In mining operations, the Feeder Breaker is specially developed and manufactured for open-pit mines. Its design concept and structural form are both the first of their kind in China. It is a heavy-duty continuous crushing equipment integrating functions of feeding, screening, crushing and conveying. The conveying part adopts heavy plates or chain plate structures, the screening part adopts the structure of static pre-screening + dynamic pre-screening, and the crushing part adopts hammer type or teeth roller type structures. The product has a simple structure, is lightweight, and has extremely strong crushing capacity for large blocks. Since its launch on the market, it has been highly favored by users.
Feeder Breaker Patent
Through the combination of long-term theory and practice, the performance of the Feeder Breaker and its long-term operational reliability have been fully verified through practical application; key details such as dynamic pre-screening, static pre-screening and conveyor box integration, protection devices for the drive chain, and intelligent implantation have been improved to the highest standards. It has obtained multiple national patent technologies, the first in China and a pioneering innovation!
Working Principle Of The Feeder Breaker
The material is conveyed by the scraper connected by circular chain links and moves horizontally in the conveyor box. When the horizontally moving scraper and the material pass through the rotating crushing teeth rollers in the crushing box, since the large pieces of material cannot pass through the specific space between the crushing teeth rollers and the scraper, the large pieces of material will be struck, squeezed, and stretched by the rotating teeth rollers until they are crushed. While the small pieces of material smaller than the discharge particle size requirement do not need to go through crushing and can pass through the crushing teeth rollers directly. Finally, the crushed materials are discharged through the discharge port of the crushing device.
By adjusting the frequency of the frequency converter and changing the rotational speed of the variable-frequency motor, the running speed of the scraper can be altered, which to a certain extent can regulate the processing capacity of the entire equipment; by adjusting the center height of the crushing tooth rollers, the particle size of the crushed output can be regulated to meet the different needs of customers.
Feeder Breaker Feature:
►The crushing particle size is large, with the maximum feed particle size reaching 2500mm, which solves the problem of crushing large pieces of materials in open-pit mines.
►It can achieve the process of screening first and then crushing, maximizing the finished rate of block coal in the open-pit mine and improving the economic benefits and value of the mining company.
►It adopts modular design and has diverse combination forms, meeting the different needs of different customers.
►The process flow is simple, achieving multi-functional equipment, with low equipment investment cost and fast construction period.
►It has a high degree of intelligence, featuring stall protection, chain break protection, three-phase current imbalance detection, and automatic adjustment of material flow, etc.
►The unloading height platform is lowered, the retaining wall height is reduced, which significantly reduces safety risks and minimizes civil engineering investment, making the relocation process more convenient.
