Nov 26, 2020 The PETP granules were milled on an IKAA 11 mill to a powder with particle sizes of less than 1 mm. This was followed by preliminary drying in a vacuum cupboard to remove residual moisture from the PETP powder and the nanofiller. The nanofiller and the PETP were then mixed in specific amounts for 30 min at room temperature in a vibrating ball mill.

220.127.116.11 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter Figure 8.11. The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 2040 water by weight.
RETSCH MM 400 Mixer Mill. Developed specially for dry, wet, and cryogenic grinding of small amounts of sample. The MM 400 Mixer Mill provides powerful grinding by impact and friction, up to 30 Hz for up to 20 samples per run. The degree of mixing can be increased even further by using several smaller balls.
Cutting mills are suitable for the grinding of soft, medium-hard, tough, elastic, fibrous, and heterogeneous mixes of products. The Cutting Mill SM 400 is ideally suited for pre-cutting of large sample pieces but, depending on the application, may also achieve the required fineness in one step.
This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types grid type ball mill and overflow type ball mill.
