The Next-Generation R-40: What’s Changed

  • Simplified process flow

    Fewer moving parts, less maintenance, faster installation and lower running costs.

    — achieved through an optimised layout that uses more gravity conveying and fewer mechanical parts, reducing space requirements, energy use and maintenance.

    Compared to previous model

  • New DGX Degerminator

    — now standard on all R-40s, delivering cleaner kernel separation, lower power consumption and reduced maintenance.

  • New VTN Vitamin doser

    Precision fortification using the new VTN vitamin doser ensures accurate, consistent micronutrient dosing.

CLASS-LEADING EXTRACTION RATES

R‑40 maize mill

Roff brings you the R-40 Maize Mill range, boasting the same best-in-class extraction rates delivered by the R-70 and C-80 Mills. We’ve designed the R-40 for the entrepreneur who needs a streamlined, profitable and reliable mill based on proven technology with the flexibility to never miss a new market opportunity. Think compact, efficient design housed in multi-story frames featuring dust extraction and an offal collection line, and a milling capacity that will enable you to achieve success.

Extraction rates

The R-40 Maize Milling Plant is built using proven equipment (MK-6 platform), guaranteeing exceptional performance. It achieves an extraction rate* of about 69 to 74% (Super/Grade 1), or 80 to 85% for special maize meal (refined) – allowing you to produce and/or export both these products with ease**.

Save on civil costs and turnaround time with the R-40

The R-40 mill range has a small footprint between 93m² and 137m². It comes with a support structure, so no special structure or building is required. The only condition is that the roof should be at least 7 metres high. Standard industrial concrete floors will suffice; no special flooring is required.

We chose a company close enough to us so that we could do research and development work together. We recognise Roff as a strategic partner that supplies the high quality equipment, support and R&D work whenever we want to do something new. It’s a successful partnership in our opinion.

Awie Griesel

I bought the Roff R-70 Mill because of Roff’s trusted reputation in the industry. When you buy a mill, you can import one which is risky, so I decided to rather choose a local company with the view of building a longstanding relationship with them.
