Bentonite preparation facilities for drilling mud

The utility model discloses a bentonite preparation facilities for drilling mud, the former mineral aggregate of ca bentonite carry and carry out the intensive mixing to the agent of kolleroang and sodiumization, supplementary additive and water and roll behind crushing and screening, carry again to the modified back of trans variable -pitch propeller extruder extrusion, through the masking -out push semi -manufactured goods, again through the sunning crocus pack for drilling mud bentonite finished product. The utility model discloses a trans variable -pitch propeller extruder is modified, and the material is by two sections variable -pitch propeller forward propulsion, and the extrusion force strengthens gradually, has effectively solved the not enough production difficult problem of bank sum of products extrusion force, and is not only modified effectual, steady quality moreover, the preparation of bentonite for the mud that specially adapted oil drilling and prospecting well drilling were used. 本实用新型公开了公开了
