AI Technical Summary

Technical Problem

Traditional rotor sand mixers are prone to adhesive buildup at the discharge port, leading to frequent blockages that affect production efficiency and product quality.

Method used

It adopts an anti-sticking unloading structure, which ensures quantitative material discharge and cleaning of sticky sand through the intermittent rotation of the arc-shaped unloading plate and the differential speed movement of the scraper. This includes the cooperation of the unloading impeller, scraper and gear transmission components to achieve precise coordination between unloading and cleaning.

Benefits of technology

It effectively reduced the blockage rate of the discharge port, ensured the uniformity of casting filling and production continuity, and improved production efficiency and product quality.
