Nowadays modern crushing and screening plants regulate material streams within the plant to a large extent automatically. Nevertheless, machine operators still have a strong influence on the final product quality and the daily output. They control the input with their excavators and wheel loaders, i.e. the loading of stone or recycling material. Users also play the main role with regard to output. They coordinate the final products by means of building up stockpiles, intermediate storage areas and loading. With the new Kleemann stackers, Mobibelt MBT 20(i) and MBT 24(i), logistics can now be organised flexibly and adapted to the respective situation.

Both stackers are equipped with a large 1.25m³ feed hopper made of resistant ‘KRS’ (Kleemann Resistant Steel), which permits the feeding of material with an edge length of up to 200mm without any problems. An optional hopper extension up to 2.5m³ is provided with an additional impact bar that prevents the direct impact of the feed material on the conveyor belt and thus reduces wear. Thanks to the hydraulically adjustable feed and discharge height, a fast set-up is possible and the stackers can be used flexibly behind screening and crushing plants with different discharge heights.

The operation of mobile stackers is less complex than crushing plants and it should also be simple and convenient. The Mobibelt MBT 20(i) and MBT 24(i) therefore have an ‘Spective’ operating concept that makes intuitive operation of the machines possible. During a typical workday, the operator receives support with a central operating position, local operation and the option of troubleshooting help via ‘Spective Connect’.
