Before continuous slurry processing begins, operators need to verify the hydraulic system, PLC controls, valves, filter cloth movement, pressure settings, safety functions, and the complete filtration sequence. For mining concentrates, tailings, chemical residues, sewage sludge, and other difficult materials, a structured commissioning checklist can help identify problems before they lead to wet cake, cloth damage, leakage, or unexpected downtime.<\/p>\n<p>&nbsp;<\/p>\n<div style=\"text-align: center;\"><img decoding=\"async\" src=\"https:\/\/www.hexinfiltermachine.com\/wp-content\/uploads\/2026\/08\/Automatic-Vertical-Filter-Press-Controls-and-Commissioning-Checklist.jpg\" alt=\"Automatic Vertical Filter Press Controls and Commissioning Checklist\" \/><\/div>\n<h2 id=\"what-should-be-checked-before-starting-an-automatic-vertical-filter-press\"><strong>What Should Be Checked Before Starting an Automatic Vertical Filter Press?<\/strong><\/h2>\n<p>Commissioning should begin with the machine empty. <a style=\"text-decoration: underline;\" href=\"https:\/\/www.hexinfiltermachine.com\/es\/tfp-tower-filter-installation-essential-safety-tips-to-follow-first\/\">Mechanical installation<\/a> and utilities should be confirmed before slurry is introduced.<\/p>\n<h3 id=\"mechanical-installation\"><strong>Mechanical Installation<\/strong><\/h3>\n<p>Check the equipment foundation, structural connections, filter plate alignment, hydraulic cylinders, pipelines, valves, and filter cloth installation.<\/p>\n<p>Key checks include:<\/p>\n<ul>\n<li>Filter plate alignment<\/li>\n<li>Fastener condition<\/li>\n<li>Hydraulic hose connections<\/li>\n<li>Slurry feed piping<\/li>\n<li>Filtrate discharge piping<\/li>\n<li>Filter cloth position and tension<\/li>\n<li>Safety guards<\/li>\n<li>Maintenance access<\/li>\n<\/ul>\n<p>Any visible misalignment should be corrected before pressure filtration starts.<\/p>\n<h3 id=\"utility-conditions\"><strong>Utility Conditions<\/strong><\/h3>\n<p>Power, compressed air, wash water, hydraulic oil, and slurry supply should be available at the conditions required by the selected configuration.<\/p>\n<p>Operators should not treat unstable utilities as machine faults. Insufficient feed supply, low air pressure, or inconsistent water pressure can directly affect cake formation and drying performance.<\/p>\n<h2 id=\"which-plc-and-control-functions-should-be-tested\"><strong>Which PLC and Control Functions Should Be Tested?<\/strong><\/h2>\n<p>Automatic operation depends on different components responding in the correct order. Controls should therefore be tested individually before a complete automatic cycle is attempted.<\/p>\n<h3 id=\"plc-inputs-outputs-and-hmi\"><strong>PLC Inputs, Outputs, and HMI<\/strong><\/h3>\n<p>El <a style=\"text-decoration: underline;\" href=\"https:\/\/www.hexinfiltermachine.com\/es\/producto\/filtro-de-torre-tfp\/\">Filtro de torre TFP<\/a> uses hydraulic control together with PLC, touch-panel control, and automatic valves. Its filtration, pressing, optional washing, drying, cake discharge, and filter-cloth regeneration processes can operate continuously and automatically.<\/p>\n<p>During commissioning, verify signals for:<\/p>\n<ul>\n<li>Feed pump operation<\/li>\n<li>Valve position<\/li>\n<li>Hydraulic pressure<\/li>\n<li>Filter plate status<\/li>\n<li>Cloth movement<\/li>\n<li>Cycle completion<\/li>\n<li>Emergency-stop conditions<\/li>\n<li>Alarm conditions<\/li>\n<\/ul>\n<p>The HMI should also display operating status clearly enough for operators to locate abnormal conditions quickly.<\/p>\n<h3 id=\"automatic-sequence-logic\"><strong>Automatic Sequence Logic<\/strong><\/h3>\n<p>Run the cycle step by step before switching to full automatic mode.<\/p>\n<p>Each stage should begin only when the previous stage has reached its required condition. For example, slurry feeding should not begin before the filtration chamber is properly closed, and cloth movement should not begin before cake drying and plate opening are complete.<\/p>\n<h2 id=\"how-should-the-hydraulic-system-be-commissioned\"><strong>How Should the Hydraulic System Be Commissioned?<\/strong><\/h2>\n<p>The hydraulic system is central to the operation of a tower filter press. Pressure stability, cylinder movement, and leakage should be checked carefully during startup.<\/p>\n<h3 id=\"pressure-and-cylinder-operation\"><strong>Pressure and Cylinder Operation<\/strong><\/h3>\n<p>The TFP uses a tower-type plate structure, horizontal filtration, multiple synchronized cylinders, and self-guided hydraulic cylinders. Hexin states that filtration pressure can reach <strong>20 MPa<\/strong>, depending on the machine and process configuration.<\/p>\n<p>Check hoses, fittings, valves, cylinders, and the hydraulic station for leakage. Pressure should rise smoothly rather than fluctuate sharply.<\/p>\n<p>Multiple cylinders should also move consistently. Uneven movement may affect plate alignment and cloth travel.<\/p>\n<p>&nbsp;<\/p>\n<div style=\"text-align: center;\"><img decoding=\"async\" src=\"https:\/\/www.hexinfiltermachine.com\/wp-content\/uploads\/2026\/08\/Automatic-Vertical-Filter-Press-Controls.jpg\" alt=\"Automatic Vertical Filter Press Controls\" \/><\/div>\n<h2 id=\"how-should-the-filter-cloth-system-be-tested\"><strong>How Should the Filter Cloth System Be Tested?<\/strong><\/h2>\n<p>Filter cloth performance influences filtrate quality, cake formation, discharge, and long-term operating cost.<\/p>\n<h3 id=\"cloth-tracking-and-regeneration\"><strong>Cloth Tracking and Regeneration<\/strong><\/h3>\n<p>Before slurry testing, run the filter cloth through its full travel path.<\/p>\n<p>Confirm that it:<\/p>\n<ul>\n<li>Remains centered<\/li>\n<li>Maintains suitable tension<\/li>\n<li>Does not wrinkle or fold<\/li>\n<li>Moves without contacting structural parts<\/li>\n<li>Discharges cake correctly<\/li>\n<\/ul>\n<p>The TFP operating sequence includes automatic filter-cloth regeneration. The cleaning stage should therefore also be tested before production begins.<\/p>\n<h2 id=\"what-should-be-checked-during-the-first-slurry-cycles\"><strong>What Should Be Checked During the First Slurry Cycles?<\/strong><\/h2>\n<p>Once dry commissioning is complete, slurry can be introduced. Initial cycles should be treated as process trials rather than immediate maximum-capacity production.<\/p>\n<h3 id=\"feed-and-cake-formation\"><strong>Feed and Cake Formation<\/strong><\/h3>\n<p>The TFP working principle begins when slurry enters the closed filtration chamber. Liquid passes through the filter cloth, while solids remain and form the cake. High-pressure water can then act on the diaphragm to further press the cake. Optional washing may follow, and compressed air is used during the final drying stage.<\/p>\n<p>During these first cycles, monitor:<\/p>\n<ul>\n<li>Feed consistency<\/li>\n<li>Filtration time<\/li>\n<li>Pressure development<\/li>\n<li>Cake thickness<\/li>\n<li>Cake moisture<\/li>\n<li>Cake release<\/li>\n<li>Filtrate clarity<\/li>\n<\/ul>\n<p>Hexin specifically positions the TFP for sticky and fine materials and applications requiring relatively low-moisture filter cake. However, actual cake moisture depends on the slurry and operating conditions, so commissioning values should be established with the customer&#8217;s actual material.<\/p>\n<h2 id=\"which-safety-functions-should-be-verified\"><strong>Which Safety Functions Should Be Verified?<\/strong><\/h2>\n<p>Automatic equipment should not be handed over until its protection functions have been tested.<\/p>\n<h3 id=\"interlocks-and-emergency-stops\"><strong>Interlocks and Emergency Stops<\/strong><\/h3>\n<p>Check emergency stops, operating alarms, pressure protection, valve signals, and start-permission logic.<\/p>\n<p>The purpose is to ensure the automatic cycle cannot continue when a critical condition is missing. Operators should also know how to stop the system and move safely from automatic to manual inspection when required.<\/p>\n<h2 id=\"what-data-should-be-recorded-before-final-handover\"><strong>What Data Should Be Recorded Before Final Handover?<\/strong><\/h2>\n<p>A commissioning record creates a baseline for later troubleshooting and process optimization.<\/p>\n<h3 id=\"recommended-operating-record\"><strong>Recommended Operating Record<\/strong><\/h3>\n<p>Record at least:<\/p>\n<ul>\n<li>Feed condition<\/li>\n<li>Filtration pressure<\/li>\n<li>Filtration time<\/li>\n<li>Pressing time<\/li>\n<li>Drying time<\/li>\n<li>Cake condition<\/li>\n<li>Filtrate quality<\/li>\n<li>Hydraulic condition<\/li>\n<li>Cloth tracking<\/li>\n<li>Total cycle time<\/li>\n<li>Alarm test results<\/li>\n<\/ul>\n<p>Changing one important variable at a time makes optimization easier. If several settings are changed simultaneously, it becomes difficult to identify which adjustment improved or reduced performance.<\/p>\n<h2 id=\"why-choose-yantai-hexin-for-vertical-filter-press-equipment\"><strong>Why Choose Yantai Hexin for Vertical Filter Press Equipment?<\/strong><\/h2>\n<p><a style=\"text-decoration: underline;\" href=\"https:\/\/www.hexinfiltermachine.com\/es\/about-us\/\">Yantai Hexin Ambient Protection Equipment Co., Ltd<\/a> specializes in filtration equipment and has worked in the filtration industry for more than 20 years.
