Bowl Type Coated Sand Mixer: Precision and Efficiency in Foundry Operations
The bowl type coated sand mixer is a cornerstone of modern foundry technology, designed to produce high-quality resin-coated sand for manufacturing molds and cores in metal casting. By uniformly blending sand grains with binding agents (e.g., phenolic, furan, or cold-box resins), this equipment ensures consistent sand properties, critical for defect-free castings. Its unique bowl-shaped design optimizes mixing efficiency while minimizing binder consumption, making it indispensable in automotive, aerospace, and heavy machinery industries.
Bowl Type Coated Sand Mixer Application:
This Bowl Type Coated Sand Mixer is only used for mixing self-hard core sand and molding sand.
It can be used alone or combined with self-hardening sand equipment.
Bowl type coated sand mixer working process:
Bowl type coated sand mixer work mechanism two symmetrical sand mixing blade by the installation of the cross head, sand gear drive spindle high-speed rotation, driven in two blade with special spiral Angle,To the basin of ball mill, the material of strong mixing. Basin of machine adopts spherical on the one hand, can reduce the pile of sand blind Angle, is beneficial to increase the circulation of the sand flow, under the action of spiral vane, on the other hand, using the inertia of sand sand flow along the spherical upward, and then rolling down under the action of gravity, followed by a blade after throwing up. The sand mixing machine spindle speed is high, the blade casting diffusion of material flow friction and rolling effect is very strong.
Bowl type coated sand mixer features:
1, small volume, light weight
2, sand mixing evenly, it is the main equipment for making small resin sand and core, typical single use.
3, bowl type coated sand mixer used for resin and the intermittent sand mixer is generally located in the hemisphere sphere of sand mixing chamber to make it through the special high speed mixing blade, sand to eddy motion turns up, fixed blade hemisphere on sand will be reflected off again, such repeated cycle make sand and curing agent, resin sand binder mix quickly, and have the ball at the bottom of the sand discharge sand mouth, every time according to the quantity of sand and the binder, different kinds of viscosity, sand mixing time between 10 and 40 s.
4, bowl type coated sand mixer is a new type of high efficient sand mixer, mainly composed of sand of container, transmission system, discharging mouth. Used for casting sand core sand mixing, the characteristics of sand with high efficiency, short sand mixing cycle.
