Bag Breaker: Difference between revisions

Revision as of 11:56, 28 September 2021

A Bag Breaker is an automated opening machine that operate at the beginning of MRFs and release the contents contained in bagged waste into the downstream plant at the required throughput rate. Bagged material is fed into a Bag Breaker at an evenly metered flow rate and is split open by blades on counter-rotating drums without damaging the waste^[1]. Bags of all sizes can be split, and they are left in one or two pieces for easy removal via a series of crowder arms^[2]. Conveyors both load the bags and then unload the split material for further processing. The hooper box can be built to match the throughput of the MRF and so the Bag Breaker can also perform storage and metering functions to help free up time for the grab/shovel loader downstream^[3].

Applications

MRFs
PRFs
Material flow control
Bag opening
Feeding^[1]

Benefits

Higher processing capacity than manual sorting
Low maintenance and operational costs
Easy to retrofit into existing facilities
Does not damage bagged contents
Empty bags are torn to large pieces rather than shredded for easy removal
Eliminates the hazard of manual bag opening^[3]

The Process

Bagged waste is fed into the Bag Breaker via a conveyor at an evenly metered flow rate
The blades on large counter-rotating drums cut open the bags without damaging the contents
The waste falls from the bottom of the machine
A belt conveyor transports the recyclable material away from the machine for further processing downstream^[3]
