摘要： In a method of the magnetic loading of a sintering material, magnetically susceptible sinterable substances of high magnetization and fine substances of slidable dropping at low speed are segregated in great amounts in an upper portion of a sintering material layer deposited on a pallet. More of magnetically susceptible sinterable substances such as mill scale, returned ore and the like of good magnetic attachment and fine substances of low drop speed are caused to be segregated in the upper portion of that layer. A magnetic force is applied to a starting sintering material, during movement of the latter having been facilitated in its particle size segregation on a sloping chute, by use of a cylindrical magnetic drum having built therein a permanent magnet and disposed downwardly of the sloping chute.

摘要： A method of charging coal into a chamber furnace-type coke oven. The coal is fed from a table feeder from a coal hopper so as to be dropped and charged into a carbonization chamber of the coke oven, through a charging cylinder. The coal fed from the table feeder is accelerated by rotation vanes at the initial stage in which the coal starts to drop. The vanes have a rotation center which is located upward on the exterior of a locus of the stream of free fall gravitated by the coal. The rotation speed of the vanes is progressively increased in the latter half of charging of the coal. The coal is thus allowed to accumulate in the carbonization chamber so that the bulk density of the coal in the vertical direction can become uniform. Also disclosed is an apparatus for charging coal into a chamber furnace-type coke oven. The apparatus includes a coal hopper for storing the coal therein. A table feeder feeds the coal from the hopper. Rotation vanes increases the speed of the coal fed from the feeder at the initial stage in which the coal drops from the feeder. The vanes have a rotation center which is located upward on the exterior of a locus of the stream of free fall gravitated by the coal. A charging cylinder guides the coal, which has been accelerated by the vanes and dropped into the carbonization chamber.
摘要翻译：将煤装入室式炉式焦炉的方法。煤从台式进料器从煤斗进料，通过加料圆筒落下并装入焦化炉的碳化室。在煤层开始下降的初始阶段，由台式给料机供给的煤料被旋转叶片加速。叶片具有旋转中心，该旋转中心位于由煤引起的自由落体流的轨迹的外部上方。煤炭的后半部分叶片的转速逐渐增加。因此，煤被允许积聚在碳化室中，使得煤在垂直方向上的堆积密度变得均匀。还公开了一种用于将煤装入室式炉式焦炉中的装置。该装置包括用于在其中储存煤的煤斗。台式给料机从料斗中供给煤。旋转叶片增加了煤在从进料器落下的初始阶段从进料器供给的煤的速度。叶片具有旋转中心，该旋转中心位于由煤引起的自由落体流的轨迹的外部上方。一个充气筒引导煤被叶片加速并落入碳化室。
