If you’re in waste tire recycling but are stuck “only selling low-priced crumbs” with “paper-thin profits”; or want to enter the circular economy but don’t know “where to start most safely”—this article will explain how tire rubber powder plants turn “widely discarded waste tires” into “high-demand materials for roads and playgrounds”, as well as the full process details of setting up a plant.

I. First, Understand: The “Golden Position” of Tire Rubber Powder Plants in the Industry Chain

Waste tire recycling is not a “one-time deal”; it is divided into 3 links:

  • Link 1: Tire Collection → Rough Shredding: Recyclers cut tires into “steel-containing large blocks” and sell them to crumb plants, with a profit of about 50-100 yuan/ton;
  • Link 2: Crumbs → Steel Removal: Crumb plants turn large blocks into “steel-free rubber crumbs” and sell them to rubber powder plants, with a profit of about 100-200 yuan/ton;
  • Link 3: Crumbs → Rubber Powder: Rubber powder plants grind crumbs into “high-purity rubber powder” and sell it to end customers, with a profit of about 800-1200 yuan/ton;

As you can see, rubber powder plants are the “profit endpoint” of the industry chain—the previous links earn “hard money”, while only rubber powder plants earn “money from technology and value”.

II. 11 Processes + Hidden Details of Tire Rubber Powder Plants

Many people think “grinding powder is just putting crumbs into a machine”, but truly producing “99.9% purity” rubber powder relies on “detail work” in 11 processes:

Bead Pretreatment: Replace “Manual Prying” with “Hydraulic Cutting”

  • Use a hydraulic bead cutter to “cut and peel off” the steel bead at the edge of the tire, which is 10 times more efficient than manual prying and avoids steel residue;
  • The peeled steel bead can be sold separately for “3000 yuan/ton”, earning an extra 500 yuan/ton compared to mixing it in crumbs.

Tire Cutting: “Rotary Cutting” Saves 30% Electricity Compared to “Linear Cutting”

  • Use a rotary tire cutter to cut the whole tire into 4-5 pieces; the tire “rotates automatically” during cutting, resulting in more uniform force;
  • Only 20 kWh of electricity is needed to cut 1 ton of tires, saving 30% compared to linear cutters.

Primary Shredding: “Dual-Shaft Opposed Cutting” Makes Crumbs More Uniform

  • Use a dual-shaft shredder (50mm blade spacing) to cut tire blocks into 50mm rubber blocks; the blades are made of “Cr12MoV alloy steel” and can process 1000 tons of tires before replacement;
  • Spray “atomized water” to cool down during shredding to prevent rubber from “sticking to blades” due to high temperature, increasing product qualification rate by 5%.

Secondary Shredding: “Hammering Type” Turns Blocks into “Granules”

  • Use a hammering shredder to turn 50mm rubber blocks into 10-20mm rubber granules; the hammer head uses a “replaceable wear-resistant layer”, reducing maintenance costs by 60% compared to replacing the entire hammer head;
  • The equipment has a built-in “screen”, and unqualified large granules are “automatically returned”, achieving 100% raw material utilization.

Primary Magnetic Separation: “Drum Magnetic Separation” Absorbs 3% More Steel Than “Suspension Type”

  • Use a drum magnetic separator (12000 Gauss magnetic field strength) to absorb residual steel in rubber granules, with a separation rate of 97%;
  • The magnetic separation drum is “covered with stainless steel” to prevent rubber granules from “being adsorbed on the drum”, increasing processing efficiency by 20%.

Tertiary Grinding: “Impact Type” Makes Granules Finer

  • Use an impact grinder to grind 10-20mm rubber granules into 1-0mm rubber particles; the grinding chamber is “lined with ceramics” to avoid contaminating the rubber;
  • Use “air and water cooling dual temperature control” during grinding to keep the rubber temperature ≤40℃ and ensure performance does not degrade.

Secondary Magnetic Separation: “High-Gradient Magnetic Separation” Captures “Micron-Level Steel”

  • Use a high-gradient magnetic separator to separate steel again, with a separation rate of 99%, even “micron-level steel debris” can be absorbed;
  • The rubber particles after magnetic separation “have no visible steel wire” and can directly connect with “high-requirement customers”.

Vibratory Classification: “4-Layer Screen” Divides into 6 Specifications

  • Use a 4-layer vibratory classification screen to divide rubber particles into 6 specifications: 0-1mm, 1-3mm, 3-5mm, 5-8mm, 8-10mm, 10-15mm;
  • The screen can be “quickly replaced”, and switching specifications only takes 10 minutes, meeting the “customized needs” of different customers.

Return Material Circulation: “Negative Pressure Conveying” Sends Large Granules Back to Grinding

  • Use a negative pressure conveying system to send the large granules screened out back to the tertiary grinder, avoiding manual handling and saving 2 laborers;
  • The conveying pipeline is “lined with wear-resistant rubber” and has a service life 3 times longer than ordinary pipelines.

Fiber Separation: “Airflow + Static Electricity” Dual Separation

  • Use an airflow static fiber separator to separate residual fiber from rubber powder, with a fiber removal rate of 99%;
  • The separated fiber has “moisture content ≤10%” and can be directly sold to “biomass fuel plants” for 200 yuan/ton.

Fine Grinding: “Colloid Mill” Produces “140-Mesh Fine Powder”

  • Use a colloid mill to grind rubber particles into 10-140 mesh rubber powder, with a grinding gap “precise to 0.01mm”;
  • The ground fine powder “feels like flour” and can be used in high-end scenarios such as “baby crawling mats” and “medical rubber products”.

III. 6 High-Value End Applications + Customer Development Tips for Tire Rubber Powder

The profit of rubber powder depends on “which customers you can connect with”—the profit difference between different applications can reach 10 times:

High-Grade Highways: “Rubber Asphalt” Is “A Must-Have”

  • Demand: 10-15 tons of rubber powder are needed per kilometer of expressway, which can extend the road life by 30%;

V. 5 Pitfall-Avoidance Tips for Setting Up a Tire Rubber Powder Plant

Do Not Buy “Used Equipment”

  • The “blades and bearings” of used equipment are already worn, which not only has a high failure rate but also affects product quality;
  • New equipment has a “1-year warranty”, and suppliers provide “free commissioning + training”, which is more worry-free than used equipment.

Do Not “Blindly Pursue Fine Powder”

  • 140-mesh fine powder has high profits, but grinding costs are also high, and market demand is “not that large”;
  • First produce “30-80 mesh medium powder” to connect with highway and waterproofing customers, and then expand the fine powder market after stabilization.

Do Not “Rely on Only One Customer”

  • Putting “all eggs in one basket” will cause the factory to “shut down” once the customer bargains or terminates cooperation;
  • Connect with at least 3-5 customers in different industries to ensure “if one fails, others will work”.

Do Not “Ignore Environmental Protection”

  • The dust and noise of rubber powder plants are “key targets of environmental inspection”, and once exceeding standards, you will be “fined + shut down”;
  • Be sure to “do environmental assessment” before commissioning, and equip with “baghouse dust collector + sound insulation room”, do not “get on the bus first and then buy a ticket”.

Do Not “Stock Too Much Inventory”

  • The “shelf life of rubber powder is 2 years”, but market prices fluctuate, and too much inventory will “occupy funds + bear price drop risks”;
  • Adopt the “produce-to-order” model, and produce after customers place orders, controlling inventory at “3-5 days of supply”.

VI. Conclusion: Tire Rubber Powder Plants Are the “Ultimate Choice” for Waste Tire Recycling

If you want to change from a “recycler earning hard money” to a “factory owner earning technology money”, tire rubber powder plants are the “most stable springboard”—you don’t need to “collect tires all over the street”, as long as you connect with “crumb plants” and “end customers”, you can “stably earn profits” in the factory.

Moreover, with the promotion of the “dual-carbon policy” and “green building materials”, the demand for rubber powder will only grow—entering now means “grabbing the first wave of dividends”.
