TBM (time-based) for hammer maintenance has predictability but risks misalignment with actual wear. PBM (production-based) fits actual conditions but needs tracking. Hybrid models and tech bridge gaps.
"Scars" Can Speak: How to Predict Crusher Equipment Failure by Liner Wear Marks?
Analyzing wear patterns on crusher liners is a non-invasive method to predict potential equipment failures. The distribution, shape, and severity of wear marks provide vital clues about operational abnormalities.
Grate Bar Selection Guide: How to Choose the Pore Structure According to the Fuel Characteristics?
The porosity structure of grate bars plays a crucial role in combustion efficiency and should be carefully matched to fuel properties.
How to Judge Whether the Liner and Other Parts of the Jaw Crusher Need to Be Replaced?
How to judge jaw crusher part replacement: observe operation, check wear/ production data. It notes replacement cues (output drop, uneven particles, etc.) and advises regular checks, especially for high-hardness materials.
Analysis of China's Crusher Export Trends in Recent Years
China's crusher exports grow steadily (2021-2023 avg 9% annual growth), driven by "Belt and Road" infra demand. Products upgrade to high-end, with SE Asia/Africa as core markets.
High manganese steel (good impact resistance) suits jaw crusher parts for coarse crushing hard materials, while high chromium steel (wear-resistant) fits fine crushing. With the advancement of materials science, composite accessories that combine the advantages of two materials have now appeared.
Lost foam casting for furnace grate bars has pore issues affecting life. Coated sand casting excels in precision/density, cutting creep rate by 57% and boosting yield, suiting grate bar making.
Shandong Jiujiu Machinery participated in the 23rd China International Foundry Expo
On May 20, 2025, Shandong Jiujiu Machinery (Booth S1-D09-1) exhibited castings at Metal China in Tianjin, received global visitors and captured customer needs accurately.
In industrial production, whether the core components of the impact crusher, such as the liner and hammer, need to be replaced is mainly judged by comprehensively observing the operating status, wear characteristics and production efficiency of the equipment.
