The GHT 4x4 is a filter press with high productivity. The filter plates, which are hung from the upper beam, are moved automatically by a rapid shifting device equipped with a carousel system which reduces the filter press opening and closing sequence to the minimum. Four hydraulic cylinders placed on the plate pack corners ensure perfect operation and limited structural stress, even in the most unfavourable working conditions. Effectively guarded moving parts and the use of state-of-the-art electronic interlock systems mean that the GHT 4x4 conforms to the highest operator health and safety regulations. Routine maintenance operations are simple, thanks to easy access to the filter plates, both for inspection and for filter cloth replacement.
The GHT 2500 is the biggest filter press currently available in the world. This machine is able to dewater huge volumes of slurry reaching very low values of residual moisture thanks to its exceptional chamber volume and filtration area.
Fixed header – 4 cylinders: the fixed header is made of a stainless steel “cellular” structure in order to best resist stress and it supports four (4) hydraulic jacks which are responsible for holding the plate pack closed
Automatic cloth washing system: successful cloth cleaning using a robotic device ensures that optimum filtration rates are maintained.
Protection of the shifting device: The plate shifting mechanism, located inside the upper beam, is effectively protected from sludge, dust and corrosive chemicals by a continuous belt of rubber-lined cloth.
Anti-releasing device: the unique anti-releasing device prevents the simultaneous and premature plate pack release during the filter press opening and it allows a perfect and sequential cake discharge.
Carousel type plate shifting: the carousel plate shifting device assures quick and sequential plate movement by means of an automatic transport system controlled by an inverter.
Laser: a laser control system ensures correct plate pack alignment and stops the filter press in case of any anomaly so that any damage can be avoided.
Mobile hoist: a mobile hoist is provided to reduce downtime in the rare event of plate removal.
Optional open-filtrate-discharge plate pack: this is an alternative solution to the standard closed-filtrate-discharge system. It allows the visual monitoring of the filtrate quality through plates with external drainage ports equipped with cocks. The filtrate discharge from each plate is collected in a launder installed at the side of the plate pack running longitudinally.
