Title: Particle collection system

Abstract: A particle collector for intercepting and collecting small particles dislodged during grinding operations utilizes a vacuum unit to trap particles within a collection bag. Uniquely formed intake nozzles provide effective particle pickup for both bench-type and hand-held grinding units. The nozzles may be interchanged without requiring the use of tools, and the collector may thus be conveniently switched from a bench-type grinder to a hand-held grinder. The vacuum source is portable and housed in a cabinet uniquely designed for quiet operation and even airflow. Particles are collected in a reusable bag and may be processed to recover precious substances. The nozzle designed for use with bench-type grinders may be horizontally or vertically positioned, as required by work space limitations.
