The Total Trough will vibrate with the help of the springs mounted with the base frame and Trough, due to the vibration produced the sand particle will move from its place and it will discharge through the discharge open.

The Sand preparation is one of the important activity in the Foundry. In this, the sand is prepared for the manufacture of the Mould. The return sand from the return sand hopper is discharged through an uniform arrangement fed into the feeder belt conveyor for charging the sand into the two way chute. The New Sand from the hopper is conveyed to the Intensive Mixer through the two way chute by a vibro feeder kept below the New sand hopper discharge portion. After receiving the return sand, new sand and additives as a batch through Two way chute, the batch hopper will deliver the sand into the mixer shell. At the time of mixing the water will be automatically added into the shell and the mixing will be made uniform. After completion of the mixing process, the sand is delivered and fall into the surge hopper. From Surge hopper, the prepared sand is conveyed to the Moulding sand hoppers kept above the Moulding machines through the distribution belt conveyor.The surge hopper allows only uniform controlled sand to travel on the distribution belt conveyor. At distribution belt conveyor, Straight ploughs are placed for diverting the prepared sand into the Moulding Sand hopper.

The SSEC Tumblast cleaning machine offers favourable, convincing solutions for blast cleaning of small and medium size work pieces, in batch quantities. the TB series will accommodate batch weights of 180 kg to 1360 kg. The applications of these machines are especially variable :Blast Cleaning of iron castings, precision castings, and die castings. Descaling forgings or heat-treated work pieces. Shot peening for surface compaction. Deburring of metalic (e.g. stampings) and non-metalic work pieces. Surface finishing. Tumblast cleaning machines have been successful over several years and in thousands of applications, often in multishift operation. The TB series have proved to be economical for low production and optimum blast cleaning. The TB series offers the following advantages :Attractive Price / Value ration Rugged, Compact design Ease of operation High blast cleaning performance Quick and easy replacement wear parts DESIGN AND SEQUENCE OF OPERATIONSDepending on the weight, size volume, and flow rate of the castings to be cleaned, the machine can be loaded in a manual, mechanical, or automatic mode. The work pieces are then tumbled inside the blast cleaning chamber consisting of a continuous troughing rubber belt conveyor and lateral discs of highly wear resistant material. Specially designed rubber belt conveyor assure gentle tumbling and full exposure of all surfaces. Burrs, scale, or sand drops passes through the perforations to the bucket elevator and the separator. After passing through the separator for removal of impurities, the abrasive returns to the storage hopper. Mechanical loaders are used for the machine on special request. The Shot blast machines can receive the parts to be cleaned directly or using separate transport bins of the standard sizes. SSEC blast wheels are renowned for high capacity and maximum energy efficiency. These blast wheels come in various power ratings, giving a high degree of flexibility. With modifications it is possible to reverse the blast wheel rotation thus allowing a greater range of applications. The amount of abrasive can also be adjusted. The abrasive is mechanically pre-accelerated and delivered to the blast wheel in a continuous stream, this ensures optimal utilisation of the power from the drive motors. High wear resistant material ensures maximum service life of the blast wheel. Unique features allow for rapid and simple replacement of wear parts.

Mixing Blade mounted on output shaft of the bearing housing and coupled with the gearbox for smooth running. Periodical coating on blade surface with hard facing electrodes or with tungsten carbide brazing yields longer life. The curvature of blades ensures perfect mixing and makes it possible to discharge the entire mixed sand and keep the surface clean to receive the next quantum.  

Blending Blade rotate at high speed and in opposite direction to mixing blades. Additives are perfectly mixed and sand particles are evenly coated all around.  

The Shots separation is done in two stages. First stage by means of magnetic drum and the second stage by means of Air distribution system. The Magnetic drum separates the shots and dust in two levels. In the first level, the shots are evenly distributed with the heh of a screw feeding system by which most of the shots are separated and fed to the Air distribution system. The shots which are not picked up by the first level of the Magnetic drum goes to the second level for separation the shots are directed to the machine and the dust is collected separately.  

SSEC Heavy duty sand Mixer / Muller are of sturdy construction and easy to maintain. The adaptation of a successful procedure to modern requirement of sand preparation at increased rotary speed and adjustable pressure.

The inside of the shell is welded with longitudinal flights for ease of travelling and  effective drying. 

Return Sand Temperature, after the vibratory shake out in a mechanized green sand foundry is around ZOOGC. The sand temperature is highest arbacent to the metal surface and lowest away job it. The quantity of heat to be removed depends on the sand to metal ratio and the holding time of metal in the mould. The return sand temperature at the inlet of the cooled after passing through conveyor is around 1 OOOC. Mould of good quality and clean casting surface require well cooled sand,Sand Cooling requires a continuous and uniform flow to achieve the uniform flow and compensate for irregular Sand supply the sieved hot return sand is stored in a surge hopper from there; a belt transports the hot sand to the cooling conveyor which is designed with a perforated bottom plate. Fresh air is blown through the preparation holes and at the same time water is sprayed on to the sand from nozzles located above the conveyor vibrations of the conveyor and turbulence caused by the air blown through ensure that sand water mix well so that The water evaporates and the sand is cooled. The belt, the cooling conveyor and the sand spraying unit are controlled by level indicators located in the surge hopper the plant operates only if the sand in the surge hopper is between the maximum and minimum level.

SAND RECLAMATION PLANTThrough out the most Industrialized countries of the World, increasing environmental concerns and the costs of purchasing quality moulding sand make the recycling or reclamation of the used sand more attractive. To make acceptable moulds, several conditions of recycled sand must be achieved. The sand must be restoted to a condition where The grain size distribution The binder content on the grains The presence of foreign materials and metals. The moisture content. The Temperature all meet certain standards The reclamation system that allow the foundries to recycle upto 95% of the sand. Cutting New Sand addition down to as low as 5% without a loss in Mould quality. The Primary method SSEC uses to achieve these results is Attrition reclamation, that is wearing of binders from the sand grain through mechanical means. When the residual binder level is more the tensile strength of the mould surface finish are all lowered. SSEC Reclamation system removes the binders without damaging the sand grain structure or increasing the dust content in the sand. The main advantage of SSE C Reclamation system is that it produces rebondable sand at the lowest cost of per Ton of any other system achieving similar quality. The Reclamation system consists of Shakeout Lump Breaker Sand Elevator Sand Attrition unit Sand Cooler/ Classfier Dust Collection System Salient Features Shakeout Dis - integrates bigger lumbs by means of vibratory Motors.
