Grinding Steel Ball

1. Product Introduction

Forged Grinding Steel Balls Diameter:20-150mm Hardness: HRC55-65Steel Materials: middle carbon alloy steel, its purpose is to reduce its fragility to assure its good toughness and impact in the SAG mill.Application: Widely used in SAG Mill and Ball mills for gold mines, and copper mineral processing plants.

Processing: The production process is using upset forging and rotary forging. The balls undergo the heat treatment of one quench and twice temper. As a result, the grinding balls have a better inner structure and density to improve the grinding efficiency and reduce the grinding balls' consumption.

New Technology: Our newly invented Intelligent Upsetter produce 40 pieces per minute for diameter 100mm balls (250 tons per day) and 240 pieces for 60-80mm balls, which is the third only sets in the world and the first set in Asia, and the second Upsetter nder manufacturing. The current annual capacity is 350,000 tons, and it will be nearly 500,000 tons after the second Upsetter inished.

Essential Characteristics:

 High Hardness at the Surface and slowly decreasing at the core

 Good Wear Resistance

 Able to withstand mechanical stress

 No Breakage

 Even Wearing

sical Defects: Without pinholes, micro-cracks, or fissures

Â

 We mainly produce:

 1) Forged steel balls: Diameter from 15mm to 160mm;

2)Â Grinding rods:Â Diameter from 40 to 160mm*length;

3)Â High, middle and low chrome casting balls:Â Diameter from 17mm to 150mm.

 We have a technical team with over 20 years of experience, a professional quality control team with over 20 years of experience, and a skilled worker team with practice experience. The raw materials, chemical components, hardness distribution, impact toughness, drop test, and metallograc structure are all controlled by the complete set of advanced equipment. Our company has full ability to provide you with high-quality products, reasonable price, timely delivery, and satisfactory service.
