​Open mill, also known as open mill, It is a kind of rubber and plastic machinery developed on the basis of the internal mixer. The open mixer is mainly used for mixing and plasticizing of rubber or plastic. Different from the internal mixer, the open mixer can also be used for rubber sheeting. Or plastic sheets, and the price is generally lower than that of the internal mixer.

​

Rubber mill, as its name suggests, is mainly used for rubber mixing. Made of international quality vanadium-titanium alloy steel, two hollow rollers or drilling rollers that rotate inward in opposite directions are called front rollers installed on the operator's side, which can be moved horizontally back and forth by manual or electric action. Adjust the roller distance to meet the operation requirements; the rear roller is fixed and cannot be moved back and forth.

Working principle of rubber mill:

The two rollers rotate relative to each other. Different rotation speeds cause shear and pressure to the material, thereby breaking the molecular chain of the material and achieving the effect of industrial mixing. During the mixing process, the operator usually adds some rubber additives to fully mix the material. Making materials suitable for industrial needs, on the other hand, can also reduce costs. The general hardness of rubber is relatively low, so the rubber mill is also called a water-through mill.

The rubber mill is different from the plastic mill. The rubber mill is also called a water-passing mill. There is a water pipe joint, and the water pipe is directly inserted to make the water enter the machine, thereby opening the effect of cooling and water flow; while the plastic open mill is called a heating type open mill, because the hardness of the plastic is generally high, and the mixing process needs to be Heating can fully mix the plastic.
