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 only condition is that the roof should be at least 7 metres high. Standard industrial concrete floors will suffice; no special flooring is required.

What our clients say

The product that we are getting out of the R-70 is a phenomenal product that speaks for itself. We are competing with products made with European machinery and our customers are still buying our product. The R-70 is a winner in our book – we started off with one, today we own five of these machines.

Evans Killy

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.

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.
