Comparing with the similar function of screw conveyor and belt conveyor, it is characterized by small abrasion, easy maintenance, low

3、consumption, saving material, no noise, good sealing, safe and dependable because of no driving parts when conveying material. It is easy to change direction and multi-point feeding and discharge etc. Therefore it is welcomed by many enterprises.本设备空气斜槽宽为B100B800八种规格，输送物料（水泥）从10800（米/小时）范围内变化，适用于各种大

4、、中、小型企业输送干燥粉状物料之用。 The width of air slide has eight types which are B100 to B800. The range is from ten to eight hundred (m/h). It is widely used to convey dry and powder material in big, middle and small scale enterprise.二、工作原理：. Working principle输送物料时由空气斜槽高端通过斜槽入料口喂入上壳体。压缩空气由专设的鼓风机吹入下壳体，并通过透气层均匀地分

5、布在物料颗粒之间，使物料进行所谓的气体以改变物料的磨擦角使其形成流动状态，沿斜度下滑，通过出料溜子排出，达到输送的目的。When conveying material, feed upper shell from the high side of air slide through the inlet. The compressed air is blown to bottom shell by special blower, distributing lump material by ventilating layer evenly, making material become into

6、the named gas and change abrasive angle of material and become liquid condition, sliding along the slope, discharging from outlet funnel and realize to convey material.三、结构形状及尺寸：. Structure type and dimension空气斜面槽由上、下壳体组成，并沿其输送方向布置成一定的斜面度。斜面槽的上下壳体之间夹有透气层，同时为满足不同输送线路的要求，如转向、改向、清渣、截流等，也设计了相应形状的斜面槽附件。T

7、he inclined surface of air slide is composed of upper and bottom shell, becoming some slope to the conveying direction such as the rotation, diverting, cleaning slag and cut-off etc. And design suitable shape and inclined tank attachment.1、斜槽总长度L包括斜槽附件在内的中心线长度，由工艺决定。1.
