Horizontal hammer type
The horizontal hammer sand making machine is mainly PX high-efficiency fine crusher (split hammer head structure) and (integral hammer head structure). The hammer head and hammer handle of the high-efficiency fine crusher are split structure, and the hammer head is made of high-strength wear-resistant material, and the life of the hammer head is long. The hammer head can be easily replaced
The hammer head is a sand making machine with an integral structure, and the hammer head is directly connected to the rotor through the rod. With this structure, the hammer head will produce a large force after the crushing process, and it is easy to wear the hammer head. However, this mechanical structure is simple.
Vertical shaft hammer type
The one shown is the vertical shaft hammer sand making machine, which can also be used as a crusher
The vertical shaft hammer sand making machine is mainly used for the second or third stage of fine crushing, which can handle various coarse, medium and fine materials (granite, limestone, concrete, etc.) with a side length of no more than 500mm and a compressive strength of no more than 350MPa, and is widely used in hydropower, highways, artificial sand and gravel industries.
Third generation
The third generation of sand and gravel dual-purpose sand making machine is also called high-efficiency fine crusher, impact sand making machine. The comprehensive performance of the machine is better than that of impact sand making machine, rod mill sand making machine, true impact sand making machine, and cone crushing
machine and soft hammer crusher. The equipment is suitable for mechanism artificial stone making, sand making field, high-grade highway, railway, water conservancy, construction, cement, refractory, metallurgy, glass sand and other industries.
When working, driven by the motor, the rotor rotates at high speed, and the material enters the first crushing chamber and the plate hammer of the rotor hits and crushes, and then enters the second crushing cavity for crushing. In 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-on-stone shaping between each plate hammer and in the crushing cavity is completed. Finally, it is discharged from the discharge port.
Sixth generation
Advanced features of the sixth generation sand making machine:
(1) On the basis of the third generation of sand making machine, the counterweight wheel is added, which saves electric energy and increases kinetic energy. The production efficiency has been greatly improved. The impact plate adjustment device is added, so that the adjustment of the fineness of the discharge is more convenient and fast, and the case can be adjusted without opening the casing, and two impact plate adjustment devices are designed to save the trouble of using the crane.
(2) The old-fashioned third-generation sand making machine only has an observation door at the rear. The new sixth-generation sand making machine also has a maintenance observation door on its side. This is more conducive to maintenance and observation of the operation of the equipment.
(3) The discharging counterattack plate is added on both sides of the grate adjusting device, which has the function of multiple crushing materials, so that the materials are grinding, squeezing and colliding in the crushing cavity, so that the sand output rate is higher, and with the shaping effect, the sand particle type is better and more uniform, and the discharging particle size of the sand can be adjusted more conveniently. The design is more user-friendly.
The investment of the sixth-generation sand making machine is 35%-50% lower than that of traditional process equipment of the same scale, and the output efficiency is 35%-50% higher than that of traditional process equipment of the same scale (taking limestone as an example: the particle size of the primary product ≤5mm accounts for more than 90%, and the particle size of the primary finished product of river pebble ≤ 5mm accounts for more than 80%)). Long-term maintenance costs
Vertical shaft impact type
According to the structure of the rotor, the vertical shaft impact sand making machine is divided into: open rotor structure and closed rotor structure.
The closed rotor structure is a cage layout of the rotor, and the material falls into the closed rotor from the top
Roller
In the field of sand making with small production capacity, roller crusher is often used as a sand making machine, and there are also some applications. But the roller sand making machine is in long-term use
The reliability in the process is poor, the failure rate of the equipment is high, and the repair and maintenance are more difficult
Therefore, for materials with a certain hardness and high abrasiveness, try to avoid using roller sand making machines
As the first new type of sand making machine to be started hydraulically, it saves 50% of electricity compared with traditional sand making machines in terms of energy saving. It can make all kinds of rocks, sand and gravel, river pebbles into construction sand with various particle sizes, with uniform sand particle size and high compressive strength, which is far more in line with construction requirements than natural sand and sand produced by ordinary hammer sand blasting machine, and can improve the quality of construction
