The Richards "Verticooler" fluid bed greensand cooler is unique in its approach to greensand cooling. Employing Richards proven fluid bed technology provides for a cooler with no "moving parts" NO Vibration NO paddles.

The unit operates by highly efficient evaporative cooling,

Due to the effective design, minimal maintenance is required.

With a reference of installation world wide the Richards Verticooler has proven to be "Rugged" and "Reliable" in operation.

	Cools sand to 40'C Pre-Mixes Homogenizes Controls Permeability Low Moisture Levels Unit size up to 300 t/hr
·       Employs a unique "fluid bed" technology to cool greensand. The sand is aerated without vibration, moving parts, or paddles. ·       Provides high efficiency evaporative cooling. ·       Controls nominal outlet moisture ·       Requires minimal maintenance. ·       Fits into existing plant layouts due to compact floor space requirements. ·       Integrates water addition relative to tonnage and temperature of return sand. ·       Ensures reliability with proven units operating worldwide up to 300tph.

Additional advantages

• Controlled removal of unwanted fines enables the sand permeability to be maintained.
• The levels of dead clay are kept to acceptable levels thus enhancing the system sand physical properties.
• Consistent low moisture levels allow the sand to flow more easily in the hoppers.
• Less energy, more sand, The high efficiency design allows the use of smaller operating fans using less energy with the resulting reduction in size of the dust collection requirement.

Method of Operation

Efficient patented design utilizes vertical fluidization providing a compact, highly effective system. The hot sand passes vertically downward through a fluidizing element whilst the fluidizing air passes counter flow upwards. Using this technique the cold incoming air makes contact with the coolest out flowing sand to provide the highest possible heat transfer efficiency.
