With the increase of energy consumption, the environmental pressure is also increasing. In this trend, the crusher industry is more favored and more resources are utilized. When it is used in different functions, the crushers used are classified differently and have their own characteristics, but they are all developing towards automation, integration and according to the market demand. Next, we will analyze them respectively.
1、 Comparison between impact crusher and hammer crusher:
1. When the water content material is too large:
The impact crusher does not need to be equipped with a bottom sieve plate. The feeding chute and the impact plate can be equipped with a heating device to prevent the binding of materials.
The hammer crusher must be equipped with a bottom sieve plate, which can not be heated to prevent the material from sticking, thus increasing the possibility of blocking.
2. The impact crusher can adjust the discharge particle size by adjusting the rotor speed, adjusting the gap between the impact plate and the grinding chamber, etc., and the hydraulic control system can easily adjust the gap through the local operation button or the transportation control system.
The hammer crusher can only adjust the discharging granularity by changing the bottom sieve plate.
2、 Characteristics
Counterattack crusher
1. The discharge particle size is uniform, the discharge is cube shape, and the content of fine powder and dust is low, which is especially suitable for the operation of vertical mill; the motor power is low, so the power consumption is low, the operation cost is low, and the investment cost is low
2. The single stage impact crusher uses the impact kinetic energy to break the material along the joint layer, and the material is in a uniform cubic shape. After entering the crushing cavity between the impact plate and the rotor, the bulk material obtains kinetic energy by the rotation of the rotor part, and repeatedly impacts between the impact plate and the rotor, and is broken step by step through the first stage impact cavity, the second stage impact cavity and the bottom grinding cavity, respectively, to achieve the required discharge particle size.
3. The driving system adopts the mode of motor + mechanical coupling + V-belt + crusher, which can effectively improve the starting performance of the motor and make the motor start smoothly. The belt drive mode can play the function of double overload protection. The motor power required by the drive system is low, which greatly reduces the operation cost.
4. The multi-stage impact chamber of the impact crusher has large crushing space and is suitable for the crushing of large materials. The angle of the impact plate can be adjusted to ensure that the material is at a proper angle during repeated impact between the impact plate and the rotor, which can effectively improve the crushing efficiency. The energy consumption in the process of crushing can be effectively reduced by the step by step counterattack.
5. The plate hammer is firmly fixed on the rotor, so the starting torque of the crusher is small, the dynamic balance performance of the rotor is easy to control, the dynamic disturbance force in the operation process is small, and the starting is stable.
The monitoring system can monitor the operation of the crusher at any time, and the monitoring signal can be interlocked with the main control system to ensure the safe and reliable operation of the machine.
6. The hydraulic opening device is used for the opening and closing of the casing, which can effectively reduce the maintenance labor intensity, improve the maintenance work efficiency and shorten the maintenance work time.
Hammer crusher
1. Mobile hammer crusher. The whole machine covers the double crushing links of coarse crushing and medium crushing. It can form a three in one high-efficiency mobile heavy hammer crusher, or a four in one high-efficiency mobile crusher, which is equivalent to a complete crushing production line. It has strong environmental adaptability, strong operation ability, smaller occupied area and space, and more convenient production.
2. Ring hammer crusher. There is no sieve plate at the discharge port, so there will be no blockage in the production process. Its crushing device has a rotor with a ring hammer, and its structural design is closely linked, which has a significant crushing effect.
3. Heavy hammer crusher. The materials used include limestone, dolomite, bluestone, coal Xuan stone, etc. the hardness of the materials is not more than 200MPa, and it can also be used to treat and process small strength soft iron ore and wear-resistant materials, mainly used in the fine crushing production line.
There are many kinds of crushers, but the above is a simple list of several. There are many small models under each large type, and the technical parameters of each type are different, so which one needs to be selected according to the size and wet hardness of the operation materials, so as to better improve the crushing efficiency. |
