  • Introduction

          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.    Y335D 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. 

       Width of belt:500mm

       Conveying speed:1m/s

       Parallel transfer volume:50m3/h

       Power of motor:1.5kW

    2.    S561 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. 

       Production rate:1-3 t/h

       Power of motor:2*1.5kW

    3.    Y3715 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.

       Production rate:3-8 t/h

       Power of motor:1.5kW

    4.    S522II 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.

       Production rate:3-5 t/h

       Power of motor:2*3kW

    5.    S562III 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.

       Production rate:3-5 t/h

    6.    S255T 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. 


       Primary rotating radius:2.75m, Rotary scope:120°

       Power of motor:2.2kW

       Secondary rotating radius:1.75m(flexible), Rotary scope:270°

       Power of motor:4kW

    7.    S524IV 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.

       Production rate:3-5 t/h

    8.    HD8980 Bag-type dust collector

           The series of bag-type dust collector is specially designed for dedusting at the roof or bottom of cement plant storeroom, belt conveyer and collecting dust in a small area and it is also used for dedusting in the industry of casting machinery processing, metallurgy, ceramics, glass, heavy chemicals and food processing. The advantages of dust collector are little volume, large amount of air processing, compact structure, convenient application, strong reliability and so on. This equipment has a good dust collecting performance for large proportion of metal borings, sand for casting and medium proportion of powder.

       Processing air volume:5200-6000m3/h

       Filter area:40m2

       Rated power of fan:15kW

  • User Requirement

           According to the production program, workshop structure and technical requirements, the alkaline phenolic resin and organic material are applied as binder, adopt normal temperature cured resin sand molding process to manufacture heat resistant steel.

       Productivity: Steel casting parts 1000ton per year

       Regeneration capacity of used sand:1-3t/h

       Recovery rate of used sand:≥95%

       Regeneration sand demold rate:≥26%

       Ignition loss of regenerated sand:≤3.5%

       Powder content of regenerated sand:≤0.8%

       The capacity of mixing sand:5t/h

       The efficiency of removing dust:≥98%
