Case of Conveyor Belt Heavy Duty

Case Study: Heavy-Duty Aggregate Conveyor System for Sand & Gravel Quarry

CAFU Machinery designed and installed a rugged and durable gravel conveyor system for a construction materials producer, including: main conveyor belt, distribution belt conveyor, aggregate separation silos, and silo material discharge system. This system increased material handling efficiency by 35%. At its core is the heavy-duty aggregate conveyor, featuring:

• Belt Width: 1,000mm; Type: NN200-5×(4.5+1.5)-B1000

• Length: 49m with 15° incline

• Capacity: 600 tons

• Speed: 2.5 m/s

Engineered for abrasive environments, this conveyor belt heavy duty solution incorporates:

• Impact-resistant idlers (Ø159mm) with 50,000-hour L10 bearing life

• 8mm thick NM400 wear liners at loading zones

• VFD-controlled drives for seamless speed adjustment (1.5–3.0 m/s)

Conventional configurations include: active and passive drum assemblies, rubber-coated sheets (replaceable); drop-weight drum assembly; drop-weight tensioning device; head sweeper; tail sweeper; rain cover; emergency stop for pulling lines, etc.
