32 AGGREGATES MANAGER / February 2018 EQUIPMENT MANAGEMENT and reliability. The ability to select cycle times, cake thickness, feed pressures, and plate styles are what allow fi lter presses to achieve much drier cakes than many competing technologies. Optimizing a fi lter press Like other machines in your operation, the fi lter press should be set up to max- imize your output. You should consider these variables when designing your fi lter press: • Your optimal cake thickness – Thinner cakes dewater faster than thicker ones. • Permeability of solids – The higher the permeability of the material, the easier for the water to pass through, leading to a quicker cycle. • Cake moisture – Know your goal for moisture content and the amount of time needed to achieve it. • Solids concentration in your feed – Less water and higher solids in your feed means faster dewatering. • Opening and closing speed – Finding a happy medium between dewatering cakes and resetting the press can play a big role in the tons per hour capacity of your press. • Test your material – Several char- acteristics can impact dewatering including: - Clay content, - Particle size distribution (very coarse, very fi ne), One advantage of the overhead beam style of filter press is easy access to the plates themselves.
