Non underground mining
coal deposits are mainly divided into the following three steps: 1 ore deposit to develop cutting blocks of Preparatory; 3 recovery...
Mineral deposit development: a series of roadways are drilled from the surface to reach the ore body, forming a complete production system such as lifting, transportation, drainage and power supply.
Acquisition: Digging the roadway at the stage of development, dividing the stage into nuggets, and forming mining preparation work for the production system of the nuggets (pedestrians, ventilation, transportation, rock drilling and ore mining, etc.).
Cutting: refers to the opening and cutting of free surface and free space in the already completed ore, creating work for blasting and ore mining conditions for mining.
Mining: refers to the process of mining ore in a mined piece that has been approved for cutting. Grinding Machine
The grinder is a machine tool that uses abrasive tools to grind the surface of the workpiece. Most of the grinders use high-speed rotating grinding wheels for grinding processing, while a few use other abrasive tools such as oilstone, abrasive belts and free abrasives for processing. With the increase in the number of high-precision and high-hardness mechanical parts, as well as the development of precision casting and precision forging processes, the performance, variety and output of grinders are constantly improving and growing, so HOSTON grinding machine can provide you with grinding solutions in various fields.
