Open mill

Technical Field

The application relates to the field of chemical machinery, in particular to an open mill.

Background

An open mill is a short name for an open type plasticator, and is also commonly called a two-roller mill in plastic product factories. An open mill is a plastic mixing device which is applied earlier by plastic product factories. The open mill is used for mixing and plasticizing the uniformly mixed raw materials and providing a molten material which is uniformly mixed and plasticized for the plastic products which are calendered and formed by the calender.

The main working parts of the open mill are two hollow rollers rotating inwards, the hollow rollers are called front rollers on one side of an operator, the two rollers are generally the same in size and rotate relatively at different speeds, and rubber materials are rolled into a gap between the two rollers along with the rotation of the rollers and are subjected to strong shearing action to achieve the purpose of plastication or mixing.

In view of the above-mentioned techniques, the inventors have considered that, since the raw materials fed to the roll are generally in the form of a dough during kneading, it is difficult to uniformly distribute the dough on the roll, and the kneading effect and efficiency may be impaired.
