Vu Integrated Sand Making System By Dry Method Barite
Dry Sand Dry sand is the type of green sand, from which moisture is being removed. Dry sand is made by baking or drying the mold made from the green sand in a decent oven. The dry sand contains a mixture of 15 to 20 of clay and silica. This sand has rigidity, thermal stability, and strength.Dry Sand Molds Dry sand molds are baked in an oven, (at 300F - 650F for 8-48 hours), prior to the sand casting operation, in order to dry the mold. This drying strengthens the mold, and hardens its internal surfaces. Dry sand molds are manufactured using organic binders rather than clay.Dry sand making process advantages (1) Fineness modulus and grading area adjustment Sand making machine and sand stone powder separator are equipped with frequency conversion speed control system, which can adjust the production mode according to the characteristics of raw materials, and achieve the quick and convenient adjustment mechanism.Dry-process Sand-making Plant Because there are many problems with conventional Sand-making technique and equipment, such as the wet-process sand-making technique often cause dust pollution and lots of waste water and sludge, what’s , due to the unreasonable gradation and flat strip shape of particles, the quality of the manufacutred sand.
