【摘要】：近10年来,为适应市场需求,锤片式微粉碎机的技术创新取得了显著进步。主要体现在以下方面:(1)粉碎筛片的振动技术。该项国际专利技术使锤片粉碎机的锤筛间隙动态变化,既破坏了传统粉碎机存在的物料环流层,同时增加了对物料穿过筛孔的推动力,显著提高了物料过筛速度和粉碎产量,特别是提高了高水分物料、高油脂物料、高黏性物料的过筛率,降低了无效能耗;(2)在粉碎室内增加定锤的专利技术。该专利技术大大增加了物料在粉碎室内被撞击的次数和剪切式粉碎,增加了粉碎的概率,提高了粉碎的效率;(3)在粉碎机主轴上增加轴向通风风叶的专利技术。增加了对筛片的横向清理效果和物料横向运动,既可提高过筛率,又增加了物料被打击的机会;(4)锤筛间隙在一定范围的无级调整专利技术。该技术使操作者可根据粉碎粒度要求和物料的特性以及生产状态随时调整到最佳锤筛间隙;(5)锤片打击端面开刃的专利技术。该技术增加了对物料劈裂作用和将物料推向两侧以获得更多的打击机会;(6)波纹形压筛机构。该种机构与筛片接触的表面为波纹性状,这样可以让更多的筛孔不被压筛机构封堵,提供更多的有效筛孔面积。上述这些专利技术的综合应用,使我国的新型锤片微粉碎机产品具有很高的生产效率,适应的原料种类更广,更加节能。
[Abstract]:In recent 10 years, in order to meet the market demand, the technical innovation of hammer micro crusher has made remarkable progress. Mainly reflected in the following aspects: (1) the vibration technology of comminuted screen. The international patented technology makes the hammer screen clearance of the hammer piece grinder change dynamically, which not only destroys the material annular layer existing in the traditional grinder, but also increases the driving force of the material through the screen hole, and significantly increases the screening speed and crushing output of the material. In particular, the screening rate of high moisture material, high fat material and high viscosity material is improved, and the invalid energy consumption is reduced. (2) the patented technology of adding fixed hammer in crushing chamber. The patented technology greatly increases the number of hits and shear crushing of the material in the crushing chamber, increases the probability of crushing, and improves the crushing efficiency. (3) the patented technology of adding axial ventilation blade to the main shaft of the grinder. The transverse cleaning effect of the screen and the transverse movement of the material are increased, which can not only increase the screening rate, but also increase the chance of the material being hit. (4) the patent technology of stepless adjustment of the hammer screen clearance in a certain range. This technology enables the operator to adjust to the best hammer screen clearance at any time according to the requirements of crushing particle size, the characteristics of the material and the production state. (5) the patented technology of hammer blade hitting end face. This technology increases the split effect on the material and pushes the material to both sides to obtain more hitting opportunities. (6) Bellows press screen mechanism. The surface of the contact between the mechanism and the screen is wavy, so that more screen holes can not be blocked by the pressure screen mechanism, and more effective screen hole area can be provided. With the comprehensive application of these patented technologies, the new hammer microcrusher products in China have high production efficiency, a wider range of suitable raw materials and more energy saving.
