AGGREGATES MANAGER / February 2018 35 conveying system, - Gravity flow of filtrate water away from the filter press, - Clearances required for replacing components, - Ability to deliver components/material to the filter press, and - Lift capabilities designed to meet the specific tasks. Walkways, railings, harness tie-offs, and access platforms are important design considerations incorporated to optimize safe operation and maintenance activities. Designers who are working with typical polypropylene filter plates and standard cloth media should consider roof and side enclosures to prevent harmful damage caused by prolonged exposure to the sun's UV radiation. Ultimately, regardless of the filter press type and size, close cooperation with the end user, facility engineer, and OEM will achieve a properly designed facility that facilitates good, safe maintenance practices. Maintenance requirements Like any piece of equipment in your operation, filter presses require maintenance. When maintenance and inspection checks are performed regularly, a filter press can work at its best. Maintenance and inspection tasks to the filter cloth, plate, hangers, power unit, and opening mechanism are all important. Consider these items when inspecting your filter press. Filter cloth: • Should be checked for tears and rips at least once per shift; • Should be checked for cleanliness at least once per week and washed as needed, ensuring material does not build up between filter plate and filter cloth; and • An automatic wash system can be installed on applications that require frequent washing. Filter plates: • Should be checked weekly or if filter cloths tear or rip for wear; • Can be repaired if damage is in a small shallow area; and • Can be replaced through the bottom, top, or side depending on the type and configuration of the filter press. Filter plate hangers and wheels: • Should be checked weekly for operat- ing alignment and wear; and • Bolts should be checked periodically and tightened as needed. Filter plate opening mechanism/chain: • Chain drive and tail shaft bearings should be lubricated per the recom- mended schedule; and • Chain should be checked weekly for proper tension. Hydraulic power unit: • Change filters at least every 500 hours of operation or after every oil change; • Perform oil testing every six months and change as recommended by hydraulic oil supplier; and • Check calibration of pressure indica- tors and relief valves annually. Lubrication: • Lubricate bearings and change oil per the OEM-recommended lube schedule. Feed pump: • Check gland water condition, level, flow, and pressure every shift; • Check lubrication of bearings weekly; and • Perform condition monitoring of pump weekly. Producers who take into consideration the right sizing and location, as well as perform the proper maintenance are most likely to enjoy optimal results from their filter press.
