ADVANTAGES OF ALUMINA LING BRICK

1)High density and small thickness can increase the loading volume and promote the production capacity. 2)

Low wear loss and long service life (it is 3-5 times compared with nature stone liner and 2-3times compared

with rubber liner), which can reduce the installation times. 3) Main material is alumina which has no pollution

to the grinding object.

 INSTALLATION

1) Before installing, the ball mill inside surface should be clean; if the iron surface is worn seriously, it should

be repaired by welding. 2) Usually use 425# white cement and few 107# glue as adhesive and the gap should

be within 2mm .3) The installation order: A. 2 end walls should be installed first with

straight brick and semi-straight brick. B. After finishing the installation of 2 end

walls, the cylinder wall should be installed with straight brick and trapezoidal brick

so that the brick bottom can cling to the inside surface of cylinder wall tightly, using

semi-straight brick and semi-trapezoidal brick accordingly. If the last row can not be

installed by straight or trapezoidal brick, then it is filled by flake brick and sealed with white cement. 4) When

all the installation is completed, clean the surface, dry for 2 days, filled with full water for 3 days, finally, take all

the water out and dry for more than 7 days
