4. Working Principle Of Rotary Kiln Under High Temperature?

The rotary kiln in the application area, the numbers to be most cement industry. The whole process of cement production line summarized as ‘two ground a burn,’ with ‘a burning,’ is made by grinding good raw material, in the high temperature of kiln under the action of the process of burning become clinker. The equipment is also widely used in metallurgical, chemical, building, refractory material, environmental protection, and other industries.
The rotary kiln under high temperature overloaded alternating slow operation, and its annex equipment maintenance and thermal rail system related to the level of control of the rotary kiln working safety and efficiency. Therefore, rotary kiln cement produces the host, commonly known as the cement factory ‘heart’.Rotary kiln cement industry forged in the main equipment burn the cement clinker. The stand or fall of sealing device directly affects the thermal rail system and run the rotary kiln capital. Strengthen rotary kiln daily maintenance data analysis of the pack; be helpful for equipment management work.
Cement kiln is used for making of cement clinker and there are dry and wet methods to make cement. Metallurgy chemical kiln is used in metallurgy industry and ironworks for lean iron ore, chromium ore and ferronickel ore calcimine. Rotary kiln is used for calcimine of high aluminum vandal ochre in refractory material industry; for calcimine of calotte and aluminum hydroxide in aluminum manufacturer; for claiming of chrome sand ore and chrome powder ore in chemical plant.Lime kiln is used for baking active lime and dolomite in the steel factory and ferroalloy factory.
Rotary kiln is the main equipment for calcining cement clinker and it can be used widely for cement industry ,metallurgy industry ,chemical industry , etc.Which can be divided into cement kiln ,metallurgy chemical kiln and lime kiln according to different materials.

6. What Is The Difference Between Fuse And Circuit Breaker?

A fuse has a wire that melts with the heat of a short circuit or high current and interrupts the circuit. Once melted, you have to replace it.
Circuit Breaker:
A circuit breaker interrupts the current without melting ( a pair of metal sheets with different thermal expansion coefficient, for example) and can be reset.

9. What Does “14-2” Mean?

This is used to describe the size and quantity of conductors in a cable. The first number specifies the gauge. The second the number of current carrying conductors in the wire – but remember there’s usually an extra ground wire. “14-2” means 14 gauge, two insulated current carrying wires, plus bare ground.
2 wire usually has a black, white and bare ground wire. Sometimes the white is red instead for 220V circuits without neutral. In the latter case, the sheath is usually red too.
3 wire usually has a black, red, white and bare ground wire. Usually carrying 220V with neutral.

10. Mention 7 steps involved in continuous service improvement.
