Quieter approach to surface preparation

The accumulator bodies are manufactured from solid carbon and stainless steel billets, which are bored out to required dimensions before being painted and having the internal mechanisms installed. Cylinders range from 10 to 400L capacity and weigh up to 2t.

The new blast-room is 3m wide x 2.5m high x 6m long. Walls and roof are double-skin prefabricated steel panels filled with mineral wool slab which reduces noise levels outside the room. Walls and doors are lined with shot-blast curtains, and the floor is steel plate.

Media is projected by a 2452 SGV blasting machine via a tungsten-carbide-lined nozzle, which is designed to maintain maximum blasting velocity, uniform abrasive distribution and high work-rate over a long operating life.  Air inlet ducts and exhaust air outlets in the chamber ensure highly effective cross-draught ventilation in order to provide good visibility for operators.

Abrasive is recovered for re-use by means of a pneumatic suction filter unit linked to a sweep-in hopper in the floor of the blast room.  A vacuum silo receives all spent media, dust and debris from the floor hopper, separates out re-usable abrasive and places it into a storage hopper from where it automatically re-fills the blast machine.  The system is adjustable to allow for different types of abrasive.

Hodge Clemco also supplied a protective suit and an Apollo 600CE helmet with several advanced features for operator safety and comfort.
