Merchandise Description

Rubber wrapping drum is an essential part and element of belt conveying technique. The rubber wrapping of the drum can properly enhance the operation condition of the conveying program, shield the metal drum from wear, stop the slip of the conveyor belt, and make the drum operate synchronously with the belt, so as to guarantee the successful and huge quantity procedure of the belt. The rubber coating of the drum can also successfully stop the sliding friction in between the drum and the belt, reduce the material bonding on the drum floor, and minimize the deviation and wear of the belt. Broadly used in: Iron and steel, metallurgy, coal, cement, electrical power era, chemical fertilizer, CZPT depot, port and other industries.

Coating materials

Organic rubber, nitrile rubber, neoprene, EPDM, polyurethane, and many others. can be utilized.

technological innovation

There are 2 kinds of rubber wrapping roller technological innovation. The traditional rubber wrapping technological innovation, this kind of as sizzling vulcanization technology, mostly vulcanizes its rubber with the roller via the vulcanization tank to make certain the bonding power among the rubber wrapping panel and the roller. The second is cold vulcanization technological innovation, which employs a unique chilly vulcanization technique to immediately bond its roller with the rubber wrapping panel, which can be utilised for on-web site rubber wrapping, underground rubber wrapping, etc, Its technologies is far more innovative, but also drastically decreases the labor value.

Producing procedure: generally, in phrases of the main shaft of the drum, it can be divided into the following 2 sorts according to the load: (1) the mandrel only bears bending second, such as the shaft of the drum group (2) The CZPT shaft bears bending moment and torque at the exact same time, this kind of as the shaft of the transmission drum group The substance of the shaft is typically rolled or cast carbon steel or alloy metal. The usual substance is medium carbon metal. No. 45 steel is the most frequently utilised. For the shaft with huge tension and constrained dimension, and some shafts with particular demands, alloy steel can be utilised. The content is forty chromium. According to the wants, the shaft normally requirements warmth treatment method or floor strengthening remedy, In order to improve its mechanical qualities and put on resistance, the big difference of elastic modulus amongst alloy steel and carbon metal is very little at standard temperature, so the use of alloy metal can not improve the stiffness of the shaft The shaft content is usually matter to quenching and tempering therapy. For the transmission drum team, when the shaft toughness index does not fulfill the needs, it can also be mixed and quenched and tempered, and checked in accordance to the allowable anxiety of symmetrical circular bending The technical specifications for shell layout are: (1) when the shell is curled, it must stick to the rolling course of the steel plate (2) The misalignment at the joint shall not be better than 1mm (3) Ultrasonic or X-ray flaw detection must be carried out for the longitudinal weld soon after the drum is coated with glue: ultrasonic flaw detection shall be carried out for 10%, and the weld shall reach quality II in the regular Radiographic flaw detection starts from 1 end and detects twenty% of the whole size. The weld reaches grade II of the countrywide normal. If the flaw detection size is doubled and even now unqualified, entire-length flaw detection shall be carried out till it fulfills the needs (4) The roundness tolerance of the rolled shell shall not CZPT .5 (5) Materials: Q235 area metal with yield strength of 235 n / m2 For medium-sized drum group and light-responsibility drum group, when the outer diameter of the hub is higher than 220mm, cast steel shall be utilised. For mild-responsibility drum group, when the outer diameter of the hub is less than 220mm, very hot-rolled spherical steel shall be used, which shall meet up with the national standard.


A movable pulley is a pulley exactly where when you transfer a hefty item, the drum moves with it. There is no adjust in the course of the force you want to apply, but the load will “really feel” lighter than it truly is. For case in point, if you are hauling a hefty hay bale up the barn’s attic, a moveable pulley will make the load truly feel a great deal lighter, even although you’re pulling in the identical direction.
In a compound pulley technique, there is the two a movable pulley and a fastened pulley. This implies that not only does the load “really feel” lighter, but you can also alter the path of the power. While this sort of configuration can go weighty masses extremely effortlessly, it comes at the price of requiring really a little bit of motion to do the work.
