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 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.

The impact crusher, also known as the impact breaker, is a widely used crushing machine that plays a vital role in infrastructure construction such as railways, highways, and hydropower projects. Known for its high efficiency in medium and fine crushing, it is especially effective in processing hard materials and recycled aggregates. Key features include a broad material applicability, flexible discharge size adjustments through rotor speed, distributor settings, and chamber gap control, as well as reduced wear on components and ease of maintenance. With a full range of models and configurations, the impact crusher meets diverse production demands across industries.

This article explores the crucial material requirements and their impact on vibrating screen performance. Key factors include moisture content, where external moisture affects flowability and can lead to clogging, especially in fine-pore screens. Clay content is another critical aspect, as materials prone to agglomeration, like clay, can cause screen clogging even with low moisture levels. Particle size characteristics, particularly the distribution of particle grades, influence screening efficiency, with pre-screening methods improving performance when fine particle content is low. Finally, density characteristics of the material, where differences in density between coarse and fine particles affect screening ease, are discussed. Understanding these material properties is essential for optimizing vibrating screen operation and achieving efficient separation results.
