【Company Profile】 Nagao System INC. is a professional group that solves mixing, dispersion, and milling that was

previously considered impossible by utilizing high-speed 3D motion of our own 3D Ball Mill (3D Reactor).

The target is highly homogeneous mixture, dispersion of specific gravity, material with viscosity difference.

R&D enterprises, research institutes, universities that milling materials of mm or less to Nano, Microns.

Difference between high-speed 3D motion and high-speed 2D motion

High-speed 3D motion is non-critical. Non-agglomerated and non-solidified particles realized.

3D ball mill (3D Reactor) can mix substances of different specific gravities and viscosities

uniformly without using blades.

High speed 3D motion (No Critical) High speed 2D motion(Critical)

Criticality occurs in high-speed 2D motion.

Strong friction force motion utilizing the

whole container. There is no criticality.

【We’ve got a suggestion.】 We realize impossibility and done pulverization, mixture, dispersion by

manufacturing development of the industrial materials conventionally and strengthen your products.

Four Objectives of Thailand 4.0

1. Economic Prosperity: to create a value-based economy that is driven by innovation, technology and creativity. The model aims to increase Research and Development (“R&D”) expenditure to 4% of GDP, increase economic growth rate to full capacity rate of 5-6% within 5 years, and increase national income per capita from 5,470 USD in 2014 to 15,000 USD by 2032.

2. Social Well-being: to create a society that moves forward without leaving anyone behind (inclusive society) through realization of the full potential of all members of society. The goals are to reduce social disparity from 0.465 in 2013 to 0.36 in 2032, completely transform to social welfare system within 20 years and develop at least 20,000 households into “Smart Farmers” within 5 years.

3. Raising Human Values: to transform Thais into “Competent human beings in the 21sth Century” and “Thais 4.0 in the first world. Measures under Thailand 4.0 will raise Thailand HDI from 0.722 to 0.8 or the top 50 countries within 10 years, ensure that at least 5 Thai universities are ranked amongst the world’s top 100 higher education institution within 20 years.

4. Environmental Protection: to become a livable society that possesses an economic system capable of adjusting to climate change and low carbon society. The targets are to develop at least 10 cities into the world’s most livable cities, reduce terrorism risk, and increase the proportion

Characteristics

・Non criticality by high speed 3D motion

・High uniform mixing and dispersion

without blades

・Unused blades are not affected by shear

heat

・Reduced heat generation utilizing the

entire container

・Mixing and dispersing without

destroying the particle shape making use

of frictional force

Solidification in 2D motion dry pulverization, mixture, and dispersion. Solution:

Achieving no solidification by high-speed 3D motion dry pulverization, mixture, and dispersion. .

Thermogenesis problem in 2D motion pulverization, mixture, and dispersion. Solution:

Utilizing the entire inner area of the container promotes the dispersion of frictional heat and its generation. Effective with organic and inorganic substances.

Uneven particle size in 2D motion pulverization, mixture, and dispersion. Solution:

High-speed 3D motion is a batch type mixture that makes use of frictional force. Because it always moves around inside the container, there is no time to solidify.

Uneven 2D motion mixing (because of only one axis) Solution:

Without propeller/blade. High-speed 3D motion makes it possible to use entire inner area of container efficiently. Low thermogenesis and uniform mixing can be achieved.

【Merit in details ④Solution of the irregular】【Merit in details ⑤Mixing・Milling/Cohesion】


【Total cost 】2D motion, when mixing, fine particles move to the bottom. There are cohesion and irregular problems.

Therefore, after cohesion, work to unravel substances occurs.(Researchers' labor costs are expensive.)

In the high-speed 3D motion, the fine particles always move around the inside of the container at the time

of mixing, and do not give cohesion time.CAPEX ＆ OPEX
