Two types of mining equipment: 1. open-pit mining: low cost, high profits, mainly using digging machine Cinder rise, loaders scraper slag transport, car, air drills, explosives. 2. underground mining: the high cost of Diversion Project Cinder machine, you need to stand and tunnel ventilation, mine laying track, using specialized equipment train transport to the surface. As for the problem of rational use of resources, mine exploitation unit is generally difficult to achieve, will pollute the environment and damage during mining, and slag is basically useless, if the smelter, will the other elements in the ore separation out for any other purpose scraper transmission Cinder machine, slag machine, hsin rake slag provided by Gongyi City Xinhua Machinery Factory.
