THE NEED FOR SAND HEATING

Warm, temperature controlled sand is desirable for all no-bake moulding, and essential when sand reclamation is practiced.

Whenever moulding sand is used at a consistently ideal temperature, catalyst additions can be minimized and subsequently, reproducible setting off & curing times can be ensured. Where sand reclamation is used, consistent sand temperatures can reduce catalysts levels, and particularly Sulphonic catalysts can be minimized. The use of consistent temperature regulated sand can help to reduce atmospheric pollution in the foundry.

ADDITIONAL ADVANTAGES

The Thermaclass sand heater is also a fluid bed sand classifier, which can ensure final elutriation when virgin sand is introduced into the system.

MODULAR CONSTRUCTION

As a result of convenient modular construction, units can be assembled to match customers particular requirements for sand flow and temperature rise.

HEAT CONTROL

The heating elements are installed in thermostatically controlled banks to ensure excellent temperature regulation, regardless of the incoming sand temperature and mixer demand. On summer running the heater will automatically shut down, and the Thermaclass unit will then operate as a fluid bed sand classifier.

RICHARDS CONCEPT

Thermaclass sand heaters are based upon a range of low pressure drop, steel sparge tubes and fluidizing plates. The main fluidizing air is supplied from the single stage fan set (supplied with the unit). A tramp dropout section is also incorporated and the heater can be bypassed whilst this section is cleaned.
