S20 Series Bowl Type Resin Sand Mixer Automatic Sand Mixing Equipment for Core Making

Product Description

Foundry Bowl Type Resin Sand Mixer Machine

Self-hardening sand bowl type sand mixer is a simple type of sand mixer, mainly used for small resin sand casting workshop, S20 series resin sand bowl type sand mixer is intermittent automatic sand mixer, its sand mixing in the bowl container, through the special high-speed stirring blades, to give the sand body with three-dimensional vortex movement, can make the sand and resin binder, curing agent in a very short period of time in order to fully and uniformly mixed, to get high-quality cold core box Resin sand. Resin dosing device and sand transfer car can be equipped.

In a small resin sand casting workshop, the sand mixing efficiency and sand mold quality directly affect the casting yield and production cost. The S20 series resin sand bowl type sand mixer has become the core equipment for cold core box resin sand preparation with its three-dimensional vortex mixing technology and intermittent automatic control. This article will deeply analyze how the equipment can help enterprises achieve small batch and high-precision casting production with the performance indicators of mixing uniformity > 98% and single sand mixing cycle ≤ 90 seconds from the dimensions of technical principles, process adaptability, core advantages and industry applications.

S20 Series Bowl Type Resin Sand Mixer Automatic Sand Mixing Equipment for Core Making

1. Technical principles and core design breakthroughs

Based on the mixing characteristics of resin sand (AFS 50-70, LOI 1.5-3.0%), the S20 series achieves technical breakthroughs through vortex dynamics optimization:

Three-dimensional vortex mixing system:

High-speed stirring blades: dual-axis different speed design (main blade speed 800-1200r/min, auxiliary blade 400-600r/min), forming vertical and horizontal bidirectional shear force, sand body movement speed of 5-8m/s, mixing uniformity increased to more than 98%;

Bowl-shaped container: bionic spiral surface (volume 0.1-1.5m³), sand retention time shortened by 30%, single sand mixing cycle ≤90 seconds, production capacity of 8-15t/h.

Precise proportion control:

The resin dosing device (metering accuracy ±0.5%) is linked with the curing agent injection module, and the resin/sand mass ratio control error is less than 0.3%, which is suitable for a variety of binders such as furan resin and phenolic resin;

The temperature compensation algorithm (ambient temperature -10ºC~45ºC) ensures that the resin viscosity fluctuation is ≤5%, and the curing reaction stability is improved by 40%.

Modular expansion capability:

Sand transport vehicles (load capacity 500-2000kg) and PLC control systems (supporting Modbus-TCP protocol) can be integrated to build an integrated production line of "sand mixing-transportation-molding";

The sand mixing bowl is designed with quick disassembly (replacement time <15 minutes), which is suitable for special sand molds such as chromite sand and gem sand.

2. Comparison of core advantages and economic benefits

Compared with traditional drum sand mixers, the S20 series achieves multi-dimensional upgrades through energy efficiency optimization and intelligent control:

Energy consumption and cost advantages:

Permanent magnet synchronous motor (power 7.5-22kW) combined with variable frequency drive, energy consumption per ton of sand ≤1.2kW·h, 30% energy saving compared with similar equipment;

Resin utilization rate increased to 99%, annual binder cost savings of more than 100,000 yuan (based on 500 tons/year).
