摘要： PROBLEM TO BE SOLVED: To economically enhance the abrasion resistance of the surface of the side plate of a rotor used in a vertical rotary centrifugal lump crushing apparatus. SOLUTION: When an abrasion-resistant metal is applied to the surface of the side plate 12 of the rotor 10 by weld padding, a placing material 20 the abrasion resistance of which is more excellent than that of a welding wire 30 is placed on the surface of the side plate 12 and weld padding is applied to the surface of the side plate 12 from the upside of the placing material 20. The placing material 20 is melted and the build-up hardened metal is thickened by the chemical components of the placing material to be enhanced in its abrasion resistance.

摘要： PROBLEM TO BE SOLVED: To efficiently carry out muck by reducing an idle time until muck is loaded onto the next truck after muck is loaded onto a truck in the carrying- out method for muck by a muck loader. SOLUTION: A chute 12 in which an endless belt is installed onto a roller conveyor is arranged on the discharge side of a conveyor 2 for the muck loader in a vertically inclinable manner. When muck is carried out, muck falling from the discharge end of the conveyor 2 is loaded onto a truck 3 standing by on the discharge side of the chute 12. An empty another truck 3' is made to stand by in parallel until loading to the truck 3 is completed, and the chute 12 is tilted in the opposite direction and muck is loaded successively onto the truck 3' when loading to the truck 3 is completed.

摘要： PROBLEM TO BE SOLVED: To enhance crushing efficiency, promote energy saving, and decrease running time by installing a crushing blade projecting from the outer surface of a rotor and by using a crushing blade for crushing a material discharged from the rotor. SOLUTION: A material to be crushed (e.g. a mineral) charged into a rotor 1 from a charge port 14 is discharged from a discharge port 15 by a centrifugal force generated by the rotation of the rotor 1 and is crushed by causing it to collide with a crushing body (e.g. a dead bed) formed in the surroundings. At this time, the material rebounding without being sufficiently crushed, the material insufficiently accelerated, or the material flying in the changed direction is effectively crushed by beating it with a crushing blade 3 projecting from the outer surface of the rotor 1. The material beaten and crushed with the blade 3 is crushed again by causing it to collide with a dead bed or the like in the surroundings by the striking force of the blade 3. Therefore, even a material insufficiently crushed with the blade 3 can be crushed without fail.

摘要： PROBLEM TO BE SOLVED: To feed liquid to be treated to a strongest portion of a centrifugal force in a treating space, to allow the solids to settle and to make efficiency remarkably high without requiring to impart excessive rotational speed by constituting the liquid to be treated so as to be fed into the treating space in the vicinity of the inside surface of an outer cylinder. SOLUTION: Suspension liquid is fed into the treating space 5 between the outer cylinder 1 and the inner cylinder 2 through a liquid flow path 4 of a hollow rotary shaft and is affected strong centrifugal force by high speed rotation of the inner and outer cylinders 2, 1. Thus, the solids settle on the inside surface of the outer cylinder 1, become condensed sludge, are conveyed with a screw blade 3 and discharged from a discharge port 6 at one end of the outer cylinder 1. Separated liquid settled the solids and became clarified liquid is discharged from a discharge port 7. In this case, because a feed disk 8 is arranged at the tip 4' of the liquid flow path 4, the liquid to be treated is guided to the inside surface of the outer cylinder 1 along the feed disk 8, and certainly passes through a portion under the strongest centrifugal force and while it is affected by a sufficient settling force, enters the treating space 5 and further here receives the settling force.

摘要： PROBLEM TO BE SOLVED: To prevent deformation of a letter by providing at least one place each of a region of small elongation in and a region of large elongation respectively in the longitudinal direction on a band type knob cover made of synthetic resin and indicating an advertising letter, etc., on a part of small elongation. SOLUTION: A band type knob cover 1 to be used by winding it around a door knob for antislipping, antibacterial purpose, decoration, etc., is formed of synthetic resin by a metal mold by integrating a central region 12 of small elongation and end part regions 11, 13 of large elongation with each other. Additionally, in case of giving an antibacterial property to the knob cover 1, it is done by molding the knob cover 1 by mixing an antibacterial agent in material resin, applying the antibacterial agent on the inside surface of the metal mold, spraying the antibacterial agent after molding or other methods. Additionally, in case of indicating an advertising letter, etc., it is done by printing or adhering a seal on the region 12 with small elongation so as not to deform the letter, etc. Thereafter, the knob cover 1 is wound around the knob, the end part regions 11, 13 are elongated, a projection 11a is inserted into a hole 13a and adhered closely to it. Consequently, it is possible to display a function of the knob as an advertising medium.
