Open type rubber (plastic) rubber mill is referred to as open kneader, rubber kneader for plasticizing, hot smelting and mixing of rubber. It is mainly used for hot smelting, mixing, and plasticizing of raw rubber. It can also be used for tabletting. The roller is used to cut and squeeze the rubber material. 。 It achieves the processes of plasticizing raw rubber, mixing, hot-melting and tabletting of raw rubber .
The main working parts are two oppositely inwardly rotating hollow rollers or drilling rollers. The device is called the front roller on the operator's side. It can be moved back and forth horizontally by manual or electrical action to adjust the roller distance to meet the operating requirements. The rear roller is fixed and cannot be moved back and forth. The two rollers are generally the same size and each rotates at different speeds. The raw rubber or rubber material is rolled into the gap between the two rollers with the rotation of the rollers, and is strongly sheared to achieve the purpose of plasticizing or mixing. Open mills are also used in plastic processing.
又都习惯称它为两辊机。 In plastic products factories, people are used to calling it a two-roller machine. Opening mill is a kind of mixing plastic equipment which is applied earlier in plastic product manufacturing plants. In the calender production line, the role of the open mill before the calender and after the mixer is to mix and plasticize the uniformly mixed raw materials to provide a more homogeneous melt for the calendering and molding of plastic products. In the production of cable materials, the open mill can directly mold the powdered material mixed according to the formula into a molten material, and then press-mold it into a sheet belt to cut the pelletizer into granules.
In the floor leather production line, it can directly provide the base coat for mixing and plasticizing for bucky leather.

Opening mill has simple structure, easy operation and easy maintenance, so it is widely used in plastic products enterprises. During the operation, the workers need to manually knead and turn the kneaded materials, and the number of times of manually turning and kneading the plastic pieces has a greater impact on the quality of the raw material kneading.
▌Open mill equipment advantages, structural characteristics Mixing mill equipment advantages, structure characteristic / Mixing mill equipment advantages, structure characteristic
1. Roller: The roller is made of cold hard alloy cast iron (condensed cast iron penetrates the hard alloy layer). The hardness of the cold hard layer on the surface of the roller can reach 7 ± 2HSD, and the depth of the cold hard layer is 8 ~ 22mm.
2. Roller bearings and seals: Rolling radial bearings can be used to save 5-8% of power. Both ends of the bearings are sealed with a fully closed aluminum shell stopper seal, replacing the traditional semi-circular pressure ring seal, which effectively prevents oil leakage and Compact and beautiful structure, compared with other manufacturers adopting bearing bush drive equipment, the operation is more stable, more durable, and the operation noise is lower
3.Roller bearing lubrication: including manual dry oil pump, electric dry oil pump, or thin oil lubrication
4 bearing seat: made of cast steel, annealed and processed, with lubricant
5. Distance adjustment device: divided into manual distance adjustment, electric distance adjustment, hydraulic distance adjustment, the user chooses the rubber baffle according to the requirements of the rubber mixing process: divided into fixed, manual mobile, hydraulic mobile,
7.Transmission method: Divided into single drive single output shaft, single drive double output shaft, and double drive, reducer SYF355-45-11 hard tooth surface reducer, oil bath lubrication system; reducer is hard tooth surface reducer Low noise, long service life and high transmission efficiency
8-roller temperature adjustment device: The cooling system is a rotary joint type, which improves the cooling water circulation work. An intelligent temperature control system can also be used to control the temperature.
9.Optional glue turning device, saving manpower, improving work efficiency, using hydraulic glue turning
10.Integral base: seamless welding of high-strength H-shaped steel, high structural stability, integral cast frame, no deformation, no cracking
11. Motor YS280S-6 class 55kw has strong power, stable operation without noise, high transmission efficiency, high accuracy, power saving, smoother operation and long service life.
12. The braking is controlled by the electrical cabinet for emergency stop, and the 1/4 working surface is automatically reversed. The safety performance is greatly improved. The equipment is equipped with overload protection devices to protect the main parts from being damaged due to overload. Machine can be braked immediately in case of emergency, safe and reliable

Check the rubber material before feeding to prevent mixing with hard metal debris. Put the rubber into the mixer with the rubber, which will cause a sudden increase in lateral pressure and easily cause equipment damage.
/ Mixing mill using the operating specifications Mixing mill using the operating specifications
First of all, it is necessary to adjust the roller distance and maintain the balance of the roller distance. If the rollers at both ends have different adjustments, the rollers will be eccentrically loaded and the equipment will be easily damaged. This is strictly prohibited.
After the work is completed, cut off the power and close the water and steam valves.
In addition to the above, also note:
Pay attention to the surrounding conditions when pulling and pushing the vehicle, to prevent collisions and bumps, and to prevent overturning and hurting people when loading.
The equipment is equipped with emergency braking, and the machine can be braked immediately in case of emergency, safe and reliable.
The roller distance adjustment method can choose electric distance adjustment, which is more convenient to operate than manual distance adjustment.
