Abstract
The utility model provides an air flow mill for preparing ceramic spherical granular materials, which can reduce the material loss; it comprises a top cover and a ground bottom. One side of the grinding bottom facing the top cover is made into a stepped grinding chamber. The side wall of the mill bottom is provided with an air inlet which is communicated with the mill chamber, the top cover is provided with an air outlet, and the mill bottom is provided with the top cover. When the equipment is used, the material particles can be ground for a long time in the jet mill and cannot be carried out by the air flow, the loss of the material is reduced, and the sphericity of the material particles meets the use requirement.
Description
Technical field
The utility model belongs to the equipment for preparing ceramic material, is specifically related to a kind of airflow milling for preparing the ceramic spherical granular materials.
Background technology
The air-flow polishing has been widely used in the production of micron order ceramic powders at present, has been used for broken powder process industrial.Produce the capital equipment airflow milling of carbide ceramics microballoon with the air-flow polishing, its mill chamber is a straight barrel type, the broken powder process of ceramic material can only be used for and the grinding nodularization of material can not be used for, and in process of production, material can fly out from airflow milling, causes the loss of material.
Summary of the invention
The purpose of this utility model is to provide a kind of can reduce loss of material, make spheric granules satisfy the airflow milling of the preparation ceramic spherical granular materials of instructions for use.
A kind of airflow milling for preparing the ceramic spherical granular materials, comprise the top cover and the mill end, be provided with top cover at mill at the end, the side of the mill end towards top cover is made into step mill chamber, sidewall at the mill end has the air inlet that communicates with the chamber of mill, has the gas outlet that communicates with the chamber of mill on the top cover.
Effect of the present utility model is: when using this equipment, owing to improved the structure of airflow milling, change the straight barrel type chamber of mill into step mill chamber, make material particles can in airflow milling, stand to grind for a long time and can not taken out of by air-flow, reduced the loss of material, and made the sphericity of material particles satisfy instructions for use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of the utility model mill chamber.
Among the figure: 1. gas outlet, 2. top cover, 3. mill chamber, 4. air inlet, 5. the mill end, 6. screw
The specific embodiment
Below in conjunction with embodiment technical scheme of the present invention is further elaborated.
As shown in Figure 1, 2, a kind of airflow milling for preparing the ceramic spherical granular materials, comprise the top cover 2 and the mill end 5, wherein top cover 2 and the mill ends 5 usefulness stainless steel are made, be provided with top cover 2 at mill at the end 5, the side of the mill end 5 towards top cover is made into step mill chamber 3, in mill chamber 3, be lined with vacuum rubber, sidewall at the mill end 5 has and grinds chamber 3 air inlet 4 that communicates, have on the top cover 2 and grind the gas outlet 1 that chamber 3 communicates, be provided with screw 6 at the top cover 2 and the relevant position at the mill end 5, can be top cover 2 is fixing with the mill end 5 by screw 6 usefulness screws.
With preparation high density carbonization boron spheric granules is example, when using airflow milling, is 100～120 μ m ceramic materials mill chambers 3 of packing into granularity, covers top cover 2, with screw that top cover 2 is fixing with the mill end 5.During grinding, air-flow enters from air inlet 4, and 1 flows out from the gas outlet, grinding pressure 0.35Mpa, and milling time 2 hours is prepared granularity and is reached 2.3g/cm in 50～90 μ m, density
3More than, sphericity reaches the boron carbide spherical granular material more than 0.95.
