Introduction: The ball mill is a tumbling mill that uses steel balls as grinding media. Ball mills can be used in wet or dry systems for bulk and continuous milling, and are most widely used in small or large-scale ore beneficiation plant. Dry grinding: suitable for materials that react with water, such as building stones such as cement and marble.

The albite feldspar mining process is mainly: • Crushing: The raw ores are crushed roughly (in jaw crusher) and middling (in cone crusher) into 20mm. • Grinding and classification: Crushing product is …
There are many options for fine crushing and grinding machines of the feldspar processing plant, mainly roller crusher, impact crusher, sand making machine, hammer crusher, stone grinding, column mill, tower mill, Raymond mill, stirring mill, vibration mill, sanding mill, and airflow mill, etc.
The effect of the grinding time, the grinding media filling rate and the powder filling rate were tested by grinding the ore in a lab ball mill. Mono size balls (15 mm) were used as the grinding media. The characteristics of the lab-scale ball mill and the test condition are shown in Table 3.
The porcelain body recipe is the same (close to equal parts of M23 ball clay, #6 Tile kaolin, feldspar and silica ). But the top bar uses Nepheline Syenite (as the feldspar) and the bottom one Custer Feldspar. Melt flow comparison between Nepheline Syenite 270 and 400 mesh Tap picture for full size
The effects of various parameters were investigated in a detailed study by present authors (Gökçen et al., 2012) and optimum grinding conditions were determined to be a stirring speed of 600 rpm,...
the drying process, dry grinding is sometimes performed to reduce the feldspar to less than 74 µm (200 mesh) for use in ceramics, paints, and tiles. Drying and grinding are often performed simultaneously by passing the dewatered cake through a rotating gas-fired cylinder lined with ceramic blocks and charged with ceramic grinding balls.

In general, the use of the dry or wet technique in grinding makes differences in kinetics. It is a well-known fact that it is challenging and highly time-consuming to achieve ultra-fine particle sizes in the dry environment of a typical tumbling ball mill.
Steel balls of 5, 8, and 15 mm diameter were used as the grinding media, in a ratio of 3:5:2. Each grinding was performed with 60 g of feldspar in a 500-mL steel can containing 600 g of hardened steel balls. In each grinding run, the feldspar samples were ground for periods ranging from 10 to 200 min.
