Silicon Bauxite beneficiation technology of de-
Drift, such as 4.1mA, then taking into account the servers put the regulation of signal and receiving 4.1mA 4mA feedback signal, will send a signal off the valve actuator, the actuator at a time limit has been and can not be shut . This case, the actuator motor is always in the rotation, the motor easy to burn, this phenomenon should be avoided. So tune lower limit, the need to adjust the signal transferred to 3.7-3.9mA to determine the location of the cam LS1. Similarly, when the adjustment of ceiling limit, the need to adjust the signal will be transferred to 20.1mA to determine the location of the cam LS2. Fourth, the implementation of fault and checks. (1) The actuator does not move, but the control module power and signal lights are bright. Check: power supply voltage is correct; motor is broken: ten-pin plug from the line from end to end is broken; motor, potentiometer, capacitor connection plugs are all good: A Comparative exchange method to determine the control module is good. (2) The actuator does not move, power lights and the lights are not bright. Check: the input signal is properly polar Majesty,[link widoczny dla zalogowanych], etc.; by contrast Huhuan method to determine the control module is good. (3) actuator motor,[link widoczny dla zalogowanych], fever, frequent stop working. Check: whether the matching valve to allow pressure within the rated range: if the actuator jam phenomenon; (4) rapidly heating the actuator motor,[link widoczny dla zalogowanych], shocks to crawl a short time to stop action. Check: 2V voltage range AC input control module test whether there is communication interference; signal lines and power lines are isolated; potentiometer and the potentiometer wiring is good; feedback component movements are normal. (5) moves the actuator was stepping,[link widoczny dla zalogowanych], crawling phenomenon of slow. Check: operator movement of technical equipment to signal the time is correct. (6) actuator position feedback signal is too large or too / J,. Check: (7) plus signal actuators open and close, limit switch does not stop. Check: the function selector switch control module is in the correct position: ( actuator action is not normal, but after the limit switch the motor does not stop action. Check: limit switch malfunction; limit switch wiring failure: Replace the control module to determine. (9) actuator belt off. Check: the actuator is damaged part of the internal drive stuck; Silicon Bauxite beneficiation mouth off completion of the study of new technology: Beijing General Research Institute of Mining and Metallurgy, Shandong Aluminum Corporation. View of the diasporic bauxite minerals naturally small size,[link widoczny dla zalogowanych], mosaic complex relationships with the living body embedded in the rich fabric coarser easily gangue minerals and the main characteristics of clay. The results of inheritance and development of bauxite beneficiation Select Is characterized by coarse grinding condition, after the grinding of mineral grain size classification to obtain the thickness of the two products, the products were fractionated by flotation sorting. FAST developed a collector BJ BJ 4222 and a 2132 high modifier. Al-Si ratio of 5.83 in the ore, the mineral rate of sperm obtained 83. O9%, concentrate Si ratio 12.61, alumina 90.39% recovery rate. Technical and economic indicators and research results at international level. Shandong Aluminum Corporation of new technology for alumina production system transformation, the annual sales income of 2.8 billion, the new profit 0_57 billion, 20.79% internal rate of return.
