Screw auger compactors can double your tonnages, halve transport costs and cut maintenance bills when compared to conventional compactors. By deforming the waste before pushing it into the container, without shredding it, a screw (auger) compactor will maximize the space and increase the density. Up to 100% higher tonnages but typically 60% higher are not uncommon.
Compare this with conventional compactors which have a flat plate which pushes waste into the container. Compaction does not take place until the container is nearly full.
Many waste contractors are improving their competitiveness and winning business using screw compactors by increasing payloads, particularly for DMR (dry mixed recyclables). The customer pays less in transport and the operator runs a more efficient business. The higher tonnages allow them to increase turnover without increasing the size of their fleet.
Material drag-back seriously affects the efficiency of conventional compactors with a flat press plate (the exception being the Bergmann portable compactors with the 'throw over blade': see the link here). The material slides back under and round the press plate eventually jamming the cylinders and stopping the press plate from moving unless it is cleaned out regularly. Screw auger compactors have no space behind the press plate as the screw is driven with a drive chain.
Hydraulic compactors can be heavy on maintenance: they need oil changes and new filters every year, oil leaks are common even on the best makes due to the system being constantly under pressure and you pay for this.
Screw auger compactors are electro-mechanical: no hydraulics. Maintenance routines involve safety checks, greasing and tightening the drive chain: easily done by in-house engineers or fitters and much quicker.
These reasons alone would make choosing a screw auger compactor over a hydraulic static compactor a no-brainer, but there's one more: they cost the same or less. So with pressure on costs ever present, investigate a screw auger compactor as the better solution for your business.
