In manufacturing processes in industries of foods, chemicals, pharmaceutics, new energies, and others, there has been a problem that has perplexed countless technicians: how to process raw materials to make the outcome finer, more uniform, and more stable?
If there is insufficient fineness in food pastes, it causes their taste to diminish; if there is insufficient uniformity in chemical suspensions, it raises concerns on their stability; if there is insufficient particle sizes in active pharmaceutical ingredients, the drug produced would have low efficacy.
All these problems ultimately point to the same core issue: grinding fineness, which is why the innovation in micro-nano level grinding technology is leading to a qualitative leap in the field of fluid processing.
For a straightforward comparison, 1 micrometre is equivalent to 1/80 of the diameter of human hair, while 1 nanometre is 1/1000 of 1 micrometre. As the particle size of any raw material gets reduced to micro-nano level, the material’s specific surface area drastically increases, causing fundamental changes to its key indicators, such as activity, solubility, stability, and taste.
In pharmaceutics industry, finer particle size means a higher utilization rate on materials; in food industry, fineness determines the product’s taste and smoothness; in new-energy industry, micro-nano level dispersing technology is an important stepping stone to industrialized manufacturing of graphene and carbon nanotube materials.
Thus, whoever gains a first-mover advantage in micro-nano grinding technology, is guaranteed to achieve a decisive edge in quality competition. SGN Machinery, knowing the importance of micro-nano grinding, has consistently innovated in this field, and is currently an industrial leader on this path.
The core technology that helps SGN Machinery achieve micro-nano-scale grinding can be summarized as the combined action of three crucial factors.
The first factor is ultra-high linear speed. SGN’s equipment features ultra-high linear speed and rotation speed, causing the material to receive drastic mechanical shearing forces in an extremely short amount of time, which lays a foundation for nano-scale grinding.
The second factor is precise rotor-stator structure. SGN’s equipment has accurate, adjustable rotor-stator gaps. Some of SGN’s most advanced machine units consist of three or more stages of rotor-stator groups — as the raw material passes through, it is sheared, dispersed, and ground at multiple stages, where it becomes progressively finer, eventually its particle size reaches micro-nano level.
The third factor is optimized fluid dynamics structure. SGN’s specially designed working chamber is able to generate strong turbulence via high-speed spinning, causing the material’s granules to frequently collide with other granules or hit the rotor-stator, which further reduces the particle size.
High linear speed provides energy foundation, precision structure ensures grinding fineness, and fluid design improves efficiency. It is the deep integration of these three factors that allows SGN equipment to establish a technological advantage in the field of micro-nano grinding.
SGN has created a comprehensive array of standalone machine products covering the shearing, grinding, homogenizing, dispersing, mixing, and other steps of processing. A selection of core equipment is shown below:
