The Cormall Multimix MTX reduces labour costs, tractor usage and size of feed passages and thereby increases efficiency and the number of cows housed. Cormall have developed control systems and manufacturing techniques so that the mixer can be used to feed fully automatically.

Mixing Principle

All the feed ingredients are loaded into the lower end of the mixer where it is transported to the top of the mixer by the two augers. Here opposite mounted auger blades combined push the material upwards into what can be described as a molehill, where it naturally falls naturally backwards.

The mixing of the various ingredients is carried out both by the augers during transport upwards as well as in the molehill. Smaller quantities of the diet should be added first followed by the larger components to ensure that vitamins and minerals are equally mixed in the mixture and to produce a completely homogeneous mix.

The transmission mixer is placed at the top in such a way to allow the top of the auger to travel up and down 50 mm to prevent stones being crushed. When using straw in the mixer, this also prevents the straw being compressed between the machine and the auger to ensure a homogeneous mix.

Experience has shown that machines last longer when all of the main hopper is produced with thicker 10 mm plating and not just in the area were the augers work. Furthermore the auger size is 15 mm. Combined with the very low energy usage needed for the mixing operation, the Multimix MTX has a long lasting life span as well as being energy efficient.

FARMERS GUARDIAN ARTICLE

The following article appeared in the Farmers Guardian on Friday 19th April 2013 in the Livestock section:-

Auto-feed system boosts milk from forage.

Feeding little and often is key to savings

An increase in milk from forage and a significant reduction in wastage are two of the benefits of an auto-feed system installed on Tim Gibson's Hunters Hill farm, near Bedale, North Yorkshire.

Mr gibson told delegates at a meeting at his farm last Thursday (April 11th 2013) that milk from forage had been negligible before he set up the auto-feeder in December 2011.

The milk from forage figure is currently 1,000 litres/cow, which represents a welcome cost saving on his 180-cow herd. He is also pleased the cows have achieved a 'moderate' yield increase, given the challenging weather conditions. He has also observed a one point increase in the average condition score.

"I believe feeding little and often is the main reason for the improvement in milk from forage," said Mr Gibson, who is also a pioneer of robotic milking machines. He previously used a self-feed sialge system, with blocks placed in the passageway.

"Fresh food is added regularly through the auto-feeder, so cows do not have to pick through the ration. I would estimate only about 5kg/day goes to waste, with this mostly made up of stones and other debris which come in via the silage."

Maintenance

The principle of auto-feeding dates back to the 1960s, but the technique failed to gain popularity at the time, largely due to mechanical breakdowns and maintenance problems, he explained.

"Today's version takes advantage of modern technology. Our system is fitted with sensors which stop the machine if it encounters resistance. It will telephone or text us if a breakdown occurs.

"The quality of available steel has also improved over time and I have used a steel liner for the base of the troughs. This feature was added as I understand it is better for cows to feed off a smooth surface. Steel also offers less resistance to the chain and creates a more hostile environment for mould, compared with concrete."

Auto-feeder

  • 1.5m (5ft) trough span
  • estimated total cost for 180-cow herd (includes feed bunker) - £70,000 - £90,000
  • The Danish firm Cormall supplies the feed bunker. It is fitted with weigh cells and can handle both liquid and solid feedstuffs, with knives available as an opyional extra. It uses a diagonal twin-auger to move material
  • The active chain can be set to a range of timescales. Mr Gibson normally feeds every two hours
  • The chain conveyor can move between two separate buildings

Cormall Dairy

The Cormall Dairy is a complete mixing and feed delivery system for housed stock. Three systems are available to suit different unit sizes and layouts.

Chain Conveyer and Feed Table

This system was developed in the early 1960's and originally used for manure handling. It is simple and easy to install. The chain conveyer system is the only active one that is self-cleaning. For automatic feeding the Cormall Dairy system is economical and can also work with smaller manger widths. It can also be used for group feeding of stock.

This system was developed in the 1960's and has been sold since. It is mostly used on big farms from 500 to 1500 cows. The rubber belt conveyer is a very reliable system. It keeps the manger area free for driving and working with other machinery. It can work with longer mangers and can also be used for group feeding.

The Railwagon system was also developed in the 1960's and was originally only used for distributing beet. It is a flexible system that keeps the manger area free for driving and working with other machinery. It is very suitable for farm sizes up to 450 cows, and a good system for group feeding.
