The BS-LXJQ series automatic ball adding machine is an intelligent device designed for the automatic addition of steel balls. When the ball hopper contains balls and conditions for addition are met, the main motor starts automatically. It uses claws installed on a drum to randomly pick steel balls from the hopper, with non-contact detection performed by a photoelectric detector. The system utilizes a programmable logic controller (PLC) for intelligent identification and control, enabling automatic ball addition to ball mills. This machine features smooth ball delivery, accurate counting, and functionalities like ball absence alarms and shortage displays. It is suitable for automatic ball addition in various stages of mineral processing, ensuring continuous, stable, timed, and quantitative ball addition, effectively reducing ball consumption and improving grinding efficiency.
