Mobile impact crusher MF 16 S impresses with high throughput in recycling

The Belgian recycling specialist Gyro has put its new mobile impact crusher plant MOBIFOX MF 16 S in Antwerp into operation. With an efficient combination of plants from Kleemann, slag created as a by-product during the recycling of precious metals is processed.

Holistic recycling of precious metals

Gyro has already been working for 15 years together with Umicore at their site for recycling precious metal in Hoboken. 17 different metals are processed in the largest and most complex precious metal recycling plant in the world. As Umicore increased its capacity, Gyro also decided to expand its machinery. Different processes were tested to guarantee a high-quality product. Finally, the mobile impact crusher MOBIFOX MF 16 S from Kleemann was chosen. "With the combination of an MC 125 Z and the MF 16 S, we achieve the best results with high cubicity and a content of fines of 30%", says Guy Kempeneers, Managing Director of Gyro. "At the same time, we have a high hourly output of 350 tons."

The mobile impact crusher MOBIFOX MF 16 S in Hoboken in Belgium processes slag in the second crushing stage for concrete applications.

Efficient processing of slag

The coarse grain sizes of 300 - 900 mm are used as armourstone. The finer material is crushed by the jaw crusher MC 125 Z in the first stage and the grain size of 0 - 125 mm is then loaded directly onto the MF 16 S. Here, the fine material 0 - 4 mm is classified thoroughly by the triple-deck vibrating screen and the oversize grain is crushed to 4 - 28 mm. Both final grain sizes are used instead of gravel and sand for concrete applications. "The specifications for recycling material are becoming more and more stringent. In order to comply with CE and COPRO certification, we take product samples on a regular basis", says Jef Kempeneers. For continuous quality checks of the product, Gyro examines these samples in their own laboratory.

In the first crushing stage, the mobile jaw crusher MOBICAT MC 125 Z crushes the slag.

Plant planning according to customer's wish

The high output of the MF 16 S allows Gyro to produce a higher tonnage in a shorter time and thus save on plant operation costs in the long term. But it is not only the product quality and output that led to the decision to acquire the MF 16 S. Gyro already owns 15 Kleemann crushing and screening plants and places a lot of trust in Kleemann. Together with the Wirtgen Group subsidiary in Belgium and technical development at Kleemann, the machine was designed specially for the recycling application. For this purpose, useful options were also installed in the plant: to keep dust development to a minimum, the MF 16 S is equipped with a spray system. Furthermore, an option is provided for an external power supply to ensure low-consumption operation.
