Although grinding is considered one of the more established manufacturing processes, it is still relatively poorly understood. In particular, the interaction of the wheel with the workpiece at times seems more like an art than a science. In this presentation, a 3-D topographic measurement approach which encompasses both the wheel and the workpiece will be presented. The topographic information obtained from the wheel will be applied to a model to predict the workpiece surface generated which will then be verified by experimentation. The prelimi ....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

Abstract :

This project is on Plastic grinding machine which is an electrochemical machine used for granulating waste of plastic into small parts that can be reused for recycling in the same process as a fresh raw material . This minimizes the reduction in the production process and cost effectiveness. It is working on the principle that the raw material is cut by the shearing force on the material between fixed and rotary blades. The small cut pieces pass out from the sieve plate fixed in the body.

This machine has been used i ....etc

ABSTRACT
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. Af ....etc

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
