1. The raw material of forged steel ball is hot-rolled round steel. The grain size, non-metallic inclusion, central porosity, ingot segregation and other data comply with the relevant national standards. It has all the characteristics of high-quality steel and becomes a high-quality grinding ball after forging, rotary cutting and heat treatment.2. Rotary cutting steel ball realizes mechanical automation production. The automation degree from steel ball forming to heat treatment is very high to avoid unstable quality caused by manual operation.3.

According to the production and processing technology, steel balls are divided into grinding steel balls, forging steel balls and casting steel balls. According to the processing materials, it can be divided into bearing steel balls, stainless steel balls, carbon steel balls, copper bearing steel balls, alloy balls, etc. Among them, bearing steel ball is an important basic component of industry, and alloy steel ball is a spherical ferroalloy wear-resistant body which is produced by forging, spinning, rolling and casting with carbon, chromium, manganese, molybdenum, etc.

In the field of wear-resistant steel balls, there are two types of steel balls that operate in ball mills or semi-automatic mills, one is forged steel balls (YB/T091-2019), and the other is cast steel balls (YB/T092-2019). Both belong to grinding steel balls and are applicable to different fields such as mining and cement. What are the differences between these two types of steel balls1.

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.

How to Load Balls into a Ball Mill1. The main function of the steel ball in the ball mill is to impact and crush the material, and also play a certain role in grinding. Therefore, the purpose of grading steel balls is to meet the requirements of these two aspects. The quality of the crushing effect directly affects the grinding efficiency, and ultimately affects the output of the ball mill.

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.

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 Material density influence: steel balls, cast iron balls, alloy steel balls, etc. Different materials have different densities. The density of steel is higher than that of cast iron, while that of alloy steel varies according to the density and content of main alloy elements.Stainless steel ballStainless steel ball.② Influence of steel ball manufacturing method: rolled and forged steel balls have dense structure, so the density is high.
