ZSW400 Model Vibration Bar Feeder Machine For Limestone

Description

ZSW400 Model Vibration Bar Feeder Machine For Limestone is designed based on the principle of exciting force generated by two eccentric shafts. It is mainly used for continuous and even feeding before primary crushing. Besides feeding, at the same time, it works as pre-screening. The pre-setting gap between grizzly bars avoid unnecessary power consumption of the following crushers, which improves the crushing efficiency .

Advantages

• The cascade bar has large drop difference, not easy to block material, fast feeding, with good pre-screening effect
• It is optional to add the extra high for side plate and extra liner .It is optional to change whole plate and steel plate with drilled-holes instead of grizzly bars in the pre-screening part , so it can be used in different working conditions.
• Frequency conversion controller can be used to adjust the frequency, easy to control the first section crusher feed quantity
• Thin oil lubrication structure; after the first filling, the oil will be replaced at the regular period;
• The feeding for the primary crushing can be controlled by adjusting power speed.

Working Principle

The exciter works as the vibration source of the vibrating feeder which is composed of two eccentric shafts (driving shaft and driven shaft) and gears. The electromotor drives the driving shaft to rotate at high speed, the gear of the driving shaft engages with the driven shaft, and then the two shafts rotate together in the reverse direction that make the trough body moving forward the material continuously. When the material moves along the grizzly bar, the material that is smaller than the screen hole will drop down the gap between grizzly bar, thus realizing classifying.
