Storage facilities are an essential part of every cement plant. Strudes has been able to meet the highest standards in this market, satisfying various demands of its clients. An installation such as the largest single clinker storage unit in the world, built for Lafarge's Alpena, Michigan Cement plant or the most modern and largest Cement Terminal in North America constructed on Zug Island in Detroit, Michigan, for Lafarge North America confirm very strong position of Strudes on the storage and material handling market.
Another important component of any cement or metallurgical plant is a bulk material terminal. Over many years, Strudes has gained a solid reputation as a reliable partner in the development of such installations. The petroleum market also is served by Strudes.
The most modern and largest Cement Terminal in North America is now being commissioned. This Terminal was constructed on Zug Island in Detroit, Michigan, for Lafarge North America. The Terminal is comprised of eleven compartments, a 46,000-ton capacity silo, ship unloading and rail unloading facilities and a warehouse with packing and palletizing production lines.Three bulk truck loading spouts and scales allow for a simultaneous loading of three trucks in 6 minutes each. The in-line blending system of a few products allows for a modern cementitious material blending and loading on trucks.
The largest single clinker storage unit in the world was built to protect the environment from dust emission and to improve the quality of clinkers. This 400,000 ton capacity storage unit constructed for Lafarge's Alpena Michigan Cement plant can accommodate six football fields. The "A" type storage is: 674 ft long, 311 ft wide and 120 ft high. The clinker is delivered by a pan conveyor and distributed by a tripper conveyor. The reclaim tunnel, constructed beneath the pile, accommodates a belt conveyor which transfers the clinker to a grinding mill.
STRUDES assisted in many other projects at the Exshaw Plant including newhigh efficiency separators, a new homo silo, partition of a cement silo and a complex of cement storage silos.

Cement is mixed with two other materials to have the mix demanded by client. All is done automatically.
Plant improvements include energy saving projects. At Lafarge's Davenport Plant in Iowa, the cement was previously pumped to silos via pneumatic lines at considerable electric power input and complicated, manual valve distribution for each silo. The new system designed by STRUDES includes belt and air gravity conveyors with automatic valve controls. This new system eliminates manual distribution on top of silos and instead is operated from the central control room. STRUDES has designed many other improvements at this plant.

The most modern and largest Cement Terminal in North America currently being commissioned. This Terminal was constructed on Zug Island in Detroit, Michigan, for Lafarge North America. The Terminal comprises an eleven (11) compartment cement silo. OD= 106', H=184', total V=754, 46,000-ton capacity silo, ship unloading and rail unloading facilities and a warehouse with packing and palletizing production lines.
The 60ft water level difference provided a challenge for Strudes’ engineers to design this barge-loading terminal. A floating captive barge equipped with loading equipment was designed.
Lafarge's cement terminal in Pittsburgh, Pa. capitalized on its proximity to the Ohio River, which offered a much more economical means of transportation than the existing rail system. Fluctuation of the water level of the river was overcome with the renovation of a second hand barge whose deck, equipped with pneumatic unloading equipment, rose and fell along with the water level. Incoming barges, loaded with cement, moved along the stationary barge to meet the arm of the unloader. The cement was then conveyed by a piping system to the silos located on the shore. The crane mounted on the deck facilitated the removal of the cement barge's covers as well as the lowering of a small bobcat for final cleaning of the cement barges.
STRUDES engineers assisted Shell in the modernization of their Montreal-East distribution terminal with the addition of a new control system which facilitated the handling of their petroleum products.
