由于普通焊接塑料滤板在使用中周围一圈有死角，在压榨物料时压力较低，因此滤除水分后的物料湿度较大。在国外大型矿业公司都采用了全自动的橡胶隔膜式压滤机，品牌主要有美卓、奥图泰等。

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.
