A particle strength tester is an instrument used to measure the compressive strength of particulate materials. It is widely used in pharmaceutical, food, chemical, agriculture and feed fields to detect the hardness, brittleness and compressive strength of granular materials. This article will introduce the use of a particle strength tester in detail.
1. Instrument introduction
The particle strength tester is mainly composed of pressure sensors, measurement systems and controllers. The pressure sensor senses the pressure applied to the particles, the measuring system converts the pressure into an electrical signal, and the controller controls the measurement process and displays the measurement results.
Second, the use of the steps
1.Preparation
Before using a particle strength tester, you need to prepare the particulate material to be measured. The granular material is placed on a flat surface to ensure that the particle size, shape and surface quality are consistent for the accuracy of the measurement results. At the same time, it ensures that the granular material is dry and avoids the influence of humidity on the measurement results.
2.Install the sensor
Place the pressure sensor of the particle strength tester on the measuring table and adjust the height and angle of the sensor so that it is parallel to the contact surface of the particle material. Make sure the sensor is securely mounted to avoid shaking or shifting during the measurement process.
3.Set the measurement parameters
Set the measurement parameters on the controller, including the measurement range, measurement unit, sampling frequency, etc. According to the nature and requirements of the particle material to be measured, select the appropriate parameter settings.
4.Start measuring
Press the start button on the controller, the particle strength tester will automatically apply pressure to the granular material, and record the pressure and displacement data. During the measurement process, attention should be paid to the deformation of the particulate material to ensure the consistency of the measurement conditions.
5.Data processing and results analysis
Once the measurement is complete, the data is exported to a computer for processing and analysis. Depending on the actual needs, different data processing methods such as statistics, charts, etc., can be selected to obtain more in-depth analysis results. At the same time, the measurement results should be interpreted and evaluated in combination with the actual application scenarios and experimental purposes.
3. Precautions
1.During use, care should be taken to keep the instrument clean and avoid the influence of dust and debris on the measurement results. At the same time, the instrument is calibrated and maintained regularly to ensure the accuracy and reliability of the measurement results.
2.For particulate materials with different properties, appropriate measurement parameters and pressure ranges should be selected. Avoid damaging the structure of the particulate material due to excessive pressure, which can lead to distortion of the measurement results.
3.During the measurement process, attention should be paid to the deformation of the granular material to avoid affecting the accuracy of the measurement results due to the rupture or deformation of the granular material. If there is any abnormal situation, the measurement parameters should be adjusted or the measurement should be stopped in time.
4.In the stage of data processing and result analysis, attention should be paid to the interpretation and evaluation in combination with the actual application scenarios and experimental purposes. At the same time, attention should be paid to the accuracy of data statistics and analysis to avoid misleading follow-up research and application.
5.For measurements that require high precision, it is recommended to use more advanced instruments and technologies for detection and analysis. At the same time, attention should be paid to comparison and validation with other detection methods to ensure the reliability and accuracy of measurement results.
