Cryogenic grinding, also referred to as freeze grinding, is the act of cooling or chilling a material and then reducing it into a small particle size. For example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere in lumpy masses and clog screens. When chilled by dry ice, liquid carbon dioxide or liquid nitrogen, the thermoplastics can be finely ground to powders suitable for electrostatic spraying and other powder processes. Cryogenic grinding of plant and animal tissue is a t ....etc

Definition

The term Cryogenics originates from Greek word which means creation or production by means of cold. As prices for energy and raw materials rise and concern for the environment makes safe waste disposal difficult and Costly, resource recovery becomes a vital matter for today's business. Cryogenic grinding technology can efficiently grind most tough materials and can also facilitate Cryogenic recycling of tough composite materials and multi component scrap. The heart of this technology is the CRYO-GRIND SYSTEM. It employs a cryoge ....etc

Introduction

In every development process, there is a pressing need to increa¬
se the availability of qualified human resources. Developing
countries tend to experience a crucial lack in precisely this area.
In most countries, education in science and technology is recei¬
ving increasing attention, which indicates that development of
the teaching process is considered an essential task. High qual ....etc

ABSTRACT
An automotive propulsion concept is presented which
utilizes liquid nitrogen as the working fluid for an open
Rankine cycle. Ambient heat exchangers are used to power
an engine that is configured to maximize heat transfer during
the expansion stroke. If sufficient heat input during the
expansion process can be realized then this cryogenic
propulsive system would provide greater automotive ranges
and lower operating costs than those of electric vehicles
currently being considered for mass production.
The
feasibility of meeti ....etc

Cryogenic grinding permits heat-sensitive, thermoplastic, and elastic materials to be economically ground to very small particle sizes. The cryogenic process actually embrittle a material prior to size reduction and controls heat buildup in the grinding equipment. The result is high product quality and system productivity.
Cryogenic grinding involves cooling a material below its embitterment temperature with a cryogenic fluid, typically liquid nitrogen or, in certain applications, carbon dioxide. After cooling, the material ....etc
