Fig. 1 is the overall procedure schematic diagram of the inventive method.
Embodiment
Below in conjunction with Fig. 1 the inventive method is described in further detail.
Referring to Fig. 1, the preparation method who is applicable to ceramic powder of the present invention sequentially comprises broken process, mixed processes, fine grinding operation, magnetic separation operation, granulating working procedure, granulation optimization operation, finished product drying process.In broken process, with hard raw material crushings such as quartz, feldspar, wollastonite, talcum, Wingdale, diopside, ceramic waste materiaves to less than the particulate material of 3mm, kaolin, wilkinite, illite, agalmatolite, black mud, etc. soft raw material will not be broken.In mixed processes, mix with soft raw material without fragmentation being crushed to less than the particulate material of 3mm.Mixed raw material can enter the fine grinding operation.Before with various mixing of materials, should require according to the prescription of the powder that will make various raw materials are carried out weighing and proportioning.The work of weighing and proportioning even can be arranged in before the broken process.
Before the fine grinding operation, preferably make water ratio through the raw material after the mixed processes≤10%, can so that powder is not easy caking in the fine grinding process, improve abrasive dust efficient thus.The mode of control water ratio can be natural air drying or heating, drying.
In the fine grinding operation, will become powder through the raw material fine grinding of mixed processes.As preferred forms, in the fine grinding operation, preferably adopt the high-pressure overhang roll formula grinding machine with warm air drying, and the hot blast temperature of this grinding machine is controlled between 30 ° to 500 °.This high-pressure overhang roll formula grinding machine with warm air drying has improved abrasive dust efficient so that powder is not easy caking in the fine grinding process.Moreover, this high-pressure overhang roll formula grinding machine with warm air drying has the function of dry and selection by winnowing two aspects, can in the fine grinding process, can carry out selection by winnowing to powder again to improve the abrasive dust effect by dry powder, guarantee to only have the powder that satisfies fineness requirement just can send grinding machine.
In the magnetic separation operation, can adopt dry-type magnetic extractor that the powder after the fine grinding operation is carried out deironing, to remove the iron contamination of in broken process and fine grinding operation, sneaking into powder because of mechanical wear.After deironing is finished, powder can be sent into the feed bin wait and enter granulating working procedure, perhaps also can immediately powder be sent into tablets press and carry out granulating working procedure.
In granulating working procedure, on one side preferably granulation on one side uses electronic metering pump to spray fog to powder, the atomizing pressure of electronic metering pump is 2～8kg/cm
2Electronic metering pump can accurately be controlled the height of powder water content, improves the granulation quality.The atomizing pressure of electronic metering pump is controlled in the described scope can be so that the granular size of granulation be just suitable, not too large can be too not little yet.Can make like this volume density of the particle that powder forms after granulation large, grating is more reasonable.
As preferred forms; in granulating working procedure, preferably adopt tilting powerful mixing tablets press to carry out granulation; and the Gradation Control of powder particle of the powder of tilting powerful mixing tablets press output is existed: 10～30 purpose particles account for 28%～35%; 31～50 purpose particles account for 38%～48%; 51～70 purpose particles account for 10%～18%, and 71～90 purpose particles account for 5%～10%.The Gradation Control of powder particle in this scope, can be reduced the gas content in the powder, increase the volume density of powder, improve the pressing speed of follow-up pressure brickwork order.Tilting powerful mixing tablets press mainly is comprised of mechanisms such as the adjustable high speed rotor mechanism of the deep bid rotating cylinder, the rotating speed that tilt, discharge mechanism, flow quantitative systems; eccentric position and turning direction that rotor mechanism is located at the deep bid rotating cylinder are opposite with the deep bid rotating cylinder; blade on the rotor mechanism is installed in the spiral step shape on the different heights of stir shaft, and scraper plate also is installed in the deep bid rotating cylinder.These constructional features of tilting powerful mixing tablets press are so that powder all obtains action of forced stirring on level and vertical direction, and powder is not only done the Sloped rotating motion but also spun upside down motion in granulation process, has eliminated the stirring dead angle, and can prevent the powder caking.In order to obtain best granulation effect, the external diameter linear velocity of the deep bid rotating cylinder of tilting powerful mixing tablets press is preferably disposed between 10～25 meter per seconds.
Between granulating working procedure and finished product drying process, be provided with granulation and optimize operation.It is exactly with vibration separation screen the powder of finishing granulation to be carried out classification that operation is optimized in granulation, is sent to the finished product drying process after screening larger particle is out pulverized again, and screening less particle out directly is sent to the finished product drying process without pulverizing.As preferred forms, to optimize in the operation in granulation, every fineness＜10 purpose particles all should be considered as larger particle.
In the finished product drying process, preferably adopt Vibratingfluidbeddrier that powder is carried out drying.Dried powder moisture control is between 6%～7%.Dried powder can be sent into the feed bin wait and make adobe.
