Non-metallic mineral crushing is a complex process that consists of three main stages: primary crushing, secondary crushing, and screening. Each stage has its own core objectives and the equipment used plays a specific role. In the primary crushing stage, the main goal is to reduce large chunks of ore into smaller pieces. The PEW jaw crusher is often the first choice in this stage. It acts as the initial gatekeeper, breaking down the raw materials into a size suitable for further processing.
The secondary crushing stage is where the cone crusher comes in. Its task is to further reduce the size of the ore particles from the primary crushing. The vibrating screen, on the other hand, is responsible for the screening stage. It separates the crushed materials into different sizes, ensuring that the final product meets the required specifications. The synergy between these three types of equipment is crucial for achieving high - efficiency and high - quality crushing.
The PEW jaw crusher brings several significant technical advantages compared to traditional models. One of the most notable features is its V - shaped crushing chamber. This unique design allows for a more efficient crushing process. The V - shaped chamber can increase the crushing ratio by up to 30%. This means that it can break the ore into smaller pieces with fewer crushing cycles, which not only saves energy but also improves the overall production efficiency.
Moreover, the PEW jaw crusher has a relatively low energy consumption. With the increasing emphasis on sustainable development, energy - saving equipment is becoming more and more popular. The PEW jaw crusher can achieve high - quality crushing results while consuming less electricity, making it a cost - effective choice for mining enterprises.
Different non - metallic ores, such as limestone and granite, have different physical and chemical properties. These differences have a significant impact on the parameter settings of the crushing equipment. Limestone is a relatively soft ore, with a Mohs hardness of about 3. It is easier to crush and has a lower requirement for the crushing force. Therefore, when using the PEW jaw crusher and other equipment to crush limestone, the equipment can be set to a relatively high - speed operation mode to improve the production efficiency.
On the contrary, granite is a hard ore with a Mohs hardness of about 6 - 7. It requires a higher crushing force. When crushing granite, the parameter settings of the equipment need to be adjusted accordingly. For example, the crushing chamber can be adjusted to a smaller opening to increase the crushing force, and the speed of the equipment can be appropriately reduced to ensure the crushing effect.
In the non - metallic mineral crushing process, several common problems may occur, such as over - crushing, poor discharge, and insufficient production capacity. Over - crushing can lead to a waste of energy and resources, while poor discharge can cause blockages in the equipment, affecting the normal operation of the production line. Insufficient production capacity, on the other hand, directly restricts the economic benefits of the enterprise.
To diagnose these problems, it is necessary to carefully observe the operation status of the equipment, including the particle size of the discharge, the sound of the equipment, and the current of the motor. For over - crushing, adjusting the crushing ratio and the speed of the equipment can be effective solutions. For poor discharge, checking the discharge port for blockages and adjusting the opening size of the discharge port can solve the problem. For insufficient production capacity, optimizing the parameter settings of the equipment and improving the cooperation between different equipment can be considered.
Real - world project on - site commissioning is an important step to ensure the normal operation of the crushing equipment. Through on - site commissioning, the equipment can be adjusted to the best working state according to the actual situation of the mine. For example, in a limestone crushing project, after on - site commissioning, the production capacity of the entire crushing line increased by 20%, and the energy consumption per unit product decreased by 15%.
These data not only demonstrate the effectiveness of on - site commissioning but also enhance the credibility and practicality of the entire non - metallic mineral crushing process. By learning from these real - world cases, mining enterprises can better select and operate their crushing equipment.
