Special Tread Rubber Extruder size 120mm (Developed as middle size between 4½" and 6" ) having 30 HP AC Drive, feed roll arrangement, circular head giving output or 400 to 450 kgs per hour with Nitra Hardened screw and sleeve.
Special wide mouth Extruder size 125mm, L/D 14:1 having mouth size 610mm x 30mm output 600 to 650 kgs per hour.




FEED ROLL :
In the conventional Extruders the material is fed through hopper having tangential under cut, which dose not accept hard materials, hence output is low. With incorporation of feed roll device, Extruder efficiency increases by 20%. The feed roll takes drive from special Nitra Hardened cone gear mounted on the scroll. With this attachment auto feeding of Extruder from over head conveyor becomes easy, totally avoiding the attention of the operator on the Extruder. With this special multi roller safety hopper are provided to avoid accidents. 


A SPECIAL CIRCULAR HEAD DEVELOPED FOR TREAD RUBBER PRODUCTIONS INSTEAD OF TWO PIECE CONVENTIONAL HEAD OFFERS FOLLOWING ADVANTAGES:
In the conventional head once the extrusion process is stopped the material weighing around 1½ to 2½ kgs is either wasted or this cured compound is mixed in to the to the to-be processed lot thereby lowering the quality. This happens because it takes a very long time to open the head and clean. First time in India SANTOSH has developed circular head which can be opened simply by unfastening the four yellow colour nuts as shown in the picture. The  head can be opened in a short time less than two minutes and not a gram of material remains inside the head. Already renowned parties like M/s. General Rubbers, M/s Midas Apco, M/s. Anchor  Treads Private Ltd., M/s India Rubber Ltd. are using the new type of heads. This heads can also be retrofitted on old machines.
