Cement equipment is installed with safety device

The Cement equipments in our company mainly are: cement ball mill, cement rotary kiln and chinaware ball mill, which are the key equipments of cement production line. Many clients called us to consult that on the base of the existing production capacity, how to further improve the production line efficiency of Portland cement. Now, we are going to give a detail analysis of major factors that affect cement efficiency from the aspects of production facilities, production materials and composition of production line.
Portland cement refers to the hydraulic cementing material made of Portland cement clinker, 0%-5% limestone or granulated blast furnace slag, and moderate gypsum, which is classifies as P.I and P.II
The Portland cement productive technology is representative in the cement production, it use limestone and clay as raw materials, after crushing, dosing and levigating the raw material was fed to cement rotary kiln , calcined into clinker, then levigate into cement by add moderate gypsum( sometimes add some mix material or admixture) .
According to the adjusting device and safety device of feeding end, the medium and fine crusher can be classified as spring cone crusher and hydraulic cone crusher. The working principles of spring cone crusher are consisted of movable cone and fixed cone with manganese steel liner plate. Movable cone mounts on the main shaft 15 by press, one side of main shaft inserts into the bell mouth of excentric sleeve, when the excentric sleeve moves, it can drive the movable cone to cycle. In order to guarantee the cycle movement of movable cone, its bottom surface are sphere and be supported on the spherical bearing. The weight of movable cone and main shaft is bearing by spherical bearing and rack.
Safety device of the machine is the springs installed around the rack, when the material, which should not be crushed such as big iron, falls into the crush chamber, the supporting ring and adjusting ring in the spring are forced to uplift and compress the springs, which can broaden the space between the movable cone and fixed cone, magnify the discharging end, discharge the non crushed material, and avoid the damage to machine. Then under the elasticity of spring, supporting ring and adjusting ring restore to the normal position quickly, and then crush again.
