REQUEST QUOTATION

The Repulp wet sizing screen is the ideal machine for the production of a clean oversize material free of fines or undersize particles. The Repulp screen is equipped with spray nozzles directed at one or more rubber-lined repulping or wash troughs. Highly efficient wet sizing and maximum removal of fines is accomplished by repulping and screening the material multiple times as it moves down the length of the screen surface. Spray water directed at the screen surface would result in accelerated wear and could also force oversize particles through the openings.

In fine wet sizing, undersize particles are transported through the screen openings by the fluid, normally water. Once all the water has passed through the screen surface, no more sizing takes place. Any remaining fines simply adhere to the oversize particles. The multiple repulping and rescreening steps possible with the repulp screen maximize the removal of fine particles. Multiple separation sizes or cut points are also possible by using a Repulp screen equipped with a split undersize hopper. A finer separation is made first, followed by a coarser separation.
