If compliance is a concern at your plant, Benetech has your efficient solution.

The Benetech Wash Box is a secondary conveyor belt–cleaning system for eliminating any carryback that remains on the belt. The Wash Box is ideal for systems conveying material that is hard to remove with typical belt-cleaning systems.

The conveyor wash box is equally effective with belt-surface blemishes that trap material. Trapped material passes under both primary and secondary cleaners and, after later dislodging, can create dust and spillage problems. Using water for belt-cleaning softens the trapped material so it can be properly removed and discarded.

The belt wash box is mounted on the return side of the belt, where secondary cleaners are typically placed. When the conveyor belt enters the enclosed box, rollers stabilize it while the nozzles gently spray it down and secondary scrapers clean it.

As the belt leaves the conveyor wash box, the rollers remove the excess water and dry the belt. The excess water and residue are then washed away and drained through the enclosure’s discharge basins to the plant’s drainage system or a decanting basin.

Combined with your primary cleaners, the Benetech Wash Box ensures complete, compliant cleaning for your application or material.

Benetech’s conveyor belt wash system includes the following to achieve a cleaner, safer, and more efficient production for your bulk material handling.

Spray Nozzle Bars

Spray nozzles moisten the carryback for much easier removal of residue from the belt by the scrapers. The spray bars are sized to suit the width of your belt.

Four conveyor wash box rollers help support and stabilize the conveyor as it moves through the enclosure while removing the water and drying the belt as it exits.

Secondary Belt Cleaners

Two sets of Benetech’s secondary cleaners guarantee the most efficient system performance.
