Development of an energy efficient rotary kiln for the production of expanded slate aggregates from slate waste

Objetivo

To prepare a step 2 submission to design and build a kiln to produce expand slate aggregates from slate waste based on the design for a prototype kiln prepared under the framework 4 craft programme (development of expanded slate for horticultural and aggregate use) contract n° BRST-CT97-5210. The batch and tunnel kilns used for that programme are not suitable for production purposes but have provided the technical knowledge necessary to design and energy efficient rotary kiln which combines the use of gas and micro-wave energy and incorporates the time and heat parameters which the research showed were required to expand slate waste. The aim of the project is to demonstrate that an aggregate, which is suitable for use in a wide range of building materials and meets EU building product specifications, can be produced economically. The production would include a concrete block which would have twice the strength, four times the insulation value and yet only half the weight of a traditional block. The project would demonstrate the world-wide suitability of the plant for exploitation in the slate industry and the great environmental and economic benefits that would accrue.
