Abstract

The invention discloses a ball-milling tank capable of bearing high pressure and resisting abrasion, and a manufacturing method thereof. The ball-milling tank comprises an outer sleeve, an inner lining, a valve, a seal ring and a grinding ball arranged in a ball tank, wherein the outer sleeve is made of a metal material with high yield strength, the inner lining is made of a metal material with good wear-resisting performance, and the outer sleeve is combined with the inner lining tightly; and the seal ring is arranged in a groove on the surface of the outer sleeve. The ball-milling tank is characterized in that the outer sleeve is made of the metal material with the high yield strength and can bear high-pressure air, and the inner lining is made of the metal material with the good wear-resisting performance to improve the wear-resisting performance and contact fatigue performance of the ball-milling tank. In the ball-milling tank, the outer sleeve is combined with the inner lining, so that toughness and hardness are complementary mutually, the impact resistance of the ball-milling tank is improved, the service life of the ball-milling tank is prolonged, and the ball-milling tank is safer and more reliable.
