SWECO introduces the MM4 Traveling Spray

SWECO, a business unit of M-I L.L.C., a world leader in separation technology, is pleased to introduce the MM4 Traveling Spray, an attachment that can continuously or intermittently wash screen mesh free of solids. Typical applications for the MM4 rectangular separator include dewatering cellulose fibers, plastic recycling, kaolin clay dewatering, starch production and general waste stream solids removal. In many of these applications, capacity is reduced due to screen blinding. SWECO developed the Traveling Spray to prevent this problem. The way the Traveling Spray System operates is a traveling bar, equipped with 21 spray nozzles, moves from side to side, spraying water directly onto the screen mesh to keep the screens clean and facilitate material conveyance. The bar reverses at the sidewalls and travels back over the screen for a continual cleaning process. The system is suspended from the stationary sump skid to avoid interference with the vibrating basket. It is equipped with a variable speed drive which allows the operator to optimize the screen de-blinding process while minimizing water usage. SWECO serves the chemical, food, minerals, pharmaceutical, paper and many other industries with a complete line of separation, sizing and milling equipment and a full selection of Aftermarket Parts and Screens.
