Digital Cement Negative Pressure Sieve Testing Machine
- Product Description
Digital Cement Negative Pressure Sieve Testing Machine
Negative Pressure Sieve Testing Machineused for the determination of various types of cement in a certain negative pressure through a sieve sieve allowance, to determine the fineness of cement particles.is widely used to
determine cement fineness. Air flow takes the role as dynamic media. The whole system is under negative pressure, specimen under test will be in flow state under the action of airflow
sprayed by the rotating gas nozzel, and travel along with airflow. Fine particles whose size smaller than sieve aperture are extracted away,leaving particles whose size larger than sieve
aperture.

三、Structure principle
The negative pressure sieve analyzer is mainly composed of a box, a sieve base, a vacuum cleaner, a cyclone dust collection device and an intelligent digital display controller. The box is the main structure of the instrument. All parts and components are installed in the box. The sieve base is equipped with synchronous motors, nozzles, hard pipes, etc., and a test sieve and a sieve cover are placed on it. The lower end of the hard tube is connected with the air inlet of the cyclone with a hose, and a small port is connected to the negative pressure controller with a hose. The vacuum cleaner serves as the source of negative pressure.
