QF500C-12L Full-automatic Ball Milling System Technology Agreement
(mainframe constant power feed control , constant speed）
Introduction: QF500C-12L Full-automatic Ball Milling System use constant power to control the feed of mainframe with high control accuracy. Control system and field instrument use 485 communication with real-time display. The ball milling system use three-points thermometry, section water injection to keep temperature more precise and steady. Main unit adopts weighing way, lead ball is kept with same weight by PLC control , PLC touch screen with fully automatic control, timely displaying operation status & parameters of each unit, and automatically recording, as well as displaying alarming for malfunction and solving the problems. It has high precision control of lead ball quantity, negative-pressure, temperature and so on, and has stable physical & chemical index.
1. Equipment composition and main components configuration of the lead oxide production line :
2. Function of production line
A、 Application：
For lead oxide production,
B、 Technological process:
(1) Storage the lead granular in silo, the lead granular should be separate and 80% above of the lead granular should be shaped approximate cube, weight 90g±10g;
