S25 series double arm sand mixer  

 

 Mixing resin sand for foundry enterprises, a continuous operation of the core sand sand mixing machine, the machine is made of continuous mixing liquid curing agent and liquid resin or self-hardening sand core making use of resin sand mixer.Resin sand sand mixer can be divided into: arms resin sand sand mixer and single arm resin sand sand mixer.Arms resin sand sand mixer's most widely used, its characteristic is can be made up of free secondary rotary stirring cage, the first level is conveying stirred cage, conveying the original sand.the second level is high speed mixed sand stirring cage.Liquid resin and curing agent are in the second stage injection,first of all  injection curing agent, a period of time and then sprayed into the resin.

 

the resin sand mixer main component

Part of the resin sand sand mixer including: primary transport stirred cage, secondary sand stirring cage, PLC electrical control system, electric control cabinet operation, liquid system (including: curing agent, resin pump, liquid pump valve, etc.), gas path system, such as sand quantitative system components.

 

 

 Advantage of resin this type sand mixer

(a) Binder supply system adopts advanced electric variable diaphragm pump. Pump. Light weight, small 

Volume, compact structure, stable and reliable quality.

 

(b) Sand mixing evenly. Effectively ensure the quality of molding (core) and molding rate.

 

(c) the sand mixing time is short. Head backfilling. Less discharge clean.

 

(d) A mixed sand gathering for the open walls. Easy to get over walls. Blade cleaning and adjustment of 

the blade.

 

(e) Electric control system adopts PLC control. Set according to fully work. Protection and fault indication. 

Reliable work. Ease of operation.

 

(f) Arms swing. Operation with larger area.

Adhesive Quantitative Accuracy		<±2%

1. Supply system of the adhesive adopt advanced wheel pump, diaphragm pump and liquid detector, measurement accuracy.
 
2. Short mix time, no less sand from end to end, Double arms rotating flexible, large area of operation.
 
3. Open type sand mulling mix cage arm, easy clean and adjust leaf and convenient maintenance.
 
4. to set advanced fluidization boiling, the powder content of sand is further reduced and the quantity of adhesive is substantially reduced and improve the quality of the sand mixture and get good economic benefits. 5. The electrical devices adopt PLC control system, abundant confinement and protection. Simulation-screen display, stable and reliable working, to achieve automatic production.
