Description

 一、 Product Profile

 The semi - autogenous grinding machine, also known as the SAG mill, is a high - efficiency crushing and grinding machine with a large diameter and a short length. With the development of mining equipment in the world, semi - autogenous grinding machines are widely used in metal mines such as gold mines, copper mines and iron mines. At present, the diameter of the world's largest semi - autogenous grinding machine has exceeded 13 meters. The domestic mill manufacturer with CITIC Heavy Industry as the leader has also successfully manufactured and operated several large semi - autogenous grinding machines (SAG mills) with a diameter of more than ten meters. Such a mill has a particularly high quality requirement for the steel ball. Because the steel ball has a large impact radius in the mill, the impact resistance of the steel ball is particularly high, especially not broken. Casting grinding balls are limited by the current world casting level limit, and can basically not meet the semi - autogenous grinding machine with a diameter of more than 5. 5m. At present, the large - diameter forged steel ball is the preferred impact ball for the semi - autogenous grinding machine SAG grinding machine. Its high impact value, unbroken, and rounded quality make it occupy the entire semi - autogenous mill steel ball world.

Note

Support OEM or customize special ingredient steel balls according to customer requirements. The hardness of small straight D steel ball is higher than that of large diameter steel ball. If the hardness range is required, it can be adjusted by heat treatment process.
