Size control is the process of separating bulk material into two or more products on basis of
their size. In mineral processing practices, two methods dominating size control processes
are: screening and classification. As shown in the following figure, while screening uses a
geometrical pattern for size control, classification uses behavior of particle’s (finer than 1
mm) motion in air or liquids (water) for size control.

Sizing is extensively used for size separations from 300 mm down to around 40 μm (micron),
although the efficiency decreases rapidly with fineness. Dry screening is generally limited to
material above about 5 mm in size, while wet screening down to around 250 μm is common.
Although there are screen types that are capable of efficient size separations down to 40
μm, sizing below 250 μm is also undertaken by classification. Selection between screening
and classification is influenced by the fact that finer separations demand large areas of
screening surface and therefore can be expensive compared with classification for high
throughput applications.

In the world of plastic manufacturing, precision matters. Whether you're producing packaging materials, automotive components, or consumer electronics, understanding how your raw materials behave under heat is essential. One of the most important indicators of a thermoplastic material’s processing performance is its Melt Flow Rate (MFR) or Melt Volume Rate (MVR). This is where the GBB-R Melt Flow Index Tester, developed by Guangzhou Biaoji’s expert R&D team, comes into play.

What Is Melt Flow Rate, and Why Should You Care?

The melt flow rate refers to how easily a thermoplastic polymer flows when melted under specific temperature and load conditions. It's measured by how much material extrudes through a standard die over a given period. This value—expressed as either mass (MFR, g/10min) or volume (MVR, cm³/10min)—can significantly impact the molding and extrusion behavior of the material.

Imagine producing a batch of polypropylene components. If the MFR is too high, the material might flow too quickly, leading to flash or overpacking. Too low, and the mold might not fill properly, causing structural defects. Knowing the exact melt flow rate helps technicians fine-tune their processing parameters, reduce waste, and ensure consistent product quality.
