Adjusting the phase angles of the upper and lower ends can change the movement track of the material on the screen surface. According to the shape structure, some customers call it a circular sieve, vertical and inclined three-dimensional motion, and then transmit this motion to the screen surface. From the material, the standard type vibrating screen and the ordinary type vibrating screen are used. The standard part and the material contact part are made of 304 stainless steel, the base is made of carbon steel, the common type is made of carbon steel, and the square sieve machine is The lower side of the sieve body is very inconvenient to replace, and it is convenient to replace the sieve plate because there is no obstruction above the sieve body.
The inclination angle a of the sieve body can be large, and various types of sieve plates can be applied. When the screening effect is not required, the treatment amount can be increased, and the dropping hopper is small, but the material saved is small. The square sieving machine is recommended to be vibrating. The hot ore vibrating screen is high. The vibrator is easy to maintain underneath, which avoids the square sifter directly exposed to hot air and prolongs the use time of the exciter. The device voltage space vector pulse width modulation actually corresponds to the three-phase voltage source inverter in the permanent magnet synchronous motor. This control method can generate a sinusoidal current with a small waveform distortion of the mutual difference 120 in the customized coil.
