Single-Shaft-Shredder: Range WL 4 - WL 30 |
|
 |
|
|
|
| The all-purpose, reliable shredder! |
|
|
The WL 4 and WL 4 S are the "classical" wood shredders and the WL 10 to 30 models are used for larger quantities of wood waste. WEIMA has the right solution for every type of application and each model can be adapted to the customer’s needs.
All the machines are manufactured in line with the standards of the wood processing industry. The basic model can be modified according to specific requirements (e.g. desired output, hopper shape and rotor types). |

Features |
WL 4 - WL 4S
The all purpose shredder for every type of wood waste |
The WL 4 – WL 4 S series of shred- ders are in operation in thousands of small and medium sized companies worldwide. They are particularly popular because of their extremely robust construction and durability even if they are operated outdoors.
The huge amount of WL shredders installed and in operation worldwide reflects the success of the machines providing a reliable solution to waste reduction at a reasonable price. |
WL 6 - WL 6S
The efficient shredder for large quantities of wood |
The WL 6– WL 6 S series of shredders are used for shredding large volumes of wood waste. The machines are fitted with 800 mm wide rotors.
The WL 6 (and bigger machines) with the 22 kw powered motor are equipped with a hydrodynamic starter clutch so that even when the hopper is full, the smooth running of the rotors is guaranteed. |
WL 10 - WL 30
The reliable shredder for large quantities of industrial wood waste |
| The WL 10– WL 30 series of shredders are used for shredding large volumes of industrial wood waste. The machines are fitted with 1,000 – 3,000 mm wide rotors depending on the model and are powered by a 22 - 90 kw or a double sided motor with 2 x 75 kw. The power of the motor depends on the material to be shredded as well as the number of knives in use and the required output. |
| Further technical features of the WL 4 to WL 30 series |
| The material is fed to the hopper from the hydraulically driven drawer, which regardless of weight or bulk, forces the material onto the turning rotors. The material is then shredded between the rotor knives and the fixed counter knife. The sides of the drawer are so constructed that no material can be fed incorrectly between the hopper and the machine housing. The wood chippings can be extracted by an air suction system, by a screw-transport or a conveyor belt. |
 |
|
 |
| Strong Motor |
|
Protected Hydraulics |
| The machines are powered by electric motors with up to 22kw (WL 4, WL 4 S), 37 kw (WL 6, WL 6 S) and 90 kw (WL 10 - 30). The WL 10- 30 series can also have a double sided-motor with 2 x 75 kw which give the driving force to the rotors through the hydro clutch, V-belt and gear box. |
|
The hydraulics of the drawer are situated inside the body of the machine and are therefore protected from dust and damages. The hydraulic cylinder is cardanically installed so that unwanted shearing force on the piston can be avoided. |
 |
| Quick discharge of materials |
| The shredded material is extracted through the screen which is located under the rotors. The various screen sizes available (10 - 40 mm by WL 4, WL 4 S, WL 6 and WL 6 S; 10 - 100mm by WL 10 -30) determine the size of the end product. |
