20110146946 | Method and Cooler for Cooling Hot Particulate Material - A method as well as a cooler for cooling hot particulate material which has been subjected to heat treatment in an industrial kiln, such as a rotary kiln for manufacturing cement clinker may be configured such that hot material from the kiln is directed onto a grate in a cooler where cooling gases via at least one cooling gas duct are directed through slots in the grate for cooling the hot material and where compressed air can be injected into the material on the grate. The method as well as the cooler is characterized in that compressed air is injected into the cooling gas duct. The compressed air which is injected into the cooling gas duct may operate as a non-return valve which can ensure that compressed air is injected into the material on the grate and may prevent clinker dust from falling through the cooling gas duct. | 06-23-2011 |
20110048558 | Device for Dividing a Flow of Lumpy Material into Two Sub-Flows - A device for dividing a flow of lumpy material into two sub-flows comprises a dividing mechanism which comprises a dividing edge for splitting the material flow into two sub-flows, an apparatus for directing the material to the dividing mechanism and an apparatus for diverting the two sub-flows away from the dividing mechanism. The dividing edge can be moved back and forth in its longitudinal direction following its own track. Embodiments of the device can permit the wear on the dividing edge to be more evenly distributed and the service life of the device may thereby be increased. | 03-03-2011 |
