Threepiece "compressiontype" liner bolt sealer is designed to prevent leakage of slurry. or dust from mill liner bolt holes. Used in conjunction with Grade 5 (highstrength) bolts, this assembly is generally applied to rod mills over ′ in diameter and ball and. autogenous mills greater than ″ in diameter.
SAG Mill Liner. Short Description: SAG Mill Liner from HG use CrMo materials (AS2074 Standard), SAG Mill Liner provides superior impact and wear resistance in all semiautogenous milling applications. To choose the right material for the right application is our mission, we are always working together with our customer to achieve this.
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

the influence of these factors on speed, lining board, fill level ratio, and steel ball diameter of a SAG mill. Li [7] controlled the cone crusher's eccentric speed and closed side setting (CSS) parameters in the semiautogenous grinding process by dynamically modeling the SAG millpebble crusher loop to improve the SAG mill throughput.
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
Semiautogenous mills or SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages. Lower lifetime cost
Generally speaking, and depending on current ore prices, the loss of production from a large SAG mill being down for maintenance or repairs can cost a mining operation between US30,000 and US250,000 per hour. The highwear liner components of a large SAG mill can take anywhere from 40 to more than 120 hours to replace, depending on worn liner ...

My first guess is that the new liner has a face angle that is tossing the balls against the far wall of the SAG mill causing them to break on impact with the liner. In the sort term you can drive up the load in the mill so that the balls are impacting the rock charge instead of the opposite liner, or slow the mill down if you have a variable ...
When SAG mill liner bolts loosen, break or stretch beyond limits, liner impairment and degraded performance are generally next on the agenda, followed by mill stoppage for repair or replacement. ... most sites carry out a retorque 24 to 48 hours after a reline shutdown has ended. This costs 8 to 12 hours of lost production, but is standard ...
SAG mill operation is more dynamic, and typically requires a higher degree of process control sophistication. Though more complex in AG/ SAG circuits relative to the crushing plants they have largely replaced, these issues are well understood in contemporary applications.
