The big variety of manufactured materials allows to satisfy all inquiries and needs. Grinding of different compounds (concrete, food, etc…), ball mill, tumble and vibro finishing, polishing, shot peening, filtering systems. They are often used as filler or cover elements in electrical, idraulic or thermal applications. 5x%C-0.70.
Read OnTheir function is to reduce by a grinding process the size of certain materials into a powdery form. The balls are described as Ni-Hard metal balls made of cast-iron, nickel, chromium, magnesium, silicon and carbon. The combination of these ingredients makes the resulting metal extremely hard and resistant to wear.
Read OnThe combination of Ni-hard rolls and high chrome table liners still holds a significant market share as the cheaper cast iron core is easier to machine. SBIPL manufactures the same through bi-metallic technology in the below trade.

Read OnBall chips from flaked, poor quality grinding balls result in shorter operational life of pumps, hydro-cyclones, and recirculating pipes. Grinding balls may be too light to have the sufficient kinetic energy to break rock. Mill flow rates are reduced. Inferior grinding balls cause peening when they are hammered against the discharge rate.
Read OnRepetitive drop tests were performed on Ni-hard and high chromium cast iron grinding balls with material toughnesses varied by heat treatment. Instrumented impact tests and bending fatigue tests were also performed on bar specimens with the same heat treatments, and correlations between drop strength and other strength characteristics were studied.

Read OnWoodcock (unpublished data) studied some aspects of this problem using Ni-hard balls and ceramic pebbles for comparison during grinding, and typical laboratory flotation procedures on 500 g ore charges. It was found that the amount of Ni-hard abraded from the balls was comparable with that obtained on similar ores to those used in the tests.
Read Onmaterial, so a designed #150-mm grinding ball must exhibit high hardenability. Nb is widely used in steels as a microalloying ele-ment for grain refinement.14–16 In this work, the proper-ties of Nb-free and Nb-containing grinding balls were investigated, and the feasibility of adding Nb to large-sized grinding balls to improve their ...
