Overview

Particle strength tester is a material property testing instrument. Its core function is to reveal the intrinsic mechanical properties of materials at the microscale (single particle level), such as compressive strength, brittleness, toughness, etc. This is different from macroscopic powder characteristics such as "stacking strength" or "angle of repose".

Product Details

The particle strength tester is far from a simple "crushing" tool. It is a powerful material characterization platform that provides micro mechanical insights for many fields from pharmaceuticals, chemical engineering to cutting-edge materials science by accurately measuring the mechanical properties of individual particles and combining them with in-depth statistical analysis.

The DL4 particle strength tester ensures the accuracy and stability of testing in various aspects such as force control, data sampling, and data analysis calculation. The instrument has the advantages of small size, direct reading of measurement values, high accuracy, and easy use. It is an ideal new generation of testing instrument for determining the strength of samples such as fertilizers, drugs, catalysts, and particles. Widely used in the determination of crushing strength of spherical, strip-shaped, and columnar rigid materials such as catalysts, molecular sieves, adsorbents, etc. in the coal and metallurgical industries, as well as in the chemical, pharmaceutical, and petroleum industries.

It is a comprehensive product combining microcomputer technology, electronic technology, and mechanical technology. It uses a single-chip microcomputer as the control core of the entire instrument, high-precision force sensors as force detection elements, high-precision length measuring devices as length measuring instruments, and precision operational amplifiers to ensure linear processing of analog signals. The use of a single-chip microcomputer, with its real-time sampling, judgment, analysis, and comparison, has enabled the accuracy of the instrument to reach a certain level. This instrument has high accuracy, comprehensive functions, simple operation, and a high cost performance ratio. The instrument has the functions of data storage, repeated display, and calculation, without calculation errors, ensuring the accuracy of the calculation results. After the test is completed, you can also connect to the printer and print out the 'Strength Test Report'.

Printers and measuring instruments need to be purchased separately.

The specifications include 1000N, 2000N, 5000N, 10000N (10KN/), etc. Like any measuring instrument, attention should be paid to the range range when selecting and using it.

Technical specifications of DL4 particle strength tester:

Product Specifications	1000N	2000N	5000N	10kN
Zui Power Value Load	1000N	2000N	5000N	10000N
The largest sample size	60mm
Relative error	±1％
display resolution	1N
Zui Big Data Storage	2000 samples
Multiple working modes	The instrument provides four working modes, which can be set according to different usage situations: 1-Ball shaped sample testing; 2-Radial testing; 3-axis testing; 4- Measure reactor pressure
Abnormal data processing	Abnormal data processing can be set up, providing three ways of exclusion: 0- Do not exclude; 1. Remove one maximum and one minimum each; 2- Remove two pieces each of the largest and smallest ones
Low intensity value setting	Can set a lower limit value for qualified indicators (low intensity value) and participate in calculations
Calculation function and display mode settings	It can calculate the mean intensity, standard deviation, coefficient of variation, and low intensity percentage. Provide two display modes for selection according to different needs: 1. Display all (raw data and calculation results); 2- Only display the calculation results.
Printing function and printing mode settings	Connect the printer to print the strength test report of the original data and calculation results. Provide two printing methods to choose from according to different needs: 1. Print all (original data and calculation results); 2- Print the calculation results.
Excessive travel protection	The instrument is designed with an over range protection function, effectively protecting the force sensor from overload force loading. When measuring samples with over force values, the pressure head automatically returns and the data is invalidated.
working power supply	220Ｖ ±10％ 50Hz
Total power consumption	≤200Ｗ

Key considerations for instrument selection and standardization of testing:

1. Selection points:

Force range: Select based on the approximate strength range of the sample to be tested, ensuring that the range matches (such as 10N, 50N, 100N, 500N).

Accuracy and Resolution: The force resolution should be at least 1/5000 of the full scale or higher.

Loading speed control: There must be a wide range and precise controllable loading speed.

Software functionality: Does it provide powerful statistical analysis, Weber distribution fitting, data export, and other functions.

Compliance with standards: Whether the instrument complies with or is compatible with relevant industry standards (such as ASTM, EP, USP).

2. The importance of standardized testing:

Sample selection: The particle size and shape should be as uniform as possible.

Sample quantity: Statistically, at least 30-50 particles need to be tested to obtain a meaningful distribution.

Loading rate: It must be fixed and recorded, as the loading rate can affect the measured strength values.

Environmental conditions: Temperature and humidity may have a significant impact on the strength of certain materials (such as pharmaceutical particles, food), and it is necessary to test or record environmental parameters in a controlled environment.
