The sand is separated and filtered by the vibrating sieve, and then the casting is rolled into a high-speed rotating barrel. The separated casting ball mill balls and the gating-risers enter into the vibration sorting mechanism at the same time. The ball and the gating-risers are classified by the principle of vibration conveying. The results […]
Generally speaking, the end customers of wear-resistant materials companies mainly include mining, cement, construction and power plants. The performance of the wear-resistant steel ball is related to the cost and benefit of the end-user enterprise. At present, with the technical improvement of wear-resistant casting companies, the replacement of low-efficiency steel balls with high-performance and high-grinding […]
Keep the hardness just right. When we choose wear-resisting grinding media ball, often be the hardness problem of the grinding media ball. About the hardness, not the bigger the better, is the appropriate hardness value. Simply put, the higher the hardness, the greater the impact reaction during the process of falling, increasing the ball loss. […]
The ball mill steel ball is also called the grinding body, is the medium of the ball mill grinding material, belongs to the consumable, the main use is the grinding material, causes the material to grind to achieve the certain fineness, when chooses the ball mill steel ball, the enterprise often after the ball hardness […]
The ball mill grinding ball on the market now can be divided into two kinds according to the manufacturing process: Cast grinding Ball and forged steel ball, but their wear degree is not the same. Due to crushing and pulverizing materials, grinding balls need good abrasion resistance and enough impact toughness, and require steel balls cannot be broken, […]
High Chromium White cast iron grinding ball is also known as high chromium alloy casting ball, high chromium steel ball, referred to as high chromium ball. At present, most of the domestic wear-resistant material enterprises take the medium frequency electric induction furnace as the main body, through the reasonable matching of high-quality scrap steel, chromium […]
Ball mill is widely used in building materials, mineral processing, cement, thermal power generation and fertilizer production of the main grinding equipment, grinding ball is the largest consumption of wear-resistant parts. Therefore, with the continuous development of key industries such as building materials, the demand for grinding balls will increase greatly. At present, ordinary forged […]
The AUTOMATIC SAND-COATED METAL MOULD PRODUCTION LINE adopts the advanced sand-coated metal mold producing process, which can significantly improve the mechanical properties of castings, improve the appearance quality of castings, reduce the machining allowance of castings & the labor intensity & the number of workers, minimize the production of safety hazards.
Written by LI Ju-cang, ZHAO Ai-min, WANG Li-na (University of Science and Technology Beijing, Beijing 100083, China) Abstract： The effects of heat treatment on the hardness, impact toughness, manufactured process, and microstructure used different heat treatment technology of dia50 mm Cr26 high chromium cast iron grinding ball have been studied. The results show that hardness of […]
ABSTRACT: The heat treatment process of high chromium grinding ball produced by sand coated iron mould casting process was researched. Shrinkage and porosity defects have not been discovered after cutting along the diameter of grinding ball. The grinding ball in cast state has poor mechanical properties. Mechanical properties of grinding ball significantly increase after heat treatment After heat […]
