Embodiment 1

[0036] A method of resizing, comprising:

[0037] 1. Stir the new pulp.

[0038] 2. After passing through the vibrating screen with mesh 20, the new pulp after stirring is sieved once, and then poured into the new pulp container.

[0039] 3. The new pulp in the fresh pulp container is screened for the second time through a vibrating screen with a mesh size of 120.

[0040] 4. After the new pulp has been sieved for the second time by the electromagnetic separator, the new pulp is deironed, and then poured into three old containers.

[0041] 5. The new pulp is stale for 5 days in three stale containers.

[0042] 6. Pour the return slurry into the return slurry container.

[0043] 7. Pass through a vibrating screen with a mesh size of 120 to sieve the returned pulp in the returned pulp container.

[0044] 8. Use the electromagnetic separator to return the slurry after the slurry has been sieved and remove the iron, and mix it with the stale new slurry in the mixing container....

Embodiment 2

[0047] A method of resizing, comprising:

[0048] 1. Stir the new pulp.

[0049] 2. After passing through the vibrating screen with mesh 20, the new pulp after stirring is sieved once, and then poured into the new pulp container.

[0050] 3. The new pulp in the fresh pulp container is screened twice through a vibrating screen with a mesh size of 140.

[0051] 4. After the new pulp has been sieved for the second time by the electromagnetic separator, the new pulp is deironed, and then poured into three old containers.

[0052] 5. The new pulp is stale in three old containers for 8 days.

[0053] 6. Pour the return slurry into the return slurry container.

[0054] 7. Pass through a vibrating screen with a mesh size of 140 to sieve the returned pulp in the returned pulp container.

[0055] 8. Use an electromagnetic separator to return the slurry after the return slurry has been sieved to remove iron, and stir and mix with the stale new slurry in the mixing container. The stir...

Embodiment 3

[0058] A method of resizing, comprising:

[0059] 1. Stir the new pulp.

[0060] 2. After passing through the vibrating screen with mesh 20, the new pulp after stirring is sieved once, and then poured into the new pulp container.

[0061] 3. The new pulp in the fresh pulp container is screened twice through a vibrating screen with a mesh size of 130.

[0062] 4. After the new pulp has been sieved for the second time by the electromagnetic separator, the new pulp is deironed, and then poured into three old containers.

[0063] 5. The new pulp is stale in three old containers for 6 days.

[0064] 6. Pour the return slurry into the return slurry container.

[0065] 7. Pass through a vibrating screen with a mesh size of 130 to sieve the returned pulp in the returned pulp container.

[0066] 8. Use the electromagnetic separator to return the slurry after the return slurry has been sieved and remove the iron, and then stir and mix with the stale new slurry in the mixing containe...

Abstract

Disclosed is a slurry returning method. The slurry returning method comprises the steps of injecting returned slurry into a slurry returning container; screening and deironing the returned slurry in the slurry returning contained; mixing the processed returned slurry with obsoleted new slurry in a mixing container, wherein the new slurry is obsoleted for 5-8 days and stirred for 5-7 hours at a stirring speed of 10-14 rounds per minute, the mixed volume ratio f the returned slurry and the new slurry is 50%-55%: 45%-50%.

Description

technical field [0001] The invention relates to ceramic manufacturing technology, in particular to a slurry returning method. Background technique [0002] The production of sanitary ware is injection molding, such as figure 2 As shown, after each grouting is completed, about 50%-60% of the mud is returned to the raw material workshop to be mixed with the newly prepared mud, and then recycled after being stale (the newly prepared mud needs to be stale and homogenized for more than 5 days to achieve stable performance. And resizing does not need to go through the old homogenization process). The existing production process cannot satisfy the stability of mud performance. [0003] shortcoming: [0004] 1. Impurities in the returned slurry are not easy to find; [0005] 2. The mixing ratio of back slurry is uncontrollable; [0006] 3. Stale together with returned pulp, resulting in insufficient homogenization time for new pulp stale and unstable performance; [0007] 4. M...
