires pile up like mountains, how can these “black wastes” be turned into valuable resources? The rubber powder grinding system provides the answer—this automated equipment can convert scrap tires into high-value rubber powder and recycled steel wire, achieving 100% resource recovery. Today, we’ll break down the principles, core equipment, and application value of this “tire-rebirth system” in depth.
What is a Rubber Powder Grinding System?
A rubber powder grinding system is a closed-loop scrap tire recycling solution. Through multi-stage physical processing, it gradually transforms intact scrap tires (passenger car tires, truck tires, steel-belted radial tires, etc.) into 20–120 mesh fine rubber powder and pure recycled steel wire. It is characterized by automation, high efficiency, and high resource utilization.
Its core value lies in solving the pain points of “difficult handling and high pollution” of scrap tires. Meanwhile, the produced rubber powder can be used in downstream industries such as rubber products, building materials, and modified asphalt, while the recycled steel wire can be remelted and reused—truly turning waste into high-value resources.
Core System Equipment: The “Processing Team” from Tire to Rubber Powder
A complete rubber powder grinding system consists of multiple specialized devices working in tandem, each undertaking a key processing step:
1.Tire Shredder
Motor Power: 75HP (≈55kW)
Function: As the “first process,” it shreds intact scrap tires into uniformly sized rubber blocks (similar to “rough cutting”), preparing them for subsequent fine processing.
Processing Range: Covers common tire types such as passenger car tires, truck tires, and steel-belted radial tires, adapting to different specifications of scrap tires.
2.Fiber Separator
Motor Power: 40HP (≈30kW)
Material Standard: Main structure made of A36 carbon steel; contact components made of 416 stainless steel
Function: Uses physical separation technology to completely separate steel wire from rubber in rubber blocks, producing “pure rubber granules” and “clean recycled steel wire.”
Technical Feature: No chemical agents are used; separation relies solely on physical forces (squeezing, screening, etc.), avoiding secondary pollution.
3.Granulator Machine
Motor Power: 60HP (≈45kW)
Function: Further refines the “steel-free rubber granules” into finer, more uniform rubber particles (similar to “pre-treatment before fine grinding”).
Role: Standardizes the size of rubber particles, improving the efficiency and uniformity of the subsequent grinding process.
4.Tire Grinder
System Core: 100HP (≈75kW) motor power; grinds fine rubber particles into adjustable 20–120 mesh fine rubber powder.
Flexibility: The fineness of the finished product can be adjusted according to downstream needs (e.g., 20 mesh for building material filling, 120 mesh for high-end rubber products), adapting to different application scenarios.
In addition, the system is equipped with auxiliary equipment such as a central dust collector (filtration efficiency ≥99.97%, meeting PM2.5 emission limits), vibrating grading screen (screen precision error ≤±0.5 mesh), and distribution box (IP54 protection rating) to ensure environmental protection and operational stability.
Workflow: The “5-Step Rebirth Method” for Scrap Tires
The entire processing flow is a “step-by-step, interlinked” physical processing chain:
Feeding: Intact scrap tires enter the system;
Rough Shredding: The tire shredder breaks tires into rubber blocks;
Separation: The fiber separator strips steel wire from rubber, yielding pure rubber granules + recycled steel wire;
Refinement: The granulator processes rubber granules into more uniform fine particles;
Fine Grinding: The tire grinder grinds fine particles into 20–120 mesh rubber powder;
Core Advantages of the System: Beyond “Recycling”—Efficiency and High Value
This system has become a mainstream scrap tire recycling solution due to four key features:
Low-Temperature Operation, Durable Equipment: Uses a water-cooled temperature control system; the entire processing temperature is ≤50°C, avoiding rubber aging due to high temperatures while extending equipment service life;
Modular Design, Customizable Configuration: Equipment can be flexibly combined according to capacity requirements (1100–22,000 lbs/hour), adapting to small recycling plants and large industrial parks alike;
Easy Maintenance, High Safety: Equipment design prioritizes ease of installation, replacement, and maintenance, reducing operational costs and safety risks;
Full Inspection Before Delivery, High Stability: Each device undergoes 48 hours of continuous testing before leaving the factory, ensuring consistent quality in mass production.
Downstream Applications of Rubber Powder: The High-Value Scenarios of “Black Powder”
The rubber powder processed by this system is a sought-after material across multiple industries:
Rubber Products Industry: Replaces part of virgin rubber in the production of seals, rubber gaskets, etc.;
Building Materials Industry: Added to concrete and asphalt to improve crack resistance and elasticity (e.g., modified asphalt pavements);
Waterproofing Materials Industry: Used in the production of waterproof membranes to enhance water resistance and aging resistance;
Sports Facilities: Serves as a raw material for plastic runways and courts, balancing elasticity and durability.
From “black waste” piled high to high-value raw materials sought after by downstream industries, the rubber powder grinding system is not just a piece of equipment—it is a typical implementation of “circular economy.” It solves the environmental problems of scrap tires while creating new industrial value.
