How to Solve the Problems of Apron Feeder Material Leakage and Bulk Material Recovery

Apron feeder is a kind of transfort equipment that driven by chain, which widely used for mining, metallurgy, construction, coal and environment protection and other industries. It is one of the best short distance continuous and uniform feeding equipment , the advantages is large feeding capacity, high bearing torque.
heavy duty apron feeder supplier
The apron feeder drives the reducer through the motor, drives the conveying trough plate through the sprocket shaft, and the conveying trough plate carries the material, finally achieving the purpose of conveying the material.
Apron feeder can be adjusted to various environment, can work in outdoor, moisture, dust and other harsh environment work reliably, but after years of actual use show that work under the bad environment in the bottom of the device will produce a certain amount of dust material leakage, leakage is not easy to clean, under normal yield loss, can cause certain serious hinders the operation of the equipment, so under this situation should handle dust material leakage problem is more urgent. Usually the way to deal with leakage is to raise the bottom foundation of the plate feeder, can be manually cleaned when the equipment is stopped, which can save costs, but the workload of the workers is larger, the efficiency is low, the equipment needs to stop running when processing leakage.
With the continuous development of mining, metallurgy, coal and other industries, the demand for production automation is constantly increasing, to ensure the continuity of the production process, reasonable reduction of the workload of workers, has become the trend of industry development.Through many years of design and production experience, this article puts forward some more practical methods that can avoid manual cleaning, and can deal with the problem of apron feeder material leakage and bulk material recovery.
For the occasion when the material humidity viscosity is relatively large, the material is easy to bond to the groove plate, the groove plate will remain on it after turning back, the material will fall to the lower part of the feeding machine when empty, it is not easy to clean up, at this time can adopt the method of adding sweeper at the bottom to deal with the leakage of material. Add a feeding chute under the front part of the feeder frame, and the scraped material will slide down the chute to the crusher or belt machine.This method is more suitable for material humidity viscosity occasions; For dry or dust more occasions, the effect is poor, and the swabbing pig needs to be replaced frequently.
These solutions have a certain of limition. According to the market requirement and continuous improvement of product technology, there are two effective and widely used methods, which can solve the problem of dust leakage and material leakage, and realize the automatic cleaning of dust leakage without manual operation.
Taking the Inner Mongolia Mining company apron feeder project as an example, according to the actually layout situation, a 2400*12000 heavy duty apron feeder be designed. The production process to produce the leakage of automatic cleaning according to the requirements of customer. Through analysis and research, the original heavy duty apron feeder structure design, using hierarchical structure, the upper structure for heavy duty apron feeder, the lower structure for trough chain conveyor. Upper plate feeder for conveying materials, the lower layer scraper conveyor recycling scattered materials, in use may not often start, depending on the material situation.Upper and lower mechanism adopts independent drive device, left and right separated arrangement, can operate independently.
The upper plate feeder adopts the form of single arc lap, without material leakage, and the maximum conveying capacity can reach 1000t and h. The lower scraper conveyor adopts the semi-closed box structure, in which the bulk materials are dropped into, automatically recycled to the lower funnel through the scraper, and transported to the material field through the belt conveyor.
