立磨

 

一、總論
    立磨屬于輥式磨的一種，按照要求可以配置2, 3或者4個(gè)磨輥。每一個(gè)磨輥，它都是由固定的搖臂、安裝搖臂的支架，以及液壓系統(tǒng)組成了粉磨的動(dòng)力單元。此動(dòng)力單元為整體式或者一個(gè)標(biāo)準(zhǔn)組件，它可在磨盤周圍布置成二組分、三組分或者四組分。

I. Overview
    SH vertical mill is one of the roll mills. It can be equipped with 2, 3 or 4 grinding rolls. Each grinding roller is composed of fixed rock arms, frame and hydraulic pressure system, which is the drive unit. This drive unit is an integral or standard part. It can be mounted around the grinder to be two-component, three-component or four-component.

二、工作原理
    原料通過自動(dòng)進(jìn)料裝置進(jìn)入到下料管，下料管是透過分離器的側(cè)面或中間進(jìn)入到磨機(jī)內(nèi)部的。物料借助于重力和氣流的沖擊作用而落到磨盤中央。磨盤牢固的與減速機(jī)相連，以恒速旋轉(zhuǎn)。磨盤的恒速旋轉(zhuǎn)將粉磨物料均勻的水平分布在磨盤的襯板上，液壓系統(tǒng)的強(qiáng)大壓力通過搖臂傳遞到磨輥，并由自動(dòng)控制系統(tǒng)保證磨輥能保持恒定壓力，斜錐式的磨輥結(jié)構(gòu)能夠咬住物料，在與磨盤相對(duì)運(yùn)動(dòng)的過程中 將物料碾碎，并在碾壓與磨擦運(yùn)動(dòng)的共同作用下將物料碼成粉末。在離心力的作用下，被磨碎的粉料 向磨盤邊緣甩出，與進(jìn)入磨機(jī)的高速熱氣流混合并進(jìn)行充分的熱交換，水份被迅速蒸發(fā)，跟隨熱氣流 上升的粉料水份已不超過1%,不斷進(jìn)入磨機(jī)中部的物料也在離心力的作用下不斷向磨輥的碾壓軌跡區(qū) 運(yùn)動(dòng)填補(bǔ)被甩出物料的空間，行成物料順序流動(dòng)。被高速氣流帶動(dòng)上升的粉料進(jìn)入分離器進(jìn)行分選，分選出的合格粉料被送入收塵器回收入庫(kù)，不合格的粉料被分離器轉(zhuǎn)子葉片甩出與外靜葉片碰撞，使其動(dòng)能衰減，落回磨盤中進(jìn)行再粉磨。形成了粉磨過程的動(dòng)態(tài)循環(huán)作業(yè)。

II. Working principle
    The raw material goes into the tremie pipe through the automatic feeder. The tremie pipe extends into the inside of the mill through the concentrator’ s side or center. The material drops on the center of the grinder with the help of the force of gravity and the gas impact. The grinder is firmly connected to the speed reducer, spinning at a constant speed. The grinder’ s constant speed spinning scatters the material evenly on the plate of the grinder. The strong pressure of the hydraulic pressure system is transmitted to the grinding roll through the rock arms. The automatic control system ensures the constant pressure of the roller. The bevel roller structure helps to seize materials and crushes the materials in the relative motion to the grinder. The material is ground into powder with the forces of roll and friction. By means of centrifugal force, the ground powder is drawn out to the edge of the grinder. Then the material is mixed with the high speed hot air current and has fully heat exchange so that the water is instantly evaporated. The water in the powder rising with the hot air stream is not more than 1%. The material constantly fed into the mill moves to the rolling track of the grinding roll by the force of centrifugal force in order to replace the drawn out material. Thus, the material can flow in order. The powder rising with the high speed air stream goes into the concentrator, and the qualified powder is centrifuged into the dust collector, the unqualified is ejected out by the rotor blades to collide with the outer still blades and drops into the grinder to get ground again. Then the grinding is repeated.
