Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening technology, and in particular to a calcium carbonate powder separation device. Background Technology
[0002] Calcium carbonate powder separation devices primarily stem from the industrial demand for high-purity calcium carbonate. Calcium carbonate is widely used in building materials, chemicals, and pharmaceuticals, and its purity directly affects product quality. Traditional separation methods, such as gravity sedimentation and filtration, suffer from low efficiency, high energy consumption, and insufficient purity. With technological advancements, mechanical separation technology has gradually become mainstream. Its core principle is to separate powders of different particle sizes using centrifugal force or airflow. Modern separation devices typically employ high-efficiency cyclone separators or airflow classifiers, achieving efficient separation of calcium carbonate powder through precise control of airflow speed and centrifugal force. Furthermore, the introduction of automated control systems further enhances separation accuracy and stability, meeting the stringent requirements of industrial production for high-purity calcium carbonate.
[0003] Existing separation devices do not have the function of uniformly spreading powder in the screening chamber. When the powder is unevenly distributed on the screen, some areas may accumulate too thickly, causing screen blockage or slowing down the screening speed, thereby reducing the overall screening efficiency. In addition, there is no linkage function for the rotation of the screening chamber. If a rotating screen is not used in the powder separation device, it may lead to low screening efficiency, easy screen blockage, insufficient screening accuracy, accelerated equipment wear, increased energy consumption, and increased operation difficulty.
