Provide sample preparation services for laboratory professionals, researchers and engineers around the world.
Features and advantages
●The high-performance control design, many mechanical pulverizers that exceed the economical fineness limit, the micro-powder machine can continuously produce particles as small as 0.25 microns.
●•Support FDA-verified documents (IQ/OQ/PQ).
The crushed material can have a particle size distribution like "Gaussian curve"
● Consistent and tight particle size distribution, better suspension, dispersion and absorption
●It is convenient for manual disassembly, and no tools are needed to realize cleaning and sterilization.
● Pollution-free design can be ground into nano-level powder
●No heat generation: It is suitable for processing heat-sensitive materials.
●Easy for cleaning, product replacement or sterilization.
Can be designed as superheated steam as crushing medium
working principle
The grinding area of the FEM laboratory spiral jet mill is in the central chamber of the jet mill, and the grinding process does not involve grinding media. The raw materials are uniformly fed through the feeder, and the materials are sucked into the grinding chamber through the negative pressure generated by the gas injected at the end of the feeding port. The material rotates at a high speed in the cavity along the set direction, so that the materials collide and rub against each other and grind the materials. Centrifugal force keeps the larger particles in the jet mill crushing area until they reach the required fine particle size. The centripetal force drags the required particles to the static classification zone, and after reaching the required particle size, enters the receiving tank.
use
It is suitable for dry ultra-fine grinding of various brittle, crystalline, heat-sensitive, medium and low hardness materials. Used in chemical, pharmaceutical, food and other industries, with high yield and no dust spillage.
