Ball mill is a essential equipment for further grinding the material after it is crushed. It continues to grind minerals by grinding media to reach a certain fineness to achieve a better grinding effect. Most of mines use overflow ball mill. The mineral will gradually flow to the discharge end with the rotation of the cylinder and the movement of grinding media, and finally overflow from the hollow journal of the discharge end. Therefore, compared with the SAG mill, the diameter of ball mill,the particle size and the ball size is smaller;the running speed is relatively decreased and the filling rate is higher. The grinding balls mainly impact and grind minerals by cascading, and can’t discharge unless the balls reach the specified size,which required high wear resistance. However, the attrited and deformed grinding balls have lower production efficiency and occupy the ball filling rate. If the balls still have a high hardness and cannot disappear quickly, this situation will cause energy waste and increase consumption.
After the in-depth discussion and analysis of Goldpro New Materials Co., Ltd., with the research and analysis of invalidation principle ,working condition and heat treatment process, Goldpro has developed a grinding ball for ball mill. Within the effective volume,the ball is of high hardness and better wear resistance,and the hardness is appropriately reduced at the smaller diameter, ensuring that the grinding effect and the effective filling rate in the ball mill , thereby improving the grinding efficiency , saving energy and decreasing wear rate. Practice of a large foreign mines,Goldpro’s grinding balls decreased wear rate by 15% to 20%,and has been fully approved by the mine leaders and engineers.
Strictly implement the ISO9001:2008 system, and established a sound product management and control system, product quality testing system and product trace system.
With international authoritative quality testing equipment, the testing specifications are qualified with the CNAS (China National Accreditation Service for Conformity Assessment) certification system;
The testing standards are fully calibrated with SGS (Universal Standards), Silver Lake (US Silver Lake), and Ude Santiago Chile (University of Santiago, Chile) laboratories.
Three “entire” concept
Three“ entire” concept includes:
Entire quality management, entire process quality management and entire participation in quality management.
Entire quality management:
Quality management is embodied in all aspects. Quality management not only includes product quality, but also needs to consider factors such as cost, delivery time and service. This is the significant entire quality management.
Entire process quality management:
Without a process, there is no result. Entire process quality management requires us to focus on every aspect of the value chain to ensure the quality results.
Entire participation in quality management:
Quality management is everyone’s responsibility. Everyone must pay attention to product quality, find problems from their own work, and improve them, to take responsible for the work quality.
Four” everything” concept
The four “everything” quality concept includes:everything for customers, everything based on prevention, Everything speaks with data, everything works with PDCA cycle.
everything for customers. We must pay more attention to customers’ requirements and standards and establish the concept of customer first;
Everything is based on prevention. We are required to establish a concept of prevention-oriented, prevent problems before they occur, and eliminate the problem in its infancy;
Everything speaks with data. We should count and analyze data to trace the roots to find the essence of the problem;
Everything works with PDCA cycle. We should keep improving ourselves and use system thinking to achieve continuous improvement.
