The new sand making machine (vertical shaft impact crusher) is suitable for the crushing of soft or medium hard and extremely hard ore materials with a hardness not higher than 320Pa. The sand making machine is widely used in large, smelting, building materials, highway, railway, water conservancy and Chemical industry and many other sectors.
Horizontal hammer The horizontal hammer type sand making machine is mainly a PX high-efficiency fine crusher (separate hammer head structure) and (integral hammer head structure). The hammer head and the hammer handle of the high-efficiency fine crusher are split structures. The hammer head is made of high-strength and wear-resistant material, and the life of the hammer head is longer. The replacement of the hammer head is more convenient. The hammer head is a sand making machine with an integrated structure, and the hammer head is directly connected to the rotor through a rod. With this structure, the hammer head will generate a large force after the crushing process, and it is easy to wear the hammer head. But this mechanical structure is simple.
Vertical shaft hammer The right picture shows the vertical shaft hammer sand making machine, which can also be used as a crusher. Vertical shaft hammer type sand making machine is mainly used for the second or third stage fine crushing. It can process all kinds of coarse, medium and fine materials (granite, limestone, concrete, etc.) with side length not exceeding 500mm and compressive strength not exceeding 350MPa Widely used in hydropower, highway, artificial sand and stone industries.
Third Generation The third-generation dual-purpose sand making machine is also called high-efficiency fine crusher and counter-type sand making machine. The overall performance of this machine is better than impact sand maker, rod mill sand maker, Zhentong impact sand maker, as well as cone crusher and soft hammer crusher. This equipment is suitable for mechanical artificial stone, sand making field, high-grade highway, railway, water conservancy, construction, cement, refractory, metallurgy, glass sand and other industries. During work, driven by the motor, the rotor rotates at a high speed, and the material enters the first crushing cavity and is crushed by the hammer of the rotor, and then enters the second crushing cavity for crushing. During the crushing process, not only the impact crushing between the material and the plate hammer and the lining plate is formed, but also the stone-shaping of the plate hammer and the crushing cavity is completed. Finally discharged from the discharge port.
Sixth generation Advanced features of the sixth generation sand making machine: 增加 Added counterweight wheels on the basis of the third-generation sand making machine, which saved electricity and increased kinetic energy. The production efficiency has been greatly improved. The impact plate adjustment device has been added to make the adjustment of the discharge fineness even more. Convenient and fast, it can be adjusted without opening the casing, and a total of two impact plate adjustment devices are designed to save the trouble of using a crane. ⑵The old third-generation sand making machine only has an observation door at the rear. The new sixth-generation sand making machine also opened a maintenance observation door on its side. This is more conducive to maintenance and observation of the equipment’s operation. (3) The counterattack plates are added on both sides of the caster adjusting device. It has the function of multiple crushing materials, which enables the materials to be ground, squeezed, and collided in the crushing cavity to make the sand production rate higher. The sand particle type is better and more uniform. In addition, the sand particle size can be easily adjusted. The design is more user-friendly. The investment of the sixth-generation sand making machine is 35% -50% lower than the traditional technology equipment of the same scale, and the output efficiency is higher than 35% -50% of the traditional technology equipment of the same scale (Take limestone as an example: the size of the finished product ≤ 5mm accounts for more than 90%) , The particle size of the primary product of river pebble ≤ 5mm accounts for more than 80%).
Vertical shaft impact Vertical shaft impact sand making machine is divided into open rotor structure and closed rotor structure according to the structure of the rotor. Closed rotor structure, the rotor is arranged into a cage, and the material falls from the top into the closed rotor
Roller In the field of sand production with small capacity, roller crushers are often used as sand making machines, and there are also some applications. However, the roller sand making machine has poor reliability during long-term use, high failure rate of equipment, and difficult repair and maintenance. Therefore, for materials with a certain hardness and high abrasiveness, try to avoid using a roller sand making machine. As the first new type of sand making machine with hydraulic start, it can save 50% of electricity compared to traditional sand making machines. It can make all kinds of rock, sand stone, river pebble and construction sand with various particle sizes. The uniformity of the sand particles and the high compressive strength are much better than the sand produced by natural sand and ordinary hammer sander. Requirements to better improve building quality
