Introduction:

The K-Type reciprocating feeder is one of the primary equipment in coal production sysytems. Its main function is to uniformity load materials from coal bunkers or unloading pits onto conveyors or other screening and dtorage devices.

This feeder utilizes a crank-linkage mechanism to drive a 5° downward-inclined base plate to platform linear reciprocating motion on rollers. When the motor starts, it drives the inclined base plate through an elastic couping, reducer and crank-linkage mechanism, uniformly dischargeing coal onto transportation machinery or other screening equipment. It is duitable for transferring low-abrasive, low-sticky loose granular and powdery materials from feeding equipment to receiving devices.

The K-Type reciprocating feeder is specifically designed for feeding coal and other low-abrasive, low-sticky loose granular materials, continuously and uniformly discharging materials from storage bins or pits onto transportation equipment or other screening devices.

Working Principle:

The K-Type feeder consists of a frame, base plate (feeding trough), transimission platform, hopper, gate and idler roller. When the motor starts, it drives the 5° inclined base plate to perform linear reciprocating motion on the rollers through the elastic coupling, reducer and crank-linkage mechanism, uniformly discharging materials onto other equipment. This machine is available in two configurations: with hopper and without hopper.

The coal feeder comes in two structural forms: 1. With regulating gate  2. Without regulating gate. The feeding capacity is controlled by adjusting the regulating gate.

Key Features

1. Simple structure, reliable operation and easy adjustment and installation.

2. Equipped with torque-limiting hydraulic coupings for full-load starting and reliable overload protection.

3. Light weight, compact size, reliable operation, long service life and easy maintenance.

4. Feeding capacity up to 1200 tons per hour (for coal), making it one of the largest reciprocating feeders available.

5. Adopts planar double-enveloping worm gear reducer design, providing high load capacity and high transmission efficiency.

6. Adjustable gaps between side linears, inclined liners and base plate allow precise gap control, significantly reducing material leakage.

7. Symmetrically arranged driving device with double push roads ensures balanced force distribution and smooth transmission, eliminating twisting and swinging of the base plate during reciprocating motion.

8. The base plate is reinforced with vertical rib plates and supported by three fully-length idler rollers, ensuring sufficient rigidity and eliminating the deformation problem common in traditional reciprocating feeders.

9. Wear liners are composed of small wear-resistant steel plates, making replacement lightweight and easy. Only worn liner sections need to be replaced, optimizing material utilization and reducing maintenance costs.

Applications

1. Mining  and Coal Preparation Industry

Used for bulk material transfer in mines, shafts and coal preparation plants, continously and uniformly transferring coal, ores and other materials onto belt conveyors or screening equipment. Suitable for both open-pit and underground operations, handling large ore blocks, coal and other low-adrasine loose materials.

2. Port and Logistics Industry

Applied in bulk cargo terminals for efficient loading and unloading of coal, grains and other bulk materials. Works in conjunction with belt coneryors or storage devices to ensure continuous supply of large quantities of bulk materials.

3. Metallurgy and Chemical Industry

In metallurgy, used for material supply in continuous casting processes, such as quantitative feeding of coke and metal powders. In chemical industry, transports powdery or granular raw materials like fertilizers and plastic pellets, meeting the requirements of mixing processes.

4. Energy and Power Industry

Used in thermal power plants for processing and conveying fuel such as coal powder, ensuring stable combustion in boilers. Inbiomass energy plants, handles loose fuels like straw and wood chips.

5. Construction and Building Materials Industry

Used on construction sites for uniform conveying of sand, cement and other building materials, supporting continuous production of concete mixing plants. In building material factories, works with crushers or screening equipment to improve aggregate processing efficiency.

6. Grain and Food Processing Industry 

Enables precise feeding of grains and feeds in grain processing plants, avoiding material accumulation or waste. In food industry, used for hygienic closed conveying of granular raw materials such as sugar and salt.
