摘要： PURPOSE: To achieve the high efficiency by forcibly rotary-driving a grinding roller by a driving means at a speed at least coincident with a theoretical speed when the grinding roller is engaged with a grinding pan by friction in the same direction as the grinding pan regardless as to whether or not a material to be ground is present. CONSTITUTION: A roller mill having at least one the grinding roller 20 in the standstill state is provided, allowing the grinding roller 20 to be elastically pressed against the rotating grinding pan 61. Further, an integrated classifier 11 is arranged above the roller mill, thereby allowing the material to be ground and an air mixture to be substantially supplied to the grinding pan 61 and the grinding roller 20 from the center of the roller mill. Then, the grinding roller 20, too, is provided with a driving means 26 being a separate body in addition to the grinding pan 61. By this driving means 26, the grinding roller 20 is forcibly rotary-driven at a speed at least coincident with a theoretical speed when the grinding roller 20 is engaged with the grinding pan 61 by friction or a higher speed than this theoretical speed in the same direction as the grinding pan 61 regardless as to whether or not the material to be ground is present.

摘要： PURPOSE: To remarkably prolong the service life of a grinding roller, reduce the necessity for a repair and manufacture the grinding roller by a simple method with a high cost effect in particular. CONSTITUTION: In a grinding roller for a roller mill or a rolling mill and its manufacturing method, a roller jacket 7 is manufactured in one piece for mounting on a radially inner roller body 3 for increasing the service life at a limited manufacturing cost. The roller jacket 7 has rated breaking points 10, along which the roller jacket 7 breaks into a plurality of segments with radially directed breaking faces in the event of a corresponding stressing. Both the roller jacket 7 manufactured in one piece and the optionally formed roller jacket breaking segments are fixed in an operationally safe manner by means of a holding device 20.

摘要： PURPOSE: To constitute a roller mill air classifier for planning improvement of efficiency of the energy requirement of the whole plant to drastically reduce a gas flow rate by the design. CONSTITUTION: A central rising vessel 1 formed taper-shaped to the mill case and raising a gas grinding material flow is deflected outside toward down-flow in the upper part of a classifier rotor 5. A classifying chamber 12 includes a louver 4 extended toward the classifying rotor 5 in its inside. Gaseous minute material flow from the outside to the inside through the classifying rotor 5 is made to flow down via a bottom opening of the classifying rotor 5 surrounding the central rising vessel 1 to turn to a falling axis around the rising vessel. While coarse material is made to flow down via a return line apart from the rising vessel and returned to the mill case. The rising vessel 1 is disposed in the center, so the usual energy requirement for suction of the grinding material particles are saved by guiding the gross material and grinded material from the classifying chamber 12 to the outside return line or a draw off pipe by the separated routes, and deflecting downwards a carrier gas grinded material flow at the upper part in the classifier 10.

摘要： PROBLEM TO BE SOLVED: To provide a mill gear that can be used for roller mills with a mechanism for turning a crushing roller on a crushing pan, is applicable to any roller mills regardless of their particular sizes and rated capacity, can reduce cost for members and shorten the delivery period, and exerts appropriate load distribution. SOLUTION: A bevel-gear wheel step 10 receives motive energy and then the energy is supplied from one or a plurality of planetary wheel steps 5 to a crushing pan. A driving port of the bevel-gear wheel step 10 is not a single large driving port unit, but is comprised of a plurality of individual driving ports 11 and 12. When rotative power is supplied to the individual driving ports 11 and 12, the rotative power is transmitted to the corresponding bevel-gear pinions 15 and 16. The rotative power of the bevel-gear pinions 15 and 16 is transmitted to the vertical drive shaft 21 via the bevel-gear wheel 20 to be engaged therewith, and then further transmitted to the planetary wheel step(s) 5 via a connector 22.

摘要： PURPOSE: To provide a crushing method in which energy consumption per crushing ton of crushing material is minimized and also throughput is increased and a device therefor. CONSTITUTION: Grinding rolls 7 rolled by independent driving or frictional resistance are arranged on a grinding face 5. A classifier 29 having a classifying rotor 24 is arranged integrally with a pulverizing and classifying chamber 8 surrounded by a casing wall 15 above the grinding rolls 7. Materials of different grain sizes to be ground are fed onto the crushing face 5 as a charge material 10. Between the casing wall 15 and a grinding pan 6, an annular space 14 is formed. In the annular space 14, a blade ring 16 is arranged to form an annular gas direction control device 19. Therefore, by the formed flow passage 20, a discharge action is applied to a feeding flow 9 of gas. Since the blade ring 16 is arranged at an angle in the tangential direction, streams 21, 22 circulating while rotating are generated near the casing wall 15 to take grinding material particles 13 into a vented concentrated stream 17.
