GS high efficiency rotor sand mixer is a new type of sand mixer which adopts three national patents and optimized design. It is mainly used for the mixing of green sand. The main working principle is that the bottom scraper rotating at high speed pushes the material to form a circular flow in the machine basin, and the rotor blade rotating at high speed applies impact force to the sand and shearing force to the sand with the scraper, so that the sand grains can make fast contact and strong friction with each other, thus achieving fast sand mixing speed and loose sand without sand loosening machine, especially suitable for mechanized molding machine, combined with screw feeder, grid dosing device and automatic water filling system, it can It is especially suitable for mechanized molding machine, combined with screw feeder, grid dosing device and automatic water filling system, it can realize automatic sand mixing unit and provide continuous sand for molding machine.

The machine has the advantages of simple and compact structure, easy maintenance and operation, economy, durability, high loading capacity, high productivity, and load starting. The sand performance (compactness, wet compression strength and air permeability) can be realized to reach the qualified index.
