A mill designed for a preparation of malt with production capacity from 3300 to 4000 kg per hour, 11 kW. A professional mill of malt for a preparation of large quantities of beer.
We recommend this model of mill for microbreweries with a volume of the brewhouse to 2000 – 4000 liters.
- Special technical solution for crushing of malt
- The structure of the final product can be changed and the machine meets a wide range of grain malt requirements
- Production of malt with a performance up to 10 tons per hour
WHAT IS THE PURPOSE OF THE MACHINE?
This machine is great for medium sized and small breweries. It usually works in cycles, but we also supply a small technological line with scales , hopper and drill.
We produce three variations of the MM-4000 mill :
- Roller Grinder MM-4000M is designed to a malt grinding.
- Roller Crimper MM-4000G is designed to crush cleaned malt (for mixes and concentrates).
- Roller Crumbler MM-4000P is designed to crush granules (pellets).
Other uses are possible after consultation and approval of the manufacturer.
Prices are all the same (for these three variations).
The machine has been produced since 1995. Its compliance is certified with Czech Republic Act no. 22/1997 Sb. The machine is also certified by the Veterinary Office of the Czech Republic.
TECHNOLOGICAL DESCRIPTION :
The machine is composed of a feed hopper with a sliding inlet and a technological section.
The technological section is made up of welded steel into which the upper working rollers are inserted from above and fastened. One of the rollers runs, the other is driven. It is ensured that the axes of the working rollers remain parallel in all positions. Transfer of torque from the electric engine to the driving roller via V-belt pulleys is done on one side of the case. The driven roller (movable) is driven by gear wheels from the driving roller shaft at the other side of the case. This roller is rotating in the opposite way to the driving roller.
The crimper has a gear ratio 1:1, the grinder and the crumbler have ratio 1:2.

The machine is made of steel – grade 11 (with respect to functionality, endurance and weldability of the parts).
Rollers have special surface protection because their coatings are subject to considerable stress. All standardized parts are made of Czech origin.
The surface is protected by varnish.
The machine is designed to operate in a flammable dust environment with a maximum temperature of + 40 ° C and a minimum temperature of -20 ° C. Therefore, all electrical installations are manufactured with respect to this risk and meet the requirements of EN ISO. The machine also complies with air pollution regulation standards. The machine was designed to operate under mild climatic conditions and has an IP 54 rating.
The noise value done by the machine is 86 dB(A) – crimper and 81 dB(A) – grinder. The noise values were measured at a distance of 1 m from the machine at a height of 1.5 m in place for the attending worker.
RECOMMENDED ACCESSORIES :
The optional accessory for malt mills MM-4000 series for increase the purity of grinding. Its function is the separation of metal parts from milled malt above rollers.
