Application of the Hydrostatic Bearing Technology

Hongxing concentrator pilot has transformed 1 Φ2.7m × 3.6m ball mill and Φ3.6m × 4.0m ball mill, the smart ball mill hydrostatic bearing has the following characteristics: ① The specific mill, according to the load working conditions calculated by the computer to optimize the design of the bearing structure, and calculation to determine the matching parameters of the hydraulic pressure source, Lee Peng original tile ontology design and manufacture of the hydrostatic bearing, lower bearing cost of 25%. ② two of its hydraulic source filtering can guarantee long-term stable oil work, in particular, is a special oil return filter basket, very convenient to workers in the state of stopping the machine replacement and cleaning. The ③ shunt accuracy of 3% in the different load conditions, the oil film thickness for o.os ~~ 0 25 mm, the axial width of all attachment, is very uniform, the entire circumference of both the film. ④ End of the whole system by the automatic control of the programmer (PLC). System pressure, temperature, level, filter status indicators are real-time display of sensor and digital display instrument; the system can complete a working pump and standby pump automatically switches to the automatic adjustment of the oil temperature, fault display and alarm, emergency chain of parking and other functions, easy to operate, reliable operation. ⑤ The system also has a manual transmission in the ball mill operation state maintenance for the pump or forced circulation oil filter. Hydrostatic bearing has been trouble-free operation, the pilot was a success. Power consumption compared with the transformation of the former, the saving rate of 9.2%. The application has some promotional value. Red Star concentrator 23 sets of ball mill, the total drive power of 15 900 kW. If all of the hydrostatic bearing transformation can be carried out, it can save more than 700 million kW. H a year, nearly 300 million RMB; bearing similar to the wear-free operation, but also...
