The system for drying lignite according to the present disclosure includes a mill configured to crush the lignite; a dryer configured to receive crushed lignite from the mill, to dry the lignite by heat-exchange with steam and to discharge dried lignite; a condensing-precipitating evaporator in fluid communication with the dryer so as to receive vapor which is evaporated when the lignite is dried, and which is discharged from the dryer. The evaporator is configured to condense the vapor discharged from the dryer by heat-exchange with water. The coal dust contained in the vapor is precipitated into a condensed aqueous solution when the vapor is being condensed, and the condensed aqueous solution is discharged. The system includes a Mechanical Vapor Re-Compression (MVR) configured to receive steam generated from the condensing-precipitating evaporator, to compress the steam into superheated steam, and to supply the compressed superheated steam to the dryer.

To treat organic sludge while keeping facility costs, cement production efficiency, and a reduction in clinker production amount to a minimum. An organic sludge treatment device includes: a fractionation device 7 that fractionates a preheated raw material R2 from a preheater cyclone 4C excluding a bottommost cyclone of a cement burning device 1; a mixing device 8 that mixes an organic sludge S with the fractionated preheated raw material, and that dries the organic sludge using sensible heat of the preheated raw material; and a supply device (mixture chute 12, double-flap damper 13, shut damper 14) that supplies a mixture M from the mixing device to a calciner furnace 5 of the cement burning device or to a duct disposed between a kiln inlet portion of a cement kiln 2 and the calciner furnace. The treatment device may be provided with an introduction device for introducing an exhaust gas G2 including dust, odor and water vapor from the mixing device to a gas outlet of a bottommost cyclone 4A of the cement burning device.

A system and method for drying and utilizing spent grain includes an agitation device having an elongated semi-cylindrical mixing chamber with a motor-driven shaft and a plurality of agitators. A lid is hingedly positioned along the top end of the chamber and is connected to the dehumidification system by a pair of air ducts. An air filtration device is interposed between the air output of the agitation device and the air input of the dehumidification system. A method of drying spent grain includes the steps of pouring spent grain into the interior space of the chamber, securing the lid in the closed position, agitating the grain inside the chamber via the agitators, removing damp air from the interior space of the chamber, and introducing dry warm air to the interior space of the chamber until a moisture content of the spent grain achieves a user specified level.

A batch sample preparation apparatus (10) for preparing a geological sample for analysis is described and claimed. The apparatus (10) comprises a dryer (12) having a drying (chamber 52), a sample inlet (20) and at least one sample outlet (22), (24) communicating with the drying chamber (52), to a comminution device (14) in selective fluid communication via valves (26), (28) with the dryer (12) to selectively receive dried sample. The apparatus (10) has a source of fluid (74) introduced at the dryer (12) so that sample material may be transported from the dryer (12) to the comminution device (14) by fluid flow, which fluid flow also extracts the sample material from the comminution device (14) for collection and subsequent analysis.
