adhesive feeding system consisted of the gear pump, membrane pump and liquid detector so the measurement is accurate, the mixing period is short and the loss of first and last round sand is less. the doublearm of machine rotates flexibly and the available working area is large. the open type sand mixing stir cage is advantage for cleaning or adjustingthe blade. the dust collection and deflavour system are combined in the primary and secondary connection aswell as the secondary outlet, in order to reduce the content of powder and binder air in the sand. the electric control system is plc controlled and completely restricting protection. the information displayed by mimic board with reliable operation. 7. sand temperature regulator the main principle of sand temperature regulator: the sand is conveyed to sand temperature regulator from the top of sand temperature regulator and there are water pipes in the sand temperature regulator. the cooling water or hot water continuously flow in the heat sink which assembled with multilevel cooling pipes. hot sand or cold sand is conveyed to from the water pipes for heating exchange. the sand will be conveyed out when reach the set temperature. 8. dust collector dedust ...
