This article discusses measures to reduce jaw plate wear in jaw crushers, crucial for mining production lines handling high-hardness materials. Traditionally, jaw plates are made of high manganese steel, leading to high costs and significant wear issues. Research by Heavy Industry has focused on reducing energy consumption and extending jaw plate life. By applying dissipative structure theory and other principles, a critical threshold for damage energy release rate was established. Mathematical models for jaw crushers and motor power were developed and validated through experiments. Stress analysis and optimization using fuzzy stochastic theory and Ansys software led to an improved jaw plate design that reduces stress concentration, extends service life, saved manufacturing materials, and lowered the energy consumption during material crushing. Heavy Industry continues to research these areas to develop more energy-efficient and environmentally friendly jaw crushers.

This article addresses the common issue of fine sand loss in the production of manufactured sand, which leads to resource waste and reduced efficiency. The primary causes include excessive fine sand proportion, improper equipment selection, and poor moisture control. Solutions involve controlling fine sand generation at the source, choosing appropriate fine sand recovery equipment, utilizing sedimentation tanks for secondary recovery, and managing water volume effectively. These measures aim to minimize fine sand loss and optimize production efficiency.

The impact crusher is favored in the mining industry for its efficiency and versatility. It excels in handling moist materials without clogging, a common issue with hammer crushers that require a bottom screen. The impact crusher's design, featuring a heating device on the impact plate, prevents material adhesion. It also offers a wider range of discharge adjustment. Furthermore, the impact crusher experiences less wear and has a higher metal utilization rate compared to hammer crushers, which wear on multiple sides and have a lower utilization rate. These factors contribute to the impact crusher's popularity and cost-effectiveness.

This article outlines the essential processes and equipment configuration for setting up a sand and gravel aggregate production line. It highlights the importance of each stage, from feeding and coarse crushing to medium crushing, shaping, and final screening. The article emphasizes the use of jaw crushers for coarse crushing, cone crushers for medium crushing, and vertical shaft impact crushers for shaping and sand making. It also mentions the role of pre-screening in optimizing the process and the flexibility offered by a well-designed system. The article concludes by offering customized equipment configuration plans tailored to specific production needs, whether for hard or soft rock crushing, and for mobile or fixed production setups.
