Shijiazhuang Xinlu Technology Co., Ltd. – Technical Overview of Rotary Vibrating Cleaner

The Rotary Vibrating Cleaner is a versatile and efficient machine used for the initial cleaning of various grains, including rice paddy, wheat, maize, and other cereals. Its primary function is to remove large, small, and light impurities from the raw, harvested grain, ensuring that the subsequent processing stages, such as husking or milling, are protected from abrasive contaminants and can operate at optimal efficiency. Shijiazhuang Xinlu Technology Co., Ltd. produces these cleaners with a design that emphasizes high capacity, effective screening, and reliable operation.

The machine's operation is based on a combination of a rotating cylindrical screen and a vibrating aspiration system. The raw grain is introduced into the inlet of the machine and is conveyed into the interior of a cylindrical screen assembly. This screen drum rotates at a moderate speed. The inside of the drum is often equipped with internal flights or ribs that lift the grain and cause it to tumble as the drum rotates. This tumbling action is highly effective in breaking up clumps and allowing smaller impurities to pass through the perforations in the screen. The perforations are sized according to the grain being cleaned; they are large enough to allow the grain itself to pass through but small enough to retain larger contaminants like straw, stalks, and cob pieces. These oversized impurities are gradually carried to the discharge end of the drum and ejected.

Simultaneously, an aspiration system is at work. A powerful fan creates a controlled air current that is drawn through the falling curtain of grain, either at the inlet or at a designated point within the machine. This airflow is calibrated to lift and remove lighter impurities such as dust, husks, chaff, and empty grains, which have a lower density than the sound grain. The removed light waste is transported through an air duct to a cyclone or bag filter for collection. The combination of the tumbling action inside the rotating screen and the aspiration provides a comprehensive cleaning action that addresses a wide range of impurities in a single machine.

One of the key advantages of the rotary vibrating cleaner is its gentle handling of the grain. The tumbling action is less aggressive than the sharp oscillations of some planar screen cleaners, which can be beneficial for delicate grains or seeds. The machine is also known for its high capacity and is often used as a primary pre-cleaner in large-scale processing plants. Maintenance typically involves periodic inspection and replacement of the screen drum if the perforations become worn or damaged, and regular cleaning of the aspiration ducts to maintain optimal air flow. The robust construction, featuring a solid frame and durable screening surfaces, ensures a long service life even in demanding industrial environments. The Rotary Vibrating Cleaner from Shijiazhuang Xinlu Technology Co., Ltd. thus serves as a fundamental first step in establishing a clean and efficient grain processing line.
