Model HS

WHAT IS IT? The Model HS is a helical shaped stand alone brush assembly for use on conveyor belts to remove excess buildup and material carryback. The brush can be mounted and driven using various methods, including from the head pulley using a sheave/pulley & belt arrangement. In addition to cleaning conveyor belts, the Model HS has been used to clean sawdust from plywood sheeting, remove excess fiber from fiberglass boards, remove coffee fines from roaster drums, and excess concrete from newly formed concrete bricks and blocks.

WHY IS IT NECESSARY? The Model HS allows the user to customize the mounting and drive arrangement to accommodate confined spaces or special drive requirements.
