Why Is Our Apron Feeder Suitable For A Variety Of Complex Operating Environments

As a feeding equipment, apron feeder must have strong impact resistance, high wear resistance, large processing capacity, long service time, maintenance period and other advantages. In order to meet a variety of complex working conditions, our company has made great efforts in the design and production of apron feeder.
We produce heavy apron feeder for weijimao open-pit mine in inner mongolia with large temperature difference between day and night, large annual temperature difference, thick frozen soil layer, large wind and sand, perennial wind speed: 16m/s~20m/s, maximum annual wind speed 40m/s and other very short and bad weather.
Our company fully considered the characteristics of the cold winter of the open-pit mine in inner mongolia, apron feeder supporting equipment have good low-temperature resistance, can meet the requirements of long-term continuous production operation, start-up, operation and shutdown stable, safe and reliable. Meet the requirements of full load starting and braking, all equipment can ensure more correct design and manufacturing, safe and continuous operation, without excessive stress concentration vibration, temperature rise, wear, corrosion and aging and other problems. The noise and vibration of equipment operation meet the requirements of relevant national standards.

The groove plates fixed on the chain are welded structural steel with special section design. The groove plates and groove plates are bonded to avoid material leakage between the brackets. The groove plates are fixed with anti-wear countersunk bolts and the chain. It is particularly important to eliminate the impact load energy. The impact load is first absorbed by the support plate and causes the elastic deformation of the slot plate. Then the impact load is transferred to the main frame structure through the slot plate and absorbed by the main frame structure.
The groove plate structure is designed as a single arc overlapping, which is tight and has good leak-proof performance. The groove plate material is not less than 40m2, the thickness is not less than 25m, the whole processing process adopts fixed mold docking, welding, heat treatment, machining and other pipelin-type seamless production line, with high processing accuracy, long service life, simple installation, easy to replace and so on. The conveyor plate is made of low-alloy low-temperature rolled steel or welded wear-resistant plate, which can withstand multiple shocks without deformation, and easy to replace wearing parts. The pallet consists of a linked transport pallet and a non-lubricated tow chain with a sealed lip and the lower part of the pallet is reinforced. In order to ensure high transport capacity, every three trays are fitted with additional square steel. The trays are designed to be stacked on top of each other to ensure a minimum gap between the connected trays to avoid material spills.

Cylinder-bevel gear planetary reducer, reliable performance, precise transmission; no recoil, with sufficient strength; the output torque-speed characteristic curve is hard. High efficiency, efficiency of more than 90%; because all transmission parts are strictly treated, finished and ground; good contact and lubrication; smooth operation, low noise; the output shaft and input shaft have no additional axial force, and the main parts are made of bearing steel. Compact structure and small volume; durability long life.
Apron feeder’s traction chain is a self-lubricating and sealing device with a hardened steel shaft. After hardening, the toughness and impact resistance of the traction chain are improved, with good wear resistance and long service life. For this project, a set of hydraulic disconnecting chain device is specially equipped for the mine to repair and replace part of the chain after 5-8 years. The removal tool comprises a hydraulic system and a mechanical thimble function of the release device. Easy to use, easy to operate. The sealing device prevents abrasive substances from entering the internal parts of the chain, avoiding premature wear and prolonging the service life of the traction chain 20 30%. Traction chains with sealing and self-lubricating devices reduce friction, reduce maintenance costs and increase service life. The traction chain is easy to disassemble and replace during replacement.
The main frame adopts sufficient strength and stiffness, and the weld is solid and beautiful and uniform; the profiles and plates used in manufacturing are made of high-quality steel, and the material surface is pre-treated with grinding, shot peening or pickling, etc. The whole processing process adopts a fixed mold butt, welding, heat treatment, machining and other pipelined seamless production lines, with high processing accuracy, long service life, simple installation and so on. After the production is completed, the stress is removed to ensure that the appearance is not damaged or deformed.
The apron feeder we produced for inner mongolia officially adopts the above technology and processing technology to ensure that our apron feeder has no quality problems since installation and production, stable and safe operation, and won high praise from customers. In the future, we will continue to increase research and development efforts and improve better service to provide you with better quality products and services.
