Husmann - Model HL I 1230 - Single-Shaft Wood Crusher Machine

Especially for general, bulky, mixed construction waste, green waste and also wood waste. The feeding material is fed into the hopper, which simultaneously feeds the slowly rotating crushing shaft.

The designation »HL I« is used for the Single-Shaft Crusher. Accordingly, the term »HL II« designates the twin-shaft machines  All crushing machines are offered on a steel profile construction with hook-lift system. Even versions with crawler track, a three-axle trailer chassis or static machines on steel supports are also used.

The Crusher of the HL series was constructed as a pre-crusher for timber, pallet wood, household waste, bulky waste, industrial waste, green waste and roots. Long-term experience with the production of comminution machines at Husmann led to this highly universal and economical crushing machine.

In order to transport the machine, the transport belt can be folded in. The discharge belt is part of the basic equipment as well as the oil tank heating and monitoring devices for the transport belt, oil temperature and oil circuit.

The slow-speed Single-Shaft Crusher of the type HL I stands out for its intelligent hydraulic system with performance control and automatic speed adjustment of 20 up to 35 rpm. The drive unit with Sauer hydraulic pumps and slowly running gear motor achieves a long service life. A torque of of 90.000 – 130.000 Nm, level monitoring, temperature monitoring and overload protection  are further quality features of the crusher!

The switchable und also in automatic mode running comminution process can activate the crushing shaft in both directions of rotation. The feeding material is fed into the hopper, which simultaneously feeds the crushing shaft. Bolted crushing tools guarantee highest throughput even in case of the most difficult feeding material. The hydraulically adjustable side comb with bolted teeth destines the cutting gap to the crushing shaft thereby also the particle size respectively the quality of the feeding material. The bolted crushing tools guarantee a rapid tool change.
