2. Foundation Building: It forms the base of the silo and provides substantial support to the silo for weight and stability. Generally, concrete and steel, which depend on the size and weight of the silo, are used for its construction. 3. Silo Erection: After the foundation is built, on-site assembly of the silo sections will be done.

3. Raw material grinding: The crushed raw materials are ground into a fine powder, called raw meal, using grinding equipment like ball mills or vertical roller mills. 4. Pyroprocessing: The raw meal is heated in a rotary kiln at high temperatures (around 1450°C) to form clinker, a semi-finished product consisting of small, nodular lumps. 5.

Forage blown into the center of the silo is uniformly distributed and compacted by the 16-inch auger. During unloading operations, the auger cuts and sweeps away from the silo wall, where feed flows freely onto the double chain conveyor below. Very high rates of both, loading and unloading, makes your forage operations much more efficient.

In a ball mill, the grinding process takes place by impact and attrition. On the other hand, a vertical roller mill exposes a bed of material to a pressure high enough to fracture the individual particles in the bed. This process creates a stable and consistent grinding bed between the rollers and the VRM table.
