Abstract
Description
Technical Field
[0001] The utility model relates to the field of sand making machine devices, in particular to a sand making machine for machine-made sand production. Background Art
[0002] Hammer Crusher
[0003] Artificial sand refers to the process of crushing, shaping, screening and other processing of raw materials such as natural rocks, mine tailings, and construction waste through special sand-making equipment to produce sand and gravel products with particle sizes that meet certain standard requirements. The sand making machine used in the production of artificial sand is the core equipment to complete this process. Its main function is to crush the raw materials into sand particles of the required particle size and ensure that the particle shape and gradation of the sand particles meet the quality requirements of building materials such as concrete, mortar, and road base. Among them, the hammer sand making machine uses a high-speed rotating hammer to strike, shear, and grind the material to achieve crushing. The hammer sand making machine is suitable for soft and medium-hard materials, with a simple structure and easy maintenance.
[0004] The existing sand making machines for artificial sand production fix two groups of impact plates arranged along the internal inclination angle of the sand making machine in its inner cavity by connecting them with multiple groups of plug rods, connecting rods and nuts, so that the connection of the impact plates is more stable. However, in actual production, due to the influence of factors such as material processing accuracy, assembly process, thermal expansion and contraction of components, tiny gaps may still appear between the inclined impact plates and the inner wall of the shell. Although these gaps are small, they are enough to allow fine materials to take advantage of the opportunity to enter, becoming a hidden danger to the operation of the equipment. Once they are stuck in the tiny gap between the inclined impact plates and the inner wall of the shell, it will not only increase additional wear, but may also cause local stress concentration and accelerate the loss of key components. Long-term accumulation may cause equipment performance to decline, shorten equipment service life and increase maintenance costs.
[0005] Therefore, it is necessary to provide a new sand making machine for machine-made sand production to solve the above-mentioned technical problems. Utility Model Content
