Sand and gravel production line, special circular vibrating screen for quarry
LZZG mine vibrating screen has the characteristics of reliable structure, strong excitation force, high screening efficiency, low vibration noise, sturdiness and durability, convenient maintenance, safe use, etc., and low output and energy consumption. It is highly praised by users in the Philippines, Malaysia, Vietnam, etc. The vibrating screen is suitable for a wide range of materials: iron ore, copper ore, gold ore, limestone, quartzite, ceramic soil, refractory clay, marble, granite, salt mines, etc.
The sand-gravel vibrating screen works by using the reciprocating vibration generated by the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce plane whirling vibration, while the lower rotating weight causes the screen surface to produce cone-shaped rotary vibration. The combined effect of the vibrator causes the screen surface to produce multi-rotating vibration.
Its vibration trajectory is a complicated spatial curve. The curve is projected as a circle on the horizontal plane, and projected as an ellipse on the vertical plane. The amplitude can be changed by adjusting the excitation force of the upper and lower rotating weights. Adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the screen surface movement trajectory and change the movement trajectory of the material on the screen surface.
The sand-gravel vibrating screen can sieve the material into various sizes, and you can get fine sand, medium sand, coarse sand, gravel and other products. The lzzg vibrating screen has the advantages of low price, reliable product quality, and perfect after-sales service. Welcome to consult and negotiate.
