Preparation system and application system for pollution preventing material and soil improving material consisting of mudstone essentially
专利汇可以提供Preparation system and application system for pollution preventing material and soil improving material consisting of mudstone essentially专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain a soil improving material or pollution preventing material rich in active constituents having a high adsorptivity, by predrying a raw mudstone with hot air, crushing the stone in a crusher, drying the crushed stone in a direct heating dryer, pulverizing the dried stone in a pulverizer, adding a paste nontoxic to men and cattle thereto, and granulating the resultant mixture in a granulator.
CONSTITUTION: A raw mudstone which is a naturally occurring porous clay mineral having a wide space between particles is mined, transferred and shelved in a hot-air dryer and predried. After the moisture of the raw mudstone is reduced to 22W25% (optionally by the natural drying), the stone is crushed by a crusher, and dehumidified and dried to a moisture content of 10W15% while being fed continuously to a direct heating dryer, e.g. a rotary kiln. The dried stone is then pulverized by a feed grinder or hammer mill to a particle size of 30W50 mesh and not to destory the components contained therein. A paste nontoxic to men and cattle is added thereto, and the resultant mixture is kneaded and granulated in a screw feeder granulator and then dried to give the aimed material.
