球磨机是一个圆形筒体,两端有端盖,端盖连着轴颈支承在基座上。一端为进料,另一端为出料。在出料端盖装有齿轮并连接传动装置。筒体内装入一定量的适当规格的研磨体(一般为钢球或钢段)和被磨物料,其加入量通常为筒体有效容积的25%~45%,当电动机通过齿轮带动筒体回转时,磨内钢球和物料在磨擦力和离心力的作用下将被带动作相应的弧形运动。当磨机转速达到一定的速度(即工作转速)时,物料和钢球的混合物将被带到筒体的上部,在接近顶端的位置上,由上向下抛落或泻落,从而对下部物料进行冲击、研磨和辗碎。磨细的物料通过磨机出料端的格子板、扬料板和轴颈内的出料螺旋卸入出料罩的圆筒筛内过筛卸出。
球磨机按筒体长度分为短筒、长筒、管磨和锥形等多种;按内部结构分为单仓和多仓;按传动方式分为周边传动和中心传动;按排料方式分为溢流排料和格子排料等多种形式。粉煤灰加气混凝土厂多使用单仓(或两仓)管磨机,这种磨机适用于入料粒径较小、硬度不大、出料细度要求较高的物料,非常适合加气混凝土的物料特点。
由于球磨机在磨细过程中有混合作用,可将石灰和石膏混合磨细,运转可靠,维修工作量小,物料磨细度符合加气混凝土生产的需要,成为首先的磨细设备。
Ball Mill
Ball mill is a circular cylinder, both ends of the end caps,, the dosage is usually effective cylinder volume of 25% to 45% when the motor rotating cylinder driven by gear when the ball mill and the material in the friction and centrifugal force will be led for the corresponding arc movement. When the mill speed reaches a certain speed (ie, the working speed), the mixture of materials and the ball will be brought to the upper cylinder, near the top position from the drop down into the falling or diarrhea, and thus lower materials to impact, grind and shredded. Finely ground material through the mill discharge side of the grid plate, lifting plate and the material within the spiral journal unloading material into and out of cover within the cylindrical sieve sieve unloading.
Divided by shell length ball Duantong, long-barreled, tube mill and conical variety; according to the internal structure is divided into single-chamber and multi-warehouse; transmission by transmission mode is divided into peripheral and central transmission; by way of discharge into overflow discharge and grid nesting and other forms. Fly ash aerated concrete plant to use more single-chamber (or two positions) tube mill, the mill feed particle size for smaller, less hardness, the fineness of the material require a higher ideal for added characteristics of gas concrete materials.
As the ball there in the process of mixing finely ground, can be finely ground mixture of lime and gypsum, reliable operation, maintenance workload of a small, pulverized material degree of aerated concrete production line needs to become the first of the finely ground equipment.
