Precision Grinding Excellence - Technological Breakthrough of WF-20B Laboratory Crusher
Date: 2025-08-14Read: 3
As a core pre-processing equipment in the pharmaceutical and food testing fields, the WF-20B laboratory grinder developed by Jiangsu Guolang Machinery redefines industry standards through three technological innovations. Its 4500r/min high-speed spindle, combined with a 304 stainless steel toothed disc, can achieve freely adjustable grinding fineness of 10-120 mesh, meeting the particle size requirements of Chinese Pharmacopoeia for traditional Chinese medicine powder.
Core technological advantages
1. Modular dust removal system
By adopting pulse back blowing dust removal technology, the dust collection efficiency reaches 99.6%, which reduces energy consumption by 40% compared to traditional bag dust removal. The cyclone separator and stainless steel mesh form a secondary filtration system to ensure that the sample purity meets GLP laboratory standards.
2. Intelligent temperature control design
The water-cooled circulation structure can control the temperature of the crushing chamber at 25 ± 3 ℃, avoiding the loss of activity of thermosensitive components (such as volatile oils). The measured data shows that the temperature rise of the material does not exceed 5 ℃ after continuous operation for 4 hours.
3. Human computer interaction upgrade
Equipped with a 7-inch touch screen, preset with 12 material crushing programs, supporting closed-loop adjustment of pressure, speed, and time. The historical data storage function facilitates the traceability of experimental processes and complies with the electronic record requirements of FDA 21 CFR Part 11.
Typical application scenarios
Traditional Chinese Medicine Research and Development: Complete the ultrafine grinding of 50g of Panax notoginseng roots in 30 minutes.
Food safety testing: achieve non cross contamination treatment of samples such as nuts and spices.
Chemical new materials: Pre treat nylon particles to achieve uniform particle size, with a CV value of less than 8%.
This device has passed CE certification and GMP compliance assessment, and its compact body is particularly suitable for use by third-party testing institutions and university laboratories. With the advancement of intelligent transformation projects, the new generation of models will integrate AI visual sorting and 5G remote operation and maintenance functions.
