Slurry crushing and mixing process

Abstract

The invention relates to the field of ceramic processing, and particularly discloses a slurry breaking and mixing process, which comprises a clay raw material preparation step, a stirring device preparation step, a mixing stirring step, a conveying and ball milling step and a sedimentation and re-stirring step. According to the sedimentation and re-stirring step, installation rings are coaxially arranged on ejection rods to maintain the relatively states of connection rods, and first cutter blades are positioned below blades; when the installation rings contact the rubber strips on the ejection rods, the installation rods and the ejection rods are relatively fixed, and the ejection rods stir a mixture B at a rotation speed of 100-200 r / min while the connection rods are pushed to downward move at a speed of 3-10 cm / s; and when the first cutter blades contact the bottom portion of a stirring barrel, the moving of the connection rods is stopped. According to the present invention, with the technical scheme, the clay precipitated at the bottom portion of the stirring barrel can be rapidly and stably stirred.

Description

technical field [0001] The invention belongs to the field of ceramic processing, and in particular relates to a pulp crushing and mixing process. Background technique [0002] The raw material of ceramics is generally pottery clay, which is a kind of clay used to produce pottery and porcelain. Before use, the clay is put into a stirring device and mixed with water to form a slurry, and then ball milled after the slurry is formed. , screening, iron removal, pool storage and other operations. After the pottery clay is dissolved in the stirring device, the pottery clay is easy to settle at the bottom of the whole device, and it is difficult to completely stir the pottery clay with a general stirring rod.

Problems solved by technology

After the pottery clay is dissolved into the stirring device, the pottery clay is easy to settle at the bottom of the whole device, and it is difficult to completely stir the pottery clay with a general stirring rod

[0003] Especially after shutting down at night, the remaining clay in the mixing device will remain in the mixing device. The clay at the bottom of the mixing device is in a state of sedimentation and compaction, and the stirring rod is also buried by the clay. The motor that drives the stirring rod to rotate is forced to start. At this time, the rotation is difficult, which will easily cause the transmission of the motor to be invalid, and then cause the corresponding gear to be damaged. In severe cases, the stirring mechanism of the stirring device will be damaged. If this happens for a long time, the service life of the stirring device will be greatly reduced.
