Brand: SHINING

Type: WBZ1524×5615mm Heavy-duty Apron Feeder

Application: Mining, cement, metallurgy, coal, chemical, ports, and other heavy industries

Core Function: Continuous, uniform feeding of bulk heavy and abrasive materials from storage bins or transfer hoppers to crushers, batching equipment, or conveyors.

Overview

The SHINING WBZ1524×5615mm Heavy-duty Apron Feeder is a robust feeding solution designed for the most demanding material handling environments. Built with ultra-wear-resistant Mn13Cr cast slats, T171 tank track chain, and a 30 kW variable frequency drive system, this feeder delivers exceptional impact resistance, long service life, and stable operation under extreme conditions. It is widely used for primary crusher feeding and intermediate bin discharge in cement plants, mines, and other heavy industrial facilities worldwide.

Key Technical Advantages

1. Ultra-Wear-Resistant Mn13Cr Cast Slats

The feeder slat is precision-cast from high-manganese wear-resistant steel (Mn13Cr) with a base thickness of 20 mm and reinforced ribs. Compared to welded Q235 or ordinary steel slats, Mn13Cr offers significantly higher hardness, better toughness, and outstanding impact resistance. This reduces wear and deformation, extending service life by 3 to 5 times while lowering maintenance costs.

2. T171 Tank Track Chain for Extreme Loads

The feeder uses T171 tank track chain as its traction component. Chain plates are made of 35MnB steel with quenching and tempering, while pins and bushings are 40Cr steel with high-frequency quenching to HRC 52-56. With an ultimate tensile strength of 855 kN, this chain is designed for extreme abrasion and heavy loads. Advanced sealing retains lubrication and minimizes maintenance, outperforming standard engineering chains in harsh environments.

3. High-Power Variable Frequency Drive System

The drive system pairs a YVF200-4 variable frequency motor (30 kW, 1450 r/min, 380V/50Hz) with a P2KA14 planetary gear reducer (total ratio 280). The reducer features torque arm mounting and a locking disc for direct shaft connection. This setup delivers strong output torque and traction, ensuring stable feeding under heavy load and eliminating skidding, jamming, or power insufficiency common in low-power feeders.

4. Premium Molybdenum Disulfide Grease Lubrication

All transmission components—drive sprockets, driven sprockets, carrier rollers, and bearings—are lubricated with high-performance molybdenum disulfide grease. This grease forms a stable lubricating film under heavy load, high temperature, and harsh conditions, offering excellent extreme-pressure resistance, wear resistance, and adhesion. It reduces friction and noise, prevents seizing, and extends the life of bearings and transmission parts.

Technical Specifications

Custom designs with different widths, center distances, speeds, and capacities are available upon request.

Core Component Materials

The feeder is built with premium materials to ensure long-term durability. Below are the main components and their specifications:

Structural Features

The frame is a welded steel structure with bolted joints for easy transport and assembly, featuring reinforced sections for high rigidity under impact loads. The drive train follows the sequence: motor, elastic pin coupling, planetary reducer, locking disc, and drive shaft, with variable frequency control enabling automatic coordination with downstream crusher load. The tensioning device is screw-type with tapered coil springs, compensating for chain stretch and absorbing shock. Support and return rollers use double-row self-lubricating rolling bearing assemblies with dense spacing for heavy impact zones. The machine cover integrates guide plates, support columns, and tail baffles to contain material and minimize spillage.

Operating Conditions

The feeder operates at inclinations from 0° horizontal up to 25°, depending on material characteristics. Ambient temperature range is -20°C to +50°C, with special versions available for extreme climates. Typical materials include limestone, clay, shale, iron ore, copper ore, coal, and slag, with maximum particle size up to 1800 mm. Control is via AC variable frequency drive with remote and local options.
