There are many shapes of Smooth Plate Hammer Blade currently used, but the most widely used is the plate-shaped rectangular hammer blade, because of its simple shape, easy manufacture, and good versatility.
The Smooth Plate Hammer Blade has two pin shafts, one of which is threaded on the pin shaft, and the four corners can be used alternately for work. Coating welding, surfacing welding tungsten carbide or welding a special wear-resistant alloy on the working side to prolong the service life, but the manufacturing cost is relatively high. Poor abrasion resistance. The annular hammer has only one pin hole, and the working angle is automatically changed during work, so the wear is uniform and the service life is long, but the structure is complicated. The composite steel rectangular hammer is a steel plate with high hardness on the two surfaces and good toughness in the interlayer provided by the rolling mill. It is simple to manufacture and low in cost.
Tests have shown that the appropriate length of the Smooth Plate Hammer Blade is conducive to increasing the kWh output, but if it is too long, the metal consumption will increase and the kWh output will decrease. According to the China Agricultural Mechanization Research Institute using 1.6mm, 3.0mm, 5.0mm, 6.25mm four thickness hammers for corn crushing test, it is concluded that the crushing effect of 1.6mm is 45% higher than that of 6.25mm hammer, and 25.4% higher than that of 5mm. The efficiency of crushing with a thin hammer is high, but the service life is relatively shortened. The thickness of the hammer used should vary depending on the crushing object and the size of the model.
