Condition: new, Year of construction: 2026, Consisting of a bale shredder for large round bales, type MHB, and a straw shredder, type MHZ. 1) Bale shredder MHB: Special price from €24,975 net (manufacturing time approx. 15 weeks) Suitable for round or rectangular bales. Includes a frequency inverter (FU) - this regulates the speed of the scraper bed. The bales are placed on the scraper bed and the feed of the shredder is activated. The shredder's tines tear the straw from the bale and fling it into the hopper. Ideally, the combination of a bale shredder and a straw shredder offers the best solution. Technical data, bale shredder: Capacity: 1-2 bales per hour up to a maximum of 600 kg per hour (depending on the sieve size used in the straw mill, kW number of the straw mill). Without a straw mill, the bale shredder can process up to a maximum of 900 kg/h of straw. Maximum size of rectangular bales: 2400x1200x800 mm (L x W x H) Shredder motor: 5.5 kW, 380 Volts Scraper bed feed: 0.75 kW, 380 Volts Dimensions: 3750x1730x2460 mm (L x W x H) Weight: 400 kg 2) Straw shredder MHZ 600 - 11/15 kW; immediately available Special price from €6,995 net Additional cost for the even larger straw shredder (18.5 kW): €2,750 net Technical data, MHZ with special hopper: Motor: 15 kW, 380 Volt electric motor Diameter: 600 mm Hardened cutting blades Sieve with interchangeable inserts Optional (10, 12, 15) 22, 30, 45 mm hole size With star-delta switch, overload protection and 8 m power cord, ready for connection Discharge spout: 160 mm Throwing distance approx. 12 m Dimensions approx. 1600 x 1020 x 1360 mm (L x W x H) Weight approx. 240 kg --- Options at extra cost: Feed auger: + €970 net Cyclone separator (mounting by customer) *should be located a maximum of 10 m away + €2,970 net Simple filter: €1,750 net --- Further options: Industrial extraction system (demonstration unit) + from €9,950 net Optional with rotary valve *makes the material pressure-free + €5,750 net Control system: from €1,620 net Special shredder extension, 3 m *other sizes can be calculated + €9,750 net Briquetting press MPP 180 S; little used demonstration unit 70 mm briquette - up to a maximum of 100 kg/h from €39,700 net * larger machines on request --- Description: The muetek bale shredder has been developed for shredding round and rectangular bales of hay and straw. The shredder attached to the bale shredder shreds straw from all types of cereals, hay, corn and miscanthus. The muetek machines of the MHZ / MHB series are characterized by a robust construction and solid design. The muetek bale shredders of the MHB series are equipped with a chain conveyor, on which the straw bale is placed with a front loader. The support is adjustable depending on the type of bale. The chain conveyor presses the bale against the shredder rotor, and the feed speed is adjustable. The shredder rotor is equipped with several teeth, which tear open the straw bale. The straw separated from the bale is ejected. --- In principle, the machines work for dry source materials: - Straw Cgedpfx Apjb Nulhjhow - Hay --- Shredding hemp only works with a special shredder Additional cost approx. €9,720 net *depending on the design. Shredding hemp does not work with the straw mill. Requirements for the source material: Moisture content max. 12%
