BT-1500 centrifugal sedimentation particle size analyzer
1. Introduction to centrifugal sedimentation particle size analyzer
The BT-1500 centrifugal settling particle size analyzer adopts various settling methods such as gravity settling, centrifugal settling, and their combination. Through clever design, the centrifugal device and measuring device become an organic whole, making the instrument have the characteristics of wide testing range, easy operation, fast and accurate speed, and real-time computer control of the testing process. It is an ideal particle size detection instrument in production, scientific research, teaching and other fields.

2. Testing principle of sedimentation centrifugal particle size analyzer

The settling method is a method of measuring particle size distribution based on the different settling velocities of particles of different sizes in a liquid. Its basic process is to put the sample into a certain liquid to make a suspension of a certain concentration, and the particles in the suspension will settle under the action of gravity or centrifugal force. The settling velocity of large particles is faster, while that of small particles is slower. The relationship between settling velocity and particle size is described by Stokes' law.

3. Basic characteristics of BT-1500 centrifugal sedimentation particle size analyzer
Integrating gravity settling and centrifugal settling, with a wide testing range and easy operation. Specially suitable for particle size testing of ultrafine kaolin and ultrafine heavy calcium. Adopting high-precision dual speed synchronous motors, the speed is stable and reliable, with a low failure rate. Combined with unique synchronization technology, continuous testing is achieved while high-speed centrifugation, ensuring the repeatability and accuracy of the instrument. By using the RS232 (serial port) standard interface for data conversion and transmission, various desktop computers or laptops can be easily connected to the instrument with just one signal line, completely bidding farewell to the traditional board connection method. The report has three different formats in Chinese and English, including cumulative particle size distribution data and curves, interval particle size distribution data and histograms, typical particle size values (such as D3, D10, D25, D50, D75, D84, D90, D97, D98), and so on. The format, layout, color, and font of the report can be edited as needed.
