摘要:
A vertical mill for material such as cement raw materials, clinker, coal, or the like comprises a grinder portion which has rollers arranged to grind the material by their rolling on a rotary table, a separator means which is positioned above the grinder portion and which classifies the ground material conveyed pneumatically from the grinder portion to the separator means by the two opposite forces of centrifugal force of a rotary disk and of fluid resistance of a vortex flow, a plurality of straightening vanes which are mounted between the casing and the inner cone and which adequately regulate the direction of the fluid in the lower portion and in the upper portion in passage between the grinding portion and the separator means, and a casing outside the separator means having the appropriate shape for forming a horizontal vortex flow in the separator means. The aforesaid vertical mill structure improves the classifying efficiency of the separator means.

An air classifier comprises a casing formed of a generally hollow cylindrical vertical casing body and an inverted conical hopper fixed to the lower wall of the casing body. A fine product outlet duct is provided at the center of the upper wall of the casing body. An air-powdered material inlet duct and a secondary air inlet duct are set in the diametrically opposite positions of the vertical wall of the casing body to project tangentially outward. A vertical rotary shaft extends through the central portion of the casing body. A rotary disc member for concurrently carrying out the dispersion and classification of a powder raw material is fitted to the lower end of the rotary shaft at a boundary between the casing body and hopper. A cage-shaped assembly of guide vanes is provided in the casing body to conduct a mixture of air and powdered material into the casing body. The air classifier of this invention constructed as described above can precisely classify by itself a large amount of powder material as a classifier for swept-air from a mill.

An ion generating device generates O2−(H2O)n (where n is a natural number) as negative ions and H+(H2O)m (where m is a natural number) as positive ions, and discharges those ions into the air so that airborne germs are killed through an oxidation reaction by hydrogen peroxide H2O2 or radical hydroxyl OH generated through as an active species a chemical reaction between the negative and positive ions. Satisfactory sterilization is achieved when the negative and positive ions are generated in such a way that the concentrations of the negative and positive ions are both 10,000 ion/cc at a distance of 10 cm from the point at which they are generated.

摘要:
A desired number of cables are drawn, along with the falling charge, into a blast furnace from its top and the forward ends of the cables are melted upon reaching the melting zone in the furnace. The length of each of the cables to its melted end is measured in accordance with the result of a voltage pulse response measurement utilizing the distributed constant circuit characteristics of the cable, and the height level of the melting zone inside the furnace is measured from the cable length by correcting it for the amount of deflection of the cable within the furnace. By measuring the cable length at each of a plurality of radial locations of the furnace, it is possible to estimate the three-dimensional shape of the upper boundary of the melting zone with a high degree of accuracy.
