Doublestar Idea: First & Develop & Open
SZ25,SZ26 series medium Continuous No Bake Sand Mixer
No Bake Sand Mixer is suitable for the equipment of continuous mixing resin sand, sodium silicate sand, red mud sodium silicate, organic grease. It is also suitable for core molding and molding of small resin self-hardening sand. It is mainly made up of big arm, small arm, bottom rotary table, resin bucket, curing agent bucket, electrical system, sand quantitative device, gas-liquid system and so on. The mixing is even, continuous, high efficiency.
1) Less wearing for sand mixing groove lining plate and blade.
2) Small amount of heat while mixing, evenly sand mixing
SZ28/ SZ29 series mobile Continuous No Bake Sand Mixer
SZ28/SZ29 series mobile Continuous No Bake Sand Mixer adopts medium speed sand mixing theory. Sand mixing groove lining board and blade wearing is less, heat small while mixing sand, good sand mixing continuity and uniformity, higher efficiency. The structure of machine is mobile continuous, big arm machine is motorized rotation. Small arm machine is manual rotation, reducing the labor intensity of operating workers. Big arm is rotating transmission, reducing the environmental pollution: Small arm is sand mixing stirring stage, resin and curing agent mix according to atomization device in this stirring stage. Liquid material quantitation adopts high precision gear pump and import diaphragm metering pump, which makes adjusting is more convenient and higher precision. It can adjust according to different process characteristics, electrical control system adopts PLC control.
SD25,SD26 series low speed Continuous No Bake Sand Mixer
This No Bake Sand Mixer is used for the continuous mixing self-hardening equipment. It is suitable for small and medium self-hardening core molding and moulding.
Fixed low speed continuous sand mixer adopts low speed sand mixer theory. So it makes sand mixing continuous and even. It is high efficiency, blade small wearing and so on.
S23 series double sand three mixing No Bake Sand Mixer
This No Bake Sand Mixer is used for the equipment of continuous mixing resin sand. It is suitable for core molding and moulding of medium and large resin self-hardening sand.
Binder supplying system adopts Italian import diaphragm pump, gear pump and liquid material reversing valve. Even if it has viscosity fluctuation , it also can make sure binder and quantitive accuracy≤±2.0%
Adopt the new process of double groove low speed premixed stirring stage.
Big arm is motorized rotation. It is equipped with limiting device.
The button on the head of sand mixing arm button control station can lift up and down. It is convenient for manual operation.
Electric control system adopts programmable controller. Working is reliable and convenient for operation and maintenance.
