一、Product overview

The non-metallic idlers developed and produced by our company are made of ultra-high molecular weight polyethylene idlers, which are composed of ultra-high molecular weight polyethylene tubes, bearings and sealing assembly shafts. It has the advantages of lightweight, wear-resisting, non-adhesive material, low friction coefficient and self lubrication of the belt. Ultrahigh molecular weight polyethylene roller can prolong the service life of equipment, save energy and effectively improve the working environment. Widely used in open air dust, high corrosive environment, such as mining metallurgy, electric power, cement, coal, chemical and port industries. It is the ideal replacement product of steel idler for belt transport machinery.

二、Scope of application

Ultra-high molecular roller is widely used in the open air dust, high corrosion environment, such as mines, power plants, steel mills, stone factories, cement plants and coking plants, coal washing plants, salt plants, alkali plants, fertilizer plants, docks and other transportation places.

三、Product characteristics

The roller consists of a tube body, a center shaft and a bearing seal. After the front holes at both ends of the tube skin, it is closely connected with the stamping bearing seat. The overall structure has the advantages of light weight, small resistance and good sealing.

High precision: the tube body is made of ultra-high molecular engineering plastic, high coaxiality, high roundness, high straightness and even wall thickness.

Long life: under the same conditions, its life is more than twice the standard metal roller.

Light weight: about one-third lighter than the same metal roller, easy handling and installation, greatly reduce labor intensity, shorten maintenance time, improve production efficiency. Non-corrosion and wear resistance: the tube body and bearing seat are made of engineering plastics of ultra-high molecular plastic tube body with high strength wear resistance and corrosion resistance, so it is wear-resistant and will not be corroded.

Good sealing: the use of three sealing, water and dust is difficult to overcome.

Environmental protection: In the belt conveyor connected with the belt buckle, the contact noise between the belt buckle and the pipe body is lower than that between the belt buckle and the metal pipe body, so that the working environment is more environmental protection.

Non-wear belt: the surface hardness is slightly higher than the belt and there is no abrasive, in the idler lag working condition, because the tube body is fine for a short time and leave the belt so that the belt is protected.

Energy saving and consumption reduction: the weight of the rotating parts is light, the moment of inertia is half of the standard metal idler, the required driving force is small, the motor starting current is reduced and the braking is easier, each kilometer belt conveyor annual electricity saving tens of thousands to hundreds of thousands of Kw.

Can be recycled: after the failure of the rotating parts, because there is no welding spot in the whole, the roller shaft can be recycled and reused, and other parts can be recycled.

Flame retardant and antistatic: by the national standard center recognized by the testing institution inspection qualified, with flame retardant and antistatic. High safety: it will not wear out the spark with the belt buckle during operation, and it will not produce high temperature from friction with the belt when the roller does not turn due to deformation of the transport frame and other reasons.

四、 The structure of the idler

The roller consists of a tube body, a shaft, a bearing, a circlip, a sealing ring, a bearing base and so on. After the front holes at both ends of the tube body and the bearing seat are pressed together closely, the overall structure has light weight, low resistance and good sealing performance.

(1) The tube body is made of ultra-high molecular weight polyethylene material, which has good toughness, corrosion resistance and wear resistance, ensuring the service life of the idler.

(2) Bearing seat is also made of ultra-high molecular weight polyethylene material, and adopts labyrinth design. It is pressed closely with the tube body to ensure the overall strength of the idler.

(3) The supporting bearing part adopts labyrinth seal, and is closely assembled with bearing seat, retaining ring and supporting roller shaft to form a good protective barrier, which ensures the dust-proof and waterproof performance of the supporting roller and prolongates the service life of the bearing.

The upper roller consists of three rollers, which support the belt to form a trough section for conveying loose materials. Stuck on the frame, you can adjust the position along the length direction of the longitudinal beam tube to adjust the deviation of the upper belt. The larger groove Angle can also improve the transport Angle, so that the cargo can run smoothly. Generally, the groove Angle between 30-35 degrees, according to the need to design the groove Angle can be increased.

The lower roller is used on the belt return section to support the belt. Generally, it is a single long supporting roller, and the supporting roller shaft is a bilateral locally milling flat shaft. The shaft end can be installed in the three notches on the support to adjust the deviation of the return belt. Lower roller support,

六、Product classification

1. Ordinary polymer roller The roller has better performance than the traditional steel roller and the price is the same as steel roller

2. Mute polymer roller Because the roller will produce large noise during operation, which will endanger the health of employees, our company has developed and produced mute roller. Its feature is that there is a sound-absorbing groove on the circumference surface outside the mixer, and the sound-absorbing groove is distributed along the axial interval of the roll body, which better solves the noise problem. The performance of the roller has better noise reduction function and longer service life than the ordinary non-metallic roller, the price is about times higher than the ordinary non-metallic roller.

七、Advantages of polymer roller

1. The operation of ultra-high molecular polyethylene idlers is 25000h-30000h. Flexible rotation, low resistance, no damage to the belt, easy installation, maintenance free. The embodiment of superior performance, but also highlights the performance of ultra high molecular roller, price. In the long run, it can save 50% of the funds.

2. The extension of service life of idlers reduces the number of replacement and maintenance, which not only reduces the labor intensity of staff, but also reduces the maintenance cost of equipment and improves the use efficiency. Users in the process of use can save a lot of manpower, material resources, electricity, so as to bring considerable economic benefits to users.

3. Based on the ultra-high molecular roller long life, excellent cost performance, protection belt, energy saving, easy replacement, environmental protection and many other advantages can improve the transmission power of the conveying machine performance (such as starting motor power can be reduced), and will gradually replace a large area of steel idlers, is the ideal upgrading products.
