Qirun supplies 65Mn spring steel grinding bowls for laboratory pulverizers used in mining, geological testing, coal analysis, and mineral sample preparation.
Made from heat-treated 65Mn manganese spring steel, these grinding bowls offer a balance of hardness, toughness, and wear resistance. They are designed for repeated grinding of suitable mineral, rock, cement, and coal samples.
Available in multiple sizes, our 65Mn grinding bowls support OEM customization based on equipment models, drawings, and replacement component dimensions.

The listed material composition, hardness, and capacity range follow the published product information. Specific dimensions, capacity per model, tolerances, and equipment compatibility require confirmation.
65Mn is a high-carbon manganese spring steel known for its response to heat treatment.
Through appropriate quenching and tempering, the material can achieve hardness and strength suitable for repeated mechanical loading.
This combination makes 65Mn a practical option for laboratory grinding bowls that require both wear resistance and impact tolerance.
The published hardness range of HRC 55–65 helps provide resistance to abrasive contact during sample pulverizing.
Actual performance depends on the final heat treatment, sample properties, grinding intensity, and operating conditions.
Regular inspection is recommended to identify wear before it affects grinding efficiency or component fit.
Qirun offers grinding bowl models including 200, 400, 800, 1000, and 2000.
Customers can select a suitable configuration according to sample preparation requirements and pulverizer specifications.
Before ordering, the bowl capacity, external dimensions, mounting design, and grinding components should be confirmed.
Grinding bowl dimensions and mounting surfaces are important for correct installation in laboratory pulverizers.
Our manufacturing service supports machining based on customer drawings and component specifications.
Proper dimensional matching helps ensure that replacement bowls are suitable for the designated equipment.
Qirun supports customized grinding bowl production for laboratory and industrial sample preparation equipment.
Customers can provide existing component drawings, worn-part dimensions, or pulverizer specifications for technical evaluation.
Custom requirements may include bowl dimensions, material grade, cavity geometry, and mounting arrangements.
65Mn spring steel offers a different material balance from high chromium steel and tungsten carbide.
It is generally considered when customers require heat-treatable steel with useful toughness and wear resistance at a practical material cost.
Feature | 65Mn Steel | High Chromium Steel | Tungsten Carbide |
|---|---|---|---|
Main Advantage | Balanced toughness and hardness | High abrasion resistance | Very high hardness |
Impact Tolerance | Grade and heat-treatment dependent | Generally more limited in hard, carbide-rich grades | Brittle under severe impact |
Wear Resistance | Good under suitable conditions | High | Very High |
Relative Material Cost | Generally Lower | Moderate | Higher |
Typical Selection | General mineral and coal sample preparation | Abrasive mineral samples | Highly abrasive samples requiring very high wear resistance |
Material selection should also consider sample contamination. Steel grinding components can introduce iron, manganese, or other trace elements during wear, so they may not be suitable for every analytical test.
