Description
本創作係有關一種磨輪結構改良，特別是指一種可增加使用壽命的磨輪結構改良。This creation relates to the improvement of a grinding wheel structure, in particular to the improvement of the grinding wheel structure which can increase the service life.
在建築營造業之中，常用且必須的材料之中，砂粒、碎石為最基本的原料，傳統的砂粒主要分為天然或加工兩種方式取得，除了最基本至河川溪谷中之天然開採外，另外一種加工取得則將取得之大顆粒的石頭、石塊擊碎，取得顆粒較小的碎石，再將其作進一步的震碎或磨碎成為細砂，由於砂粒的使用量較大，在一些海島型的國家中，例如台灣、日本等，普遍缺乏，因此在目前的市場中，砂粒的單價明顯高於碎石。為增加獲利，提高經濟利益，即不斷有人開發各種製砂機，以將碎石加工使之粉碎成為單價較高的砂粒，再予出售。Among the commonly used and necessary materials in the construction industry, sand and gravel are the most basic raw materials. Traditional sand grains are mainly obtained in natural or processed ways, except for the natural mining in the river valley. In another process, the large particles of stones and stones obtained are crushed to obtain smaller gravel, which is further shredded or ground into fine sand. Due to the large amount of sand used, In some island-type countries, such as Taiwan and Japan, there is a general lack, so in the current market, the unit price of sand is significantly higher than that of gravel. In order to increase profits and increase economic benefits, various sand-making machines have been developed to crush the crushed stone into high-priced sand and sell it.
而製砂機又名衝擊式破碎機，適用於軟或中硬物料的破碎、整形，製砂機廣泛應用於各種礦石、水泥、耐火材料、鋁凡土熟料、玻璃原料、機製建築砂、石料以及各種冶金礦渣的生產加工。該製砂機主要將物料(例如石塊)由機器上部垂直落入高速旋轉的磨輪內，在高速離心力的作用下，而另一傘流中的高速磨輪組成部分破碎的材料生產碰撞，每個碰撞材料，將在磨輪和機殼之間形成料層(例如磨碎之細砂)；其中，主要利用該些磨輪之 轉動對物料產生壓碎動作，以達到粉碎之目的，該磨輪表面常因磨損而形成耗材。The sand making machine, also known as impact crusher, is suitable for the crushing and shaping of soft or medium-hard materials. The sand making machine is widely used in various ores, cement, refractory materials, aluminum soil clinker, glass raw materials, mechanism construction sand, Production and processing of stone and various metallurgical slag. The sand making machine mainly divides materials (such as stones) from the upper part of the machine into the grinding wheel of high-speed rotation vertically, under the action of high-speed centrifugal force, and the high-speed grinding wheel of another umbrella flow forms part of the broken material to produce collision, each Collision material, which will form a layer between the grinding wheel and the casing (for example, ground fine sand); among them, mainly use the grinding wheel The rotation produces a crushing action on the material to achieve the purpose of pulverization, and the surface of the grinding wheel often forms a consumable due to wear.

The outer ring layer and the inner ring layer are integrally formed, so that the outer ring layer is thicker to achieve a better wear layer, which not only reduces the cost, but also increases the wear resistance and increases the use time period, and the improvement has the SCM49 steel. The surface is repaired, but the thickness of the weld repair is limited, the use conditions are poor, the cost is high, and the weld repair causes high pollution, which is not in line with the environmental protection requirements, and the assembly of the inner ring layer and the outer ring layer can be increased by the microstructure. To make the two close together and not easy to separate.
