Cement

Most new plants or line expansion projects are seeking techniques to reduce production costs, while minimizing adverse environmental impact during cement production. To meet ever increasing demands, cement kilns must have consistent, reliable feed of raw materials, such as limestone, clay, sand, mill scale/iron ore, and bauxite.

These materials can be prone to arching and ratholing problems during discharge from stockpiles, storage silos, or hoppers. Materials handled at cement plants can cause excessive dusting, wear of equipment, sticking in chutes or conveyors, and result in reduced cement production. Jenike & Johanson provides the following services to cement plants.
