WhatsApp: +86 18838072829Fig: Principle of openend rotor spinning. The input sliver is first opened and drafted by the opening roller. The fibres are transported via a tube to the rotor where the fibre strand is subjected to twist insertion. After twisting, the output yarn is then wound into 'cheese'or 'cone' packages of the required size.
WhatsApp: +86 18838072829The rotational speed of the vertical spindle mill affects the operating conditions of the grinding unit. At high rotational speeds, the grinding unit operates at high flow of the material in the radial direction and low layers of the material under the grinding elements (balls, rollers). This causes the particles to be discharged without ...
