篩子根據(jù)他們的結(jié)構(gòu)和運動特點，可分為以下幾種類型：
一、固定篩。包括固定格子篩、固定條篩和懸臂條篩。由于其構(gòu)造簡單，不需要動力，所以在選礦工藝中廣泛用于大塊礦石的篩分。
二、筒形篩。包括圓筒篩、圓錐篩和角錐篩。主要用于建筑工業(yè)篩分和清洗碎砂子、也常用在選礦工藝中作洗礦脫泥用。
三、振動篩。包括機械振動篩和電力振動篩兩種。屬于前者的有慣性振動篩、自定中心振動篩、直線振動篩和共振篩。屬于后者的有點振動篩。根據(jù)篩面運動軌跡不用又可分為圓振動篩和直線振動篩兩種，圓振動篩是由不平衡振動器的回轉(zhuǎn)質(zhì)量產(chǎn)生的激烈振力使篩體產(chǎn)生劇烈的振動作用，篩子的運動軌跡為圓形或接近圓形，由于篩分的效率比較高，目前在選礦廠中應(yīng)用最廣泛。直線振動篩由振動器定向拖動篩子，篩框為水平安裝運動軌跡成直線振動，以保證無聊在篩面上產(chǎn)生劇烈的抖動，主要用于煤的脫水分級、脫介、脫泥，也可用在磁鐵礦的沖洗、脫泥和分級等。
