I. Core Product Positioning
As a core component of heavy-duty material handling systems, the mine Plate feeder conveying plate /Feeding Plates/Chain Plates are specially designed for extreme operating conditions, making them ideal for harsh environments such as high-impact, wet and frozen, and large, abrasive ore handling. Duma Machinery offers a dual-product lineup of manganese-plate feeding plates and alloy-steel plate feeding plates, covering 90% of industrial application needs. Among these, the manganese-steel series of plate-type feeding chain plates are widely used in applications involving hard abrasives.
II. Comparison of Material Properties
Comparison dimension
Manganese plate feeder conveying plate
Alloy steel plate-type feeder conveyor plate
Surface hardness
Initial 400 BHN, reaching 550 HB after impact.
Stable 480–520 HB (high-temperature resistance)
Impact toughness
I ≥ 150 J (self-hardening increased by 30%)
I 80-100J (strong structural stability)
Applicable temperature
-30℃~400℃
-50℃~650℃ (special coating technology)
Typical lifespan
8,000–12,000 hours
10,000–15,000 hours
Economic efficiency
The comprehensive cost is as low as 0.12 yuan/ton-hour.
High upfront investment but 30% lower maintenance costs.
Technical Highlights:
● Shock-hardening black technology: The conveying plates of the manganese-plate feeder continuously self-harden during operation, with surface hardness increasing by 2-3% each week.
● Thermally stable architecture: The alloy steel plate-type feeder’s conveying plates undergo a gradient quenching process, maintaining a strength retention rate of over 92% even under high-temperature conditions of 600℃.
● Modular design: The chain plates of the plate feeder support quick disassembly and assembly, increasing replacement efficiency by 40% (using a snap-lock structure).
3. Innovative Production Process System
1. Vacuum Molding Casting Technology
● Using digital investment casting, we achieve dimensional accuracy of ±0.5 mm, reducing porosity defects by 80% compared to conventional processes.
2. Five-stage heat treatment process
● Gradient heating: Precise temperature control at 100℃/h to prevent cracking.
● Double solid solution treatment: Grain refinement achieved by heating at 1050℃ for 4 hours followed by 1100℃ for 2 hours.
● Rapid quenching: Instant phase-change strengthening achieved via a turbulent water curtain at 45℃
3. Intelligent Detection System
● Online spectral analysis: Real-time monitoring of the content of elements such as C and Mn.
● 3D laser scanning: 100% full-size tolerance inspection
● Digital validation: Predict the stress distribution after 200,000 impacts through simulation.
IV. Strict Quality Control Standards
1. Materials Traceability System
● Feeder plate material for the manganese plate feeder: Complies with GB/T 5680-2010 Manganese Steel Standard (Mn13Cr2).
● Alloy steel Plate feeder conveying plate Material: Certified to ASTM A128 Grade D

V. Typical Application Scenarios
Scene 1: Iron Ore Crushing Line
● Pain point: The iron ore abrasion index AIV exceeds 16, causing traditional chain plates to fail within just 3 months.
● Solution: Configure a manganese-plate feeder with conveying plates and a skirt-type leak-proof design.
● Results: Lifespan extended to 9 months, and power consumption per ton of treated waste reduced by 0.8 kWh.
Scene 2: Metallurgical High-Temperature Slag Treatment
● Pain point: 650℃ slag causes thermal deformation of ordinary steel plates.
● Solution: Alloy steel plate-type feeder conveyor plate + ceramic composite coating
● Results: The continuous operating temperature tolerance has been increased to 700℃, and the maintenance cycle has been extended by a factor of three.
