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.

In the Monorail type Shot Blasting Machine, comes with Manual movement or Motorised movement of hangers into Blasting cabin. The movement of hangers through the machine is achieved by a Transport system moving in intervals continuously. With the advantage of number of hangers, loading and unloading of castings becomes easy and can be carried out while the machine is in operation. The doors are provided with Hydro Pneumatic system, which makes the door to open when the cycle is completed and the hanger movement is ejected by this arrangemement. Until and otherwise the blasting is stopped, the door will not open and after closing of door only blasting starts, which makes safety to the working of the machine. During the blasting cycle, the hangers are placed in two positions, which makes the efficient cleaning of the casting.

Through 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.

Unique Design of in-built Sand Feed Technology. High Efficient double shell design rotary sand drier which ensures uniform sand drying.Wheels are mounted on the base frame in such a way that while rotation there will be no slippage or improper transmission of power from the gear unit to the shaft.One end of the shell is mounted in the combustion chamber and it is connected with oil tubes and blower pipelines.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.

The machine can be operated by simply pressing the cycle push-button when it is part of an automatic plant. When it is used as a stand alone machine. It is to be operated by means of a lever control distributor and a pedal by the operators. The Special anti-wear hard rubber coating of the surface contacting the support plate keeps the noise level below the limits allowed by law. Proper high efficiency pneumatic lifting shock absorbing devices, isolate the vibrating part from the floor preventing the vibrations being transmitted to the base. A pressure switch in the Pneumatic circuit stops the machine operation in case of low pressure inside the feeding circuit. The vibrating table can be eqippped with an "Inverter" providing a variation of the vibrating frequency to suit the compaction to the different types and sizes of moulds as well as to the types of binders used.
