Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
The convery belt is mainly composed by the expansion cylinder on both ends and the closed belts tightly knotted on them.
Roll crusher is a crushing machine researched and manufactured by our company for coarse crushing.
Chalk is softraw material, it does not require crushing. Marl is alimestonewith admixtures of silex and clay substances, as well as iron oxide.It is a transitional stage to clay. The hardness of marl is lower than the hardness oflimestoneThe more clay substances, the lower its hardness. This is an excellentraw material for cementproduction.See Details ➤

After the clinker is cooled, cement plants grind it and mix it with small amounts of gypsum and limestone. Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects.See Details ➤
