由于普通焊接塑料濾板在使用中周圍一圈有死角，在壓榨物料時(shí)壓力較低，因此濾除水分后的物料濕度較大。在國外大型礦業(yè)公司都采用了全自動(dòng)的橡膠隔膜式壓濾機(jī)，品牌主要有美卓、奧圖泰等。

Due to the common welding plastic filter plate has a dead corner around the use, the pressure is lower when the material is pressed, so the material humidity after water filtration is higher.

In foreign large mining companies have adopted automatic rubber diaphragm filter press, the main brands are Metso, Outotec and so on.
