A blower (100) blows inert gas. A crusher (200) repeats vitrifying plural kinds of inorganic compounds (A1) by mechanical energy and blowing up the plural kinds of vitrified inorganic compounds (A1) by the inert gas blown from the blower (100). At least some of the plural kinds of inorganic compounds (A1) blown up by the inert gas enter into a first collector (300). The first collector (300) returns the at least some of the plural kinds of inorganic compounds to the crusher (200). A system (S) (for example, a pipe (Pa), a buffer tank (110), a pipe (Pb), a pipe (Pc), and a pipe (Pi) described below) circulates the inert gas from the blower (100) through the crusher (200) and the first collector (300) to the blower (100).

Apparatus for distributing a solid, gel, powder, granular, liquid or viscous liquid test substance in an extraction fluid comprises: a) a flow cell for holding the test substance comprising an extraction chamber of uniform cross-sectional area, a grinding surface, an extraction fluid inlet and an extract outlet; b) a grinding head disposed within the extraction chamber and adapted to reciprocate therein; and c) a recirculating pump for driving extraction fluid: (i) into the flow cell via the extraction fluid inlet; (ii) through the extraction chamber; and (iii) back to the flow cell via the extract outlet.

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.

The invention is directed to a glass disposal system. A device (10) for breaking glass articles is provided, which comprises an inlet (12) and an outlet (26) in fhrkl communication with one another and having a rotating member (16) interposed therebetween. The rotating member (16) is attached to, and capable of being rotated by, a motor (24). The inlet (12) to the device (10) opens onto the rotatable member (16) and the outlet (26) is substantially tangential to the rotatable member (16). The rotatable member (16) comprises portions to create an overall flow of air from the inlet (12) towards the outlet (26), and subsequently expels the particles of the broken object away from the rotatable member (16) through the outlet (26). The invention extends to a conduit (60) for the system.
