Robbins Continuous Conveyors have been used in various types of mines around the world, both operating behind TBMs and for other mine haulage applications. Robbins conveyors are durable and can handle irregular-sized muck loads that are common in drill & blast mining and other types of mining operations.
Robbins engineers design reliable conveyor systems regardless of whether we are delivering muck through a straight tunnel or a tunnel with multiple curves. Systems always include a main drive, an advancing tail piece, and a belt storage cassette, which are sufficient for many straight tunnels.
--The Robbins Company has the longest history of continuous conveyor manufacture amongst all TBM suppliers. Robbins was involved in supplying the first conveyor used behind a TBM during Pakistan’s Mangla Dam Tunnel Construction in 1963.
--Continuous conveyors contribute to high overall advance rates.
--Robbins conveyors can be designed to haul mega loads—it simply depends on the tunnel space and machine speed. Conveyors up to 1,100 Metric TPH have been provided, with systems of 1,800 Metric TPH or more possible.
--For longer systems, extensive monitoring can be provided to detect potential failures, rips, or fatigue in the belt. An integrated rip detection system combines electronic monitoring with video surveillance of discharge points to pinpoint longitudinal rips, tears, or deformations, and can save significantly on conveyor downtime.
--Robbins vertical conveyors are optimal for deep shafts. Vertical conveyors can be designed for shafts of 650 m depth or more.
--Robbins conveyors are optimal for small site footprints and small tunnel diameters. Conveyor systems have been provided for tunnels as small as 3 m in diameter. The smallest site area on which a conveyor was ever provided was 57 square meters.
--Robbins belt structure is more robust than its competitors and up to 33% heavier with heavy duty steel. Belt drives and takeups are also heavy duty, and built to last.
