The screening analyzer separates pulp fibers through standard screens to analyze their length distribution. Morphological parameters such as fiber length and coarseness directly affect paper properties like strength and bulk. The screening process includes dispersing the pulp sample, grading and screening, weighing, and calculating, yielding key data such as average fiber length and fines content. These results are used to guide refining processes, furnish proportions, and quality control, serving as an important basis for optimizing paper production. Operations must follow standard methods to ensure accurate and comparable results.

The freeness tester is used to evaluate the drainage performance of pulp suspensions by measuring the amount of water filtered or the time required under specific conditions, indirectly reflecting the drainage characteristics of the fibers. Its testing follows international standards, with the core components including a standard screen and a measuring device. During operation, it is essential to control the pulp concentration and temperature, and regularly clean the screen to ensure accuracy. The freeness value is influenced by factors such as fiber length and fine fiber content, and it can be used to guide the refining process, balancing the drainage performance and strength requirements of the paper. Regular maintenance and calibration are crucial for ensuring data reliability.

Both the beater and the grinder are equipment used for material processing, but their core functions differ. The beater is primarily used for processing fibrous materials, such as pulp, altering the fiber morphology through shear forces to enhance bonding performance, with the key metric being the beating degree. In contrast, the grinder focuses on refining granular materials, such as minerals or food ingredients, to achieve the desired particle size, with the core parameter being the grinding fineness. During equipment selection, it is essential to base the decision on material characteristics: choose a beater for fiber processing and a grinder for particle refinement, while also considering process requirements and operational costs comprehensively.

The slurry disintegrator is a laboratory pre-processing device primarily used to disperse and break down solid samples in a liquid to form a homogeneous suspension for subsequent testing. It separates particles through mechanical shearing, turbulence, and other mechanisms, making it suitable for applications in materials science, chemical engineering, food processing, papermaking, and environmental testing. During operation, parameters such as rotational speed, processing time, and medium properties must be controlled to ensure reliable sample processing, and relevant operational guidelines should be followed.
