Electric motor driven, mid-size, low speed chipper, max. log diameter up to 280 mm, meant for industrial chipping for instance producing chips for gasification, with readiness for a re-crusher.

Laimet’s Research and Development division has designed a brand new wood chipper model for terminal use named Laimet LS 280 M IE LW S It works as a screw principle just like the other Laimet’s wood chipper models do. The screw blade is made of very hard metal by the name of Stellite. The screw is very long-lasted in use: when doing normal work its lifetime is about 20.000-30.000 m3. After that the screw must be changed or must be sent back to the factory for overhaul.

Wood chippers made in accordance with the screw principle have many benefits on their side. The first one is that the chipper does not need any feeding device. The rotating screw pulls logs into chipper automatically. In that way the construction of the chipper is very simple and reliable because there is only a one movable screw. The second benefit is that screw chippers produce the chips with very good qualities and homogeneous sizes. The chips are very well-suited for gasification, because the chips sizes are very uniform and the smallest chips are not generated almost at all. That is why Laimet HP-280 LS M S is designed especially on consideration concerning for gasification or heating use, but chips can be used to others purposes too, without screening. In addition to these, Laimet LS 280 M IE LW S chipper is designed into Low Speed model and the benefit is low noise and a more silent run. The terminal chipper Laimet LS 280 M IE LW S can be placed near to population centers without noise or dust problems.

The chipper needs power between 110-200 kW, and chips productivity can be chosen 75-155 m3 an hour by the customer. Electric motor’s power and transmission size depend on chips production volume need. Customer can choose to in-stall three different alternative screws to the chipper, which also make three different lengthened chips. The first one 3/160 makes 20-30 mm, the second one 2/160 makes 35-50 mm and the third screw 1/160 makes 80-115 mm lengthened chips.

Laimet LS 280 M IE LW S unit includes maintenance platforms and a housing of the re-crusher as standard. In addition, a sharpening device with support trails for maintenance of the screw is also included. The basic delivery includes a rotating motor for sharpening rotating of the screw adjusted by frequency control. The chipper has main electric box included all needed electrical devices and a service kit. The service kit includes a lubrication pump for the main bearings and for the bearings of the re-crusher. Besides, there is a manual pump for the opening of the cover of the chipper. The service kit helps maintenance work of the chipper. Laimet LS 280 M IE LW S can be shipped in 20 feet container, but the options and the accessories of the chipper can need more room for shipping.

Terminal chipper Laimet LS 280 M IE LW S is ready for use and it is possible to furnish with standard made accessories like the re-crusher, feed- and discharge conveyors. The re-crusher is chip’s optimizer device, which tears the width of the chips more similar and carries out the chips sizes into more homogeneous. The housing of the re-crusher is integrated in body of the chipper. Accessories such as the re-crusher and the rotation devices.
