A fluid bed dryer is used for drying powders, granules, and other solid materials by fluidizing them with hot air.
Used in pharmaceutical, food processing, and chemical industries
Provides uniform drying and prevents overheating
Can be used for drying materials with different particle sizes and shapes
Resin is a sticky substance derived from plants and used for various purposes such as adhesives, coatings, and in the production of plastics.
Resin is commonly used in the production of adhesives and coatings.
It is also used in the manufacturing of plastics and composite materials.
Resin can be derived from plants such as pine trees or synthesized from petrochemicals.
Examples of resin include epoxy resin, polyurethane re
Resin is measured in kg/liter by calculating the weight of resin in kilograms and dividing it by the volume in liters.
Resin weight in kilograms is divided by the volume in liters to get the measurement in kg/liter.
For example, if you have 5 kg of resin in a container with a volume of 2 liters, the measurement would be 5 kg / 2 liters = 2.5 kg/liter.

I am currently handling centrifugal pumps.
Centrifugal pumps are commonly used in industrial and commercial settings.
They work by converting rotational energy from a motor into kinetic energy to move fluid.
Examples of applications include water treatment, oil and gas production, and chemical processing.
Maintenance tasks include checking for leaks, monitoring vibration levels, and inspecting impellers.
Proper pump selecti...
API 610 and API 685 are the standards for process handling of centrifugal pumps.
API 610 is the standard for general-purpose centrifugal pumps used in the oil, gas, and petrochemical industries.
API 685 is the standard for sealless and magnetically driven centrifugal pumps used in hazardous and toxic applications.
Both standards cover design, materials, testing, and performance requirements for centrifugal pumps.

MSDS stands for Material Safety Data Sheet.
MSDS provides information about the hazards, handling, storage, and emergency procedures related to a particular material.
It is required by law for manufacturers and distributors to provide MSDS for hazardous materials.
MSDS includes information on the chemical composition, physical and chemical properties, and first aid measures.
It is important for workers to read and understa...
LEL stands for Lower Explosive Limit and UEL stands for Upper Explosive Limit.
LEL is the lowest concentration of a flammable substance in the air that can ignite and sustain combustion.
UEL is the highest concentration of a flammable substance in the air that can ignite and sustain combustion.
The range between LEL and UEL is known as the flammable range or explosive range.
Operating within the flammable range can pose si...
