Apron feeder is a kind of commonly used feeder equipment, divided into heavy, medium and light. The apron feeder is commonly used in ore dressing feeder.
Increasing productivity and upgrading downstream instrumentality need that the feed rate of upstream equipment is variable, and also the adjustable conveyance of title speed suggests that higher production capacity. to satisfy user requirements, we have a tendency to adopted induction motor speed regulation strategies supported the market conditions at that time. methodology of dominant the speed of asynchronous motor: On the control panel, we are able to see that the formula for the speed of AC induction motor is N = sixty * f1 / p * (1-s). in line with the higher than formula, there are many ways to regulate the speed of the asynchronous motor: one Pole-changing speed control The pole-changing speed management thusmetimes} divided into 4/6/8 poles. the amount of poles of the motor corresponds to the speed of the motor, so its application vary is tiny and subject to sure restrictions. a pair of Slip rate This speed control methodology is invalid as a result of the slip rate is simply too high and also the slip loss is massive at low speeds. Apron feeder is widely used in mining, concentrator, chemical, cement, building materials and other industries, widely used in the storage bin to crushing, transportation and other machinery for uniform continuous feeding.
If we decide this method to confirm its reliability, we have a tendency to usually choose the motor with the best motor power to calculate the motor power: for example, if the motor power is calculated as 45kW, we should always use a 55kW motor to calculate to confirm that the feed baffle is at low-speed won't manufacture deficient power. In addition, once this type of motor is employed in {an exceedingly|in a very} metal mine, the carbon brush of the connection is additional seemingly to be stained with iron powder, and a long tangency can cause an accident within the motor. three Frequency management of asynchronous motor to stay the ability issue of the excitation motor constant, we have a tendency to additionally expect to keep the trail unchanged by adjusting the frequency of the asynchronous motor. The higher than parameters have changed, the power has dropped, the torsion has dropped, and also the engine power can't be totally utilized, inflicting losses, thus if the frequency could be adjusted to stay t track constant, the track will stay unchanged normally. Frequency, the diameter of the voltage/frequency core should be specified. The voltage ought to amendment in proportion to the frequency. The feeding ring is a semi-continuous feeder, its power is low speed and high torque, and its speed management methodology is a typical constant torque speed control, which needs a frequency device to confirm that VI and FL change proportionately to ensure that the frequency changes with an equivalent overload capacity. . In Figure 10, the output torsion is that the largest and constant.
