IGH-DENSITY ALUMINA
LININGS. XIETA®–92

High-density alumina linings are used to avoid contamination from oxide in the material being ground, across all types of mills. These linings adhere to the metallic interior of ball mills, preventing contact between the grinding media and the raw material with the metal casing.
Xieta International, S.L. manufactures high-density alumina parts suitable for lining mills of various diameters, from as small as 600 mm to as large as 3,800 mm. For all mills, we offer tiles in thicknesses of 40, 60, 70, and 100 mm, depending on the diameter of the mill and the specific needs of each application.
Proper maintenance and mill operating conditions (rotation speed, ball load, etc.) are essential for ensuring the durability and performance of the lining.
Xieta International, S.L. has a team of highly qualified technicians available to provide personalized support to all our clients.
