Companies focused on crushing look to optimise their work with equipment and machinery that guarantee the investment will deliver the expected result. Choosing the horizontal shaft impact crusher a company needs is a vital decision. But whatever problem arises, Aceros y Suministros will provide the answer you need. We manufacture the spare parts your horizontal shaft impact crusher (HSI) may require, backed by the best guarantees on the market: blow bars in different alloys according to the working conditions of the crusher, impact plates, side liners and shoes. Aceros y Suministros also manufactures blow bars and impact plates with ceramic inserts.
How horizontal shaft impact crushers work
Basically, the feed material enters the primary chamber, where the impact blow bars crush it by throwing it against the impact plates. These plates are usually designed with sharp edges. This is so that they penetrate the material, causing high pressure as well as bending stress. The crushed fractions pass to a second grinding stage, while those not crushed in this first stage return to the primary chamber. The material from the second chamber passes to a third, where the final grinding takes place.
Precisely because of the work this type of equipment does, it can suffer higher wear than expected, even though that is exactly its purpose. And it is true that, as technology advances, horizontal shaft impact crushers are increasingly resistant and durable. But parts still wear out with use.
Equipment that suffers wear
The new operating systems of these impact crushers are increasingly efficient, at least from an energy standpoint. If we combine energy savings with lower wear on the plates, or the greater durability of the components, we can see why costs can be reduced.
The materials used to make the components of an impact crusher are not chosen at random, quite the opposite. The forged steel generally used for the rotor shaft is welded with anti-wear solutions. This is especially important in the areas where abrasion is highest. Blow bars, impact plates and liners can be made in new alloys composed of base steels and ceramic inserts. These new ceramic alloys have greatly improved the life of the main wear parts, increasing productivity and reducing the number of parts to be replaced, and therefore reducing emissions in both manufacturing processes.
Although this equipment is robust, reliable and efficient, that does not mean it has no parts that wear out. It may even happen that they fail. At Aceros y Suministros we have an engineering team that will manufacture the spare part your horizontal shaft impact crusher needs as if it were the original manufacturer's own. We can confirm that most Aceros y Suministros spare parts offer a longer wear life than the original part.
