How to Choose Qualified Wear-Resistant Ceramic Liners from Their Appearance?
Wear-resistant ceramic liners are widely used as wear-resistant linings for ball mills, pipelines and other equipment. The specific identification methods are as follows:
Spots and impurities: For spots or impurities with a maximum size ≤2mm, each tile is not allowed to have more than 4 pieces; for those with a maximum size>2mm, they are not allowed on the front, and no more than 4 pieces are allowed on the back and side where 2mm
Corner defects: For corner defects with a depth ranging from 4mm to 6mm, each tile is not allowed to have more than 2 pieces, and those with a depth greater than 6mm are not allowed.
Edge defects: For edge defects with a depth ranging from 4mm to 6mm or a length ranging from 8mm to 15mm, each tile is not allowed to have more than 2 pieces, and those with a depth greater than 6mm or a length greater than 15mm are not allowed.
Cracks: Cracks are not allowed on the front surface. For cracks on the front surface and side surfaces, or between side surfaces, with a width ≤0.2mm and a length ranging from 5mm to 15mm, each tile is allowed to have up to 3 pieces. However, if the width is >0.3mm or the length is >15mm, they are not allowed.
