Production process: the process is: grinding - Separation - Roughing - Selection - winnowing dust collection. Dry sand sand production equipment, mainly on machine, crusher, vibrating screen. The technological process of ore after knock into smaller stone processing stone, stone mill processing through sand, and then through the vibration sieve, using a bar magnet and magnetic iron and iron in the process of screening, storage and packaging. Water sand production, the main equipment on machine, stone mill, barn, vibration sieve, waterway system etc.. The process is as follows: the color sand aggregate after knock into smaller stone processing stone, stone after stone roller compacted into sand, water stop rolling, water sand flow sedimentation tank, the tank in the sand into the barn baking dry sand, and then through the vibration sieve using a bar magnet, and the magnet iron removal in the process of screening, storage and packaging.
