UltraTech Cement Apprenticeship Trainee Interview Questions and Answers

Bearings are machine elements that allow relative motion between two surfaces, reducing friction and supporting loads.

• Bearings are classified into various types such as ball bearings, roller bearings, plain bearings, and fluid bearings.

• Ball bearings use balls to maintain separation between the moving parts, reducing friction.

• Roller bearings use cylindrical rollers to support radial and axial loads.

• Plain bearings have a...read more

Couplings are mechanical devices used to connect two shafts together at their ends for the purpose of transmitting power.

• Couplings are used to transmit power from one shaft to another without misalignment.

• There are various types of couplings such as rigid couplings, flexible couplings, fluid couplings, and magnetic couplings.

• Examples of couplings include gear couplings, grid couplings, jaw couplings, and disc couplings

Cement making involves several processes including crushing, grinding, heating, and mixing raw materials to produce the final product.

• Crushing: Raw materials like limestone, clay, and iron ore are crushed into small pieces.

• Grinding: The crushed materials are then ground into a fine powder.

• Heating: The powdered materials are heated in a kiln at high temperatures to form clinker.

• Mixing: The clinker is mixed with gypsum a...read more

Refrigerators work by removing heat from the interior and expelling it to the exterior.

• Refrigerators use a refrigerant to absorb heat from the interior and release it outside

• The refrigerant is compressed to increase its temperature and then allowed to expand, which cools it down

• The cooled refrigerant absorbs heat from the interior of the refrigerator, lowering its temperature

• The heat absorbed by the refrigerant is then...read more

Air conditioner working depends on various factors such as power supply, thermostat settings, and proper maintenance.

• The air conditioner needs a power supply to function properly.

• The thermostat settings should be adjusted according to the desired temperature.

• Regular maintenance such as cleaning the filters and coils is necessary for optimal performance.

• If the air conditioner is not cooling properly, it could be due to ...read more
