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 Line can 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 line is under manufacturing. The current annual
capacity is 350,000 tons, and it will be nearly 500,000 tons after the second Upsetter line is finished.
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
Physical Defects: Without pinholes, micro-cracks, or fissures
We mainly produce:
1) Forged steel balls: Diameter from 15mm to 160mm;
2) Grinding rods: Diameter from 40 to 160mm*length;
3) High, middle and low chrome casting
balls: 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 metallographic 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.
