Solid particulate material such as cement raw material, clinker, etc., is finely ground, crushed or pulverized, by means of a rotatable generally vertically oriented container of generally inverted frusto-conical shape, and having grinding media such as steel balls disposed therein. The discrete particles of the material to be pulverized are fed into the upper part of the container as it is rotated about a central vertical axis, and egress of the resulting finely ground material by centrifugal force from the container to external collection is accomplished by the provision of slits in the inclined side wall of the rotary container. A fixed cover enclosing the upper part of the container is provided with inner guide vanes which are typically curved or of a vortical form. A preliminary coarse crushing mechanism may be provided, and this mechanism may be integrated with the rotary container, so that coarse crushing and fine crushing may be performed by a single device.

Pulverizing mill apparatus

A heat exchanger including a separating chamber in the form of a prism having a substantially horizontal center axis and axially elongated. The separating chamber having a collecting chamber disposed beneath it has an inlet duct opening in the separating chamber and connected to one wall of the separating chamber, and an outlet duct opening in the separating chamber and connected to a wall of the separating chamber. The outlet duct may be connected to the wall to which the inlet duct is connected or to another wall parallel to the wall to which the inlet duct is connected. The inlet duct is positioned and oriented in such a manner that a stream of gas and particulate material is introduced therethrough into the separating chamber in a direction tangential to a spiral stream of gas and particulate material formed in the separating chamber, and the outlet duct is positioned and oriented in such a manner that a stream of gas is discharged therethrough from the separating chamber in a direction tangential to the spiral stream of gas and particulate material formed in the separating chamber. The collecting chamber is disposed away from the spiral stream of gas and particulate material formed in the separating chamber.
