BRD / BRDS Double Shaft Shredder
Factory-built double shaft shredders for bulky waste, plastics, e-waste, light metal, tires, paper mill rejects, biomass, and mixed industrial waste. Share your material, feed size, output target, and capacity requirement for model selection and quotation.
Low-speed high-torque shredding, strong material grabbing, and BRD / BRDS configurations for front-end volume reduction before sorting, recycling, or disposal.
Machine Selection
The double shaft shredder is usually the first size-reduction stage for bulky or mixed material. BRD is selected for lighter-duty pre-shredding and compact recycling lines. BRDS is selected for larger feed size, tougher waste, higher impact load, and longer working hours.
Standard configuration
Recommended for compact pre-shredding projects where material is bulky but the operating load is moderate, such as plastic containers, packaging waste, e-waste, light metal, medical waste, and selected industrial scrap.
Heavy-duty configuration
Recommended for larger feed size, tougher material, continuous facility operation, and higher-impact recycling or waste treatment lines. Dual-drive heavy-duty configurations improve torque delivery and load resistance.
Material Match
A double shaft shredder is usually selected when feeding, grabbing force, and primary volume reduction matter more than fine output control. Material photos, videos, maximum feed size, hard contaminants, bulk density, and working hours help confirm whether BRD or BRDS is suitable.

Core Structure
A shredder should be evaluated as a complete working system. Cutter material, feeding method, screen or discharge design, overload protection, and gearbox drive all affect output stability, maintenance frequency, and long-term operation.
Cutter material, blade thickness, and tooth profile are selected according to waste type, impact load, wear condition, and output goal.
High-strength main shafts are designed to transfer torque steadily under bulky, mixed, and uneven feeding conditions.
Fixed knives on both sides of the chamber help improve shearing action, reduce wrapping, and support service access during maintenance.
BRDS heavy-duty configurations can use planetary gearboxes for stronger torque transmission, shock resistance, and demanding operating loads.
PLC control supports automatic overload detection and reverse logic to reduce jamming and manual intervention during uneven feeding.
Motor, coupling, gearbox, and frame support are configured together to match material load, working hours, and site operation requirements.

FAQ
A double shaft shredder is usually selected for bulky, irregular, or mixed material where strong grabbing force and primary volume reduction are more important than fine output control.
BRD is the standard compact double shaft configuration for lighter-duty pre-shredding. BRDS is the heavy-duty version with dual motors, planetary gearboxes, stronger shaft structure, and better suitability for larger, tougher, or continuous waste treatment applications.
Mixed waste can be processed, but the configuration should be selected according to the main material type, feed size, hard contaminants, bulk density, output goal, and operating hours.
A double shaft shredder mainly performs primary tearing, shearing, and volume reduction. Output size is influenced by blade width, tooth profile, speed, material condition, and discharge control, but it is not as screen-controlled as a single shaft shredder.
Very hard solid steel parts, stones, concrete, explosive or pressurized items, and materials with unknown hazardous contaminants should be evaluated before feeding. Photos and videos help us identify risks before quotation.
Please provide material photos or videos, maximum feeding size, main material composition, hard contaminants, required capacity, target output range, working hours, and downstream process such as sorting, separation, baling, RDF preparation, or further shredding.
