Chemical type modified starch twin screw extruder with higher corrosion.

1.  Pregelatinized/Modified starch is an effective and economical fluid loss agent in water based drilling fluids, which is a starch derivative. It is not bacterial degradation when at 120℃, environmentally acceptable and non-toxic.

Ingredients: natural starch, such as corn starch, cassava starch, topiaco starch, potato starch, wheat flour, and other chemical type, such as carboxy methyi cellulose.

2. Modified Starch machinery can produce a thin, slick, tough filter cake and promotes faster penetration rates with reducer friction.

3.  It can be used in all kinds of drilling fluid systems, Paper system, Textile system and so on

4.  Parameter

5. It need equip the cooling tower

6. Screw materails : alloy high quaity for corrosion. , barrel inserted alloy steel .

7. Inside water cooling, instead of the jacket type, control temperature exactly. suitable for the modified starch which request low temperature and stable type.

8. Flow chart: Mixer, elevator, extruder, cooling, crushing machine.
