MACHINES THAT DRIVE SUCCESS
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
— now standard on all R-40s, delivering cleaner kernel separation, lower power consumption and reduced maintenance.
Precision fortification using the new VTN vitamin doser ensures accurate, consistent micronutrient dosing.
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.
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**.

The Roff machine is what gives us an edge in the market. It gives us exactly what the customer wants.
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.
proven Roff equipment
The Roff R-40 is a complete maize milling plant. It takes raw maize through eight stages, from intake to packed maize meal. Maize enters by bag feed or from a silo. The C6 grain cleaner pre-cleans it and removes dirt and light material. The conditioning conveyor then adds a measured amount of water to the grain. This moisture toughens the bran so it separates cleanly from the starchy part of the kernel. The DGX degerminator removes the germ and the outer bran layers. The G52 double grader separates the result into samp, grits and germ meal. The MK6 uses a three-stage combination of rollers and sieves to grind and re-mill off-size particles, reducing the graded product to the meal your market buys. The VTN vitamin doser adds micronutrients at a set rate. The Roff conveyor bins hold the finished product for packing. One operator runs the plant, with three to four packers per shift, at 2 to 3 tons per hour.
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.
The C6 Grain Cleaner with aspiration pre-cleans maize and most grains.
The Conditioning Conveyor enables efficient conditioning by adding moisture in a controlled process, resulting in a superior final product.
New DGX degerminator – now standard on all R-40s; cleaner kernel separation, lower power consumption, and reduced maintenance.
The G52 Double Grader separates samp, grits and germ meal for optimal extraction.
Upgraded MK-6 roller mill – for improved sifting precision, easier adjustment, and consistent extraction quality.
Precision fortification using the new VTN vitamin doser ensures accurate, consistent micronutrient dosing.
The Roff Conveyor Bin is used for the packaging and storage of grain or final maize meal products. The unit can be used as a flow control bin or as a packing bin.
Watch a complete Roff R-40 maize mill rise from a bare factory floor in this pre-assembly timelapse. Piece by piece, the structural steel platform goes up, the roller mills, sifters, degerminator and aspiration cyclone are installed, and a full turnkey milling plant comes to life.
This includes the mill, final product bins, electrical panels, installation, commissioning, training, and delivery.
2 to 3 tons per hour
Top Quality Maize Meal
The R-40 Edge Mill is configured to produce top quality maize meal at best-in-class extraction rates.
3 tons per hour
Graded Samp + Maize Meal
The R-40 Samp Mill is configured to achieve a high percentage of samp output while milling the remaining out-of-spec product into maize meal.
3 tons per hour
Brewers Grits or Snack Grits + Maize Meal
The R-40G Grit Mill is a compact and powerful milling system offering dual-function capability, producing both high-quality maize meal as well as grits.
2 to 3 tons per hour
Top Quality Fine Maize Flour
Fine maize flour configuration available with modification to the mill.
The simplicity of the system makes it easy to use and no formal training is required to operate the system. In most cases an operator can be trained in a week on the operation of the essential processes.
Roff offers a turnkey solution that includes the mill, final product bins, panels, electrical installation and commissioning, training and delivery.
Turnaround time is estimated at 3 to 6 months from order. The installation can be completed within 3 weeks.
You have the option to switch between first and second grade maize meal.
The R-40 was designed to allow for quick and easy maintenance and day-to-day running of the mill. The built in maintenance floors and enough space between equipment allows easy access. Scheduled visits are available for regular maintenance by trained and qualified technicians.
If you need a higher capacity mill, have a look at the Roff R-70 or C-80, with capacities of 4 or 5 tons per hour, respectively. Both produce exceptional quality maize meal at Roff’s best-in-class extraction rates. For smaller capacity, consider the SP-1.
