Grain Coating Machines

Grain Coating Machines
for applying grain onto the resin coated web

PS-grain coaters are exclusively designed for the use in the coated abrasives industry.
Please let us know your problem definition. We would be pleased to quote you the right solution.

PS manufactures stationary gravity and electrostatic coating units, mobile units and double hopper units for a continuous non-stop production.

With our strewing machines all common sorts of grain and all common grit sizes can be applied. Optimized design allows short change over times for grain. Movable machine components allow short cleaning times of the strewing room. Change of strewing belt is possible within a few minutes without the need of any tools.
