Batch Sand Mixer For Core Making Using Resin Bonded Sand

SWIF-MIX

  • MODEL MX-250 batch sand mixerpm250a
  • Portable Mixer (optional stationary can be quoted)
  • 200 to 275 lb. capacity
  • Versatile size to service
  • Designed for big jobs in small foundries
  • Great for small jobs in big foundries

The Model MX-250 batch sand mixer was designed to fill the need for a machine that can go anywhere in the foundry. Its 200 to 275 pound capacity makes the Model 250 the right Mixer for small and large foundries, for industry, and for educational institutions.

The Swif-Mix MX-250 moves the convenience of portability right into your foundry operation, yet is able to deliver the same efficient, heavy-duty service you expect from a stationary mixer.

Portability and profits can move hand-in-hand. The increased convenience of wheeling the mixer from job site to job site can mean the difference between profitable jobs and losers. And there can be more numbers in the profit column because the efficiency of a full-scale operation does not have to be sacrificed for profitability.

It also has heavy-duty engineering. This means performance you can count on and the increased efficiency and profits which go along with dependability.

The Swif-Mix MX-250 Batch Sand Mixer Puts Many Fine Features On Wheels

  • Sealed, anti-friction ball or roller bearings throughout.
  • Abrasion resistant steel plows, faced at wear points with a smooth layer of tungsten carbide which is applied by oxy-acetylene torch.
  • Abrasion resistant, hardened steel crib and base liners for extra life. Nine gauge thickness is standard.
  • Retractable handles for added maneuverability.
  • Convenient chute height means convenient unloading – wheelbarrow can be rolled directly underneath.
  • Rolls to the job on 7.75 x 14 inch industrial type pneumatic tires.
  • Shipped fully assembled and ready to go to work.

SWIF-MIX

Swif-Mix offers two sizes, MX100 MX250, each designed for efficient operation at a particular batch size; as well as greater economy, greater durability, lower maintenance and minimum downtime.

Moreover, the low initial investment, coupled with the long life of the machine, makes the Swif-Mix Mixer the machine to choose for the greater return of investment.

SWIF-MIX

Engineered For True Mixing Action And Minimal Maintenance Expensemx250e

Like other sand handling equipment, sand mixing machinery is usually considered self-destructive. Swif-Mix solves this maintenance problem while delivering completely mixed sand. Those mixer components subject to excessive wear can be easily replaced during routine maintenance. Because of this innovative concept, downtime is reduced to a minimum and high output is maintained for a greater return on the dollars invested. All of this is packaged in a mixer that is simple in design, ruggedly built, economically priced, and that delivers high efficiency performance.

SWIF-MIX is Designed for More Efficient Mixing Action

To insure thorough mixing, sand plows aerate and continuously churn the entire batch, blending the catalyst and binder uniformly throughout the sand.

Reduced Weight Means Reduced Wear

In any machine, bearing wear and maintenance are directly related to the weight of its moving parts. Swif-Mix has engineered in durability by reducing weight. Multiple-lip sand seals located inside the vertical drive shaft housing also prevent sand from entering and damaging bearings.

mx250dCompare These SWIF-MIX Features with Other Mixers Adjustable Sand Plows

Abrasion resistant steel plows are standard on all models. In addition, plows are hard surfaced along the leading edge with a tungsten carbide layer applied by the oxyacetylene process. Both inner and outer sand plows are fully adjustable and designed to give maximum mixing action.

Removable Plow Assemblies
Simply pull one lock pin and the plow assembly can be lifted off the drive shaft. Any sand on the plow assembly can then be removed by tapping it on the floor or brushing with a whisk broom.

 

Simple to Use

  1. Load mixer with washed silicate core sand
  2. Power mixer for 10 seconds to level sand
  3. Scoop several depressions in sand and add catalyst
  4. Power mixer for 2 minutes to mix sand and catalyst
  5. Set timer for 2 more minutes and add binder through cover into dispersion funnel
  6. Discharge prepared no-bake core sand into container or at core station

dumpdoorDischarge Door Operates with One Hand
Opening the bottom discharge door is an easy one-hand operation. The plow action makes discharge automatic and makes the mixer practically self-cleaning. Discharge requires about ten seconds. During the mixing cycle, a flat rubber seal seal prevents leakage, and a simple cam lock “locks” the door. The door is adjustable to compensate for normal wear.
