Sand Preparation Systems

Sand Mixers

The Sand Mixers from Mingzhi Technology are available as batch or high-speed units. Depending on your core production requirements, all our mixer lines can feed single or multiple core machines.

• Batch Mixer

Our MSC batch mixer is available either as a stand-alone device or may be mounted on a trolley to feed multiple core machines. The round wall and bottom of the batch mixer are covered by a wearproof material that may be easily replaced. The mixer’s hard steel blades are treated and removable and they rotate by means of a motor gear. The sand outlet gate opens and closes using a pneumatic cylinder. This batch mixer features a translation motion driven by a gear motor, that includes a frequency device for speed adjustment.

• High-Speed Mixer

Our MSA high-speed mixer is a stand-alone device suitable for feeding a single machine. Through the addition of a belt or trolley, multiple core machine feed is also possible. A fast cycle time allows for mixing small quantities of sand and binders. The round wall is covered by a wear-proof material that may be easily replaced. This mixer’s hard steel blades, which are treated and removable, spin horizontally by means of a motor gear. The sand outlet gate opens and closes by means of a pneumatic cylinder.

Binder Dosing

Our volumetric resin-dosing device guarantees precision and repeatability. Volume levels are measured by means of a capacity sensor positioned along the calibrated dosing tube.

Our centralized binder supply system allows customers to have a dedicated room for storing commercial binder drums. This system supplies the binder to the heated tank situated near the mixer.

Sand Heater

Our sand heater, known as the Fluid bed heater system, is used for heating and dedusting the sand. It is installed between the weighting system and the mixer. 

The sand at an input temperature of 5° can be heated to a constant temperature of 20- 25°. The hourly output ranges from 1,5 to 5,0 ton/h.
