Traditional sand and gravel, and mineral crushing production lines usually adopt a layout where the feeding, screening, and crushing equipment are separately arranged. This not only makes the entire process flow lengthy and the construction cost high, but also large pieces and frozen adhesives are prone to cause blockage and stoppage of the machine. However, the Feeder Breaker overcomes the drawbacks of the separate layout by integrating the conveying, pre-sieving, and crushing functions into a single unit. The materials can pass continuously at the same level, completing the entire process of feeding, sorting, and crushing in one go.
What Is a Feeder Breaker?
The feeder breaker integrates three functions - conveying, pre-sieving, and crushing - into a single unit.
- Materials are continuously conveyed, sieved, and crushed along the same horizontal channel, eliminating the need for multiple transfers or uneven feeding through different levels.
- This equipment is widely used in industries such as mining, metallurgy, construction materials, and coal. It can be adapted to various open-pit mining operations and also meet the requirements of underground production conditions.
- The feeder breaker is mainly installed below a bin with a certain pressure and a funnel. It uniformly and continuously feeds, sieves, and crushes various large-density blocky materials over a short distance. It can complete heavy tasks in harsh environments and has a high degree of adaptability to changes in material particle size, temperature, viscosity, frost, rain, snow, or frozen materials. The feeding volume is uniform, accurate, and reliable. The machine can be installed horizontally or at an angle, with the maximum upward inclination angle of 15°.
- It has obtained multiple national patent technologies. It is the first of its kind in China and a pioneering product!
Working Principle Of Feeder Breaker
The open chute (storage bin) serves as the load-bearing component for coal, gangue or other materials, and the scraper is fixed on the chain (forming the scraper chain) as the traction component. When the head drive device is activated, it drives the sprocket on the head shaft to rotate, causing the scraper chain to operate in a circular manner and move the materials along the chute (storage bin), until it reaches the head section for unloading. The scraper chain performs a continuous closed-loop motion around the sprocket, completing the material transportation.
Feeder Breaker Structure
The feeder breaker is mainly composed of the conveying part (conveying drive device, conveying box, conveying chain & scraper, conveying tension device), the crushing part (crushing drive device, crushing tooth roller, crushing box), electrical control, and automatic lubrication (optional).
What Are The Advantages Of The Feeder Breaker?
01/ Lower Infrastructure Costs
The Feeder Breaker adopts an integrated whole-machine design for horizontal material flow crushing. It eliminates the traditional multi-machine, separate vertical material flow scheme. This design reduces equipment procurement costs and construction foundation investment, significantly cutting down infrastructure expenses.
02/ Low-Noise And Environmentally Friendly
The sliding scraper delivers materials smoothly, is shock-resistant, and operates without noise; the fully enclosed casing prevents dust from spilling out, improving the working environment.
03/ Long Service Life
Equipped with large-diameter circular chain, which enhances the overall structural strength of the scraper and extends the service period of the entire conveying components.
04/ Flexible Working Conditions
High crushing ratio and strong impact resistance. The product granularity and production capacity can be adjusted continuously, meeting various production needs.
05/ High Lump Coal Yield
Maximize the output rate of finished coal blocks from open-pit mines, thereby enhancing the economic benefits and value of the mining company.
06/ Easy To Assemble And Disassemble
No need to build a dedicated equipment foundation. The modular and split design makes transportation and disassembly quick and effortless.
Overall, the Feeder Breaker breaks away from the cumbersome layout of traditional separate crushing equipment. Relying on an integrated structure, it uses scraper chains for continuous transportation, synchronous pre-sieving, and the collaborative operation of toothed rollers for crushing. It completes the entire process of material transportation, screening, and crushing on the same horizontal plane. The equipment is adaptable to various complex working conditions such as high and low temperatures, freezing adhesion, and high bunker pressure. It has multiple advantages including low infrastructure investment, low noise, wear resistance, durability, convenient disassembly and transportation, and flexible adjustment of particle size and production capacity. The particle size and production capacity can be flexibly adjusted. It is an efficient and preferred equipment for the continuous processing of large blocks in industries such as mining, metallurgy, and construction materials.
