The Advantages of Roller vs Hammer Mills - Roff Milling

In regions that prefer very fine maize flour, like Angola, Tanzania and Uganda, hammer mills are traditionally considered more cost-effective at producing a fine meal compared to roller mills. Roller mills, in turn, are better known for producing coarser flour. But which is the most profitable in the long run?

 Both hammer and roller mills have their advantages. A combination of both can maximise production capacity and cost-effectiveness, and removing anything from product that went through a hammer mill is very difficult.

 After the degermination stage, a roller mill will prepare your maize meal for final milling by the hammer mill. This process will give you an enhanced product and vastly improve your extraction rate and profitability by balancing the process so that each machine, hammer mill and roller mill, can play to their strengths.

With competitive price and timely delivery, Xingfeng sincerely hope to be your supplier and partner.

Here's how:

 STEP 1: Degermination to increase quality

Germ and bran are removed from the maize kernel during the degermination stage. But because maize kernels are not all the same size, a degerminator will leave a small percentage of bran, even at its optimal setting. Removing this bran is key to improving your maize meal quality.

STEP 2: Roller mills with screens to increase extraction 

In this process the bran is effectively cut away from the endosperm and separated from the maize meal by a combination of rollers and screens, extracting the maximum flour and only passing the product that you want in your end product to the hammer mill.

STEP 3: Large capacity hammer mills

Hammer mills are far better at producing a fine product, as they cannot do any product separation, so effectively what you put in, only comes out when it reaches the desired size. Since the product it receives from the roller mill stage is made up of the same size and type of product, the hammer mill can mill at very large volumes using less electricity, as it’s not working as hard.

northern ILlooking for a faster way to crack corn in the fall than a roller mill. Is anyone using a hammer mill, if so what is it and how many bushels an hour. thanks

Faunsdale, ALWhat are you feeding?

It is hard to make a hammer mill approximate what a roller mill does. Sometimes it doesn't matter, sometimes the hammer mill is more practical. It all depends.

PTO grinder-mixers are pretty common. One can grind a lot in a hurry with a big tractor on the shaft, blend most ingredients adequately and then deliver the finished feed to where it is needed.

There are electric mills as well, some have proportioners to create a blended feed as the grains are ground through the screen. Tend to be quite slow, but can run unattended on a timer or limit switch to fill a bin.

western iowa,by Denisonwe use are haybuster-it can run 100 bu minute-and keeps great-also have a 96 in roller mill-that is for sale-it will do around a hour-we like wetter corn so trying to forget the dry corn-roller mill is better for uprite silos
