    摘要： A circular disc element having at least two beam elements. Each beam element extends beyond an outer circumference of the circular disc element in an extension direction which is parallel to a radial direction of the disc element. The circular disc element further includes at least two holes extending through the circular disc element in a longitudinal direction which is substantially perpendicular to each of the extension directions with respect to a circumferential direction of the circular disc element, which circumferential direction corresponds to the outer circumference of the circular disc element. The circular disc element can function as a grinding means in a grinding process for grinding slurry.

    摘要： A device for producing expanded granulated material from mineral material in the form of grains of sand with an expanding agent includes a furnace with a furnace shaft, having an upper end and a lower end. A conveying section extends between the two ends and passes through a number of heating zones arranged separately from one another in a conveying direction. The device also includes at least one feeder in order to charge at least the unexpanded material into the furnace shaft at one of the two ends in the direction of the other of the two ends. At least one directing element is at least partly arranged in the furnace shaft and forms a gap with an inner wall of the furnace shaft, at least in the region of one of the two ends. The at least one feeder is designed for charging the material into the gap.

    摘要： A curable elastomer composition includes a crosslinkable polymer, and a filler selected from surface-reacted calcium carbonate, precipitated hydromagnesite, or a mixture thereof, wherein the surface-reacted calcium carbonate is a reaction product of natural ground calcium carbonate or precipitated calcium carbonate with carbon dioxide and one or more H3O+ ion donors, wherein the carbon dioxide is formed in situ by the H3O+ ion donors treatment and/or is supplied from an external source. Furthermore, the disclosure relates to a cured elastomer product formed from said composition, an article including the cured elastomer product, a method of producing a cured elastomer product, and use of the filler for reinforcing a cured elastomer product.
