[0040] Next, the working principle of the circulating pair of roller crushing machine set in the embodiment of the application is described.
[0041] The artificial hopper is used to receive large pieces of material to be processed, serving as the starting point of the entire system, providing a stable source of material for subsequent processes. The vibrating feeder is located below the artificial hopper and receives material through a soft connection, responsible for uniformly feeding the material into the next level of equipment, the roller crusher, for crushing operations. The vibrating feeder can ensure that the material is fed into the crusher at a constant speed and level, avoiding problems such as equipment overload or low efficiency caused by uneven feeding. The roller crusher is one of the core components of the system, which receives material from the vibrating feeder and precisely crushes it to achieve the predetermined particle size range. The roller crusher uses two oppositely rotating rollers to apply high compression and shear forces, effectively crushing large pieces of material into smaller particles. The vibrating screen is located below the roller crusher and is responsible for screening the crushed material. It can distinguish between small particle finished products that meet the standard (discharged through the lower discharge port) and large particles that need further crushing (sent to the fluidization hopper through the upper discharge port), ensuring that all output products meet the specified specifications. The fluidization hopper is located on one side of the vibrating screen and receives large particle materials that still need to be crushed again. Through the connection between the fluidization hopper and the vacuum feeder, these materials can be smoothly returned to the vibrating feeder to start the crushing process again until the required particle size is reached. The vacuum feeder is located above the vibrating feeder and is connected to its second inlet through a soft connection, while its inlet is connected to the outlet of the fluidization hopper, forming a closed-loop system. This means that materials that do not meet the required particle size after preliminary screening or processing can be returned to the vibrating feeder from the fluidization hopper to re-enter the crushing process, achieving recycling of materials and ensuring the quality consistency of the final product. Through the clever and close cooperation between the above components, this circulating roller crusher set not only simplifies the production process and reduces the complexity of operation, but also greatly improves resource utilization and product qualification rate. In addition, the soft connection between the links helps to absorb vibration, reduce noise pollution, and facilitate maintenance work.
[0042] In summary, the present application introduces a circulating crushing mechanism, which allows substandard materials to be re-fed into the crushing chamber for secondary or even multiple processing until the specified quality requirements are met, thereby significantly improving the purity and consistency of the product. At the same time, the present application fully considers the optimization of the overall floor area, integrates efficient screening functions, reduces the need for additional auxiliary equipment, reduces the degree of human intervention, and thus improves the efficiency of the entire production process. In this case, not only helps to improve the working environment and reduce the emission of dust and other pollutants, but also brings lower operating costs and higher economic benefits to users.
