Trough chain conveyor.The distribution and collection conveyor.

The Standard Line is the ideal solution for numerous applications at grain collection points, in raw goods reception, malting plants, breweries etc. Despite its compact size, the conveyor achieves high transport capacity due to its premium-quality plate link chain, while also providing gentle handling of granular and floury bulk goods.

The Sanitation Line is designed to meet the strict hygiene require-ments in processing plants such as grain and animal feed mills. Bühler has equipped this special trough chain conveyor model with a self-cleaning return end and round link chain allowing it to comply completely with even the most stringent hygiene guidelines. Additio-nally, the automatic chain tensioning system guarantees operational reliability and shorter maintenance times.

Drop-forged chain links make the Heavy-duty Line extraordinarily rugged. A high loading capacity in combination with low wear and a sturdy design are just some of the features that guarantee the quality of this system.

Trough chain conveyor. Specialized versions.

Distribution and clearing conveyor for free-flowing products in flat storage applications.Bühler‘s distribution and clearing conveyors enable uniform filling and discharge of flat storage compartments of any desired height. Rugged components such as travelling gear with friction wheel ensure disturbance-free system operation. In combination with sta-tionary or movable belt conveyors, distribution and clearing convey-ors make complex logistics systems possible.

In addition to the standard versions of the trough chain conveyor, Bühler offers numerous specialized models for other bulk goods that can be employed in many different areas of production.

Incline LineA combined horizontal and vertical conveyor.

Incline Line – horizontal and vertical conveying in a single system.Combined horizontal and vertical conveying is the key function offered by this chain conveyor. Specially shaped chain flights across the entire cross-section of the trough allow for form-fit transport. In particular, the conveyance of sticky materials or transport between critical process steps during which the process itself cannot be interrupted (e.g. oil mills) are typical applications for the Incline Line. This chain conveyor is suitable for throughputs up to 480 t/h (wheat).


Elevators.Convenient solutions for vertical conveying.

The Standard Line, with its comprehensive package of optional equipment, is capable of handling the majority of applications in silo and storage facilities. A split hood, inspection and cleaning ports on the boot and casings, and cleanout slides ensure easy cleaning and maintenance.

The inclusion of a round boot to minimize product residues in the conveying system, as well as the dust-tight design of the Sanitation Line, fulfill the strict hygiene requirements in processing plants such as flour mills.

The rugged design of the machine parts and the use of wear-resis-tant materials guarantee the long service life and high dependability of the Heavy-duty Line. These features make the Heavy-duty Line particularly suitable for high capacities and heights.

For procedural reasons, the elevation of products is imperative in nearly all silo facilities and processing plants. Thanks to their low energy consumption, eleva-tors supplied by Bühler are extremely economical in operation and are ideally suited for the vertical transport of bulk goods.

Belt conveyors.Going the distance – gently.

The trough belt conveyor was specially developed for short dis-tances and lower capacities. Completely pre-assembled segments and lightweight construction allow for a particularly cost-effective investment.

Transporting large quantities of product over long distances presents a signifi-cant challenge to conveying systems. With belt conveyors from Bühler, such tasks can be handled reliably, gently and economically.
