Ajax Equipment Assists HSL Dust Explosion Research

Solids handling equipment manufacturer, Ajax Equipment has supplied the Health and Safety Laboratory (HSL) with a screw feeder and hopper for research into dust explosions in small vessels. The single variable screw feeder is being used to feed dust into a dust collector to assess the explosion risk.

HSL, an agency of the Health and Safety Executive (HSE), is undertaking the project to establish dust explosion venting requirements in vessels having volumes of less than 0.5m3.

Ajax screw feeder and hopper

The Ajax steep walled hopper and variable pitch screw are designed to offer best flow and feed reliability for a range of dust materials, ensuring the 100mm diameter screw is completely filled when feeding the dust powder into a cyclone for explosion testing.

The HSL project on the risk of dust explosions in small vessels (less than 5m3) is expected to be completed in March 2012.
