摘要： Provided is a method for drying and comminution of moist, mineral raw materials, including at least one of chalk, marl or clay. The moist, mineral raw material is dried and comminuted in a drier crusher while simultaneously supplying hot gases from a kiln system to form a dried material. The dried material in suspended form is directed to a first separator in which the dried material is separated into a coarse fraction and into a fine fraction. The fine fraction is directed to a separation cyclone and then to the kiln system. The coarse fraction is directed to a dosage means. The dosage means directs a first portion of the coarse material to the drier crusher and a second portion of the coarse material to a separate grinding unit where any hard material components, including at least one of flint, sand or marble, are subjected to grinding to form a ground material. At least a portion of the ground material from the separate grinding unit is supplied to the drier crusher. Also provided is an apparatus for conducting the method.

摘要： The aim of the invention is to create a compact circulating grinding plant comprising a product bed comminution roller mill or roller press and a sifter device, in which the problem of mechanically transporting the grinding product that is directed through the circuit is minimized. Said aim is achieved by a circulating grinding plant in which a static cascade sifter is disposed below the gap of the roller press while a subsequent sifter, particularly a dynamic rod basket sifter, is disposed above said roller press. The sifting product discharge area of the static cascade sifter is connected to the sifting air and sifting product inlet of the subsequent sifter via an ascending duct which pneumatically conveys the product.

摘要： The invention relates to a process and an apparatus for grinding and sifting a product, in which the product is embrittled by a coolant and is comminuted in a mill (8), the comminuted product being fed, after comminution while keeping away ambient air and the moisture this involves, to a sifter (14). With the process and the apparatus according to the invention, the product can be comminuted and sifted in a closed-loop process without separating agents having to be fed to the ground product prior to sifting to overcome electrostatic charging. The sifter (14) is preferably operated with the gaseous coolant which is used to operate the mill (8) so that any losses of sifter circuit gas occurring during sifting can be compensated by feeding in a gaseous coolant. The total duration of the process can be reduced considerably.

摘要： An air-swept mill has an annular space with a blade ring between a rotary grinding pan and a casing wall for fluid delivery flow. The annular space and the blade ring form a gas directing or guiding device for rotary flow and circulation flow of the fluid delivery flow. Above the grinding pan, in the vicinity of a classifier, the casing wall is provided with at least one removal device for removing a part of an outer oversize flow, which is formed as a vented concentrated flow substantially directly at the casing wall.
