. Project Feature
1. The source of the production raw materials is widely with no regional restriction. The product is made of sawdust, straw (rice hulls), many kinds of crop straw and inorganic material (such as talcum powder, infusorial earth and powder coal ash) after special technology. So this project have low production cost, small investment and fast effectiveness.
2. The equipment has high automatization degree, simple production technology, low labor intensity and production line, and there is no noise and three-wastes (waste water, waste gas and waste residue) during production.
3. Low production energy consumption. With the influence of chemical reaction, it can meet the requirements about production technology without high temperature and high pressure.
