Summary:SBM offering stone mill grinder covers different Raymond mill, vertical mill, ultrafine mill and ball mill – optimized for any size reduction need.
Stone grinding mills are machines used to reduce the size of rocks and stones in aggregates production, construction material recycling applications, and in mining operations. SBM has designed, engineered and manufactured stone mill grinders for more than 100 years. Our offering covers different Raymond mill, vertical mill, ultrafine mill and ball mill – optimized for any size reduction need.
Different Types Of Mills Are Optimal For Distinct Powder Fineness
The pulverization equipment portfolio of SBM includes all important anges in terms of powder fineness.
why is ore grinding necessary
The reasons for the grinding of industrial materials are numerous but the principal reasons may be summarized under the following headings:
The liberation of an economically important material from the un-required constituents of a mixture.
The exposure of a large surface per unit mass of material in order to facilitate some chemical process.
To reduce the material to the desired form of the final product.
To satisfy market requirements.
Examples of the first two classes occur in mineral dressing, in which size reduction is used to liberate the desired ore from the gangue and also to reduce the ore to a form in which it presents a large surface to the leaching reagents.
selecting a suitable stone grinding mill
To choose the right product not only precise knowledge of the instruments is required but also profound experience in the preparation of different materials. To find the best suited grinding mill for a specific application, the following aspects should be considered in advance:
- Quality/characteristics of sample (e.g. dry, tough, abrasive, fibrous, brittle, hard, soft, temperature-sensitive etc.)
- Feed size
- Required final fineness
- Sample volume
- Sample throughput
- Subsequent analysis (which type of contamination by abrasion of grinding tools is acceptable?)
- May the sample be dried or embrittled before grinding?
Depending on the quality of the material different size reduction principles are applied to obtain the required fineness. Large particles cannot always be ground to analytical fineness in one step. In some cases it is possible to carry out coarse and fine grinding in the same grinding mill with different settings;
frequently asked questions about stone grinder mill
Q: how long time does the stone last?
The mill stone will last several years, depending on what you grind and how many hours per day you operate.
As an overall, our mill stone grinder will last up to 3 years before you need to change it.
This is based on running the stones 8 hrs per day for 6 days per week.
Q: can i buy spare parts for my stone grinding mills?
Yes, we have spare parts available for our whole range of grinding mills, sifters, and accessories.
Q: can you help with installation?
Yes, we have a full installation team that we will send out; both for installation, training, and commissioning.
