foundry clay sand production line
1. Belt conveyor
This conveyor is a new type designed according to the special application of casting plant. It is mainly used
for conveying the new sand, used sand, molding sand, coat and lime stone as well as the construction material,chemical industry and food processing for all granular or block shape material.
2. Multi-function vibration regenerator
This regeneration machine is designed for the resin sand or silicate bonded sand regeneration. The main
mode is vibration and friction regeneration, also the function of breaking sand shakeout, sieving, demold.
3. Bucket elevator
This machine is a vertical transferring machine which is applied in mechanical casting plant. It is mainly used
for elevating the used sand, waste sand, new sand, cleaning iron shot, etc. Combined with the belt conveyor
and other devices, we can design many kind of transferring system. The features are small external size, less
volume and higher elevation level so that the layout drawing will be compact.
4. Centrifugal regenerator
The centrifugal machine adopts the principle of dry process centrifugal regeneration. It is mainly used for used resin sand regeneration. The used sand will be
thrown to wearresisting lining by the high speed rotating blade. And the inert cover on the surface of resin sand will be removed by the rub and collision process between the sand articles, blade and box. According to the
process requirement, the process will be repeated for many times till the target achieved.
5. air-float separator
The separator is mainly used for separating the powder from the sand of resin sand and sodium silicate
sand. The powder should be completely removed from regenerating sand, so that the regenerating sand may
meet the process requirement.
6. Double-arm sand mixer
The machine is applied to mix the resin sand and silicate bonded sand. The 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. T
he 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
