We split the flow at degerming, and that single decision shapes everything downstream. A Roller Maize Grinder for Commercial Corn Flour and Grits Production is not a flour mill with a bigger motor; it is a line that has to decide what to do with the germ, the bran and several size fractions at once. Once we separate them, the plant stops producing one product and starts producing a product spectrum with different buyers.
This guide covers the trade-offs we make on that flow: which machines we include at each capacity, why we leave conditioning out of some lines, what the published power and labour figures tell you, and how to write grits sizes into a contract. Our pages list capacities, configurations and named products. They do not publish particle size bands, sifter mesh, roller gaps, extraction rates or flour fineness, and we will mark those gaps rather than fill them.
Whole maize contains a germ that behaves differently from the endosperm under a roller. If it stays in the stream, it affects the meal's colour, keeping behaviour and fat content. If we take it out, we create a separate product with its own value. Our pages describe a degermer on the 10T, 12T, 20T and 100T lines, and a germ stream on the 36T line that can be pressed for oil.
That is why we ask what the plant is built to sell. A mill serving a local ugali market cares about a consistent, fine meal; one with an oil buyer nearby can treat the germ as revenue. The corn flour mill range covers the flour side, while the roller maize grinder sits at the grinding stage. We settle the product list before we discuss a model number.
The 36T description is the clearest statement of the flow we build. It lists cleaning, destoning and metal removal, dehulling, degerming, fine grinding, powder grading, impurity separation and packing, in that order, on a fully automatic line running 24 hours at a stable 36 tons of raw maize per day. That is a train with several outlets, not a single mill feeding one bag.
The 20T is the compact version of the same idea: a multi-function maize cleaner, degermer, conditioning machine, premill, roller mill, elevators and electric control. We publish 900-1000 kg per hour, equal to 20-24 tons per 24 hours, about 65 kW, a small building requirement and one full 20ft container. Our page calls it the best seller and a sensible commercial starting point. The maize mill machine range shows where those tiers sit.
The premill is the step buyers most often want to remove to save money, and we usually advise against it. In our published configurations it appears from the 10T and 12T lines upward, ahead of the roller mill. Breaking the kernel in a controlled first pass makes the roller stage more predictable, and predictability is what lets a line hold several size fractions at once instead of drifting between batches.
Downstream, the 100T description names a first-grade double-sided roller mill, a plansifter and a first-grade degermer, with automatic or semi-automatic packing on a platform structure. We do not publish roller gaps, fluting profiles or sifter mesh sizes. The roller fluting machine is a real item in our single-machine range and belongs in the maintenance conversation, but its settings are agreed against your maize at commissioning, not quoted from a table.
The 36T page names super fine maize flour, standard maize meal, maize grits of different particle sizes, pure maize germ and maize bran from the same line. It also says the line can produce sifted grade one maize meal, roller meal, breakfast meal and maize rice. The 40T description lists sifted grade one maize meal, breakfast meal and maize rice, with packing added to a configuration like the 20T line.
That list is an opportunity and an obligation. Each fraction needs a buyer, a bag or a bin, and a place in the shift plan. We ask which products the buyer will actually sell in year one, then draw the outlets accordingly. We do not publish particle size bands, extraction percentages or grade definitions, so the cuts must be agreed in writing. A line drawn for six products but sold into two markets spends its life handling fractions nobody wants.
The product spectrum we design around | |||
Product | Where it leaves the flow | Published basis | To confirm |
|---|---|---|---|
Super fine maize flour | Fine grinding and grading | Listed on the 36T line | Fineness or mesh |
Standard maize meal | Main meal stream | Listed on the 36T line | Grade definition |
Maize grits | Size-graded fraction | Different particle sizes listed | Exact size bands |
Maize rice | Coarse graded fraction | Listed on 36T and 40T | Size band and yield |
Maize germ | Separated germ outlet | Pure germ, can be pressed for oil | Oil yield and buyer |
Maize bran | Bran outlet | Listed on the 36T line | Local buyer |
The germ is the part of this flow that most changes the business case. Our 36T page states that the separated germ can be pressed for oil and sold separately, and it describes the finished flour as pure white, fine and free of sand and peculiar smell, meeting Ugali and commercial maize flour market standards. Removing the germ helps the meal and creates a second product. We think buyers should count both effects.
We do not publish germ yield, oil content or an oil yield percentage, so we ask for the buyer's own measurement at the trial rather than put a figure in a forecast. We also ask where the germ will be stored and who collects it, because a high-value co-product that sits in a damp corner stops being a co-product. The dehuller and the maize cleaner are listed single machines upstream of that decision.
Our published descriptions of the 10T and 12T lines list a cleaner, degermer, premill, automatic-feed roller mill, automatic feeding auger, electric control and accessories. Neither list includes a conditioning machine or a packing machine. The 20T line does include conditioning, and the 40T and 36T descriptions include packing. We leave those items out of the smaller tiers on purpose, and we would rather explain why than pretend every line is the same.
Conditioning adds a step, a footprint and an operator routine. For a buyer starting with one product and a tight building, that cost may not earn anything yet. The 7T description shows the other end of that logic: a semi-automatic line with pneumatic conveying, a bin divided into A and B sections, a hand slide gate, a cyclone and an air lock feeding the roller mill evenly. We size the flow to the job.
The figures we publish are uneven, and we would rather show that than average them. The 20T line is listed at about 65 kW and one full 20ft container. The 36T line is described as fully automatic, 24 hour continuous, with only two to three workers needed for daily operation. The 100T description names a double-sided roller mill, plansifter and degermer on a platform structure, but publishes no power or footprint figure.
That last gap matters if you are comparing an electricity budget. We ask buyers to put the published figures and the missing ones in separate columns of their own calculation, then request the missing values in the RFQ. The 50T and 60T descriptions offer single-sided or double-sided roller mills with automatic or semi-automatic packing and a platform structure that saves power and floor space. Those are qualitative statements, not numbers we can add to a load schedule.
Three capacity choices, and what each one leaves out | |||
Capacity | Published configuration | Published figures | What we leave out |
|---|---|---|---|
10T / 12T | Cleaner, degermer, premill, roller mill, auger | No conditioning or packing listed | Conditioning and packing |
20T | Cleaner, degermer, conditioning, premill, roller mill, elevators | 900-1000 kg/h, about 65 kW, one 20ft | Nothing in the published list |
36T | Full automatic train with grading and packing | 36 t/day, 2-3 workers | Power not published |
100T | Double-sided roller mill, plansifter, degermer, packing | Platform structure | Power and footprint not published |
Grits are where a specification most often goes missing. Our pages say the 36T line produces maize grits of different particle sizes, but they do not give a single size band or the sieve that defines it. A buyer selling grits to a breakfast cereal or brewer needs those numbers written down with a test method. We ask for the customer's sheet, then agree the sieve set, sample mass and tolerance at commissioning.
The 36T complete line is the configuration we point to when a buyer needs several fractions at once, because it publishes grading and packing as part of the train. Even there, we do not publish extraction rates or yield by fraction. Where a buyer needs a guaranteed split between flour, meal and grits, we agree the test method and sampling point in the order and record the settings that produced the result.
A Roller Maize Grinder for Commercial Corn Flour and Grits Production is a set of choices about what to separate and what to sell. Degerming, premilling, conditioning, grading and packing each change the product list and the building, and the published 20T, 36T and 100T descriptions show how differently we configure them. We have tried to explain why we leave some machines out.
Tehold International supplies grain cleaning, drying, storage, milling and packaging equipment as turnkey packages, and we would rather you send us your product list, your building and the grits sizes your customer buys than accept a single headline capacity. We publish configurations, the 20T power and container figures, and the 36T labour and output. Particle size bands, sifter mesh, roller gaps and extraction rates are not published and must be agreed in the RFQ.
Because our published configuration for those tiers lists a cleaner, degermer, premill, roller mill, feeding auger and electric control, with no conditioning and no packing. Conditioning adds a step, space and an operator routine. For a buyer starting with one product and a tight building, we would rather leave it out. The 20T line does include conditioning.
Yes, on the automatic trains. Our 36T page lists super fine maize flour, standard maize meal, maize grits of different particle sizes, pure maize germ and maize bran from one line, and names sifted grade one maize meal, roller meal, breakfast meal and maize rice as possible products. Each fraction needs an outlet and a buyer, so we ask what you will actually sell.
We do not publish a power figure for the 100T line. Its description names a first-grade double-sided roller mill, a plansifter, a first-grade degermer and automatic or semi-automatic packing on a platform structure. We do publish about 65 kW for the 20T line. For anything we have not published, put the item in the RFQ rather than scale up a smaller figure.
No. Our pages say the 36T line produces maize grits of different particle sizes, but give no size bands, sieve specification or extraction rate. If your customer needs a defined grit, send us their specification. We agree the sieve set, sample mass and tolerance at commissioning and write that method into the order.
That depends on whether you have a buyer. Our 36T page states that separated pure maize germ can be pressed for oil and sold separately, and removing it helps produce a fine, white meal free of sand and peculiar smell. We do not publish germ yield or oil content, so we ask you to measure both at the trial before building a forecast.
