Mining Machine : Vibrating Feeder Vibrating Feeder is a kind of linear direction feeding equipment.It is used to transfer the large size materials and granular materials from hopper to receiving device uniformly, periodically and continuously in the production flow and to feed materials into the crusher continuously and uniformly also to screen the materials in the sandstone production line. The vibrating feeder is widely used to match the crushing and sieving equipments in many industries including metallurgy, coal mine, mineral dressing, building material, chemical, grinding, etc. which will be generally installed in front of the primary crusher, conveys big blocks continuously and evenly while removing the dirt and impurities by screen bars. As necessary equipment, it can effectively control the feeding capacity to match with the capacity of the whole crushing plant. In the Sand-Stone production line, it can send materials to crusher evenly and continuously and at the same time, it can screen materials roughly. It can be used in these areas such as metallurgical industry, coal mining industry, mining-selecting, building, chemical and grinding industry, etc. Working principle of Vibrating Feeder: There are two eccentric shafts rotating at high speed at the same time from opposite directions, thus the strong centrifugal force is formed. The component forces of centrifugal force along the vibrating direction will always overlap each other, then counteract with that of vertical force from vibrating direction, then exciting force along single direction is formed to drive the feeder vibrate along straight line. When materials are fed into the feeder, they may be thrown up and move like para curve, then fall down. The materials will move forward on the slope surface of the feeder. Characteristics of Vibrating Feeder: Smooth vibration, reliable operation, long service life, low noise, low power consumption, easy to adjust, simple structure, easy to install, light weight, small volume, simple maintenance.
