Washbox belt cleaner removes difficult carryback have installed the system are reported to have drastically reduced dust and spill- age from carryback, leading to a safer workplace and longer belt life with con- siderably less downtime.

US-based Martin Engineering has intro- duced a secondary cleaning system that removes nearly all of the carryback left on a conveyor belt, including adhesive materi- als and fines lodged in surface divots and valleys. The Martin® Washbox™ cleaning sys- tem combines water spray and secondary cleaning blades in an enclosed and self- contained unit, draining residue safely away from the work area. Operators who

washed by spray bars equipped with 10 to 30 nozzles delivering 0,34 to 4,14 bar of pressure, using 20 to 204 litres/min of potable or non-potable water. The belt is then scraped clean by a polyurethane blade and/or a urethane squeegee blade, set on a tensioner for a tight and consistent blade-to-belt seal. Residue drains safely through an outlet funnel below the box, which can lead to a disposal unit or a settling pond/vessel for introduction of material back into the process. Built for heavy to medium duty appli- cations, the Dual Cleaner System is equipped with three rollers, four spray bars, two Martin® inspection doors and two polyurethane secondary cleaners. Recommended for use behind a primary pre-cleaner on the face of the head pulley, the colour-coded, high-performance ure- thane secondary cleaners can be specified for acidic or high-temperature materials. The cleaner system can be speci- fied from 762 to 1 524 mm in length and 1 129 to 1 350 mm in height, and fits on most conveyor frames by adding approxi- mately 432 mm to belt widths of 457 to 2 133,6 mm. The Single Cleaner System houses a roller, a secondary blade and a spray bar, which are accessed by an inspection door housed on either side of the enclosure. Intended for tight-fitting spaces on light to medium duty applications, the compact unit is 381 mm long and can be specified from 864 to 1 072 mm in height. The total width of the unit can be determined by adding 432 mm to the belt width of 457 to 1 219 mm. Martin Engineering, tel (+27 13) 656-5135, website: www.martin-eng.co.za

“We design systems to eliminate nearly all carryback issues faced by every indus- try we serve,” said Dan Marshall, Product Engineer at Martin Engineering. “After extensive before and after testing, we developed the washbox to complement our standard products in some appli- cations to further improve the life of the belts, idlers, pulleys and clean- ing blades.” Available in two configura- tions, a Dual Cleaner System and a Single Cleaner System, the units are mounted on the conveyor frame directly after the return idler to ensure belt alignment throughout the clean- ing process and to allow proper time for moisture evaporation on the return trip. Passing through a powder-coated steel box with top rollers, the belt is gently selected North as a regional distributor in late-2014, due to its proven track record and excellent reputation in the industry. North’s Johannesburg and Durban branches currently stock the full range of Brady products. “We are currently negotiat- ing minimum stock orders and levels for a number of products in all North branches. North and Brady are a good match, as both companies uphold the same values, and there is a mutual understanding as to how each operates,”Morais Neves adds.
