Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mineral processing equipment, and in particular to a device for detecting the wear degree of a sand discharge nozzle of a cyclone in a mineral processing plant. Background Art
[0002] The cyclone grit nozzle is a critical component in mineral processing plant operations, and its wear directly impacts classification effectiveness and production efficiency. Existing methods for detecting grit nozzle wear rely on regular manual inspections. Because the nozzle is located within the grit chute, inspections require personnel to crawl into the confined space, making it difficult to maneuver. Furthermore, inspections can only be performed using an internal diameter caliper and then measuring the caliper with a ruler. Because the degree of wear varies across different angles of the nozzle, multiple measurements must be taken and the average calculated as the test data. This entire cyclone grit nozzle measurement process presents challenges such as low accuracy, high safety risks, and operational difficulties. Utility Model Content
