Overview

The particle strength tester is a specialized instrument used for accurately measuring the compressive strength, wear resistance, and impact resistance of solid particles (such as catalysts, fertilizers, pharmaceutical particles, food particles, chemical raw material particles, etc.). It is widely used in the research and development, production quality control, and academic research of chemical, pharmaceutical, new materials, food, environmental protection, and other fields. Its core value lies in providing data support for process optimization, product quality assurance, and material performance evaluation by scientifically quantifying the mechanical stability of particles.

Product Details

The particle strength tester is a specialized analytical device that accurately measures the compressive strength and crushing force of particles by applying vertical pressure until they rupture. It is used to evaluate the mechanical properties of individual particles or small batches of particle materials.

The DL5 particle strength tester is a new type of intelligent measuring instrument that achieves digital display. Suitable for measuring the crushing strength of spherical or cylindrical granular materials. This instrument has the advantages of small size, direct reading of measurement values, high accuracy, and easy use. It is an ideal new generation testing instrument for determining the strength of samples such as fertilizers, drugs, catalysts, and particles. It is widely used in the chemical, pharmaceutical, and petroleum industries to determine the crushing strength of small rigid materials such as catalysts, molecular sieves, and adsorbents.

The particle strength tester uses the principle of friction to place the material into a testing tube, which is then placed into a testing machine. The testing machine rubs the material in the testing tube to measure its particle size strength.

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 components, and precision operational amplifiers to ensure linear processing of analog signals. 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'.

The specifications are 50N and 150N. Like any measuring instrument, attention should be paid to the range when selecting and using it. It is generally recommended to select the force range of the tested sample within 10% to 90% of the full range. If the range is greater than 150N, please choose other models of our company's products.

Main application areas:

1. Pharmaceutical industry

Tablet hardness testing: This is a classic application used to test the hardness of tablets, ensuring that they are not easily broken during production, packaging, and transportation, while also ensuring that they can disintegrate as expected in the body.

Capsule and pellet strength testing.

2. Chemical and catalyst industry

Catalyst strength determination: Catalyst particles need sufficient strength to withstand the pressure and friction in the reactor, preventing pulverization from causing an increase in bed pressure drop and a decrease in activity.

Strength testing of molecular sieves and adsorbent particles.

3. Food industry

Testing the hardness of grains, candies, pet food pellets, and puffed foods is directly related to taste and product quality.

4. New energy materials

Test the strength of battery positive and negative electrode material particles, study their structural stability and preparation process.

5. Building materials and metallurgical industry

Test the compressive strength of ceramic balls, refractory particles, carbon products, etc.

6. Research and Education

Used for scientific research and teaching experiments in fields such as materials science and chemical engineering.

Core measurement parameters:

measurement metrics	Definition and Application Scenarios
Compressive strength (single particle/stacked particle)	Single particle: measures the maximum pressure value (unit: N, MPa) at which a single particle reaches fragmentation under axial pressure, suitable for key particles such as catalysts and tablets; Stacked particles: measure the compressive strength of a certain amount of particles after stacking, suitable for scenarios such as particle beds and fillers
Wear resistance strength	Measure the wear rate (unit:%) of particles during simulated transportation, storage, or use through rotation, impact, friction, and other methods to evaluate the anti powdering ability of particles
impact strength	Simulating the fragmentation of particles under instantaneous impact force, suitable for particle performance evaluation in high-speed conveying, pneumatic conveying and other scenarios
Particle size change rate	Combined with screening method, measure the changes in particle size distribution before and after testing to assist in determining whether the particle strength meets the process requirements

As the core equipment for evaluating the performance of granular materials, the particle strength tester's accuracy and stability directly affect product quality and process optimization effects. Choosing instrument models that are suitable for one's own needs and reliable domestic manufacturers can ensure the reliability of test data while reducing procurement and usage costs.
