BML DD Ball Mill Liquor Direct Drive

The Wiener BML DD sets a new benchmark in grinding by combining proven ball mill technology with an innovative direct drive concept powered by a permanent magnet motor. Designed for highly efficient cocoa liquor grinding, it delivers exceptional process reliability and reduced energy consumption within a compact, space saving layout.

Unlike conventional drive systems, the permanent magnet motor transmits torque directly to the grinding vessel. With no friction, no slip, and no backlash, the system delivers powerful, highly responsive grinding performance, even under heavy load. This ensures stable operation and consistent product quality across a wide range of throughput requirements.

The direct drive architecture significantly increases overall system efficiency by eliminating energy losses from pulleys and belts. The result is lower energy consumption and reduced operating costs over the machine’s lifetime, making the BML DD ideal for producers focused on sustainable, cost efficient operation.

With up to 50% fewer failure prone components, improved material durability, and standardized parts, maintenance effort is substantially reduced. Longer service intervals, simplified maintenance procedures, and lower spare parts requirements minimize downtime and reduce total cost of ownership.

Innovative structural design elements combine performance and efficiency in a compact footprint, featuring a rigid monocoque frame for maximum stability, a reinforced sheath to minimize vibrations and extend service life, and a vertical machine axis with gravity assisted machining and direct drive. This makes the BML DD ideal for space constrained production environments and modular line concepts.

The BML DD is the ideal solution for cocoa processors seeking maximum efficiency, high reliability,  and low maintenance, all delivered in a compact, intelligently engineered grinding system.
