        如何防止振動(dòng)篩在使用中篩網(wǎng)堵塞2016-07-07

        為有效地防止振動(dòng)篩篩網(wǎng)堵塞,應(yīng)針對(duì)上述篩孔堵塞原因采取措施:    

        1、當(dāng)物料粒度較細(xì)、泥質(zhì)含量較多、且篩分粒度較小時(shí),水分對(duì)篩網(wǎng)的堵塞就起決定性的作用。                                       

        2、當(dāng)物料中水分大于5%時(shí),如果沒有條件對(duì)物料進(jìn)行干燥,應(yīng)對(duì)篩面、篩孔作針對(duì)性選擇。          

        3、當(dāng)水分大于8%時(shí),應(yīng)采用濕式篩分。                          

        4、對(duì)片狀顆粒較多的物料,則需要對(duì)物料進(jìn)行破碎改變粒度。                                                                                        

                 合理調(diào)節(jié)篩網(wǎng)張緊力是減少篩網(wǎng)堵孔的一種有效方法,合理的張緊力使篩網(wǎng)同支撐梁產(chǎn)生輕微的二次振動(dòng),從而有效降低堵孔現(xiàn)象的發(fā)生,具體做法是,把張緊鉤做成恒力張緊機(jī)構(gòu),即在張緊螺栓上加裝彈簧。
