Description:

Tire crusher (also called rubber crusher, tire shredder) is a kind of equipment that can crush waste tires into rubber pieces under normal temperature. It mainly consists of tire hoisting machines, power systems, crushing knife groups, screening institutions and so on.

Working principle：

The tire crusher features a horizontal structure with an integrated base and independent bearing supports, ensuring straightforward installation, commissioning, and long-term maintenance access.
Large waste rubber pieces and whole tires are fed into the primary crushing chamber. Crushing is performed by intermeshing cutters mounted on two parallel shafts that rotate at a controlled differential speed. The relative motion between the rotating cutters and the stationary counter-blades shears and tears the rubber material into smaller fragments.
Once crushed, the rubber pieces fall onto a rotary sizing screen. Fragments that meet the target size pass through the screen apertures and discharge onto a conveyor belt for collection. Oversized pieces are carried back into the crushing chamber by the rotating screen for secondary crushing until they reach the specified dimensions.
The cutter surfaces undergo specialized hardening treatment to achieve high hardness, structural rigidity, and excellent wear resistance. Power transmission follows a two-stage reduction system: the motor drives a pulley and belt arrangement, which feeds into a gearbox reducer, and finally drives both crushing shafts in synchronized rotation.

Features ：

Heavy-Duty Dual-Shaft Design — The intermeshing rotary and fixed blades are precision-engineered from high-grade alloy steel with advanced surface hardening, delivering superior wear resistance and extended service life even under continuous heavy-duty operation.

Intelligent Size Control System — The integrated rotary drum screen with automatic recirculation ensures consistent output particle size. Oversized fragments are automatically returned for secondary crushing, eliminating manual intervention and maximizing material utilization.

Energy-Efficient Power Transmission — The optimized two-stage reduction drive (motor → belt pulley → gearbox → dual shafts) minimizes energy loss and reduces operating costs while maintaining stable torque output across varying load conditions.

Modular & Flexible Configuration — Multiple feeding options (inclined conveyor or bucket elevator) and discharge solutions (rotary drum screen or star screen) allow full customization to match your facility layout, throughput requirements, and end-product specifications.

Low Noise & Stable Operation — The rigid integrated base and independent bearing supports effectively dampen vibration and noise, ensuring smooth, reliable performance with minimal maintenance downtime.

Wide Material Compatibility — Capable of processing whole tires, truck tires, radial tires, inner tubes, rubber shoes, and various waste rubber products — with optional steel wire removal for bead-reinforced tires.

Applications：

Tire crusher is a multifunctional equipment mainly used for crushing waste rubber and tires, including removing ring steel wires, crushing truck tires, radial tires, inner tubes, rubber shoes and other waste rubber products, meeting their feed particle size requirements. In the waste rubber recycling industry, it helps to rough process old rubber, reduce the impact load of crushers and shredders in recycled rubber plants, and improve crushing efficiency. In addition, the crusher can also serve as a pre-treatment device for fully automatic continuous pyrolysis equipment, processing waste tires and rubber into fuel oil, and shredding them into 30-50mm rubber blocks to improve pyrolysis efficiency. At the same time, it is also an important component of the rubber powder production line, used for producing rubber powder or rubber particles.
