Description
Technical field
The present invention relates to sanitary ceramics field, and in particular to the ball-milling technology of Ceramic Slurry for Sanitary Ceramics.
Background technology
Existing Ceramic Slurry for Sanitary Ceramics be according to formula by hard material (such as feldspar, quartz), soft material (such as kaolin,
Washing china clay etc.) weigh, it is put into milling apparatus and is processed by a ball milling together；Such a ball milling method has following lack
Point：First：Raw material in formula, their grindability can have very big difference, due to the soft material such as clay class in itself
Grain graininess it is very small, in process can self-dispersing, need not again by attrition process repeatedly for a long time,
And hard material then needs several times even longer milling time to can be only achieved the fineness of requirement；Second, soft material and hard material one
When playing ball milling, due to more than soft doses and viscosity is high, hard material can be wrapped up, so that causing the profile of hard material becomes round and smooth, pole
The earth reduces the processing efficiency of the grinding step of hard material；3rd, prolonged ball milling can also destroy the particulate knot of soft material
Structure, so as to reduce the qualification rate of semi-finished product, finished product；To sum up, the mode of a ball milling, consumes substantial amounts of process time and electricity
Can, production efficiency is significantly reduced, and cause the qualification rate reduction of semi-finished product and finished product.
The content of the invention
In order to solve the above problems, the invention provides a kind of Ceramic Slurry for Sanitary Ceramics ball-milling technology, the technique can significantly drop
Low energy expenditure, improves production efficiency and product qualified rate.
To achieve these goals, technical scheme is as follows：
A kind of Ceramic Slurry for Sanitary Ceramics ball-milling technology, comprises the following steps：
Step one：By hard material and soft material category filter；
Step 2：Raw material, 900-1350 parts of hard material, soft material 600-950 parts, water 540- are weighed by following parts by weight
860 parts, 25-45 parts of waterglass, 3-12 parts of alkali face, wherein, the clay in soft material is no less than 150 parts；
Step 3：By the raw material weighed, sort for once enter abrasive material and it is secondary enter abrasive material；It is described once enter abrasive material by with
Bottom is grouped into：900-1350 parts of hard material, 360-600 parts of water, 150-300 parts of clay, 15-30 parts of waterglass, alkali face 3-12
Part；It is described it is secondary enter abrasive material be part in the raw material weighed in addition to once abrasive material is entered；
Step 4：Load ball milling in first time ball milling, ball mill and once enter abrasive material, ball milling 6-9 hours obtains primary
Mud；Wherein, it is described once to enter abrasive material and the cumulative volume of ball milling accounts for the 2/3-3/4 of ball mill volume；
Step 5：Second of ball milling, by 1/3rd primary mud with it is secondary enter abrasive material put into ball mill, ball milling 30-
50 minutes, obtain two grades of mud.
Further, the mesh screen residue of primary mud 325 is 8-10%；
Further, two grades of mud 325 mesh screen residue is 3-5%, and particle mean size is 5-6um, granularity>30um grain
Sub- 6%-10%, granularity is 30-10um particle 25%-35%, granularity<10um particle 55%-65%.
Further, ball milling is high alumina ballstone, and inner liner of bowl mill is high aluminum liner.
Technical scheme of the present invention is relative to prior art, the beneficial effect of acquirement：
(1) during this technique mud ball milling, it is initially charged with after hard material ball milling multiple hours, the granularity for reaching requirement, adds
Soft material, through a small amount of time ball milling, reaches the well mixed purpose of various raw materials, you can put mill；On the one hand, when can save ball milling
Between more than half, be that enterprise greatly reduces electric power energy consumption, reduce production cost；On the other hand, the ball-milling technology can improve ball
Efficiency is ground, mud production efficiency is improved.
(2) mud disposably ground is because of soft material long-time ball milling, and its particle is levigate so that mud integral particle is partially thin,
It is partially thin in grain composition, and the mud processed by technique of the present invention, more reasonable, the granularity of its grain mixture ratio composition
>30um particle 6%-10%, granularity is 30-10um particle 25%-35%, granularity<10um particle 55%-65%, keeps away
Destruction of the long-time ball milling to soft material particle is exempted from, the original grain structure for maintaining soft material (especially washes china clay, height
The laminated structure of ridge soil)；Hard material after ball milling, its particle refinement so that mud overall particle size specific surface area increases, its surface
It can also increase, mud plasticity enhancing, dry tenacity increase, processing characteristics is more excellent, burn till porosity reduction, finished product mechanical strength is carried
Height, product qualification rate lifting, therefore the mud of ball-milling technology production can improve the qualification rate of semi-finished product and finished product.
(3) present invention adds fraction clay in first time ball milling, can prevent hard material from precipitating；In ball milling, add
Degumming agent alkali face and waterglass can improve grinding efficiency.
It is (4) described once to enter abrasive material and the cumulative volume of ball milling accounts for the 2/3-3/4 of ball mill volume during first time ball milling,
With more efficiently using ball mill volume and improve the grinding efficiency of ball mill.
(5) because ball-milling technology of the present invention uses secondary ball milling technique, therefore by controlling the primary mesh screen residue of mud 325
For 8-10%, two grades of mesh screen residues of mud 325 are 3-5%, so as to finally go out the mud residue rate of mill in suitable scope, this hair
The bright residue rate is obtained by the mesh screen residue of mud 325, residue rate height can cause shaping eat slurry accelerate, semi-finished product intensity drop
Easily there is the problems such as pore, out-of-flatness in low, finished product Ceramic glaze, and residue rate is too low, may result in and eats slack-off, the semi-finished product of slurry
Go out to split to increase etc. defect.
(6) ball milling is high alumina ballstone, and inner liner of bowl mill is high aluminum liner, and anti-wear performance more preferably, can be carried greatly
High grinding efficiency.
