Melin’s Hard Nip Calender is stably and successfully running in bigpaper mill lines! Many thanksfor the hard working and support of alltechnicians,staffs and paper mills!   This calender with oil heated roll and crown compensation roll isreplacing imported products with its superior material and processing while costis more acceptable. It has the following advantages:

  Due to the installation of a deflection compensated roll it ispossible to achieve a uniform line load distribution over the entire sheet widthand line load range. This type of calender allows a very flexible adjustabilityof the nip load and temperature.

  Material of the roll is manufactured from forged steel. The shell ispolished once a year. Polishing is done on common grinder. The common calenderis from chilled cast iron and the crown value needs to be grinded every threemonths . Grinding is to be made on the roll grinder which is not convenient toget.

  Good quality paper can be produced.

  Bulk and ink absorbent for paper is increased.

  With top oil heated roll treatment, the paper web is smooth andprinting performance is improved.

  As basic paper weight changes and the crown is different, Unlike thecommon calender, this crown controllable hard nip calender can make evenpressure on the paper surface.

  Top roll can be heated. Temperatures of two rolls are kept constant.The deformation of roll is stable. Paper passes the nip evenly.
