Apron Feeder
CSTMG apron feeder is a heavy-duty material handling machine designed for controlled feeding of bulk materials in mining, cement, and aggregate industries. Featuring overlapping metal pans driven by robust chains, it handles large, abrasive, or hot materials (up to 3000t/h capacity) without spillage. Its rugged construction withstands impact loads from crushers or hoppers, while variable speed drives enable precise feed rate adjustment. Ideal for uneven or oversized materials, apron feeders ensure continuous, reliable operation in harsh conditions with minimal maintenance.

CSTMG Apron Feeder Features
Heavy-Duty Constructionโ. Built with reinforced steel pans and forged chains to handle large, abrasive materials (up to 2000mm size) in mining and quarrying applications.
Material Versatilityโโโโ. Handles diverse materialsโlumps, powders, wet/sticky oresโwithout clogging or spillage, adapting to limestone, iron ore, or coal.
Precise Feed Controlโโ. Variable speed drives (mechanical or hydraulic) enable adjustable feed rates (ยฑ5% accuracy) for crushers or conveyors downstream.
Impact Resistance. Overlapping pans absorb shock loads from dump trucks or hoppers, protecting equipment from damage in harsh mining conditions.
โโHigh Capacityโโโ. Designed for throughputs up to 3000 t/h, ideal for bulk material handling in cement, coal, and mineral processing plants.

Apron Feeder Handling Materials
Metal Oresโ. Apron feeders excel in transporting metal ores such as iron ore (magnetite, hematite), copper ore (chalcopyrite, bornite), and gold ore (quartz veins, sulfide ores).
Non-Metallic Mineralsโ. For non-metallic minerals like limestone, dolomite, and marble/granite, apron feeders provide reliable material handling.
Coal & Carbon Materialsโโ. In coal and carbon material applications, apron feeders deliver run-of-mine coal (โค1500mm) to wash plants or crushers, handling high moisture content (โค15%) without slippage.
Aggregates & Quarry Stoneโ. Apron feeders are ideal for aggregate and quarry stone operations, feeding hard rock like basalt and granite (โค2000mm) to jaw or cone crushers.
CSTMG Apron Feeder Production Details
Pan & Chain Systemโ
- โโForged alloy steel pansโโ (16Mn or ZGMn13) with replaceable liners resist abrasion from iron ore, copper slag, and other harsh materials. Pan thickness ranges from 20-50mm based on application severity.
- โโSealed roller chainsโโ (ISO 1977 standard) with hardened pins and bushings provide 3-5x longer lifespan than conventional chains in high-wear environments. Self-lubricating designs are available for dusty conditions.
Drive & Transmissionโ
- โโDual-motor driveโโ with synchronized gear reducers delivers 15-500kW power, enabling capacities up to 7,000 t/h.
- โโFlexible speed controlโโ: Variable frequency drives (VFDs) allow feed rate adjustments from 0.01-0.3 m/s with ยฑ2% accuracy.
- โโDual transmission optionsโโ: Chain/sprocket system for heavy-impact applications (e.g., primary crushing); Gear-driven system for precise, low-maintenance operation (e.g., cement plants)
Tensioning & Protectionโ
- Hydraulic auto-tensioningโโ maintains optimal chain tension, preventing slippage and reducing power consumption by 10-15%.
- โโIntegrated safety featuresโโ: Overload torque limiters, emergency stop pull cords, dust-proof motor enclosures (IP65 rating)
CSTMG Apron Feeder Working Principle
The apron feeder operates through a robust mechanical system designed for controlled material transport in heavy-duty applications. At its core, the system utilizes โโmotor-driven chainsโโ and โโoverlapping steel pansโโ to create a continuous moving platform for bulk materials.
โโPower Transmissionโโ begins with an electric motor (typically 15-500kW) that delivers rotational energy to a gear reducer. This reducer converts high-speed, low-torque input into the โโlow-speed, high-torque outputโโ needed to drive massive loads. The torque is transferred via couplings to sprockets, which engage with heavy-duty roller chains.
โโMaterial Conveyanceโโ occurs as the chains pull interconnected pans forward in a linear path. Pans are engineered with โโoverlapping edgesโโ to prevent material leakage, while their deep profiles accommodate large lumps (up to 2,000mm). As pans move from the feed hopper to the discharge point, they carry materials like iron ore or coal at controlled speeds (0.01-0.3 m/s), adjustable via VFDs.
