Used Chemical & Process Equipment — What We Supply

SIGMA Process Equipment is a specialist dealer in used chemical equipment and second hand process equipment, operating from China's primary concentration of surplus industrial plant. Our stock includes used processing equipment across the core unit operations — separation, drying, evaporation, reaction, heat transfer, size reduction, and material handling — suited to buyers who need proven, inspected machinery faster and at lower cost than new fabrication.

Whether you are looking for a single piece of used process machinery or evaluating equipment for a second hand production line, we can check availability and provide condition documentation within 24 hours of your enquiry.

Used Distillation Columns & Extraction Equipment

We stock used distillation columns for solvent recovery, chemical separation, and refinery duties. Units range from small pilot columns to full-scale packed and tray towers. Solvent recovery distillation column units are frequently in stock in stainless steel and glass-lined construction. We also carry used extraction columns for liquid-liquid extraction processes.

Used Rotary Kilns & Thermal Processing

A used rotary kiln for sale is typically sought for calcination, roasting, drying, or pyrolysis duties. We carry used rotary kilns in carbon steel and refractory-lined configurations. Shell diameter, L/D ratio, drive type, and burner configuration are documented with each unit.

Used Rolling Mills

Used rolling mills — including used hot rolling mills — for metals processing, chemical paste calendering, and rubber compounding are available subject to current stock. Rolling mill second hand units are inspected for roll condition, bearing state, and drive integrity before listing.

Pumps, Filters & Auxiliary Equipment

Supporting process equipment in our stock includes used sparkler filters for clarification duty, used plate and frame filters, and industrial vacuum pumps. Vacuum pump used in pharmaceutical industry configurations — including liquid ring and rotary vane types — are frequently available. We also carry used dairy vacuum pumps for sale for food processing service.

Used Oil Extraction Machines

Our inventory includes used oil extraction machines for solvent extraction and mechanical pressing of oilseeds and natural products. Specify the feedstock and output requirement in your enquiry.

Importing Used Equipment from China

SIGMA handles the full export process: inspection documentation, export packing, customs clearance paperwork, and freight booking. Importing used equipment from China is straightforward when the supplier manages Incoterms, packing lists, and certificate of origin — we handle all of this as standard. Used process equipment dealers who know the Chinese surplus market offer access to brands and models rarely available in European or North American secondary markets.
