Spiral classifier is one of the equipment of ore dressing, spiral classifier with different proportion of solid particles in liquid precipitation, principle and therefore different speeds, equipment for mechanical grading. To mill within the material powder level in filter, and then the coarse material by using spiral plate rotary piece is screwed into the mill feed port, the fine filter out from the overflow pipe. Spiral classifier referred to as classifier. Produce high weir type single screw and double helix, submerged single helix and double helix four grader. The classifier is widely applicable to the concentrator and the ball mill with a closed cycle process split shunt mineral sand, or used in gravity concentrator to grade ore and fine mud, for size grading of ore dressing process and metal, desliming, dehydration and other operations and ore washing operations in the. The classifier is widely applicable to the concentrator and the ball mill with a closed cycle process split shunt mineral sand, or used in gravity concentrator to grade ore and fine mud, for size grading of ore dressing process and metal, desliming, dehydration and other operations and ore washing operations in the. The classifier has the characteristics of simple structure, reliable work, convenient operation and so on. Working principle: classifier: classifier is with the aid of solid particle of different size, different proportion, the principle of settling velocity in fluid of different, fine mineral particles floating in the water will overflow from the coarse ore, grain sink on the bottom of the channel. By a spiral to the upper discharge, to mechanical classification a classification equipment, can take out the mill within the powder level to the filter, and then the coarse material by using spiral plate rotary piece is screwed into the mill feed port, the fine filter out from the overflow pipe. The machine base adopts channel steel, the body adopts welded steel plate. The spiral shaft into the head, spindle, use the pig iron, durable, lifting device is divided into two kinds of electric and manual. see more images and information about Industrial Milling machines and vibrating screen design specification,vibrating screen filter design specification ,visit this website:http://www.mobilecrushermachinery.com/portable-crushers/vibrating-screen-design-specification.html
