Rubber lining for grate ball mills : Product description
Complete set of rubber lining is used in the grate ball mills at the grinding stage I (ball diameter of 100 - 120mm) and includes head lining, discharge end lining (grate, elevator, central armature), shell lining, door and door area plates, and set of fixture elements. Rubber lifter bars include directly vulcanized steel armature.
Shell and end lifter bars are fastened with М36, М42 bolts.
The lining includes rubber plate and combined rubber-metal lifter bar consisting of wear-resistant rubber directly vulcanized onto manganese steel armature.
Metal component of lifter bar absorbs impact loads and provides the secure fastening of lining.
The rubber component of lifter bar protects lifter bar against the abrasion and tightly presses the rubber plate thus preventing washout. Lifter bars are fastened with М36, М42 bolts.
The used rubber grate offers following advantages:
- significantly lower wear rate of rubber grate as compared with steel grate;
- higher process efficiency by the finished product grade yield than that with the use of steel grates;
- grate self-cleaning capability;
- rubber grate service life is 1.5 - 2 times as that of steel grate.
The rubber elevator used for ground product discharge from the mill offers following advantages:
- simple design;
- low weight allowing substantial reduction in labor input at assembly and disassembly;
- tight contact prevents slurry leakage through lining and bolt holes;
- rubber elevator service life is 2 times as that of steel elevator.
