SAND CASTING EQUIPMENT.

GS14 rotor sand mixer adopts the sand mixing method combining low-speed scraper and medium-speed rotor, the green sand is mixed evenly and the comprehensive performance of the sand is good, it is equipped with automatic water filling device, and the quantitative sand mixing can be achieved with the grating quantifier or electronic scale, and the sand mixing efficiency can reach 3-60 T/H. The pneumatic discharge valve is adopted to realize the automatic sand discharge in the side direction, and the top is reserved for the exhaust hole.

S14 rotor sand mixer is a sand mixer with 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 rotates at high speed to push the material to form a circular flow in the basin, and the rotor blade rotates at high speed to apply impact force to the sand and shear 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, loose sand, no need of 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.

S14 Series Rotor Sand Mixer composition：
1.The main motor drives the reducer input through the European standard belt pulley, and the output shaft is coupled with the column by chain coupling. The spindle drives the crosshead to rotate counterclockwise, so that the scraper device pushes the type of sand to form a ring flow.
2.Two groups of rotor mechanism are fixed symmetrically on the cross beam of the circle, each driven by the main motor through the v-belt and gears after the second deceleration of the sand mixing rotor counterclockwise rotation, and with the scraping plate to apply impact, shear and friction to the sand.
3.The transmission gears in the reducer all adopt large modulus alloy steel hardened gears with long service life, and the reducer is equipped with magnetic oil plug to capture the iron foam in the box; the bottom plate of the sand mixer is paved with faience cast stone, which is smooth and wear-resistant; the scraper inserts are welded with wear-resistant carbide, and the inner liner ring is made of stainless steel or high molecular polyethylene for anti-sand treatment.
4.The reducer is pressed and installed on the base, when overhauling, disconnect the chain coupling and move the main motor out of the insertion part of the coupling, it can be pulled out horizontally for repair without dismantling the column and other parts.
