Main Grinder.

The second step in the VAN AARSEN RUBBER TECHNOLOGY process is the RTG 800 /1250 main grinder. Main Grinding is an ”ambient” mechanical process and is a grinding and not a cutting treatment. The tyre shreds are crushed between toothed rotor and stator tools. The shreds include the steel wires from the beads, which are of help during the grinding process. The toothed tools are grinding tools, hence they do not necessary need to be sharp. In just this single step the size of the shreds is reduced from (100*150 mm) to a granulate of 0-20 mm of which already 20 % is less then 2,0 mm due to the special design of the machine which is unique in the market. Another benefit of this unique design is that over 96 % of the steel is liberated during this process. The grinding temperature of approx. 80 degrees Celsius is maintained by adding process water in the main grinder. The water added into the man grinder evaporates during the grinding process and is cleaned in a wet-filter to remove the dust before it is released to the environment. The ground rubber with the liberated steel wires is transported via a vibration conveyor. The steel is separated from the rubber by several magnets. The separated clean steel is led via belt conveyors to containers outside the production building. The clean steel without rubber is ready for sales. The ground rubber and fiber mixture is pneumatically transported to the primary screening machine and separated in 3 different grades. In this example we take 0-2 mm, 2-4 mm and 4-20 mm. The fibers in the rubber are separated in the primary sieving machine and pneumatically transported to the central dust aspiration.

Single Rotor Shredder

The first step in the VAN AARSEN RUBBER TECHNOLOGY process is the SRS 1300/1300 S shredder. Shredding is an ambient mechanical process. The whole tyres including the beads are cut into pieces with a size of approximately 100 x 150 mm. In the shredder, water is added as a lubricant as well as for cooling and dust preventive. The used water goes into a settling tank. The clarified water leaves via the overflow into the sewer. What remains is settled street-dirt (sand ,stones, glass). After the shredder the intermediate stock could be situated. This intermediate stock enables you to keep processing when the knives of the shredder have to be replaced. The shreds are fed into the main grinder with the intake dosing hopper with rotating scraper.

Wood Pelleting Pellet Mill

The van Aarsen wood pellet mill C900 is specially developed to operate under the extreme conditions, which occur during the process of wood pelletizing. During the development of the Wood Pellet Mill C900 we have used the experience and knowledge of nearly 6 decades in feed milling. The main advantages of the Van Aarsen C900 Wood Pellet Mill are: Low energy consumption per ton output High lifetime of die and rollers Easy to operate
