Description

Technical Field

[0001] The utility model relates to the technical field of crushed bricks, in particular to a crusher used for making bricks from construction waste. Background Art

[0002] In 1942, German Andreson invented the AP series crusher, which is similar to the structure of modern crusher, based on the structural characteristics and working principle of the hammer crusher of the squirrel cage crusher. Thanks to the high production efficiency of this impact crusher, it can handle relatively large materials, and it is relatively simple in form and structure and easy to maintain. Therefore, this crusher has been rapidly developed. With the continuous improvement of crushing and screening crushing theory and the further development of technology, various high-performance crushers have emerged in an endless stream. With the continuous development of international science and technology, large-scale crushing and screening equipment has been developed very well. At present, the crusher completes the crushing by the high-speed rotation of the cutter on the hammer body and the mutual cooperation of the extrusion plate to hit the object. Some of them also adapt to the different crushing degrees of building waste brick making by moving the manual rotating screw inward and driving the extrusion plate position to be adjustable. However, this type of crusher has the following problems: the extrusion plate position is single, and it is impossible to realize the stable and automatic adjustment of the extrusion plate from multiple angles, which leads to low crushing efficiency of building waste brick making. The structure of the crushing cutter body is specific and not easy to replace, resulting in limited crushing degree and unsatisfactory effect. For this reason, we propose a crusher for building waste brick making. Utility Model Content
