Working principle and core characteristics of laboratory ultrafine crusher
Date: 2025-05-26Read: 4
The laboratory ultrafine grinder solves the demand for fine processing in laboratory environments through technological integration, and its modular design and functional scalability have become an ideal choice for scientific research and small-scale production. Today, the editor will take you to understand the working principle and core characteristics of the laboratory ultrafine crusher.
1、 Working principle
1. Composite crushing mechanism
The laboratory ultrafine pulverizer combines mechanical impact and airflow pulverization technology, applying shear and impact forces to materials through high-speed rotating blades (such as polygonal tip knives), while using an airflow circulation system to quickly separate the crushed particles, achieving efficient pulverization and dynamic grading.
2. Dynamic grading and centrifugal separation
The material enters the grading zone driven by the airflow, and the centrifugal force generated by the high-speed grading wheel separates coarse and fine particles. Particles that meet the fineness requirements are collected by a cyclone separator, and coarse particles are returned to the crushing zone for further processing to ensure controllable crushing accuracy.
3. Low temperature protection and ultrasonic assistance
Some aircraft models use supersonic airflow or cold slurry technology to avoid local high temperatures and protect the activity of thermosensitive materials; Ultrasonic assisted technology further crushes materials through cavitation effect, reducing thermal energy accumulation.
2、 Core Features
1. Fine and controllable granularity
The fineness of plant-based fibers can reach 40-100 μ m (D98), while hard and brittle materials can reach 1-44 μ m (D98). Some models adjust the fineness over time (such as 300 mesh to 15000 mesh) to meet different scientific research needs.
2. Wide applicability
The special blade design is suitable for various materials such as traditional Chinese medicine, chemical industry, food, etc., and balances the efficient processing of fibrous and brittle materials.
3. Convenient and efficient operation
Continuous feeding design combined with automated sorting system, which can be operated by a single person; The compact size (which can be placed on the experimental table) and lightweight (such as 26kg) significantly improve the utilization of laboratory space.
4. Safety and environmental characteristics
The fully enclosed structure prevents dust leakage, and the sieve free design combined with wind selection principle reduces pollution risks. It is easy to disassemble and clean, meeting laboratory cleanliness standards.
5. Intelligence and Energy Efficiency
Adopting an intelligent control system to simplify the operation process, combining high-speed rotating blades with low-energy design, balancing efficient crushing and resource conservation.
