This machine is used for basic and preliminary dressing, making it possible to significantly raise the quality of concentrated ore and the ore dressing rate.

The researchers conducted experiments which led to optimizing the integral value of the factors which have a decisive impact on dressing rate such as diameter and angles of rotary and fast pressure on ore. In this course they succeeded in completing a design for the above-said dressing machine.

The introduction of this machine to the process of magnesium hydroxide confirmed that its distribution and dressing rate is about 5 to 10 percent higher than that of ordinary rotary dressing machine.

This machine is used for distributing and dressing all crushed minerals as it guarantees maximum dressing rate in the preliminary dressing process.
