Williams Direct-Fired Roller Mill Pulverizers and Impact Dryer Mills (limestone mills) have proven to be very effective for direct-injection of dry sorbent lime or limestone into the CFB or combustion process. Our experience with CFB technology is extensive and dates back to the mid-1980s during the initial process development stages.
The common intergrinding of limestone and clinker in classical ball mills is there-fore producing a cement of very high surface. The higher the limestone content, the higher the negative impact of its surface on water demand and powder flowability. The intergrinding of Portland-Limestone Cement (PLC) with Vertical Roller Mills avoids excessive ...

One roller typically rotates faster and in the opposite direction to create sheering force. Particle size is determined by the number of rollers, distance between rollers, roller diameter, speed and corrugation pattern. Generally, roller mills grind grain into more uniformly sized particles than hammer mills (Figure 6). Figure 5. Roller mill. Image

Small limestone pebbles will be transferred from the quarry to the lime plant via railcars. The limestone will be dumped into the existing dump hopper at the lime plant and will be conveyed to the roller mill surge bin. The surge bin feeds the two stone and roller mills via screw conveyors. The two mills operate in parallel in the same manner.

slag, fly ash, pozzolanes, limestone etc.). The grinding of the finished cement consumes approximately one third of the total electrical energy of a cement plant. Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further arguments
limestone has an excessive water adsorbtion and separate grinding (ball mill and mixing equipment) is favoured.4 The production of PLC with a Vertical Roller Mill (VRM) is advantageous. A comparison of two ce-ments (CEM II/A-LL 42.5), one ground with a VRM and the other with a ball mill, shows a good perfor-mance of the VRM.
The vertical roller mill has high energy efficiency and the installation space is smaller compared with tube mills. These days, the vertical roller mills have been widely adopted. A）Structure (1) The rollers are hydraulically pressed against a disc table and the feed is ground between the rollers and the disc table.

For limestone grinding, the MPS mill is a proven and well-known machine, which is installed in numerous plants. With the development and introduction of the MVR mill, which was first used in the cement sector, another vertical roller mill is now available, also for limestone grinding. This mill type covers a wide range of throughput rates.
In other mills like vertical roller mills both grinding and drying take place together inside the mill by the hot gases supplied through the mill. The vertical roller mills are usually designed to have a rather constant ratio between airflow and grinding capacity. VRMs of all sizes have the same drying capacities up to 25%.
