PLC Control System Green Sand Moulding Machine Resin Sand Production Line

Resin Sand Production Line

The features of the equipment are advanced technology, reliable performance, rational structure, flexible layout, simple application and maintenance. The PLC control system is applied to realize mechatronics integration system. At present, there are 16 series, more than 80 kinds of production for the regeneration production line of resin sand sodium silicate sand and meet the demand of annual 1000 - 30000 tons of resin sand and sodium silicate-bonded sand.

Main Equipment

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 wear-resisting 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 double-arm of machine rotates flexibly and the available working area is large. The open type sand mixing stir cage is advantage for cleaning or adjusting the blade. The dust collection and deflavour system are combined in the primary and secondary connection as well 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.
