Static Elimination

Static Elimination in Gravimetric Blenders

Gravimetric blenders and hopper loaders often have optical level switches which become contaminated by dust or fines in the granulated material which sticks to the window through static charges. This blocks the window and prevents proper level control which may result in either an intermittent or a continuous feed into the moulding machine.

Arrowquint have designed a small (8mm dia) flexible electrode which can be readily inserted into a blender or hopper loader to blow low pressure ionised air into the granulate around the level switch, eliminating the static charges and preventing the contamination.
