CAPACITY
FEED SIZE
The Rod Mill for Sand Making is a cylindrical grinding machine that uses long steel rods as grinding media. It is designed to process pre-crushed feed up to 30 mm and produce a controlled product below 5 mm for manufactured sand and coarse-grinding applications.
Unlike a ball mill, the grinding rods contact the material along a line rather than at individual points. This selective grinding action helps reduce overgrinding and excessive fines while producing a more controlled particle-size distribution.
XINGAONAI BMJ rod mills are available in capacities from 80 to 500 tph. The final capacity and product gradation depend on the material hardness, abrasiveness, moisture, feed distribution, discharge configuration and operating conditions. Wet or dry grinding and the appropriate discharge arrangement should be confirmed according to the specific project.
Controlled Product Gradation
Line-contact grinding between the steel rods and material reduces excessive pulverization and helps produce a more controlled particle-size distribution with fewer unwanted fines.
Reduced Overgrinding
Compared with ball grinding, the selective action of steel rods is better suited to coarse grinding and sand-making applications where excessive fine powder must be limited.
High-Capacity Model Range
Six BMJ models cover nominal capacities from 80 to 500 tph, allowing the mill size to be matched to different feed conditions and production requirements.
Flexible Discharge Control
The discharge configuration can be selected according to the required product size, retention time and throughput. Screening or classification equipment can be added to stabilize the final gradation.
Stable Heavy-Duty Operation
The cylindrical shell, drive system, liners and grinding rods are designed for continuous industrial operation. Proper rod loading, lubrication and feed control help maintain stable output and reduce unplanned downtime.
