Drum dryer and cooler - reduced energy consumption

Product catalog summary

Overview: The TK+ drum dryer system is designed for the combined drying and cooling of fine-grained materials, such as sand with a grain size of 0-8 mm, commonly used in dry mortar production. This system offers significant energy savings and operational efficiencies.

Advantages:

Energy savings of up to 20% compared to systems using ambient air for cooling.
Requires a smaller filter unit, reducing investment, operating, and maintenance costs.
Cooling is independent of ambient air, making it suitable for extreme climates.
Can be retrofitted to MOZER double-shell drum dryers delivered since 1985.

System Operation:

Depending on initial moisture, 70-85% of the product is dried in the inner drum using hot gas from fuel combustion.
The remaining product, or "bypassing product," is fed into the outer drum, where it mixes with the dried material.
This mixing results in evaporative cooling, eliminating the need for additional fuel for the bypassing product.

Efficiency and Cost Benefits:

No air is required for cooling, and minimal air is needed for ventilation, allowing for a smaller dust extraction filter.
Compared to systems using ambient air for cooling, the exhaust air volume is halved, further reducing filter size and associated costs.

Retrofitting Capability: The TK+ system can be adapted to existing MOZER double-shell dryers, provided the installation conditions and dust extraction plant are compatible.

Drum dryer and cooler - reduced energy consumption-2

The TK+ drum dryer system is used for combined drying and cooling of fine-grained material, for example sand with grain size 0-8 mm in the usual distribution for dry mortar production. • Energy savings up to 20 % vs. comparable systems which use ambient air only for cooling • A smaller filter unit is required, which leads to a lower investment, operating and maintenance costs. • Cooling is independent of the ambient air; therefore the system is also suitable for countries with extreme hot and/or damp climates. • Can be retrofitted to all MOZER double-shell drum dryers delivered since 1985 and...
