Broke Conveyors

Formerly, machine width broke conveyors were built with the multiple rubber belts because it is impossible to get rubber belts exceeding 6’ in width.  Each belt ran on its own pulleys with multiple sets of bearing, shafts, etc.  Not only is there a lot of maintenance on difficult to access equipment, but broke tends to get between belts and jam things up.

James Brinkley Company developed the single belt broke conveyor which utilizes a dryer felt provided by the mill for a belt.  This provides a single belt of machine width at low cost, eliminates multiple pulleys, shafts, bearings and jamming.  It works because the felt load is still light.

Broke conveyors of several hundred feet in length and over 30 feet in width are common.  Conveyor speeds up to 500 FPM are available.  While conveyors can be run faster than this, we believe that higher speeds are not safe for those maintaining the conveyor.

The heart of the James Brinkley Company broke conveyor is the air-operated auto-guide mechanism.  This mechanism adjusts the lagged guide pulley position to automatically and continuously control belt position.  Pulley adjustment is proportional to belt location.  A ceramic coated stainless steel palm rides the edge of the belt.  The palm controls a pneumatic valve which inflates and deflates two opposed air bellows.  These bellows adjust position of a sliding roller-mounted guide bearing support on one end of the guide pulley.  The other end bearing is mounted in a standard adjustable take-up.  This continuous proportional adjustment system provides excellent belt training control.

       

Existing multi-belt broke conveyors can be refitted to single belt design.  The James Brinkley Company specializes in difficult applications.
