Introduction
Vibrating feeder can put the bulk and granular materials from the storage bin in uniform, time, continuous into receiving device. It can be used to feed materials into crusher constantly in sand production line which can avoid blocking the receiving opening of crusher, meanwhile it can carries on the coarse screening for material,which is widely used in metallurgy, coal mine, mineral dressing, building materials, chemical, abrasive and other industries combining with crushing and screening equipment.

Vibrating Feeder Application
Vibrating feeder can be used in screen medium-grained and bulk materials before crushing.Vibrating feeder has the creative design of double-eccentric shaft exciter to ensure that the equipment can breathe large impact pressure that be generated by the falling bulk materials. It can put the bulk and granular materials from the storage bin in uniform, time, continuous into receiving device in sand production line,which can avoid stoping the receiving device because of uneven feeding materials can increase working life of the machine. The feeder has steel plate and grid two kinds of structures. Steel plate feeder completely and uniformly put materials into crusher equipment, it is widely used in sand production line. Grid feeder can screen all kinds of materials, it is an essential equipment during screening and crushing working,it is economic and rational to adapt this system.

Characteristics of Vibrating feeder
Small size, lightweight, simple structure, low cost, easy installation and maintenance, no rotary elements without lubrication .
2. Vibrating feeder applies to the principle of sympathetic vibration, and work under the critical state so that consumes less power.
3. It can get accurate date of feeding volume because of effectively controlling the material line.
This series of vibrating machine adopt silicon controlled rectifier half-ware rectifying circuit, so it's convenient to adjust feeding volume and realize the centralized and automatic control of production process.
As the material in the feeding is threw up constantly and go on forward-jumping movement following a parabole, there is a little wear to feeding trough.
