The shaking motionshall be imparted to the screen by an eccentric shaft with cam arrangement.该筛机用来检测练焦炉生产的不同尺寸的颗粒，应该采用往复振动设计，大冲程，低速度。采用偏心轴凸轮设计产生振动。The screen decks will be mounted on sturdy steel frame at a convenientheight so that different size fractions any be collected in trays either at thefloor or at the front end of the desk. The machine shall be fitted with sieves of80 mm and 60 mm in upper deck and 40 mm and 25 mm in lower deck. 筛板要安装在坚固的机架上，高度要合适，以便不同尺寸的颗粒可以收集到收料盘里，或者地板上或者工作台的前端。80MM和60MM孔径的筛板装在上层，下两层是40MM和25MM的筛板。Thesieves shall be made of mild steel plates with square punched holes. In theupper deck, the sieves shall be fitted in such a manner that top end shall have60 mm screen and discharge shall have 80 mm screen. In the lower deck theorder of fixing the sieves shall be 25 mm and 40 mm respectively. The sievesshall be fabricate as per IS: 460 ( latest version ) .筛板用低碳钢生产，方形冲孔。上两层筛板装配：顶端60MM的筛板，排料80MM的筛板，下两层筛板装配顺序分别是，25MM和40MM，筛板按照IS:60(最新版本)生产。The perforated plates used in the manufacture of test sieves shall haveuniformly and clearly punched holes.试检筛用的冲孔板上面的孔要光滑一致。The machine shall have provision for adjustment of the angle of inclination ofthe screen and also for adjustment for increasing /decreasing the amplitude ofvibration. The machine shall have feeding skirt to avoid splashing of cokewhile charging on to the screen. It shall have discharging chute. The fractionsas over flow at the screens front end shall be collected in trays suitablymounted on structural frame which shall be bolted with the main framestructure. The overall dimensions of the machine shall not exceed 2500 mmalong the length, 1500 mm along the width and 2000 mm along the height.该筛机应有调整筛板倾角和偏心块，以及增加和减少振幅的规定（条款指示）。应装有进料缘以防止送料的时候物料飞溅，卸料槽。加装收料盘，收料盘架要和主机架固定，以便筛机前端溢出的物料可以收集要收料盘内。机体总尺寸不应超过长2500MM，宽：1500MM，高：2000MM.The machine shall be complete with 4 Nos. of test sieves, 5 Nos. ofcollecting trays, frame for the deck, supporting structure for the motor,starter, V-belts, belt guards, etc.共4台试验筛，5个收料盘，筛板框，电机支架，启动器，V形皮带，护带罩等。Broad parameters of the equipment设备大致参数Type of screen : Shaking (upper),振动（上层）Semi-vibrating (lower)半振动（下层）Screen slope : 6-8 degrees (upper)筛板倾角(层)（6-8度）6-9 degrees (lower)下层（6-9度）Eccentricity of Vibrator : 15mm (upper)振动器偏心率：上层15MM，下层5MM5 mm (lower)Speed of vibration : 330 rpm (upper)振动速度上层：330RPM655 rpm (lower)下层：655RPMCapacity : 900-1200 kg/h产量900-1200公斤每小时。Fractions to be separated : + 80mm, -80 to + 60 mm,处理物料粒度：+ 60 mm to + 40 mm,-40 mm to + 25 mm, -25mmThe broad technical parameters of the screen, furnished above are indicativeonly and shall be checked and confirmed by the contractor.The screen shall be provided with charging hopper, discharging chutes, motorof reputed make, push-button starter, switch fuse unit, V-pulley with beltguard,cover, etc. Appropriate dust extraction arrangement shall also beprov
