The manual roller machine is mainly suitable for manual rolling of battery materials in the laboratory, a small amount of precious metal materials such as gold and silver, and non-ferrous materials such as copper and aluminum. It is especially suitable for thinning and increasing density of lithium battery plates for clean energy materials.

Manual roller press machine are often used for initial compaction of electrode materials. The positive and negative electrode materials need to be pressed into sheets to improve their energy density and performance stability.
