· A duplex inlet and outlet ball mill pulverize system model is established by considering the effect of raw coal moisture on the dynamic characteristic of the mill. The EKF approach is employed to estimate and verify the model states, and an extended state space predictive controller is applied to the established model.
The raw coal is discharged when it is lifted to required height and then come to powder making system by double layer air lock valve. ... the explosion venting valve and nitrogen protection connector are set on hot wind inlet pipe of air swept coal mill and outlet pipe of coal wind.
Second, the ball mill maintenance and maintenance 1. Sealing of incoming and outgoing materials: Air leakage, leakage; wear of inlet and outlet ducts (wearing of cement discharge chute). 2. Wear and deformation of the inlet and outlet spiral barrels. 3. Check the main motor bearing temperature and check the large ring gear Harvard bolt. 4.
The profiles for double end feed/discharge mills are modified as per OEM's proposal to suit the high chrome metallurgy. The liners for double inlet/outlet mill are supplied in 24% Cr with 5660 Rc hardness. The modifiions and the alloy proposed have helped customers to:

Accuracy of the measurement of coal quantity feed into the boiler furnace has great influence on the combustion and coordinated control of power plant. According to the characteristics of double inlet and outlet mill pulverizing system, the method of calculating the amount of coal into furnace using the correlated variable was presented. On this basis, the coordinated control system was designed.

Coal dust lines and the expansion joints installed here require a special design to prevent the coal dust from settling and possibly igniting within the lines. Rectangular flue fabric compensator solutions has proved that the high quality standard for maintaining reliable expansion joints is dependent on selecting the right design and the best materials for the existing operating conditions.
• Inlet and outlet hoppers • Casing: single, double bottom, or side inlet for extraction from pits • Chain with blank and bent links or forged type with pressed links • Chain guide in Polyzene or manganese steel • Cups for collection of residual material • Overflow hatch with safety device • .
Airswept coal mill uses windsweeptype structure with a drying storehouse, making it has greater adaptability of coal with moisture. The grinding position has combined arrange layout of ladder liner, doubleladder liner and corrugated liner, which improves the grinding ability of the coal mill. Feeding device is oblique inlet shuttertype ...
