Round Mild Steel Ball Mill Diaphragm Corrosion Resistant Spare Parts
We supply partition plates from multiple worldwide brands. We can also design, customize and produce them based on your working‑condition demands.
As intermediate components, these partition plates split the mill drum into two or three grinding chambers. Their openings are smaller than the steel‑ball size of adjacent chambers, enabling material to pass through for further pulverization. Suffering persistent friction from steel balls and materials on both sides, partition plates need superior wear resistance to lower replacement frequency. Some ball mills use double‑layer partition plates to achieve better chamber separation, stop cross‑flow and protect equipment from damage.
Double‑layer partition plates belong to this series and share mostly the same material composition.
About This Product
Ball Mill Diaphragm / Compartment Plate
A diaphragm (also called compartment plate) is the intermediate partition that divides the mill cylinder into two or three grinding chambers. It features openings smaller than the diameter of the grinding balls in the adjacent chambers, allowing only sufficiently fine material to pass through for further grinding. Subjected to continuous friction and impact from grinding media and materials on both sides, diaphragms must be highly wear-resistant to minimize replacement frequency. Some ball mills use double-layer diaphragms to better separate the grinding chambers, prevent cross-chamber mixing, and avoid damage to the mill body.
Double-layer diaphragms are a type of diaphragm and use essentially the same materials.

High‑Chromium Cast Iron
Material Features
Through proper alloying and relevant technical measures for high‑chromium cast iron castings such as liners and hammers, the hardness of the entire cross‑section can reach above 58 HRC. It maintains high hardness and excellent wear resistance during the wear process.
Process Technology
Directional solidification is adopted for the working surface. M₇C₃‑type carbides are vertically distributed on the working surface. Without sacrificing toughness, both the macroscopic hardness and micro‑hardness of carbides are improved.
Scope of Application
Suitable for manufacturing wear‑resistant spare parts with low impact load and relatively simple shapes.

Notes:
- Trace elements V, Ti, Nb, B and RE can be added.
- Grade and specific composition range can be selected according to the weight, thickness and specification of liners/hammers.

Notes:
- There is no precise corresponding value between Rockwell Hardness (HRC) and Brinell Hardness (HB). The two hardness values shall be used independently.
- The hardness at 40% depth of casting cross‑section shall not be less than 92% of the surface hardness.
High‑Manganese Steel
Material Features
High‑manganese steel refers to high‑alloy steel with a manganese content above 10%. Its characteristics are as follows:
The higher the external compressive stress or impact load, the more favorable it is for forming a work‑hardened surface layer, which improves the wear resistance of castings.
As the surface‑hardened layer gradually wears away, new work‑hardened layers will continuously form under external compressive stress or impact load. Therefore, it is suitable for manufacturing wear‑resistant spare parts subject to long‑term material abrasion under high impact loads. It is widely applied in crushing equipment for metallurgy, mining, building materials, railway, electric power, coal and other industries.
