Diaphragm of Cement Mill
cement mill diaphragm
Intermediate diaphragm of the Cement Mills
Alloyed high manganese steel Diaphragm
The barrel is divided into intermediate baffles of two or three grinding bins. Theseparating wearhouse plate has holes that are smaller than the diameter of the steel balls in the two abrasive cavities to allow the material to pass through and be further milled. Due to long-time friction between steel balls and materials in the two sides of the abrasive silo, the silo panel needs to be very wear-resistant to shorten the replacement cycle. Some ball mills use double-layered diaphragms to better distinguish the two abrasive cavities and prevent them from collapsing and damaging the body.
The double storey partition board is also a kind of separating wearhouse plate, and the materials used are basically the same.

Feature:
We use proper alloying and and related technological measures to make the blow bars’ surface hardness reaches more than 58HRC , during the process of wearing will maintain high hardness and high wear resistance.
Technology process
In blow bars’ working part we use the technique of directional solidification to make Cr7C3 type carbide is perpendicular to the part.The macro-hardness and micro hardness of carbide can be improved without reducing thoghness.
Application
Suitable for making wearable spare parts with lower impact load and simpler shape.

Feature
High manganese steel refers to high alloy steels containing more than 10% manganese. The biggest features of high-manganese steel are:
The greater external compressive stress or impact load, the more conducive to the formation of hardened layer, so the higher the wear resistance of the casting;
With the gradual wear of the hardened layer, new work hardened layers will continue to form under the influence of external compressive stress or impact loads. Therefore, it is suitable for making wearable spare parts that are subject to high impact load and wear for a long time, and is widely used in metallurgy, mining, building materials, railways, electric power, coal and other broken grinding equipment.
