The grinding device includes a plurality of sealed material bowls. The sealed material bowl includes a bowl body, a crushing hammer and a bowl cover; the bowl body There is a sealing ring or gasket between the bowl body cover and the bowl body cover, which can ensure the close connection between the bowl body cover and the bowl body during the crushing process, and avoid material leakage during the crushing process;
将密封料钵的钵体盖设为中空，使得物料在钵体盖内能够被多个圆柱形的粉碎块粗粉碎，然后从钵体盖底部直径为3-8mm的开孔落入料钵本体内，再进一步的进入料钵本体内进行精细粉碎。由于物料逐步落入料钵本体内，同时料钵本体内的粉碎锤下端的密度大于上端的密度，使得粉碎锤能够稳定的对逐渐落入料钵本体内的物料进行粉碎，保证了粉碎细度与均匀度，同时相较于传统制样粉碎机，粉碎得到相同目数的物料所需的时间更少，提升了粉碎的效率，减少了电能的消耗；由于料钵本体内部呈弧形凹陷，使得物料能够集中在料钵本体的底部便于粉碎后进行物料的回收；同时钵体盖的高度小于料钵本体的高度，能够有效避免物料添加过多无法完全粉碎的问题；Set the pot cover of the sealed material bowl to be hollow, so that the material in the bowl cover can be roughly crushed by a number of cylindrical crushing blocks, and then fall into the bowl body from the opening of the bottom of the bowl cover with a diameter of 3-8mm Inside, it further enters the bowl body for fine crushing. Since the materials gradually fall into the bowl body, and the density of the crushing hammer at the lower end of the bowl body is greater than the density at the upper end, the crushing hammer can smash the materials gradually falling into the bowl body stably, ensuring the fineness of the crushing. And uniformity, and compared with the traditional sample crusher, it takes less time to crush the material of the same mesh, which improves the efficiency of crushing and reduces the power consumption; because the inside of the bowl body is arc-shaped, The materials can be concentrated at the bottom of the bowl body to facilitate the recovery of materials after crushing; at the same time, the height of the bowl body cover is smaller than the height of the bowl body, which can effectively avoid the problem of excessive addition of materials that cannot be completely crushed;
通过设置3-8mm的开孔，使该制样粉碎机适用于大部分应用制样粉碎机粉碎的物料，利于初步粉碎后的物料快速落入料钵本体内；By setting the opening of 3-8mm, the sample preparation crusher is suitable for most materials crushed by the sample preparation crusher, which is beneficial for the preliminary crushed materials to quickly fall into the bowl body;
通过在机箱内部上设置发泡吸音板，能够减少制样粉碎机使用过程中产生的噪音，避免产生噪音污染。By arranging a foaming sound-absorbing board inside the cabinet, the noise generated during the use of the sample preparation grinder can be reduced and noise pollution can be avoided.
以上所述仅为本实用新型的实施例，并非因此限制本实用新型的专利范围，凡是利用本实用新型说明书及附图内容所作的等同变换，或直接或间接运用在相关的技术领域，均同理包括在本实用新型的专利保护范围内。The above descriptions are only examples of the utility model, and do not limit the scope of the utility model's patents. Any equivalent transformations made using the contents of the utility model description and drawings, or directly or indirectly applied to related technical fields, are the same. The principle is included in the scope of patent protection of this utility model.
