    • A method for heating powder material comprising the steps of allowing hot gas from a plurality of hot gas sources separate from each other to flow separately through a plurality of hot gas passages which include a plurality of dust collectors and ducts for connection between said dust collectors, separately charging raw material to be heated through the each duct leading to the dust collector located in the uppermost part of said respective hot gas passages, then uniting the charged powder material, then alternately wandering the united powder material from one hot gas passage to the other hot gas passage, thereby the united powder material is heated by heat exchanging with the respective hot gas streams, and finally discharging the heated powder material through the duct located below the lowermost dust collector. An apparatus is provided for carrying out the aforesaid method comprising a plurality of hot gas passages through which hot gas streams coming from a plurality of hot gas sources separate from each other flow, said hot gas passages consisting of dust collectors and ducts for connection between said dust collectors, raw material ducts for connection of the dust collector disposed in one of the hot gas passages to the duct disposed in the other one, and raw material feeders arranged for the respective hot gas passages.
    • 一种用于加热粉末材料的方法,包括以下步骤:允许来自彼此分离的多个热气源的热气体通过多个热气体通道分开流动,多个热气体通道包括用于所述集尘器之间连接的多个集尘器和管道, 分别将通过各导管通过各个热气体通道的最上部的集尘器的每个导管加热的原料进行加料,然后使带电的粉末材料结合,然后将联合粉末材料从一个热气体通道交替到另一个热气体通道 热气体通道,通过与各个热气流的热交换来加热联合粉末材料,最后通过位于最下面的集尘器下方的管道排出加热的粉末材料。 提供了一种用于执行上述方法的装置,其包括多个热气通道,来自多个热气源的热气流彼此分离通过,所述热气通道由集尘器和导管组成,用于连接在所述 集尘器,用于将设置在一个热气体通道中的集尘器连接到设置在另一个热交换器中的管道的原料管道,以及布置用于各个热气体通道的原料进料器。
