Product Overview
As domestic natural sand has been unable to meet the needs of the rapidly growing construction industry, the demand for artificial sand has increased rapidly. Jiangsu Tongzheng Machinery Manufacturing Co. Ltd. in the company owned by the national invention patent product TS series three separation powder machine based on the V type selection and combination of powder machine, made of TZ-SF composite artificial sand powder and winnowing machine. The product can be divided into four kinds of sand and powder of different thickness, which conform to the market demand and have been accepted by users. The product has been listed as the Ministry of science and technology Chinese "artificial sand winnowing powder removing machine industry innovation project".
This product has been applied to Wuhan Xinjinyu Building Material Environmental Protection Co., Ltd. project, Guizhou Zhongyi Building Labor Co., Ltd. project special artificial sand production.

Performance Features
1. Scientific separation principle: The product has multiple classification systems. Based on the characteristics of sand and gravel, the aerodynamic analysis method used in aviation is adopted to optimize the material flow design, which reduces the equipment operating resistance, achieves high separation efficiency, and results in remarkable energy saving and consumption reduction. It is superior to the traditional production process of water-washed sand and gravel separation.
2. The V-shaped dispersing and classifying zone has a simple structure and low consumable consumption. There is no electric dispersing device, resulting in small pressure drop loss, stable operation, and low power consumption.
3. High classification precision: A vortex rectifier is installed inside the powder remover. The airflow in the rectifier only rises without rotating relative to the rotor, and the materials are repeatedly cleaned in the classification zone, resulting in high classification precision.
4. Simple operation: The cage rotor adopts variable-frequency stepless speed regulation. It has a wide adjustment range and is convenient, sensitive, and reliable to adjust.
5. High classification efficiency: The "V"-shaped dispersing and classifying zone is equipped with multiple layers of dispersing and classifying plates for repeated dispersing and blowing off, so that there is almost no fine powder in the discharged coarse powder. At the medium powder discharge port in the settling and classifying zone, airflow blows away the fine powder in the medium material again, greatly reducing the fine powder content in the medium material. Guide vanes are added in the cage rotor classification zone, making the classification more accurate and effective.
6. Low maintenance workload and long service life for wear-resistant parts: The main wear-prone parts of the powder remover are made of imported wear-resistant steel plates, which effectively improves the service life. The entire machine has undergone dynamic balance calibration and runs smoothly over the full speed range.
7. A new design scheme is adopted for the lower bearing seal of the main shaft, which effectively solves the two major problems of dust entering the bearing and lubricating oil leakage, and practically and effectively prolongs the service life of the bearing.
8. When designing the foundation of the powder remover, the principle of mechanical vibration damping is adopted, so that the vibration frequency of the separator foundation does not form an integer multiple relationship with the natural frequency of the separator, fundamentally solving the long-standing resonance problem of the separator.
9. The coarse sand pipe, medium-coarse sand pipe, and fine sand pipe all adopt double interlocking air valves, which greatly reduces the air leakage rate of the system and overcomes the defect of large dust emission during the operation of the previous powder remover.
10. The system adopts double interlocking air valves and internal circulating air, which effectively reduces system air leakage and reduces dust emission pollution during operation.
