Today, expressions like “efficiency”, “quality”, “integration of processes” are part of our daily job.
We turn our attention to sand cooling: for this reason we have studied the layouts of two classic types of plant (with drum and with cooler).
For both of them we have plotted the average trend of sand temperatures. Temperature must not undergo any great variations from the mixing phase to the moment in which sand returns to the mixer for restoration of its characteristics..

Sand plant (goals)
The modern sand plant must satisfy three fundamental requirements:
•
production of high quality sand;
•
guarantee of constant quality in time;
•
production of a constant high quality at the lowest cost possible.
