Dust-Sealed and Safe Sliding Beds

Maintenance at solid bulk transfer points can often be problematic: idlers that stop turning, ineffective skirts that wear unevenly and belts becoming misaligned. The Brunone SPARET EX slider belt is a simple solution for correcting these problems. 


The SPARET EX is a low tonnage slider bed that can replace the idlers located under transfer points to improve dust sealing and safety. During installation, there is no need to dismantle your skirtboards or rebuild your transfer point, simply remove the idlers in question and secure the SPARET EX in their place.

Carrying out maintenance on unequal troughing (picking) idlers under fine chutes is often challenging, given the difficulty in keeping the belt centred and ensuring the skirts are properly sealed. If you have or are thinking of installing a conveyor with unequal troughing idlers (picking idlers) under a screen, the SPARET EXP is the perfect solution for reducing maintenance and optimizing dust sealing of your conveyor.

The SPARET EXP is a slider bed for under-screen applications with a very wide belt. It is equipped with a system of flexible self-adjusting rubber skirts that provide optimal sealing with minimal maintenance.

SPARET EXP advantages:

  • Sleek design

  • Replaces all picking idlers for under-screen conveyors
  • Equipped with skirts and skirtboards
  • Optimizes dust sealing at chute transfer points by creating a linear seal between the belt and skirts
  • Improves safety

  • Galvanized steel chassis 
  • Ultra-high density polymer slider bars
  • Adjustable troughing angle
  • Available in lengths of 10′ (3 m) or more
