　 　Product Highlights
　　1. Integral casting of ultra-high manganese steel: Made from Mn18Cr2/Mn22Cr2 alloy, subjected to water‑quenching heat treatment, offering excellent impact resistance and wear resistance.
　　2. Reinforced Thickened Edge Design: The edges of the disc are thickened to effectively reduce erosion from sand and gravel, extending the replacement interval.
　　3. Uniform material distribution to reduce overall machine vibration: The equipment’s rotational centrifugal force evenly disperses the material throughout the crushing chamber, preventing uneven feeding and excessive wear.
　 　User Pain Points
　　The distribution plate is the core feeding component of a cone crusher, receiving ore discharged from the feed hopper. Under high‑drop impact, the fixing bolts are prone to shearing, causing the distribution plate to detach and leading to seizure of the mantle and bowl liner, or even motor damage. Conventional materials wear rapidly, requiring frequent replacement; uneven wear on the plate surface can also cause material segregation and uneven force distribution on the mantle, increasing downtime and maintenance costs.
　 　Solution
　　Our company’s ultra‑high‑manganese steel distribution tray undergoes water‑toughening treatment, resulting in rapid surface hardening under high impact while maintaining high core toughness to prevent fracture. The tray edges are thickened and reinforced to mitigate abrasive wear from sand and gravel. As it rotates with the main shaft, material is evenly distributed, preventing uneven loading and localized wear.
　　I. Product Description
　　The feed distribution plate (ore distribution plate) is mounted on the upper end of the cone crusher’s main shaft. It receives material discharged from the feed hopper and, using rotational centrifugal force, evenly distributes the rock into the crushing chamber, balancing the material bed and preventing uneven feeding and wear. The body is integrally cast from ultra-high manganese steel Mn18Cr2 or Mn22Cr2, followed by water‑toughening heat treatment for excellent toughness, impact resistance, and wear resistance. The edge of the plate is thickened to reduce wear from impact and brushing. It is compatible with various hydraulic cone crushers and is widely used in mining operations for crushing ores and producing sand and gravel aggregates.

　 　III. Product Features and Advantages
　　• Impact and wear resistance: Cast as a single piece from Mn18Cr2/Mn22Cr2 ultra-high manganese steel, the surface rapidly work-hardens under high impact loads while the core retains high ductility, preventing fracture upon impact.
　　• Edge Reinforcement for Erosion Resistance: The disc’s edge is thickened to provide extra wear allowance, effectively reducing abrasive wear caused by sand and gravel and extending the replacement interval.
　　• Uniform material distribution reduces vibration: As the main shaft rotates, centrifugal force evenly disperses the material around the crushing chamber, balancing the material bed to prevent uneven feeding and wear, thereby reducing overall machine vibration.
　　• Wide applicability: Compatible with various models of hydraulic cone crushers (standard, medium, and short-head types), widely used for crushing ores and aggregate in mining operations.
　 　IV. Why Choose Us
　　• Specializing in wear-resistant castings for harsh operating conditions: Rooted in China, we focus on the R&D and manufacturing of wear-resistant castings for demanding environments such as mining and power generation. Take the distribution plate as an example: specifically optimized to address the challenges of high‑drop impact and eccentric wear in cone crushers, it is integrally cast from Mn18Cr2 and Mn22Cr2 ultra‑high manganese steel. The surface undergoes impact hardening to HB400+, while the core retains high toughness. Combined with a thickened edge design, this effectively resists high‑drop ore impacts and erosion, extending service intervals and reducing downtime and maintenance costs at the source.
　　• We let the data speak, not empty talk of perfection: Casting processes are complex; we don’t promise “zero defects,” but we do promise “zero excuses.” Each batch of carrier trays undergoes a full inspection process—including precise measurement of tray dimensions, hardness testing, and magnetic particle inspection—to ensure accurate curvature and installation dimensions, as well as tight fit with the spindle. Complete test reports accompany each tray, demonstrating our accountability through data and action.
　　• Long-term partnerships—delivery is just the beginning: Our digital systems enable you to track production progress in real time; we respond immediately to quality concerns, with no delays; and each shipment comes with a comprehensive test report for your quality‑assurance records. We believe that a supplier’s approach to resolving issues is what truly defines its value.
　 　V. Production and Quality Assurance
　　• Premium Raw Materials: Carefully selected high-quality scrap steel and ultra-high manganese alloy additives, free of rust and oil, ensure the purity of the material used for the distribution plate at the source, laying the foundation for excellent resistance to fracture under high-impact operating conditions.
　　• Ultimate density: Ceramic sand combined with a large-diameter heating riser eliminates shrinkage porosity and cavities; the internal structure of the material distribution plate is dense, enabling it to withstand high‑drop ore impacts without cracking.
　　• Precision melting: Melted in a Fuji electric furnace from Japan, with real-time compositional verification via spectrometer to precisely control carbon and manganese levels, ensuring work-hardening capability and impact toughness.
　　• Flawless casting: 850°C ladle preheating combined with bottom pouring eliminates sand hole defects; the surface and thickened edges of the distributor plate are smooth and free of casting imperfections.
　　• Strengthened metallography: 30-second rapid quenching yields a uniform austenitic microstructure, achieving “hard outside, tough inside” for the material tray—surface hardness exceeds HB400 while the core retains high toughness, enabling it to withstand continuous impacts from ore without fracturing.
　　• Powerful shot blasting: cleans and hardens the surface, enhances the wear resistance of the material‑distribution plate, and extends the service life of the buffer brushes.
　　• Rigorous quality inspection: precise dimensional measurement and magnetic particle inspection ensure accurate disc curvature and mounting dimensions, achieving a perfect fit with the crusher’s main shaft.
　　• Transparent delivery: Scan a code to track progress in real time, with full visibility from material input to shipment.
　　 VI. Frequently Asked Questions (FAQ)
　　Q1: What is the delivery time?
　　Custom-made material distribution trays based on your drawings take 45–60 days. Expedited production can be arranged for urgent orders upon negotiation.
　　Q2: What is the minimum order quantity for the cone crusher distribution plate?
　　Minimum order quantity is one piece. Bulk purchases qualify for discounted pricing.
　　Q3: What packaging options are supported?
　　Fixed with steel brackets and protected by stretch film, or packaged in wooden crates, to meet the sea and land transportation requirements for vertical mill blades.
　　Q4: Can the customer’s logo be printed on the packaging?
　　Yes, but cast lettering is only supported on the non-working surface of the casting.
　　Q5: How often should the material distribution tray be replaced?
　　The specific service life depends on operating conditions such as ore hardness, feed particle size, and impact height, with significant variations among different mines. Employing highly wear‑resistant materials can effectively extend the equipment’s service life.
