In the process of storing raw materials in a batching bin in the drying procedure, the dry hot air is pumped into the batching bin to reduce the water content of raw materials to be lower than 5 percent. And then, one or more dried raw materials are subject to the crushing procedure for being crushed into powder with a diameter of less than 0.125mm. Compared with the prior art, the semi-drying ceramic powder production method and device has the advantages of simple technique, small energy consumption, small investment, and low production cost.
Description
Technical field:
The present invention relates to a kind of production method and device of ceramic powder.
Background technology:
Existing semi-dry type ceramic powdery material production method is by the feeding machine burden process, ball mill abrasive material operation, the deironing of ball mill blowing, the operation of sieving, spray tower spraying drying operation, the old operation of raw material warehouse entry constitutes, in ball mill abrasive material operation, adopt ball mill that block raw material is ground to form fine particle, need add water, reach requirement so that grind the granularity of the ceramic powder that comes out, like this, what ball mill came out is the ceramics powder slurry, the ceramics powder slurry can not directly use, also need the slurry drying granulation, become ceramic powder, flowability during with increase moulding cloth, this kind production method, owing to need carry out drying to the ceramics powder slurry, therefore, need expend lot of energy.Therefore, the shortcoming of prior art is complex process, energy consumption height, investment is big, production cost is high.
Summary of the invention:
Goal of the invention of the present invention is to provide that a kind of technology is simple, less energy consumption, less investment, semi-dry type ceramic powdery material production method and device that production cost is low.
Semi-dry type ceramic powdery material production method of the present invention is to realize like this, in regular turn by broken process, storage procedure, pulverizing process, the powder iron removal step, granulating working procedure constitutes, in broken process, adopt jaw crusher that particle diameter is become the particle of diameter below 20mm greater than the raw material crushing of 20mm, then particle diameter is transported to less than the raw material of 20mm in the batch bin of storage procedure and stores, then, with a kind of or more than one water content is that raw material below 8% is sent to pulverizing process and carried out powder mix and be broken into meal below the 1mm, then, by the powder iron removal step iron substance in the powder is cleared out, the last continuous humidification mixer of drum-type that adopts in granulating working procedure is by evenly increasing the humidity of the little meal of particle diameter, the powder of meal is evenly united become to meet the bigger particle of diameter that the ceramic powder granular size requires, become the finished product ceramic powder with the requirement of the flowability that satisfies powder.
Here, adopt raymond mill that raw material is pulverized in the pulverizing process.
For the component content that makes ceramic powder meets service requirements, before pulverizing process or between pulverizing process, powder iron removal step or be provided with burden process between powder iron removal step, granulating working procedure, the burden process before pulverizing process is two kinds or two or more block raw material to be knocked down pulverizer according to ratio requirement pulverize or knock down raymond mill and grind; Come out in burden process is set is pulverizing process between pulverizing process, powder iron removal step two kinds or two or more meals mix according to ratio requirement, deliver to the powder iron removal step after mixing again and carry out deironing; Burden process is set is two kinds that the powder iron removal step is come out or two or more meals and mix between powder iron removal step, granulating working procedure, deliver to granulating working procedure after mixing again and further handle again according to ratio requirement.
For the ceramic powder steady quality that further guarantees to produce, the ceramic powder particle that obtains through granulating working procedure enters the ceramic powder ageing tower and carries out old.
Semi-dry type ceramic powdery material production equipment of the present invention is achieved in that in regular turn and is made of broken machine, first transfer roller, the batch bin that has Weighing mechanism, second transfer roller, raw material mixed organization, the 3rd transfer roller, pulverizing mill, the 4th transfer roller, magnetic separator de-ironing, the 5th transfer roller, humidification tablets press.Be provided with drying plant in batch bin, drying plant is the dry heat tracheae that has the air outlet, the air outlet be arranged on the dry heat tracheae around, batch bin is provided with the dehumidifier mouth, so that moisture is extracted.During work; raw material crushing with bulk becomes the particle of diameter below 20mm earlier; deliver to the batch bin that has Weighing mechanism by first transfer roller then; by feeding dry hot gas toward batch bin with the raw material stoving in the batch bin; different types of raw material that will come out from different batch bins is delivered to the raw material mixed organization and is mixed after Weighing mechanism is weighed; then mixture is delivered to raymond mill and be ground into meal below the 1mm, meal is delivered to the granulation of humidification tablets press after the magnetic separator de-ironing deironing become ceramic powder.Owing to adopted the batch bin storing and drying (when the raw material water content is lower than 8%, need not want dry), and adopt the raymond mill formula of catching up with to pulverize, to in the batch bin during dry materials, adopt the warm air that comes out in the short case of roller kiln brick output can effectively utilize the energy with dry hot gas as dry materials in the batch bin, having saved prior art need carry out the dry required energy to slurry, has avoided the generation of pollutent.
Here, enter the dry heat tracheae, be provided with downward aeroscopic plate at the place, air outlet of dry heat tracheae in order to prevent material.
Be provided with dry heat tracheae more than two or two at batch bin, the dry heat tracheae is communicated with by connecting leg, and many dry heat tracheaes are set, and can promote the rate of drying of material.
In order to make the material that enters in the batch bin can obtain sufficient drying in regular turn, the opening for feed of batch bin is positioned at the side above the batch bin.Owing to when material comes out from batch bin bottom centre exit, be that the material at batch bin middle part goes out earlier in regular turn, be only the material on four limits then.During warehouse entry, material enters batch bin by the lateral opening for feed that is positioned at above the batch bin, the time, at first be four limits that enter batch bin, like this, material just can obtain sufficient drying in regular turn.
The present invention compared with the prior art because the present invention do not have the ceramic size production process, need not spray tower spraying drying operation, therefore, have that technology is simple, less energy consumption, less investment, a advantage that production cost is low.
