High Hardness Grinding Ball, Forged Steel Foundry Tungsten Carbide Ball Grinding Diameter: 100mm-150mm Hardness: HRC55-65(Surface and Volumetric) Characteristics: High hardness, good wear resistance, no breakage. We use the special steel materials to produce the SAG balls to ensure the good performance of high hardness, high impact and wear resistance applicable in SAG mills.
Grinding steel rods: Diameter: 50-120MM Length: tailored. Hardness: HRC45-55 Application: Various rod mills for metalic mines,phosphate mines,silca sand makings. Charateristics: high hardness,no bending in the application,good wear resistance with long life. The grinding rods are produced by alloy steel materials, which have got the national patent. The grinding rods with heat treatment can improve the production and decreased the consumption up to 30% than the round steel bars used in the international market. We have one complete strict quality control systems from the materials, production process and finished products to ensure the steady quality of the grinding rods.Each piece of grinding rods has to be inspected qualified before delivery.
U shaped steel: U shaped steel is a kind of steel that the cross section is like the English letter U. Basic information Chinese name: U-steel support Application: Used in mine tunnel Characteristic: Bear big pressure Steel type: The type of the sixties Usually type:25U, 29U, 36U

Withstand high pressure, support long time, easy to install and easy to deformation. Arch steel support lift straight wall semi-arched shed in the Ready Roadway Intersection of applications, and achieved remarkable results. Optional retractable U-shaped steel bracket, solves the problem of tunneling support. U-shaped steel bracket than other rigid support with a scalable and reliable carrying capacity to adapt to the load and deformation of soft rock, cross utilization is high, easy to stand back support small work of maintenance, support recovery reuse rate, reducing the pit wood used, environmental benefits are clear.
