The Coal Mine Feeder is the connection between the mining system and the material handling system, which can efficiently process a wide range of materials, thus maximizing the operational efficiency of the company.
How Coal Mine Feeder Work?
Coal Mine Feeder consists of chain conveyor and crushing unit, which realizes the combination of feeding and crushing functions.
Conveyor Parts
The materials are directly unloaded into the hopper by dump trucks, or unloaded into the hopper by bulldozers or loaders, and then When the drive device of feeder starts to run, the drive sprocket drives the chain to move horizontally in the conveying box and drags the material forward at the same time.
Crushing Unit
When the chain and the material through the rotary teeth roller in the crushing box, because the large material cannot pass through the specific space between the teeth roller and the base plate, the large material will be knocked, squeezed and stretched by rotating toothed rollers until broken into small materials which are allowed to pass through.
In general ,the Coal Mine Feeder can crushes the large materials(800mm-1500mm) into medium sizes(200mm-500mm).
Coal Mine Feeder Unique Advantages
Compared with other brands of Coal Mine Feeder s, our Coal Mine Feeder s have the function of pre-screening and optional crushing form.
01/Pre-Screening
Dynamic And Static Pre-Screening
Pre-screening consists of two methods: dynamic pre-screening and static pre-screening, which are configured according to different working conditions.
Benefits
The material receiving section adopts static screening method, the static screening grate is fixed on the conveyor box by the rail, which is suitable for the screening of large particle materials.
The non-material receiving section adopts dynamic screening method. Integrate a specially designed sinusoidal disturbance screen on the conveyor box, which is suitable for screening small particles and sticky materials. The non-receiving section adopts sinusoidal disturbance screening method to prevent any material from getting stuck.
The material is pre-screened and then crushed, which can avoid excessive crushing and reduce the production of powder, maximize the yield of mineral blocks, and improve the economic benefits and value of end users.
02/Crushing Unit
Teeth Roller Crusher
Powerful function Crushing Roll(picks) with picks and a pick pattern designed for chain conveyors to crush material to the desired output size. Since the material is broken, not squashed, the lumps are consistent, producing less waste material and maximizing product value.
Benefits
The crushing teeth are made of special formula materials after precision casting and heat treatment, with high strength, wear resistance and impact resistance.
The crushing teeth adopt high frequency heating assembly, the structure is firm, reliable and durable.
Unique and novel tooth design structure, deep spiral distribution, strong biting capacity, high production efficiency.
The Hammer crusher is connected to the motor by the triangular belt. The height of the Hammer crusher can be quickly adjusted by means of a hydraulic device to adjust the discharge size of the crushed material in order to meet the needs of different customers.
Benefits
The modular design of the tooth head is fixed to the crushing hammer by high-strength bolts, enable the targeted and efficient replacement of individual tooth head.
The crushing method using a breaker hammer has a significant effect on the presence of ultra-large pieces of materials in open-pit mines.
Hammer crusher is a new type of crusher developed for large particle size materials, with wear-resistant, large processing capacity, long service life and so on.

Crusher Parts
Teeth Roller (Picks)
The crushing teeth are made of special formula materials after precision casting and heat treatment, with high strength, wear resistance and impact resistance.
The crushing teeth adopt special installation technology and design structure: adopt high frequency heating assembly, the structure is firm, reliable and durable. Unique and novel tooth design structure, deep spiral distribution, strong biting capacity, high production efficiency.
Hammer Crusher (Picks)
The hammer crushing tooth head are fixed by the way of movable teeth head, which is easy to replace and reduce loss. The crushing method using a breaker hammer has a significant effect on the presence of ultra-large pieces of materials in open-pit mines.
Conveyor Parts
Drive Device
Our drive system utilizes an AC variable frequency drive system that integrates software with electronic and mechanical systems to provide precise conveyor speed control and overload protection.
Chain & Scraper
The hauling chain adopts a high strength mining circular chain connected by connecting rings, with a long service life and easy change. The conveyor scraper is made of alloy steel, which has the advantages of high strength, high tensile strength, compact structure, withstands strong impact, installs easily and others.
Sprocket & Shafts Assembly
The Head/Tail Shafts are designed for disassembling maintenance as a whole unit. Shafts designed with alloy hardened, tempered and stress relieved steel. Sprockets are designed with either sheet flame hardened steel or split steel to provide additional maintenance options.
Tension Device
There is a hydraulic adjustment device at the tail of conveyor body, and the manual hydraulic pump adjustment device can realize that even if the feeding end of the machine is buried in the "material", it can also quickly adjust the chain tightness to ensure the equipment stable operation.
Conveyor Box
The Conveyor box consists of a number of small Conveyor boxes connected by high-strength bolts in a row, the main function is to connect the head and tail and carry the conveyor chain sliding in it to transport materials. The Conveyor box is welded by high strength wear-resistant steel plate, strong structure and beautiful appearance. The inner liner plate is made of wear-resistant plate and connected by bolts, making it easy to replace.
Coal Mine Feeder Features
01/ Pre-sieving Function
The equipment can be optionally equipped with a grate or roller design. Before the material enters the crushing stage, it can pre-sieve out the qualified particle sizes of powder and small pieces. This not only significantly reduces the phenomenon of over-crushing, improves the particle size ratio of the final product, but also directly enhances the market value of the material, bringing you a better return on investment.
02/ Sturdy Frame Structure
The main frame is made of high-strength prefabricated steel with anti-fatigue design, featuring excellent structural integrity and anti-deformation capabilities. Its modular design not only enables rapid on-site assembly but also can handle extreme mining environments such as long-term corrosion and high vibration with ease, ensuring the lasting stability of the equipment foundation.
03/ Advanced Drive System
This system eliminates the traditional chain drive and safety pins, and adopts torque control coupling and direct hydraulic drive. This design not only reduces operating noise at its root, but also improves energy utilization efficiency, and at the same time reduces maintenance troubles caused by frequent replacement of cutting elements.
04/ Hydraulic Dual-power Drive
The innovative dual-pump merging technology enables smooth and soft startup of the equipment as well as stepless speed regulation. It can effectively alleviate the overload impact of the crusher when encountering large pieces of material, protect the core components, and successfully reduce energy consumption by more than 15%.
05/ INtegrated Planetary Gear Reducer
The core transmission adopts a heavy-duty planetary gear box, with a transmission efficiency of up to 96%. Its outstanding design and manufacturing process ensure a maintenance-free operation life of up to 20,000 hours, significantly reducing the maintenance costs and downtime risks for users.
06/ Intelligent Operation And Maintenance System
The equipment integrates two intelligent systems:
Predictive Maintenance System: Based on big data analysis, it can predict the remaining lifespan of key components in advance, issue early warnings, and effectively prevent unexpected downtime. Centralized automatic lubrication system: It can precisely control the lubrication intervals and injection volumes based on operating time and load conditions. It is remotely programmable and can completely eliminate the risks caused by insufficient or excessive lubrication.
