In the recycling process of large scrap tires (such as those from construction vehicles and trucks), “direct shredding” often faces challenges like large volume, high hardness, and low efficiency—and the scrap tire cutting machine is the core pretreatment equipment that solves this pain point. It can cut bulky large tires into regular strips, clearing the way for subsequent shredding processes and serving as the “front-end key” to boost the efficiency of the entire recycling line. Today, we’ll break down this equipment’s positioning, applicable scenarios, working logic, and core advantages in depth.
What is a Scrap Tire Cutting Machine?
A scrap tire cutting machine (also called an OTR Cutting Machine) is the core pretreatment equipment for large scrap tire recycling lines, specifically designed for “full-steel construction machinery tires that are difficult to shred directly” (e.g., truck tires, excavator tires).
Its core function is: Using powerful cutting force, it processes intact large tires (which are bulky and high-hardness) into uniformly sized, regular rubber strips. This allows them to smoothly enter the subsequent tire shredding process, avoiding issues like “large tire jams” or “uneven shredding” at the source—and ultimately improving the efficiency and stability of the entire recycling line.
Applicable Materials for Tire Cutting Machines
This equipment is tailored for “large, high-strength scrap tires” and is primarily suitable for the following materials:
Full-steel radial truck tires: High-hardness full-steel tires used on heavy-duty freight vehicles;
Construction machinery tires: Giant tires for excavators, loaders, rollers, and other construction vehicles;
Large agricultural tires: Wide-body tires for tractors, harvesters, and other agricultural machinery;
Other hard-to-process large tires: Oversized or high-hardness tires that cannot be directly fed into shredders.
In short, it is a “specialized pretreatment tool before the shredding process” in large tire recycling, focusing on the niche scenario of “reducing the scale of large tires.”
Working Principle of Tire Cutting Machines: 4 Steps to Convert “Giant Tires to Regular Rubber Strips”
Tire cutting machines use a hydraulic system as the core power source and achieve efficient cutting through a highly automated process. The specific steps are as follows:
Loading and Positioning: The operator places the intact large tire horizontally on the equipment’s feeding platform, and the machine automatically performs initial positioning of the tire;
Hydraulic Clamping: A high-power hydraulic cylinder drives the clamping arm to firmly secure the tire (preventing shake or displacement during cutting), ensuring operational stability and safety;
Powerful Cutting: Driven by hydraulic power, an ultra-heavy cutting disc (like an industrial “giant pair of scissors”) descends vertically, applying massive shearing force to cleanly and efficiently cut the tire into regular strips in one pass;
Unloading: After cutting, the clamping device releases automatically. The cut rubber strips slide out through the discharge port and can be directly fed into the subsequent tire shredder for further processing.
The entire process requires minimal manual intervention—it saves time and labor costs while ensuring clean, flat cut surfaces (preventing irregular edges from affecting subsequent shredding).
Core Performance Parameters of Tire Cutting Machines (Reference)
As key pretreatment equipment for large tires, its core parameters directly determine processing capacity. Taking mainstream models as an example:
Hydraulic System Pressure: Maximum operating pressure up to 207 bar (3000 PSI), meeting cutting needs for high-hardness full-steel tires;
Cutting Efficiency: Cutting time for a single large tire (5–8.2 feet in diameter) ≤ 5 minutes; hourly processing capacity of 10–15 tires;
Cutting Size: Can cut tires into regular strips 8–12 inches wide, matching the feeding requirements of downstream shredders;
Equipment Power: Main motor power of ~75 HP (≈55 kW), ensuring stable power output.
Core Features of Tire Cutting Machines: Why It’s a “Must-Have” for Large Tire Recycling
In large tire recycling, the efficiency of the pretreatment link directly determines the capacity of the entire production line. The 3 core features of tire cutting machines make them irreplaceable in this link:
Super Strong Shearing Force, Suitable for High-Hardness Tires The high-power hydraulic system provides sufficient shearing power—even high-hardness materials like full-steel radial tires can be cut easily, with no “unable to cut” or “blade jamming” issues;
High Durability, Low Maintenance Costs The cutting blade is made of AISI 4140 special alloy steel, offering excellent wear resistance and impact resistance. Its service life exceeds 1000 hours of cutting time, reducing the frequency and cost of blade replacement;
Comprehensive Safety Protection, Low Operational Risk Equipped with hydraulic locking + safety electronic control system (meeting ANSI safety standards), it monitors equipment operation in real time and effectively prevents misoperations (e.g., automatically pausing cutting if clamping is incomplete), ensuring the safety of operators and equipment.
Industrial Value of Tire Cutting Machines: The “Process Breaker” for Large Tire Recycling
For recycling enterprises handling large tires, the value of tire cutting machines goes far beyond “cutting tires”—it is the key to solving the “first major problem” of large tire recycling:
For the Production Line: Converting giant tires into regular strips avoids “jamming” or “blocking” when large tires enter shredders, improving the operation efficiency and stability of the entire recycling line;
For Cost Control: Automated cutting reduces labor costs for manual handling and auxiliary processing. It also reduces the load on shredders (eliminating the need to shred oversized materials), extending the service life of downstream equipment;
For Recycling Scope: Makes previously hard-to-recycle tires (like construction vehicle tires and giant agricultural tires) scalable resources, expanding the enterprise’s recycling business boundaries;
From “unwieldy giant scrap tires” to “regular rubber strips ready for shredding,” the tire cutting machine may seem like a “small front-end device”—but it is actually the “process breaker” of the large tire recycling industry chain. It solves the “entry-level problem” of large tire recycling, enabling large-scale, efficient recycling of high-difficulty scrap tires.
