Double Shaft Shredder Crusher Technical Specifications

Multiple models available for different capacity needs. Blades use 42CrMo alloy steel, HRC 52-56, impact toughness ≥78J/cm², meeting GB/T 3077-2024 and ASTM A29/A29M. Main frame uses Q345B steel.

Four Core Advantages of Double Shaft Shredder Crusher

Four operational strengths give this shredder its competitive edge in demanding applications.

Low-speed high-torque dual-shaft shear. Operating at just 9 to 15 r/min, the machine delivers continuous high torque with shear force evenly applied from both sides, exceeding the performance of single-shaft units.

Energy-efficient and intelligent. The equipment consumes 30% less energy than high-speed shredders at 28 to 35 kWh per ton. PLC auto-reverse handles overloads automatically with 97%+ success rate.

Repairable and safe blades. 42CrMo blades cost only 30% of replacement cost to repair. Thickness customizable from 25 to 100mm. Breakage rate 67% lower than single-shaft.

Effective sealing. Multi-layer seals block fine particles from bearings, extending average bearing life beyond 12,000 hours and reducing maintenance downtime.

Working Principle of Double Shaft Shredder Crusher

Dual shafts rotate in opposite directions at low speed. Interlocking cutting teeth on blade discs apply shear force from both sides simultaneously. Dual motors with dual reducers drive the system. Discharge size adjusts via blade thickness and cutter spacing. PLC system auto-reverses on overload or material bridging.

Applicable Materials for Double Shaft Shredder Crusher

From polymers and metals to wood, e-waste, and mixed refuse, this equipment handles a broad spectrum of materials.

Polymers. Plastic barrels, film, PET bottles, pipes, plus automobile and truck tires and rubber scrap. The dual-shaft design prevents jamming on fibrous or wrapping materials.

Metals. Steel, aluminum, copper, drums, and vehicle shells. The equipment compresses and tears light metals into irregular flakes for magnetic separation and smelting.

Wood and E-waste. Pallets, wood waste, branches, plus circuit boards, appliance shells, hard drives, and components. Nails in pallets won't damage blades. Denser blade configuration recommended for uniform e-waste output.

Other Waste. Municipal solid waste, industrial waste, medical waste, and mixed materials.

Double Shaft Shredder Crusher vs. Single-Shaft and Four-Shaft Shredders

Single-shaft shredders are lowest cost and handle regular solid materials but jam easily with fibrous or wrapping materials. Double Shaft Shredder Crusher is moderately priced, excels with fibrous and mixed waste, and offers a strong overall cost-performance balance. Four-shaft shredders produce highly uniform output for high-precision applications but cost 1.8 to 2.2 times more than dual-shaft units.

Key comparison data: Double Shaft Shredder Crusher achieves 22% higher tire throughput than single-shaft at equal power, with 67% lower blade breakage. Speeds: single-shaft 30-80 r/min, double-shaft 9-15 r/min, four-shaft 10-20 r/min. Power per ton: single-shaft 22-28 kWh, double-shaft 28-35 kWh, four-shaft 40-55 kWh. Blade replacement: single-shaft 120-200 hours, double-shaft 300-500 hours, four-shaft 400-700 hours.

For most solid waste reduction and recovery applications, the product delivers strong value.

Double Shaft Shredder Crusher Performance Data

The following performance data of Double Shaft Shredder Crusher is based on industry testing under various operating conditions.

DS1200 processes waste tires at 1.8 to 2.2 t/h with 30-50mm output. Same model processes plastic barrels at 2.5 to 3 t/h with better uniformity. DS1000 processes circuit boards at 0.8 to 1.2 t/h with sub-20mm output, notably improving metal separation. DS800 processes pallets at 1.5 to 1.8 t/h, reducing whole pallets to sub-50mm chips for biomass fuel.

A recycling line with Double Shaft Shredder Crusher achieves 20 to 25 tons daily, roughly 30% more efficient than single-shaft solutions.

Double Shaft Shredder Crusher Selection Guide

Selection depends on three factors: material type, capacity needs, and output requirements.

For hard materials like metal and rubber, choose thicker blades with wider spacing and motors above 37kW. For light materials like film, choose denser blades with slightly higher speed. For mixed waste, choose hydraulic feeding assist to improve feeding efficiency by about 20%.

DS600 suits small to medium stations processing under 10 tons daily. DS1000 and DS1200 suit medium enterprises processing 20 to 30 tons daily.

For sub-20mm output, choose tighter blade spacing or add fine crushing. For coarse output above 50mm, choose thicker blades with wider spacing to raise capacity by roughly 20%.

Testing 2 to 5kg of material samples before purchase is recommended. we offer free testing.

Frequently Asked Questions About Double Shaft Shredder Crusher
