Roto Grind Straw Mill

Roto Grind is a unique concept delivering improved efficiency on some of the UK’s best farms. Providing a solution to the previously time consuming task of feeding a consistent source of long fibre in dairy and beef rations, Roto Grind will reduce your feeding time and provide a much improved diet to your cattle, resulting in improved animal performance.

[vc_row][vc_column width=”1/1″ animate=”afr”][/vc_column][/vc_row][vc_row][vc_column width=”1/4″][vc_column_text]Roto Grind is the new revolution seen on dairy and beef farms across the UK.

With Roto Grind’s grinding method, very few moving parts are required and the machine has no belt, chain or gear box drives to wear out. Fewer moving parts mean less upkeep, maintenance and running costs.

Roto Grind utilises a unique shear plate system in conjunction with long heavy hammers to produce a simple machine. It does not require screens and uses much less horsepower than conventional grinders. Fineness of grind can be controlled with the shear plates.

Roto Grind can also been used for the following:

  • Pre chopping straw/hay for feeding and mixing in a diet feeder
  • Chopping straw for bedding cows, poultry etc
  • Milling straw for use in biomass boiler systems
  • Milling garden/timber waste for recycling/composting
  • Grain grinding/processing

Compared to other tub grinders on the market:

  • Roto Grind machines are about 1/2 the price of others that come close to the capacity
  • The machines can grind all the wet and tough materials all others cannot.
  • Much lower horsepower requirements means more potential customers (more operators that only have lower horsepower tractors) and much less fuel used.
  • Low maintenance – only 2 moving parts and only 1 wearing part. Hammers now have tungsten carbide hard facing and are reversible all 4 ways.
  • Roto Grind offers more versatile discharge with many options. Allows for grinding into stockpiles, covered sheds, trucks, mixers, self feeders, bale rings, feed bunks, and spreading bedding. The bunk feeder also grinds into a windrow, and the swivel attachment fits all spout designs. In windy conditions, the standard spout design has very little waste compared to a conveyor belt discharge.
  • It’s easier, faster and cheaper to change length of grind.
  • The simple and highly effective governor system allows the same machine to utilise tractors from 70 to 200 horsepower. Operating rpms. can be adjusted from 540 to 1100 rpms.
  • Attachments for grains and specialty grinding are easy to install and operate.
  • Roto Grind does not damage the tractors PTO, drive components and engine because of the design. The fly wheel style rotor and hammers eliminate shock loads.
  • If you ever plug anything, Roto Grind machines can be cleaned out in a few minutes, while screen grinders take much work and hours to unplug.

  • Save 20% to 50% on your hay: in free choice feeding, when stacks or large round bales are set in open area, cattle may waste from 20% to 50% depending on weather and feed conditions. Grinding the roughage and feeding in bunks is less than 1% loss.
  • Up to 40% gains: university research has shown that feeding ground roughage can result in greater weight gains; from 20% to 40% when compared with the same amount of roughage fed unground.
  • Better palatability: cattle are selective feeders and prefer to eat the most palatable portions of feed supply first. Grinding allows the mixing of poor and better quality materials during the actual grinding process. Mixing in this manner means the cattle are more likely to eat all the materials offered.
  • Easier to handle: ground roughage is a more manageable form for conveyor equipment and feed bunks, so less waste occurs during handling and feeding. Also labor requirements are less.
  • Improved quality: poor quality roughage shows increased value when ground, especially when blended with good quality materials.
  • Easier blending: roughage can be directly blended with the other supplements and ingredients in a blender box for a better balanced ration.
  • Healthier animals: a mixture of dry ground roughage with silage provides a much better balanced diet.
  • Grind is better: do your own grinding as needed rather than using commercial grinding in large quantities.
  • Improved milk production: When feeding fresh ground hay to dairy cows, milk production will improve 10% to 15% over feeding unground, free choice hay.

Since using the Roto Grind, our incidents of displaced abomasums have gone from an average of 7 per month to an occasional one. The dry cows are now eating 6kg of straw and we have virtually no feed rejected in the trough. Superb machine, and massive saving on time needed to mix our rations. We don’t need knives in our diet feeder now.

I run a 500 cow dairy farm and was looking for a solution to reduce the time required to process my rations. Processing straw in the rations was taking a considerable length of time and was inconsistent, resulting in a proportion of longer unchopped straw being left in the troughs as refused feed. Having never seen a Roto Grind in action, Enegis gave me a demo of the machine and we spent an hour processing all types of bales, including wheat, barley and rape straw to demonstrate the throughput of the machine and the consistency of the chop length to 2-4” using my own tractor. This straw was then fed through the rations and cow performance monitored for the following weeks. Improved yield on the milkers, and higher intakes of the dry cows ration convinced me to go with a 760 model. We have now been using the Roto Grind for over two years and processes straw for a number of local farms in the area.

With wood shavings becoming increasingly difficult to obtain, we were looking for a solution to our poultry bedding supply. Having recently purchased a dual chop type machine, we found it took a long time to process the straw to a suitable length for bedding the birds. A machine capable of milling the material to a 1.5-2cm length was priority, but this machine would need to be significantly faster than the dual chopper to convince us to upgrade. Having discussed our requirements, Enegis brought us a Roto Grind to trial. Processing time was reduced from 25 minutes to just 3 minutes. Birds were then monitored on the Roto Grind straw for two weeks, then we swapped our previous chopper for a Roto Grind 760.

In conjunction with our nutrition advisor (Hefin Richards of Profeed nutrition), we had been feeding high fibre rations to our cows for many years. We were looking for a method of reducing the time needed to process the rations and deliver more consistency to the diets. Hefin had witnessed first hand the Roto Grind and its benefits on other farms and suggested we look at the unit. We decided to try the Roto Grind for ourselves and have now been using the machine to chop for a number of local farms including the Gold Cup winning Shanael Herd, Evesham. Seeing the benefits of the processed straw in improved cow health and better yields, we think it’s one of the best machines we have invested in.
