- Model LR1000/1400 - Reliable Wood Shredder

From

0

The LR1000/1400 is fully adaptable to your application situation and is suitable for businesses with a wood waste volume of 12m³ per week. Thanks to its size the shredder is ideal for pallets and bulky wooden pieces. The strong throughput capacity of the LR1000/1400 is a result of the powerful motors and the performance-oriented machine configuration. The configuration with a long rotor, a large perforated screen surface and an optimised cutting unit design gives you the capacity you need in your operation. High performance requires reliable machine operation which we ensure with a full range of high-quality technological components.

Thanks to the rotor's special mounting, dust-protected bearings, a proven transmission damper and special cutting tools, the wood shredder is also very low maintenance and has a long service life. In the event that foreign objects are pulled into the shredder, the smart drive control automatically shuts down the motor. In addition, the shredder has been equipped with an automatic reverse to prevent motor overload.

Energy-efficient technology is particularly important for machines that run continuously. For this reason, the LR1000/1400 uses cutting tools with a specific blade design that shred using very little energy. In addition, the motor shuts down automatically if no material is fed into the machine for more than 3 minutes. This saves energy and lowers your operating costs at the same time.

The LR1000/1400 produces a high quality granulate for immediate use in wood chip heating systems or briquett-generation using peripheral systems that can be connected if needed such as metal separators or pipe magnets that we can customise to your needs.
