The Maintenance Of The Vibrating Feeder

Vibrating feeder also named Vibratory feeder, Vibrating grizzly feeder

, Feed grizzly, and Ore vibrating feeder. Vibrating Feeder is a kind of linear direction feeding equipment. It features smooth vibrating, reliable operation, long service life and being suitable for feeding. They are widely used in mining, building-material, silicate and chemical industry in the crushing and screening plants. In the Sand-Stone production line, a vibrating feeder 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.

In vibrating feeder, the hopper scoop the materials sent in from the feed inlet by its own. If the location of the feed inlet is too low, most of the materials will enter in to the engine base before the hopper could scoop the materials, resulting in the failure of hopper scooping materials. Thus the materials will easily become a massive, and then cause deformation and detachment of the hopper. When this phenomenon occurs, workers should adjust the location of the feed inlet. In addition they can also change the materials of the hopper, and select high-quality materials to make the hopper. As the load components of the vibrating feeder (vibrating screen), the hopper requires relatively higher for the materials, so the installation should try to use higher strength material. 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.

Before starting the machine, workers must clear the accumulated materials within the base, otherwise it would cause the phenomenon of downtime. If workers start the machine after outage or downtime, without clearing the accumulated materials, the hopper would probably rapture or fall off. Therefore between shutdown and boot, it is essential to clear the accumulating material within the base. In addition, the connection the hopper and the hopper tie should also be regularly checked to make sure its firmness. Once finding the problem, regardless it is screws loosening and fall off or hopper skew and damage, it should be promptly repaired or replaced, as a preventive measure. Hopper tear should also be avoided in hopper operations, which would be caused by deviation of the hopper tie and detachment of the hopper. If workers discover this phenomenon, they must timely rind out the reason and remedy of the trouble. Moreover, the materials mixed with the foreign body of sharp edges should be avoided, because they could possibly crack the hopper tie. Therefore, during production process, the vibrating feeder should be installed mounted steel mesh or magnet on the feed inlet to avoid large piece of foreign matter falling into the base.
