The ultra-high pressure single chamber throughflow filter press adopts a unique formula of high-performance composite materials. The filter plate is resistant to impact, high temperature, high pressure, high toughness, and long service life. The surface has a soft and smooth finish and hardness, which automatically isolates the filter plate and filter cloth, achieving long-term automatic detachment of the filter cake. Good sealing effect, convenient and safe loading and unloading of filter cloth, blowing through the filter cake, without air leakage (the moisture content of non-ferrous concentrate filter cakes such as copper concentrate and gold concentrate is less than 8%, and the moisture content is reduced by 6% -12% under the same working conditions in other industries), the feeding is uniform, and there will be no uneven thickness of the filter cake. Wash thoroughly and thoroughly, saving water by 30% -50%. The blowback pipeline and feed pipeline are clean and free of residual slurry, and the service life of the blowback valve is extended by more than twice.
