Raymond Roller Mill for Cement Grinding
The cement Raymond Roller Mill (R-Series Roller Mill) is mainly used for the powder production of cement clinker. In recent years, as the Raymond mill design and technology improve, it has been using for cement grinding all around the world. In addition, it is also used in other mineral industries with its diverse applications.
Mill parameter of R type
Grinding roller is the main component for rolling and grinding raw materials. There are 2-6 grinding rollers in the mill. Each of grinding rollers is installed on the same shaft and rotates at different speeds.
Note: The above parameter take the processing of limestone as an example for reference, due to the different properties of different materials, the parameter would be different in practice, the above data replaces the reference.
Main structure
The R-Series Roller Mill is mainly composed of main mill, feeder, classifier, blower, pipeline device,storage hopper, electronic control system, and a collection system. The main mill including mill base, central shaft frame, grinding ring, star rack assembly, grinding roller assembly, central shaft, blade holder, blade holder assembly, and cover tube, etc.
The grinding rings and rollers are made of special abrasion-resistant materials and their contact surfaces have been processed for abrasion-resistant. The power device of the system can choose from reducer transmission or double transmission. The classifier uses a mandatory turbine classifier, and the feeding system can be equipped according to different materials. The collection system can be a closed-circuit collection system with double cyclone and pulse dust collector, or an open-circuit system with full pulse collection. The control system can be automatic control mode, or remote control mode according to customers’ needs.
Advantages
Compared with the ball mill, the Raymond roller mill has the following characteristics:
High grinding efficiency; large drying capacity; large material volume, large and medium Raymond mills can dispense with secondary crushing; stable chemical property of final product; evenly particle distribution, which is contribute to calcinate. The process is simple; minimum noise and dust, clean operating environment; less metal loss, high utilization rate.
