Finishing plant boosts production

The finishing plant is part of a £1.8m investment at the Derbyshire premises that has increased potential throughput by 70%.  As well as containers for the offshore sector, the company produces products for recycling, military and general waste applications ranging from 1m³ to 50m³ capacity.  The high-specification offshore products meet Lloyds Register of Shipping and Det Norske Veritas standards.

Working closely with Hodge Clemco, Mayfly used its in-house capabilities to construct a self-contained blast room for surface preparation within a new production building. In the blast-room (6.5m wide x 21m long x 5m high), Hodge Clemco installed a high-performance dust extraction and air replenishment system and a media recovery system that minimises abrasive usage.

The company also supplied three blast machines designed to maintain maximum blasting velocity, uniform abrasive distribution and high work rate over a long operating life.  Three Apollo 60CE air-fed helmets with high-performance air filtration from Hodge Clemco provide protection and good visibility for the operators.

Abrasive is automatically recovered by a system of screw conveyors running in steel troughs beneath the blast-room floor.  Spent media is fed into a cleaning system that removes oversize and undersize contaminants, before discharging acceptable material into a six-tonne storage hopper for further use by the three blast machines.

Within the painting area of the new building Hodge Clemco installed four open-fronted extraction chambers, each 3m wide x 1m deep x 3m high, which extract fumes and overspray.  High-quality filter media remove 99.5% of contaminants before exhaust air passes through ductwork to atmosphere.
