WEIMA WL 4 – A tried-and-tested shredder for trade and industry

The V-rotor, developed in-house by WEIMA, is suitable for universal use and is made from solid material. Its aggressive feed mechanism, featuring up to two rows of blades, guarantees high throughput with low power consumption. It can be fitted with hardened steel cutting blades with a blade length of 40 mm. These blades can be turned over several times as they wear, which drastically reduces maintenance costs.

The hopper serves several purposes. Firstly, it is used to feed the material to be shredded into the machine – either manually, mechanically or via a conveyor belt. The generous opening also makes it easy to load very large items. However, what is crucial for shredding is its special design, which is rounded at the front and thus effectively prevents material jams. Even with bulky items, the shredder clears itself automatically. If required, both hopper extensions and lids with gas springs are available.

The ram, which moves horizontally back and forth via a hydraulic system, feeds the material to the rotor. With WEIMA, it can be controlled or cycled fully automatically, depending on the load. It can, of course, also be operated manually if required. For even more aggressive feeding, we recommend additional serrated plates and hold-down devices, which keep even bulky and long parts securely in place. A shock valve fitted to the hydraulic cylinder absorbs any impacts from the drawer, thereby ensuring a longer service life.

Adjust the screen to suit your needs. The smaller the hole diameter, the finer the crushed material that is discharged. Screens can be easily swapped and are bolted in place as standard.

Integrating the sensitive components of a hydraulic system into the machine frame offers many advantages. Not only is the system protected from dust, dirt and other external factors such as the weather, but it also makes the machine even more compact when installed. A separate service access panel ensures easy access for maintenance.

Depending on your requirements and the frame design (raised machine with a conveyor belt opening or side outlet), you have the option of discharging the shredded material via air extraction, a discharge screw or a conventional conveyor belt. With experience gained from many thousands of machines on the market, we are also experts in conveyor technology and can provide you with a turnkey solution from a single source.

Vibration-damping machine feet ensure stability and help to significantly reduce disruptive vibrations in the surrounding area. As the machine does not need to be anchored to the floor, installation is particularly flexible and convenient.

Instead of purchasing standard components, we have been manufacturing our tried-and-tested WAP gearboxes ourselves for many years at our German production facilities. This in-house development ensures maximum robustness even under the most demanding machine conditions. The electromechanical drive, which uses a V-belt and a powerful electric motor, is also optimally protected against impacts and contaminants thanks to a built-in vibration damper. This counteracts increased wear and extends the service life of a machine.

Due to the extreme stresses it is subjected to during crushing operations, a rotor bearing must be built to be particularly robust. To prevent dust or foreign matter from entering the bearing, we have positioned it away from the machine frame. This also makes it very easy to maintain and readily accessible.
