I applied via Newspaper Ad and was interviewed in Dec 2022. There were 2 interview rounds.
Chemical consumption per ton of coal varies depending on the process and type of coal.
The chemical consumption can range from 0.5 to 10 kg per ton of coal.
The type of coal and the process used can affect the chemical consumption.
Common chemicals used include lime, caustic soda, and sulfuric acid.
Chemical consumption is typically higher in processes that involve coal washing or desulfurization.
Regular monitoring and opt...
The amount of magnetite powder used per ton varies depending on the specific process and application.
The amount of magnetite powder used per ton can range from 100 to 1000 kilograms
The specific process and application will determine the amount of magnetite powder needed
For example, in the production of iron ore pellets, approximately 200 kilograms of magnetite powder is used per ton
Pressure in heavy media pump is crucial for efficient operation.
Heavy media pumps require high pressure to move dense fluids like slurries and suspensions.
Pressure is created by the pump's impeller, which forces the fluid through the system.
The pressure must be carefully monitored and controlled to prevent damage to the pump and ensure optimal performance.
Factors that can affect pressure include the viscosity and densi...
The capacity of the washery depends on the capacity of the rotary breaker.
The capacity of the washery should be equal to or greater than the capacity of the rotary breaker.
The rotary breaker breaks the coal into smaller sizes, which are then processed in the washery.
The capacity of the rotary breaker can range from 100 to 2000 tons per hour depending on the size of the coal and the requirements of the customer.
Coal and ash should be matched to ensure efficient combustion and minimize environmental impact.
Matching coal with ash involves analyzing the chemical composition of both to determine the appropriate ratio for efficient combustion.
The ash content of coal can affect its heating value and combustion efficiency.
Matching coal with ash can also help minimize environmental impact by reducing emissions of pollutants such as s...
Quality control of coal involves various tests and measures to ensure its purity and efficiency.
Coal samples are collected and analyzed for their chemical composition, moisture content, and ash content.
Various tests are conducted to determine the calorific value of coal, which is a measure of its energy content.
Coal is also tested for its sulfur content, which can have environmental implications.
Quality control measure...
Drop in pressure in pump can be caused by various factors.
Leakage in the pump or pipeline
Clogged suction or discharge lines
Air pockets in the pump or pipeline
Worn out impeller or casing
Incorrectly sized pump or motor
Low fluid level in the pump
High fluid viscosity
Excessive friction losses in the pipeline
The water circuit layout in a washery is designed to efficiently recycle and reuse water for various processes.
The layout includes a series of settling ponds and tanks to remove impurities from the water.
Water is then treated with chemicals to remove any remaining impurities.
The treated water is then reused in various processes such as coal washing and dust suppression.
Effluent water is discharged after meeting the req...
The amount of ash produced in a rotary breaker process depends on various factors.
The type and quality of coal being processed
The size and capacity of the rotary breaker
The speed and angle of the rotary breaker
The moisture content of the coal
The efficiency of the dust collection system
Typically, the ash content in coal ranges from 5-40%, so the amount of ash produced will vary accordingly
