Horizontal hammer sand making machine
Horizontal hammer sand makers are mainly PX high-efficiency fine crusher (split hammer structure) and sand beater (integral hammer structure).
The hammer head and the hammer handle of the high-efficiency fine crusher adopt a split structure, and the hammer head is made of high-strength wear-resistant materials, so that the service life of the hammer head is long. The replacement of the hammer is more convenient. There is a sieve plate structure at the bottom, which can realize effective grinding and improve sand making efficiency. The hammer head of the sander is an integral structure, and the hammer head is directly connected to the rotor through a rod. Because of this structure, the hammer will produce a large force after being broken, so the hardness of the hammer material is low, so the wear resistance of the hammer is weak. Courage sander is simple in structure and cheap, and it is a choice for small workplaces.
2. Vertical shaft impact sand making machine
According to the rotor structure, vertical shaft impact sand making machine can be divided into open rotor structure and closed rotor structure. The closed rotor structure is the cage layout of the rotor, and the material falls into the closed rotor from the top and is thrown out at high speed. Open rotor structure means that the rotor is an open structure, and materials fall into the rotor and are knocked out by a hammer.
3. Roller sand making machine
In the field of small-capacity sand making, there are also some applications using roller crusher as sand making machine. However, roller sand makers have been used for a long time.
In this process, the reliability is poor, the equipment failure rate is high and the maintenance is difficult. Therefore, for materials with certain hardness and high abrasiveness, try to avoid using roller fine crusher.
4. Vertical shaft hammer sand making machine
The picture above shows a vertical shaft hammer crusher, which can also be used as a sand making machine. This equipment has no bottom sieve plate, so it won't be blocked. The hammer head has an integral structure and is connected with the rotor through a connecting rod.
5.VSI series sand making machine
As the first impact sand maker started by hydraulic pressure, VSI series sand makers save 50% energy compared with traditional sand makers. All kinds of rocks, sandstone and river pebbles can be made into building sand with various particle sizes. The sand has uniform particle size and high compressive strength, which is far more in line with building requirements than natural sand and sand produced by ordinary hammer sander, and can improve building quality. The equipment has the characteristics of reliable performance, reasonable design, convenient operation and high working efficiency. VSI sand making machine is the latest design achievement of German authoritative experts combined with China working conditions. This machine inherits the innovative crushing concept of impact sand making machine, applies advanced selective crushing and splitting crushing principles, directly applies enough kinetic energy to the material, and converts the kinetic energy into crushing energy needed to overcome the material through impact. The material basically fractures along its natural grain surface and cleavage surface, with good grain shape and low self-consumption, which is more in line with the requirements of architecture, high-grade highways and railways, water conservancy and hydropower projects for machine-made aggregates.
6. The new sixth generation sand making machine
The sixth generation sand making machine has the following advanced functions:
(1) On the basis of the third generation sand making machine, a balance wheel is added, which saves electric energy and increases kinetic energy. The production efficiency is greatly improved. The adjusting device of the impact plate is added, so that the fineness of discharging can be adjusted more conveniently and quickly without opening the shell. * * * Two impact plate adjusting devices are designed, which saves the trouble of using a crane. (2) The third generation sand maker only has an observation door at the back. The new sixth-generation sand maker also has a maintenance observation door on its side, which is more conducive to maintenance and observation of the operation of the equipment. (3) The discharging impact plates are added on both sides of the grate bar adjusting device, which has the function of multiple crushing materials, so that the materials can be ground, squeezed and collided in the crushing cavity, and the sand yield is higher, which has the shaping function, so that the shape of sand particles is better and more uniform, and the adjustment of sand particle size is more convenient ... The design is more humanized. The investment of the sixth generation sand making machine (www.xinzhishashebei.com) is 35%-50% lower than that of the traditional process equipment of the same scale, and the output efficiency is 35%-50% higher than that of the traditional process equipment of the same scale (take limestone as an example: more than 90% of the finished products have a particle size of ≤5mm, and more than 80% have a particle size of ≤5mm). Long-term operation and maintenance cost is 35%-50% lower than that of traditional process equipment of the same scale, and it is widely used in machine-made sandstone, cement, refractories, metallurgy and other industries.
