The global surge in electronic waste and used batteries has created an urgent need for efficient recycling technologies. As environmental regulations tighten and raw material costs continue to rise, recycling plant operators are actively seeking equipment that maximizes resource recovery while minimizing environmental impact. Among the critical components in modern recycling facilities, filter press equipment plays an indispensable role in solid-liquid separation processes, particularly in battery recycling and e-waste processing operations.
Understanding Filter Press Equipment in Recycling Applications
Filter press equipment is specifically designed for solid-liquid separation across various industrial applications. In recycling plants, this technology proves especially valuable for handling fine and viscous slurries that result from crushing and separation processes. Whether processing lead paste from used batteries or separating metal powders from circuit board slurry, a well-engineered filter press ensures efficient collection of valuable materials while treating wastewater to meet strict environmental standards.
At San Lan Technologies, our filter press equipment is purpose-built for demanding recycling environments. The system features filter plates measuring 800 by 800 millimeters, with 60 filter plates providing a total filtration area of 60 square meters. Weighing 3,440 kilograms, this robust equipment delivers reliable performance in continuous industrial operations where downtime is costly.
Lead Acid Battery Recycling: A Prime Application
The recycling of used lead acid batteries represents one of the most established and critical applications for filter press technology. The process begins with breaking and separating batteries to recover sulfuric acid, plastic shells, lead grids, and lead paste. The lead paste, typically in slurry form, requires efficient dewatering before it can proceed to the smelting stage. This is where specialized lead acid battery recycling equipment, including industrial filter presses, becomes absolutely essential.
San Lan Technologies offers complete lead acid battery recycling plants with processing capacities ranging from 1 to 10 metric tons per hour. Our integrated systems include advanced breaking and separation units, de-sulfurization equipment that removes sulfur from lead sulfate to reduce melting temperatures and decrease emissions, rotary furnaces for paste reduction with lead recovery rates superior to traditional blast furnaces, and lead refinery kettles capable of producing lead with purity levels reaching 99.999 percent.
San Lan's lead acid battery recycling plants serve operators across 21 countries, with systems designed for continuous operation and maximum metal recovery.
The filter press collects lead paste from slurry with precision, preparing it efficiently for the smelting stage. Meanwhile, our dedicated water treatment plant ensures all effluent from the breaking and separating process meets environmental requirements before discharge. This integrated approach protects both operational efficiency and regulatory compliance.
Integrated E-Waste Recycling Solutions
Beyond battery recycling, filter press technology supports broader electronic waste processing operations. In circuit board recycling equipment lines, wet separation processes generate slurry containing valuable copper powder and trace precious metals. Efficient dewatering ensures maximum recovery of these high-value materials while responsibly managing process water.
San Lan's circuit board recycling plants handle capacities from 300 to 2,000 kilograms per hour, with copper powder purity reaching 96 to 98 percent. Our wet separation systems, including the WCB-2000C model, are designable for capacities up to 5,000 kilograms per hour to meet growing processor demands.
Similarly, cable recycling equipment operations benefit from comprehensive water management and material handling systems. While dry separation methods are common for cable granulation, certain cable types and processing scales require wet processing where solid-liquid separation becomes critical. San Lan's cable recycling machines handle various cable diameters ranging from 1.5 millimeters to 150 millimeters, with scrap cable strippers, compact granulators, and complete plant configurations available.
Expanding Into Lithium Battery and Ore Processing
The rapid growth of electric vehicles and portable electronics has intensified demand for lithium battery recycling capabilities. San Lan's lithium battery recycling plants process 500 to 2,500 kilograms per hour, breaking and separating waste lithium batteries to recover black mass containing nickel, cobalt, and graphite, along with separated plastic, copper, and aluminum fractions.
Complementing our recycling focus, San Lan also provides lithium ore extraction equipment, including crude ore processing plants with capacities from 500 to 5,000 metric tons per day, producing lithium concentrate with grades of 4 to 5 percent. Our tailing ore extraction plants achieve total recovery rates of 75 percent, significantly exceeding the industry average of 65 percent.
