Rod mills are mainly used for primary grinding of crushed ore with a particle size range up to 50 mm for soft materials, and between 20 and 30 mm for harder materials where a narrow product size distribution is required (e.g. for subsequent gravity separation).
The rod mill is loaded with the grinding media of steel bars. It consists of five parts including cylinder shell, feeding system, discharge system, main bearing and transmission system.
It is available for both of the dry grinding and wet grinding fashion as the customer’s needs.
By using a new advanced technology of inlet and outlet control, we can match the befitting grinding media according to your material property, which will make the discharge size well distributed.
The grinding process is typically a combination of breakage and classification aspects, which indicates that “the most energy efficient breakage system would be the one where the particles leave the energy field as soon as they become smaller than the required product size”.
While designing and selecting grinding mills, we does extensive studies on material transport issues to ensure an efficient material transport system, thus greatly enhancing the energy efficiency and capacity of horizontal grinding mills.
Energy Saving
Compared with the sliding bearing of the old rod mill, our new equipment can save you 10-20% energy in total. The production is improved more than 10% than usual.
Good Discharged Particle Size
The experienced technology design on the specification can promise you a well running situation with less over crushing problem.
Good at Wet Grinding
We have supplied numberless of wet grinding rod mills for customer in coal chemical industry, to deal with the coal and petroleum coke material and prepare for the coal water slurry making.
Wet Overflow Discharging Design
The mill can design as the first level open circuit grinding equipment, which can be widely used in the department of manual stone sand, ore treatment plant and chemical plant, etc.
