Main Product Description

Used Lleal Process Model AME-2600-SSF heavy-duty carbon steel double sigma blade mixer, kneader, and extruder designed for intensive batch mixing, homogenization, heated processing, and extrusion of compatible high-viscosity materials, pastes, and industrial compounds. The mixing trough has approximately 2,600 liters (680 gallons) total capacity and 1,300 liters (350 gallons) working capacity, with three carbon steel heating coils designed for thermal oil operation up to 356°F (180°C) and 60 PSI (4 bar). The mixing chamber includes two machined and polished carbon steel double sigma kneading blades with internal water recirculation heating circuits, double-bearing shaft supports, and variable operating speeds from 0 to 25 RPM. An integrated carbon steel extrusion screw with variable 0–25 RPM speed provides material processing and discharge through a heated extrusion chamber. The mixing blades and extrusion screw are powered by a 270 HP hydraulic power pack with independent hydraulic pumps and circuits, hydraulic motors, and planetary gear reducers. Additional features include an insulated dust-tight cover with hydraulic lifting mechanism, rock wool insulation with stainless steel cladding, braided Teflon stuffing box seals, and an air-cooled hydraulic temperature control system. Manufactured by Lleal S.A., Badalona, Spain, this sigma blade kneader extruder is suitable for consideration in processing adhesives, sealants, mastics, polymer compounds, rubber-based formulations, pigment pastes, and other compatible high-viscosity industrial materials.
