China Carbide Buttons factory Application: High Pressure Grinding Rollers are wildly used in ROCK crush, the roller face are fixed thousands tungsten carbide studs. Protect the studs from being damaged by stress concentration with a hemispherical cap. Round edges guard against damage to the stubs during production, shipment, installation, and use. High compactness and toughness are ensured for the products via HIP sintering.

The capability of output is more than 600tons. Quality Control: Kimberly Carbide has more than 300 quality control parameters, our plants have automatic control system can detect and control turning speed, time, temperature, any abnormity will trip the alarm. According to analyzing and studying the big data record, we continually improve the technological control parameters. Partners: Our customers include: China Shenhua Energy Company Limited, China Railway Construction Corporation, China Huaneng group, Shanxi Coking Coal group, Jizhong Energy Resources Company limited, SANY Heavy Industry Co., Ltd. Changsha Zoomlion Heavy Industry Technology Development Co., Ltd. Market Responds: KB Carbide is very successful in Chinese market, it is supplying carbide buttons to Top 4 mining tools factories in China, and the mining tools are using in many big project. Kimberly Carbide is exporting its products to Finland, Korea, Australia and Brazil, the customers said the quality is at first level. Pre-Production: From the beginning of the production, we have 9 procedures and steps of quality control; we refuse any defect of the products. And we have pre-production system, every batch tungsten carbide powder, we will make it to test bar and check its density, hardness, TRS, KIC, Porosity etc. Package: Inner paper box, outer carton box, banded on pallet or put into pallet box. Transportation: The cargo can be send by sea, by air and by courier. The聽HPGR is an energy-efficient crushing device used to reduce particles by compressing and crushing the feed between two counter-rotating parallel rollers with a small gap between them. This forces the rocks against each other and compresses the density of the feed to 80% of its solid volume, beyond its compressive strength, while applying equal pressure to particles of all sizes. HPGR is widely used for grinding cement clinker, limestone, bauxite, iron ore. 聽 Production technology features 聽 1. The hemispherical protection stud is not damaged by stress concentration. 聽 2. Rounded edge to protect the stud from damage during production, transportation, installation and use. 聽 3. HIP sintering ensures good compactness and high toughness of the product. 聽 4. The special process eliminates the surface stress after surface grinding and increases the surface hardness at the same time. 聽 5. Use grease on the surface of the product to avoid oxidation.China Carbide Buttons factory website:http://www.kimberlycarbide.com/carbide-buttons/
