The impact crusher used in mines is widely used in the construction of building materials, roads, bridges, etc , with the advantages of large crushing strength and high efficiency. However, in use, frequency converters are often used to reduce equipment energy consumption. When selecting frequency converters, attention should be paid to the large load impact of impact crushers, and the gear of frequency converters used in crushers should be adjusted higher.
After the frequency conversion transformation of the impact crusher, the efficiency of the equipment will be improved a lot. Let's explain some advantages of the frequency converter to help the crushing equipment?
1. Reduce energy consumption as much as possible within the load range of the crusher.
Usually, the frequency converter used has the functions of controllable torque vector and adaptive load torque. When the load of the crusher increases, the frequency converter can automatically increase the frequency and current, which ensures that the energy consumption of the counterattack is low under the load state. However, when the load is reduced, the frequency and voltage will be reduced.
2. It protects the motor of impact crusher used in mines.
When the load is also increased, the function of the frequency converter will greatly reduce the copper loss, iron loss and the loss of accessories of the motor, so as to improve the actual efficiency of the crusher with the motor as much as possible. At the same time, it will also reduce the heating degree of the motor and prolong the service life, so as to achieve the purpose of saving electricity.
3. The braking unit can interlock and control all systems of the crusher for standby.
For the inertia load of the crusher, we need to load the braking unit or feedback unit according to the site conditions, retain the original system on the basis of the frequency conversion control system, and interlock the control for standby, which reduces the processing time of the regenerative energy generated by the braking of the speed regulating device to a certain extent.
4. Improve the working efficiency of crusher.
Users can adjust the appropriate speed according to the material and the required discharge particle size. The output torque of the frequency conversion control crusher changes with the change of load, which effectively improves the work efficiency.
It can be seen that the crusher system controlled by frequency converter plays a significant role in saving energy, improving crushing efficiency and reducing production costs of enterprises. The frequency conversion transformation of impact crusher is undoubtedly a good choice for enterprises and users. Especially in recent years, under the background of energy conservation and environmental protection, the quality and reputation of the frequency conversion transformation crusher equipment of SMMVIK Machinery are more and more widely used in the market.
