The maximum angle of a belt conveyor depends on various factors such as the type of belt, material being transported, and the environment.

• The maximum angle of a belt conveyor is typically between 15 to 30 degrees.

• The angle can be increased with the use of cleats or sidewalls on the belt.

• The material being transported also plays a role in determining the maximum angle.

• The environment, such as temperature and humidity, can affect the maximum angle as well.

Hot kiln root clearance should be decreased to prevent damage to the kiln.

• Hot kiln root clearance refers to the distance between the kiln shell and the supporting rollers.

• If the clearance is too large, it can cause the kiln to sag and damage the rollers.

• Decreasing the clearance can prevent this damage and improve kiln performance.

• Regular maintenance and monitoring of the clearance is important to ensure safe and efficient operation.

Root clearance is the distance between the gear teeth and the mating gear's root circle.

• It is an important parameter in gear design and manufacturing.

• It ensures proper functioning of gears and prevents interference.

• It is measured by placing a thickness gauge between the gear teeth and the mating gear's root circle.

• The clearance value depends on the gear type, size, and application.

• For example, the root clearance for spur gears is typically 0.25-0.33 times the module.

• In helica...read more

Power factor is the ratio of real power to apparent power in an AC circuit.

• It is a measure of how efficiently electrical power is being used.

• A power factor of 1 means all the power is being used effectively.

• A power factor less than 1 means some power is being wasted.

• Capacitors and inductors can be used to improve power factor.

• Power factor is important for energy efficiency and cost savings.

DRI sponge iron is a type of iron produced from direct reduction of iron ore using natural gas or coal as a reducing agent.

• DRI stands for Direct Reduced Iron

• Produced by reducing iron ore in the form of lumps, pellets, or fines

• Commonly used in steelmaking processes as a substitute for scrap iron

The pressure and temperature of the boiler are crucial factors in maintaining its efficiency and safety.

• Pressure should be monitored regularly to ensure it stays within safe limits.

• Temperature control is important to prevent overheating and potential damage to the boiler.

• Proper maintenance and regular checks are necessary to ensure the boiler operates at optimal pressure and temperature levels.
