Product Description

Working principle of open mill: 

In the mixing process, the open mixing mill is mainly dependent on the relative rotation of the two rollers to the extrusion and cutting of the material. After repeated kneading and chemical action with the process, it finally achieves the purpose of mixing through the interrupting of the molecular chain of material internal and mixing all the ingredients in the recipe evenly. 

Machine application:
Suitable for blending, dispersing, shearing, plasticizing, cooling, and laminating polymer materials such as rubber and plastics.

Features and advantages: 

1. Rollers material: the roller is made of high-quality carbon steel by nitriding treatment. The German machine tool makes the center height, its thickness is uniform, the control is precise, the surface is plated with hard chrome, the bearing capacity is strong, and the service life is long.
2. Roller bearings, and lubrication: Bearing-type double-arranged ZWZ bearings, self-adjusting, and integrated lubrication system, easy to maintain, greatly improve equipment life.
3. Safety design: ergonomic multi-directional brakes, emergencies, convenient and timely touch according to the natural reaction of human body, infrared safety switch.
4. Safety switch: the machine adopts 360 degree non-dead safety dial switch in multiple directions, and the safety protection is good.
5. Safety protection: The whole body adopts all-round wrapping for all transmission parts, and a new curved safety cover is adopted at the roller to isolate the operation danger.
6. Transmission system safety: the machine adopts electronic brake, lotus coupling, single-axis output system, large torque, stable transmission, safe device convenient machine 1/2 second quick stop, and outward reversal function (circle speed adjustable), reaction Speed is the industry leader.
7. Temperature control system: temperature control, automatic temperature control, integrated waterway cooling in place and protection to reduce pollution from circulating water sources. And the use of high temperature rotary joints, long service life and good sealing effect.
