This configuration of the Soft starter is used in applications where the driven load has a particularly high inertia else it is difficult to start. For example, in a stir application where the medium is glutinous and stiff at the beginning of the process.
Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silicabearing minerals to form a mixture of calcium a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

The Fostoria MultiMount (UL listed for completely exposed/unprotected outdoor applications) is frequently used for snow and ice melting. They have quartz lamp heaters which are less susceptible to heat loss from wind and they reach high temperatures. The quartz lamps have less mass to hold heat which can be lost to a rise in temperature of the air crossing it.
