Application of FGI FD300 High Performance Low Voltage Frequency Inverter in sand making machine
1.Introduction to sand making machine
Sand making machine, also known as impact crusher, is a kind of equipment that breaks large pieces of stone into sand and stone aggregates that meet the needs of construction, roads, water conservancy and other industries. Its working principle is based on the impact between the materials, through the high-speed rotating rotor will throw the material, impact the counter plate or other materials, to achieve crushing and shaping. This process has high requirements for the stability and control accuracy of the equipment. The FD300 series of high performance low voltage frequency converters from FGI, with its advanced vector control technology, demonstrate excellent performance and reliability in sand making machine applications.
2.Advantages of FD300 low voltage frequency inverter applications
(1) Energy saving and dynamic speed regulation
Sand making machine has a wide range of processing capacity (such as 10-520t/h), and needs to adapt to the crushing needs of different materials (such as granite, basalt and other high hardness materials). The FD300 frequency inverter can dynamically match the load requirements by adjusting the motor speed. For example, reducing the speed at low load to reduce energy consumption, or increasing the speed to enhance the crushing effect when dealing with high hardness materials, thereby reducing the comprehensive energy consumption by 20%-30%.
The soft start function of the inverter can avoid the high current impact when the motor is started directly, and extend the life of the equipment, especially for the condition of frequent start and stop.
(2) Improve discharge quality and stability
The sand making machine has high requirements for the uniformity of the discharge particle size (such as the required particle size <5mm). By accurately controlling the motor speed, FD300 frequency inverter can stabilize the impeller speed (such as the impeller speed range of 800-3000r/min) 4, to ensure that the impact force and residence time of the material in the crushing chamber are consistent, thereby reducing particle size fluctuations and improving the cube proportion and bulk density of the finished sand.
Better adaptability to high humidity (such as 8% moisture content) or viscous materials, by adjusting the speed to avoid clogging, to ensure continuous production.
When the sand making machine is operated in a highly abrasive environment (such as steel slag and construction waste crushing), the equipment is seriously worn. The FD300 frequency inverter reduces mechanical shock by smoothly adjusting the load, reducing the wear rate of key components such as impels and bearings, while its built-in overload protection and fault diagnosis function prevents the motor from overheating or overcurrent damage.
Combined with an automated control system in the sand production line, such as PLC control, the inverter enables remote monitoring and parameter optimization, reducing the frequency of manual intervention and maintenance.
(4) Adapt to diversified production needs
The sand making machine needs to flexibly respond to the sand specification requirements of different engineering scenarios (such as highways, high-rise buildings, and high purity production of quartz sand). The FD300 frequency inverter supports multi-speed setting and fast response for easy switching of production modes. For example, in the production of glass quartz sand, iron pollution is reduced by reducing the rotational speed to ensure product purity.
In the recycling treatment of construction waste, the frequency converter can dynamically adjust the crushing strength according to the hardness of the material to improve the utilization rate of resources.
3. Sum up
The application of FGI FD300 frequency inverter in sand making machine has comprehensively optimized the efficiency and reliability of sand making production line through dynamic speed regulation, energy saving control, stability improvement and intelligent management. Its technical advantages are especially suitable for high-hardness material crushing, environmental protection projects (such as construction waste treatment) and high-purity sand production scenarios. The specific parameter configuration needs to be further designed according to the sand making model number (such as PXJ series or PCL series) and actual working conditions.
