Steel balls are steel cast and hot rolled steel. The latter are sometimes called forged steel balls.
- Cast steel balls. The production uses scrap metal, which is heated in an electric furnace until completely melted. When the iron has reached the required temperature, the molten cast iron is removed from the furnace. It is poured into steel balls. In other words, cast steel balls are those balls that are produced by casting and smelting.
- Cast chrome alloy balls. These products are divided into another classification depending on how much chromium is contained in the sphere. They are cast balls of chromium alloy, cast balls of medium chrome alloy and cast balls of chrome alloy.
Products have the following advantages:
- reduces the specific consumption of grinding bodies by 1 ton of production;
- reduces electricity costs by 1 ton of production; in practice, savings range from 8 to 10 per cent;
- increase the productivity of mills, so the quality of grinding raw materials is significantly improved;
- reduces the mill’s load rate, maintaining the grinding quality and productivity achieved;
- reduces the time spent on maintaining the mill;
- optimize inventories;
- eliminates the «facets of tension», as compared to cylpeps steel balls the risk of splitting is minimized;
- contributes to a more dense filling of the voids; this is due to the fact that the grinding balls of the raw material are washed evenly, keeping the original shape in the form of a ball;
- are able to regulate grinding quality, as grinding balls can have different diameters;
- having equal sizes, grinding balls for raw materials in different industries have a large surface area.
In conclusion, steel balls are the ideal way to grind raw materials in cement, coal and other industries.
