The invention relates to a roll mill having at least one pair of grinding rollers bearing against a substantially horizontal surface of a grinding table which is rotatable about a vertical axis. The rollers are mounted at one end of a roller support the opposite end of which is guided by guide lugs slidable vertically in guides and linked to the roller support by a tension rod.
mills. With the exception of coal mills, MPS mills are equipped with an external material feed system to reduce pressure losses. Thanks to the optimal design of the nozzle ring, a fluidized bed above the nozzle ring is still used for highefficiency drying of the raw material, even at reduced gas speeds of 4050 m/s.

Vertical Roller Mill Coal Pulverizers Typical design of vertical roller mill coal pulverizer Bearing Position Representative Example 1 Representative Example 2 Representative Example 3 Crusher Roller Fixed Side DoubleRow Tapered Roller Bearings (#248;320 #215; #248;620 #215; 280) Combined Tapered Roller Bearings (#248;480 #215; #248;950 #215; 440)
A cement plant requested assistance installing a 480 mm bore cylindrical roller bearing and a 480mm bore double row tapered roller bearing set for their vertical roller mill wheels. NSK was on site to measure initial clearance, make recommendations on spacer grinding, and measure final clearance to ensure the bearing was installed with proper methods and clearances.
Vertical roller mills (VRM) can replace ball mills or tube mills used for preparing coal. Today VRMs with capacities up to 50 tph are the dominant technology for coal grinding. According to MIIT, grinding media wear in a VRM will only be 5 to 10 g/ton of coal powder, as compared to 100 g/ton of coal powder in a ball mill.
Vertical roller mill is a kind of grinding machine for cement, raw material, cement clinker, slag and coal slag. It has the features of simple structure and low cost of manufacture and use. Vertical roller mill has many different forms, but it works basically the same.

Krupp Vertical Roller Coal Mill Bearings. Ball mill is a cylinder rotating at about 7080 of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills Grinding media consists balls of 34 sizes 60mm30mm in designed proportions with large sizes in feed end and small sizes in discharge end
Roller Mils are directly driven bevelwheel planetary gears or bevel cylindrical gear units. The gear unit represents an almost integral component of the mill. The output flange of the gear unit is rigidly connected with the grinding table. In addition to transmitting the torque,the gear unit also has capability to take up the reaction forces from the the griding force of the mils rollers.
The roller mill 1 illustrated in the drawing can for example be a spring roller mill, but naturally other suitable forms of the actual roller mill, ball ring mill, could also be used. The roller mill 1 essentially comprises a lower grinding part 2 with a mill housing 3 and a sifter part 4 placed ( flanged) on this grinding part with an outer sifter housing 5.
Today the airswept vertical roller mill is the standard solution for coal grinding installations. And thanks to our continuous refinement of the ATOX coal mill over the years, todays leading airswept vertical roller mill is the compact ATOX. Offering high reliability,
