Technical Parameters of laboratory top bump screen

一、用途

該機(jī)廣泛適用于輕重工業(yè)、地質(zhì)冶金、化工建材、煤炭礦山、砂輪陶瓷、醫(yī)藥科研等行業(yè)的化驗(yàn)室，試驗(yàn)室是對(duì)物料顆粒分級(jí)篩選的理想設(shè)備。其優(yōu)點(diǎn)：具有精度高、速度快、節(jié)省人力、低噪聲等物點(diǎn)。尤其對(duì)建筑業(yè)砂石骨料試驗(yàn)更為理想，可將15kg骨料分二次裝料，每次開(kāi)機(jī)五分鐘，既方便以簡(jiǎn)單完成分級(jí)工作。

I. Application 

The machine is widely applied in laboratories for light,heavy， Geological,metallurgical,chemical,building material ,coal, mine, grinding wheel ceramic and pharmaceutical industries and research institutes and is an ideal apparatus for particle size classification and screening of materials in laboratory. It features high accuracy ,rapid speed, less manpower,low noise and others.It is also ideal to be employed  in  test  of sandstone aggregates in construction industry.15 kg aggregate can be loaded two times with each  to run for 5 minutes and can be classified successfully with easiness and simplicity .

二、技術(shù)參數(shù)

三、工作原理

該機(jī)主要有傳動(dòng)、擺動(dòng)、振擊、夾緊機(jī)構(gòu)及電器等部件所組成。本機(jī)由動(dòng)機(jī)通過(guò)主軸，（傳動(dòng)軸）帶動(dòng)齒輪，有蝸輪再帶動(dòng)凸輪，主偏心軸帶動(dòng)兩個(gè)付偏心軸，從而使篩座具有回轉(zhuǎn)及振擊雙重動(dòng)運(yùn)動(dòng)。

III.Working principle

The machine is mainly composed of driving, oscillation, vibration and strik, clamping mechanism and electrical components. It is operated with motor to drive gear , worm wheel to drive cam and main eccentric shaft eccentric shaft to drive two auxiliary eccentric shafts through main shaft ,thereby allowing strainer seat to make dual movements of gyration and vibration and strike.
