In the sand and gravel production line, the use of crushers simplifies the sand-making process for large pieces, while the sand-making machine plays a role in further shaping the crushed material. Through the analysis of sand-making machine production, certain conditions necessary for high-performance sand-making have been identified. Only by meeting these conditions can the production of sand-making machines maintain high efficiency and stability. Below are the factors required for the efficient production of sand-making machines:
In the setup of the feed device for sand-making machines, a relatively unified process specification must be adopted to minimize particle size discrepancies during feeding. Under such conditions, once the sand-making machine is operational, it will run at a very high speed, and with the increase in inertial force, its smoothness will be exceptionally high.
In the selection process of the crushing cavity for sand-making machines, we find that it's not necessarily the elongated cavity that allows for longer material retention that optimizes the sand-making operation of the machine. This requires determining the time of the most time-consuming steps in the entire process. Generally, for medium to low yields, we opt for a 2-3 cavity design, while for high yields, we choose a simplified design with continuous cavities, even down to a single cavity.
3. In the design of the sand-making machine cavity, the simplified structure of a single cavity requires that we can control the particle size to perfection. Not all particle size control theories can be applied to the working cavity design of this type of sand-making machine. After comparing the manufacturing processes, we found that crushers with U-shaped cavities are particularly suitable for this production requirement.
4. The new high-performance sand-making machine production line requires particle shape control. We have adopted an incentive-type computer control system for particle shape control, which offers the advantage of high autonomy and automation. If the particle shape does not meet the requirements, it is impossible to produce fine crushing cavities. When adjustments to the cavity-type mechanism are needed, the use of fully automatic sensor installation greatly saves labor costs.
