Production capacity analysis of ball mill and rod millBoth ball mill and rod mill are important mining mills, and their production capacity is related to the following factors: ore grindability, particle size of feed ore and final product, type and size of grinding machine, shape of liner, The shape, size, proportion, hardness and density of the grinding medium, the number of revolutions of the mill, the filling rate of the grinding medium, the grinding concentration, the amount of sand returned and the working efficiency of the classification equipment, etc.

According to the manufacturing and processing technology, steel balls are divided into grinding metal balls, forging metal balls and casting metal balls. According to the processing materials, it can be divided into bearing metal balls, stainless metal balls, carbon metal balls, copper bearing metal balls, alloy balls, etc.

I. First of all, take iron ore as an example: most mines generally use low chromium ball or forged steel ball, and its current price is about 5000 yuan/ton, and the consumption of grinding body per ton of concentrate powder is about 3Kg. If we use our company's special high chromium ball for mine, the current average price is 7000 yuan/ton (excluding freight, the same below), and the consumption of concentrate powder per ton is 1.5Kg/T.

May 28th, 2022, a group of four businessmen from Finland Qingdao office visited Shandong Jinchi Heavy Industry Co.

When producing forged steel balls, the following points should be noted:During forging, the temperature of steel will rise, so pay attention to prevent burns and scalds.During the forging process, the steel will be subjected to high pressure and hammering, so care should be taken to prevent accidental injury.A lot of noise and vibration will be generated during forging, so attention should be paid to hearing protection and body protection.A lot of heat and smoke will be generated during forging, so good ventilation and respiratory protection shall be paid attention to.The shape of steel will c

For a long time, some ferrous metal (iron ore) and nonferrous metal beneficiation industries at home and abroad still use low chromium ball and forged steel ball as abrasives and are still widely used.

1.Select the gorgeous steel. Forged steel balls are typically made of carbon metal or alloy steel, relying on the reason of the metal balls you favor to produce.2.Pre deal with the steel. This step typically consists of warmness treatment, cooling and metal processing.3.The metal is put into a forging computing device for forging. This step normally consists of two stages: warm forging and bloodless forging.
