Detailed
What is High Chrome Cast Grinding Balls
Cast Grinding Balls are spherical grinding media produced by melting metal alloys (like iron/chromium), pouring molten metal into molds, and heat-treating for hardness.
High chrome cast grinding balls offer a practical balance of performance and cost for moderate grinding conditions.
Core Features
1.Process: Manufactured by casting process (molten metal poured into molds)
2.Chromium Hardness: Made of high-chromium alloys (Cr content ≥13% for premium wear resistance).
3.Low cost: Cost-effective grinding media for bulk material crushing.
High Chrome Cast Grinding Balls
Size: High chrome casting grinding balls are available in Φ15-Φ130mm diameter sizes.
Weight: Cast high chrome balls are available in weights from 13g to 3314g.

Application
1）Mining and Mineral Processing
Cast high chrome grinding media has been designed to effectively liberate a wide variety of minerals such as gold, silver, lead, zinc, copper, iron during the comminution process.
2）Cement Bulding Materials
Cast high chrome grinding media offers optimal performance for the dry grinding of limestone and cement in all types of ball milling common to the cement industry. The product is typically tempered for dry cement applications.
Finish milling – Product can be designed to effectively grind clinker in dual or mono chamber cement mills. Optimised ball charges can ensure proper grinding efficiency to fully utilise the mill power to produce the required Blaine.
Raw milling – Cast high chrome grinding media offer a longer lasting ball for dry or wet raw milling of the kiln feed material.
Coal milling – Corrosive grinding conditions in milling of fuel materials for the kiln can be better handled by our more durable cast high chrome grinding media.
3) Power plant:
Pulverizing coal into fine powder for boiler combustion in power plants.

FAQ
What are the key advantages of cast grinding balls over forged balls?
Lower cost (30%-50% cheaper), superior wear resistance with high-chromium content (HRC 58-65), ideal for continuous grinding in medium-impact conditions.
What certifications are required for exporting cast grinding balls?
Mandatory documents include ISO 9001, wear test reports (ISO 3290-1), and material composition analysis. Some countries require CE or SGS certification.
How do you ensure grinding balls arrive intact during bulk export shipping?
We use ton bags( liner inside) with reinforced impact frames inside containers. Ocean shipments include breakage insurance, guaranteeing ≤1% breakage rate.
