How a Tripper Conveyor Works in Aggregate Processing

A tripper conveyor is a specialized bulk material handling system used in crushing/screening plants to distribute aggregates (sand, gravel, crushed stone) to multiple stockpile locations. It consists of a moving belt conveyor mounted on rails with a discharge mechanism (“tripper”) that laterally shifts to drop material at predetermined points.

Key Components

– Main Frame: Steel structure with rail tracks (typically 18-43kg/m)
– Drive Unit: 7.5-55kW motor with gear reducer (speed: 0.8-1.6m/s)
– Tripping Mechanism: Hydraulic or electric trolley system
– Discharge Chute: Wear-resistant steel (AR400 or Hardox 450)

Technical Parameters

Model Belt Width (mm) Capacity (t/h) Travel Length (m)
TCC-800 800 200-350 15-50
TCC-1200 1200 400-800 20-80
TCC-1400 1400 600-1000 30-100

Operation Principle

Material enters via the head pulley while the tripper carriage moves along the rails. When reaching designated stockpile positions, hydraulic cylinders tilt the discharge chute to offload aggregates. The system allows continuous feeding without stopping conveyor movement.

FAQ Section

Q: What’s the maximum incline angle?
A: Typically 15° for dry aggregates, reduced to 12° for wet materials.

Q: How to prevent material spillage?
A: Use high-side skirts (300mm+) and adjustable sealing strips.
