Rolling Machine

Description of Rolling Machine:
Our rolling machine is a kind of new-type cement grinding equipment developed on the basis of advanced technology, and its grinding system has integrated the rolling, scattering, separating, drying and powder separating into one body. Besides, when used together with a ball mill, it can be used in various process flows, like pre-grinding, mixing, semi-finished grinding, finished grinding, and more.

Due to the change in its grinding principles, this rolling machine and its grinding system have more advantages, like 50-100% lower power consumption, and 100-300% higher productivity.

Features of Rolling Machine:
1. Heat overlaying weld has been employed to make the maintenance of wear-resisting layer more convenient. Meanwhile, the amount of microcracks is largely reduced, and the service life of roller surfaces is no less than 8000h. It is quite easy to maintain the roller surfaces.
2. Aeronautic hydraulic technique is used to make the hydraulic system more reliable and stable.
3. With the cooperation of its hydraulic system and automatic control system, it can do the work of load control of main driving motor, deviation control of space between rollers, automatic deviation adjustment, and fault diagnosis.
4. Its matched powder separator has scattering, grading and drying capacity, which makes low operation costs and high working efficiency possible.
