First of all, the main raw material for cement production is limestone. The limestone mined in large quantities needs to be crushed and ground. The quality of the crusher and the hammer head of the grate cooler directly affects the output of the cement plant, especially under the current situation of "limited production and limited electricity" , It is necessary to reduce unnecessary downtime and maintenance. To break this type of hard material, it is necessary to use a high hardness and high wear-resistant alloy hammer with chrome-molybdenum alloy, so as to reduce maintenance costs, reduce downtime frequency and increase production.

If the hammer head is disconnected, it is necessary to consider whether there is an iron block in the feed, and this hidden danger must be eliminated before the machine can be turned on. This situation occurs again, and in extreme cases, it will cause equipment damage, because the broken hammer head cannot be stopped immediately, which will lead to secondary damage to the lining and mechanical equipment.

The bimetallic hammer head formed by thermal compounding at one time is combined into one body when it is in the state of metal or liquid and waits to be cooled, so that the hammer head casted in this way can basically prevent the hammer head from breaking.
