The GS High Efficiency Rotor Sand Mixer is an innovative marvel in sand mixing technology, boasting three national patents and an optimized design that sets it apart. Specially crafted for the mixing of green sand, this mixer operates on a cutting-edge principle where a high-speed bottom scraper generates a dynamic circular flow of materials. The rotor blade, also spinning at high velocity, exerts impact and shearing forces, facilitating rapid interaction and friction among sand grains. This results in swift and efficient sand mixing, producing loose sand without the need for additional loosening machinery. Perfectly tailored for mechanized molding machines, when paired with a screw feeder, grid dosing device, and automatic water filling system, it evolves into a seamless automatic sand mixing unit, continuously supplying sand for molding operations. Its design is an epitome of simplicity and compactness, ensuring easy maintenance and operation, combined with economic efficiency, durability, high load capacity, and outstanding productivity, even under load starting. The sand's critical performance metrics – compactness, wet compression strength, and air permeability – consistently hit the mark, meeting all industry standards.
Components of the GS High Efficiency Rotor Sand Mixer:
1. The primary motor transfers its power to the reducer via a European-standard belt pulley. The reducer's output shaft is seamlessly coupled with the column using a chain coupling. The spindle drives the crosshead in a counterclockwise rotation, creating a dynamic ring flow of sand facilitated by the scraper device.
2. Two rotor mechanisms are symmetrically affixed to the circular crossbeam, each driven by the main motor through a v-belt and gears following a second deceleration. This setup ensures the sand mixing rotor rotates counterclockwise, working harmoniously with the scraping plate to apply essential impact, shear, and friction to the sand.
3. The reducer's transmission gears are crafted from large modulus alloy steel, hardened for extended service life. Additionally, a magnetic oil plug captures iron foam within the reducer. The sand mixer's bottom plate is lined with faience cast stone, recognized for its smoothness and wear-resistance. Scraper inserts are fortified with wear-resistant carbide, and the inner liner ring uses stainless steel or high molecular polyethylene to resist sand abrasion.
4. The unloading mechanism features an automatic air unloader, achieving a sand mixing cycle average of just 3 minutes per mix. Upon completing the mixing of green sand, the unloading port automatically discharges the material, eliminating the need for manual intervention and significantly boosting time-efficiency.
5. The GS High Efficiency Sand Mixer comes equipped with an automatic water injection system. Armed with an adjustable water pump, it fine-tunes the water injection mechanism based on the sand mixing volume. Following initial setup and calibration, it automatically injects water according to each batch's wet sand mixing volume, ensuring precise water distribution ratios.
6. Atop the GS High Efficiency Rotor Sand Mixer, a grid dosing device or electronic scale is installed, enabling precise automatic material addition every time. Additionally, an exhaust hole is strategically placed to facilitate dust removal and heat dissipation.
7. The reducer is strategically pressed and mounted on the base. During maintenance, simply disconnect the chain coupling and move the main motor away from the coupling's insertion section. This enables horizontal removal for repair, without dismantling the column or other critical components.
