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.

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.

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.

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.

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.

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

1.Select the appropriate steel. Forged steel balls are usually made of carbon steel or alloy steel, depending on the purpose of the steel balls you want to produce.2.Pre treat the steel. This step usually includes heat treatment, cooling and steel processing.3.The steel is put into a forging machine for forging. This step usually includes two stages: hot forging and cold forging. Hot forging is the process of heating steel to a high temperature and then shaping it with hammer or pressure.

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.
