If your bulk material handling operation has specific concerns about environmental or governmental compliance, you’re likely preoccupied with issues caused by carryback. Material stuck to the belt affects housekeeping, belt tracking and especially dust control.

With some bulk materials, you may find that standard belt-cleaning systems just aren’t thorough enough. Belt-surface blemishes can trap material as well. Your compliance and safety concerns continue to grow, and unscheduled downtime becomes a major problem.

With these factors creating operational challenges, you need a solution that ensures safe and compliant production while keeping material flowing.

As your partner in better bulk material handling, the engineers at Benetech have already developed your efficient solution.

The Benetech Wash Box™

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

When the trapped material passes under both primary and secondary cleaners, it often later dislodges and creates dust and spillage. Equipped with high-pressure nozzles, the Benetech Wash Box uses water to soften the 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 washbox, rollers stabilize it while the nozzles gently spray it down and secondary scrapers clean it.

As the belt leaves the conveyor washbox, 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 to a decanting basin.

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

Conveyor Belt Wash System Components

The sum of Benetech’s system makes the right whole because it has the right parts. The conveyor washbox includes the following components to achieve 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.

Belt width (inches) 36″ 42″ 48″ 54″ 60″ 72″ 84″ 96″
Nozzles per manifold 7 8 9 11 12 13 15 16
Manifold on wash box 2 2 2 2 2 2 2 2
Total nozzles 14 16 18 22 24 26 30 32
Total flow (liter/minute) 54,6 62,4 70,2 85,8 93,6 101,4 117 124,8
Pressure (bar) 3 3 3 3 3 3 3 3


Four conveyor washbox rollers help support and stabilize the conveyor as it moves through the enclosure while also 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.

Dual Tensioners

The Benetech Wash Box features dual ROSTA tensioners for a constant torque and continuous contact pressure. The tensioners contribute to gentler belt handling, longer belt life and much lower maintenance. They also help dampen vibrations in the belt band.

Enclosed Piping

The feed-distribution system to manifolds is equipped with a maintenance valve and filter to remove any impurities.

Inspection Doors

Benetech installs your belt wash box with two of our heavy-duty, dust-tight Inspection Doors. The doors’ distinctive design provides safe and easy access for performing your preventive maintenance. The Inspection Doors also feature a deflector panel, grease fittings on pinned hinges, tough door seals, never-seize latches and heavy-duty handles.

Discharge Basin

The generated effluent drains safely through the discharge basin and is directed to the plant’s drainage system or to a decanting basin.
