Fabricante de Tubos de PVC Economiza US\$380.000/Ano com Pulverização Interna

Carlos Mendoza, Production Director — Mexico

The ZPM-800 pulverizer has transformed our PVC waste management. We used to sell our pipe scrap for pennies — now we grind it into reusable powder and blend it right back into our extrusion lines. The machine paid for itself in under 12 months.

Contexto do Projeto

A mid-sized PVC pipe manufacturer in Monterrey, Mexico, was generating approximately 350 tons of production scrap annually — including pipe off-cuts, startup waste, and out-of-specification products. They were selling this material to a local recycler at $180/ton, while purchasing virgin PVC compound at $1,050/ton. The logistics of shipping waste off-site also created handling costs and inventory challenges.

Nossa Solução

Zhiyi Machine supplied a complete ZPM-800 PVC pulverizer system including:

  • ZPM-800 turbo-type pulverizer with 75 kW main motor and integrated water cooling
  • 24-bag pulse-jet dust collection system
  • Vibrating screen classifier with interchangeable mesh (20-80 mesh)
  • Automatic screw feeder with load-sensing control
  • Cyclone separator with automatic discharge

Our engineering team provided on-site installation supervision and operator training over a 5-day commissioning period.

Resultados e Impacto

  • Material recovery rate: 90% of input scrap converted to usable PVC powder (20-80 mesh)
  • Annual savings: Approximately $380,000 — replacing 80% of virgin PVC compound purchases with recycled powder at 30-40% blend ratio
  • Payback period: 11 months from installation
  • Waste to landfill: Reduced by 340 tons/year
  • Production quality: Finished pipes meet ASTM D1785 standards with recycled content
