Applications
Cement mills - 2nd compartment Raw mills - 2nd compartment or classifying part DIN drilled mill shells (250x314mm) Mill diameter : 3.0m to 4.8m
Future developments : Mill diameter > 4.8m Non DIN drilled mill shells
250
314
-
Traditional classifying liners
Users feedback as per prior study
Thick plates (up to 50kg) difficult to handle hazardous to handle loss of grinding volume
Loss of classifying efficiency with wear non-reversible
-
Different plates to protect shell to classify media
Light plates (25kg max) for easy handling & assembly for safety
Constant classifying efficiency all through lifecycle
-
Working principle : media classification by spiral effect
LAB PICTURE
NUMBER AND POSITION OF SPIRAL & DEFLECTORS ARE DETERMINED BY PROCESS STUDY
OF MILL CHARACTERISTICS & OPERATING PARAMETERS AND COMPARED WITH LABORATORY AND INDUSTRIAL ON SITES TESTS

1 BASE PLATE & 1 SUPPORT PLATE WHATEVER THE DIRECTION OF ROTATION (clockwise or counterclockwise)
3 BASE PLATES & 3 SUPPORT PLATES COVER ALL MILL DIAMETER RANGE (3->3.7m / 3.8->4.7m / ->4.8m)
