Adani Cement Senior Assistant Engineer Interview Questions, Process, and Tips

The baghouse used is a pulse jet baghouse.

• Pulse jet baghouses are commonly used in industries for air pollution control.

• They use high-pressure air pulses to clean the bags and remove the collected dust.

• Examples of industries using pulse jet baghouses include cement plants, steel mills, and woodworking facilities.

VRM is a vertical roller mill used for grinding raw materials into cement while a ball mill is used for grinding raw materials into fine powder.

• VRM uses pressure and shear generated between the rollers and the rotating table to crush and grind raw materials.

• Ball mill uses impact and attrition between grinding balls and ore particles to crush and grind materials.

• VRM is more energy-efficient and has a higher grinding cap...read more

There are four main components used in making cement.

• Limestone

• Clay

• Silica

• Iron oxide

Blaine is a measure of fineness of cement particles, while residue is the material left on a sieve after cement is passed through it.

• Blaine is a measure of the surface area of cement particles, indicating their fineness.

• Residue is the material left on a sieve after cement is passed through it, indicating the amount of coarse particles in the cement.

• Blaine value is typically expressed in cm²/g, with higher values indica...read more

Role of DP in Vrm and ball mill is to control the differential pressure between the inlet and outlet of the mill to ensure proper operation.

• DP stands for Differential Pressure.

• In VRM (Vertical Roller Mill) and ball mill, DP is used to monitor and control the pressure difference between the inlet and outlet of the mill.

• Maintaining the correct DP is crucial for efficient grinding and preventing blockages in the mill.

• DP c...read more
