This article highlights the performance and advantages of sand produced by sand making machines. It emphasizes that manufactured sand is comparable in quality to natural sand and can be tailored in size. Key benefits include controlled composition, adjustable fineness modulus, superior adhesion and compressive strength due to particle shape, and acceptable stone powder content. These advantages address the shortage of natural sand and promote efficient resource utilization.

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 bearing damage in circular vibrating screens, a crucial piece of equipment in various industries. Improper bearing selection, incorrect fit tolerances, inadequate lubrication and sealing, and neglecting shaft thermal expansion are identified as key causes. Solutions include choosing the right bearing type (cylindrical or spherical roller bearings), ensuring proper fit tolerances, adopting thin oil lubrication systems, and designing for shaft thermal expansion. These measures can significantly reduce the risk of bearing failure and extend the equipment’s lifespan. For further assistance, consulting with experts like those at Dingbo Heavy Industry is recommended.

This article addresses the critical issue of a Raymond mill’s motor failing to start, which halts production. It outlines the primary causes for this problem, including power issues, low overcurrent relay settings, excessive motor load, and incorrect wiring. The article then provides practical solutions for each cause, such as checking and repairing electrical components, adjusting relay settings, reducing the motor load, and correcting wiring errors. Understanding and addressing these issues is crucial for maintaining uninterrupted operation and optimal performance of the Raymond mill.
