AT THE GLANCE----OURFACTORY
Welcome to Goldpro, where you will find high quality milling steel ball products and services at competitive prices.Our main products incuded: forged steel balls, rolling steel balls, and cast steel ball, which widely used in mine industry.Grinding steel balls is necessary for ball mills, our products have the advantages as following: 1.High hardness, and hardness gradient uniform distribution. the tolerance of hardnessis2~3HRC, which gurantee the balls with good roundness. 2.Low breakage rate, according to the industry standard in our courtry, the breakage rate of ball is less than 1%. 3. Good machanical properties, in processing, the balls quenched in water, subsequent tempering. Keep the ball under 180~220 celcius, make the ball have good impact properties. The machanical properties of steel balls have good impact to the mill liners and ball mills. 4.Chemical composition, the raw materials of our products are alloy steel bars which the chemical composition is stable and accurate. 5. Overall quality control, we bulit our own quality inspection centre. 6.Enviromental, In processing, treatment by gas, low energy consumpation, and no pollution. During wet prcessing in ball mills, never output heavy metal element which will pollute the water and soil. We manufactures different steel balls for different mines. the steel ball special for gold mine, for silver mine, for cooper mine, and molybdenum mine. Welcome to the concentrator plant all over the world inquiry our productsTell us the diameter of balls you need. According to the range of hardness,
we recommend best grinding ball to you.
