摘要
打散分級機是九十年代初問世的新型料餅打散分選設(shè)備，集料餅打散與顆粒分級于一體，與擠壓機配套使用，可以消除擠壓粉碎機邊緣漏料和開停機過程中及正常工作時未被充分擠壓的大顆粒對后續(xù)球磨系統(tǒng)產(chǎn)生不利的影響，以獲得大幅度增產(chǎn)節(jié)能的效果。打散分級機利用離心沖擊破碎原理對物料進行打散，利用慣性及空氣動力學原理對散狀物料實現(xiàn)分級。
為了提高擠壓預(yù)粉磨工藝系統(tǒng)的產(chǎn)量，將更多的粉磨功移至磨外由擠壓打散回路承擔，提高入磨物料的粒度和易磨性，本課題設(shè)計了水泥粉磨系統(tǒng)中擠壓磨后續(xù)設(shè)備打散分級機。整臺打散分級機采用整體緊湊設(shè)計的方法，降低了占據(jù)空間，且提高了打散和分級的效率。根據(jù)打散分級機的工作要求，采用工序高度集中的原則，確定了打散分級機的整體傳動方案，應(yīng)用最優(yōu)化的方法設(shè)置了打散盤及風輪的轉(zhuǎn)速，分析計算了系統(tǒng)的運動和動力參數(shù)確定了傳動比。進行了電動機的選擇、帶輪的設(shè)計、軸的結(jié)構(gòu)設(shè)計、軸的強度校核、鍵連接的選擇計算、滾動軸承的類型代號選擇、軸承的壽命計算、聯(lián)軸器的選擇計算。在此方案的基礎(chǔ)上還進行了改進設(shè)計，將雙傳動拆開，這樣優(yōu)化了軸的設(shè)計，提高了系統(tǒng)的穩(wěn)定性。

Abstract: Scatter grading device is the new blank cake which is published at the beginning of the 90's hits the divergence to choose the equipment, the aggregate cake to scatter with the size grading in a body, with the extruder necessary use, it may eliminate the disadvantageous influence extrusion grinder edge funnel and opens in when the engine off process and the normal work the big pellet which fully extrudes to the following grinding system has not been produced, which obtains the effect of the large scale production increase energy conservation. Scatter grading device carry on using the centrifugal impact crash principle to the material scatters, to disperse the shape realization graduation using the inertia and the aerodynamics principle.
In order to improve the grinding process system extrusion production, will more grinding work moved to the ground by extrusion scattered for loop, improve the grain size and material into the grinding mill sex, the subject of cement griding system design in grinding follow-up equipments scattered extrusion sorting machine. The whole machine by whole grade machine scattered compact design method, reduce the occupy space, and improve the efficiency of the scattered and classification. According to the classification of the machine work requires scattered, the process of the high concentration of principle, determined the classification of the whole machine scattered transmission scheme, the application of optimization methods set the speed of the rotor disc and scattered, calculating the system of sport and dynamic parameters determined the transmission. The choice of the motor, with the design of the shaft, wheel shaft structure design, the intensity, key link choice calculation, rolling bearing type selection, bearing life code calculation, the choice of the coupling calculation. On the basis of this project was the design improvement, will double drive apart, so the design of optimized shaft, improve the stability of the system.
Key words： Roller press; Compressed grinding system; Scatter grading device;
