Length GraderAlso known as the Rice Selecting Grader or Broken Rice Separator, this state-of-the-art machine meticulously sorts head rice and broken rice with unparalleled precision. It eliminates roll stones and barnyard grass, even those with similar diameters, ensuring a flawless rice selection process.and
specific gravity with rice, etc. This indispensable machine is typically utilized in the final stages of rice processing in a factory, ensuring the highest quality output.,
It is also capable of grading other grains, even those with up to 30% impurities, demonstrating its incredible versatility.
This model boasts exceptional adaptability and superior separating efficiency, making it a top choice for performance-oriented operations.During operation, the separator tank position can be easily adjusted, ensuring a consistent and stable separation effect. The enclosed work cylinder design not only facilitates the installation of a suction system but also effectively prevents dust dispersion.
Main Structure and Working Principle:
The machine is composed of a robust frame, feeding house, main shaft, cylinder, screw, separator tank, discharge ring, sleeve spindle, discharge end bearing house, discharge end lid, and control elements such as the rotor arm, handwheel, and screw rod, as depicted in the attached figure.
Rice enters the cylinder through the feeding house. One end of the main shaft is supported by the feeding support, while the other end is supported by the discharge end bearing house via the bearing and sleeve spindle. The cylinder is fixed to the main shaft at the feeding end lid, with the other end supported by the discharge ring bearing on the sleeve spindle. The screw blade, attached to the main shaft, rotates in unison with the cylinder. The separator tank is supported by the main shaft bearing at one end and anchored to the sleeve spindle at the other, allowing them to rotate together. The sleeve spindle is supported on the discharge end bearing house by a bearing, with one end fixed to the rotor arm, the control element for the separator tank. The Length Grader operates with the main shaft driving the cylinder and screw to rotate in harmony, while the separator tank's position is adjusted externally via the sleeve spindle and control element.
This machine employs a single cylinder to sort broken rice and head rice with exceptional effectiveness.
