Sugar Mill Roller Manufacturers & Suppliers in India

The roller sugar mill tree is one of the most important parts of the sugar mill industry. This is because they are used for the separation of juice containing sucrose from sugar cane. This juice extraction is achieved by squeezing the prepared cone through two rollers. It is for this criticality and importance that it requires careful production and testing in order to meet all the stringent requirements in order to be used in environments of continuous wear and fatigue.

Materials used

The material of the sugar mill tree is decided taking into account its strength and rigidity. The conditions under which these trees operate vary over a wide range. This makes it imperative that the bearing material used to make them have certain desirable properties. These include factors such as:

A low melting point and softness

Mechanical resistance

Corrosion resistant

Low elastic modulus

High thermal conductivity

Other economic considerations

However, it is not possible to achieve all of these factors to some desirable extent in a single sugar mill tree, so a compromise must be made regarding some attributes. The commonly used materials are:

White Metal: This term is mainly used for lead and tin based metals, making them highly competitive. They are mostly recommended for applications where the load is not severe. White metals undergo a reduction in fatigue strength as temperature increases, making this reduction a function of thickness. These are not commonly used for sugar mill trees.

Copper-based alloys: These alloys include gun metal, lead bronze, and phosphor bronze. Among them, lead bronze is the cheapest, making it popular for general service bearings. They have a low tendency to seize and have higher fatigue strength to withstand higher temperatures. They are mainly used in the form of a solid single unit. Gun metal is also a relatively inexpensive machine material with good load-bearing properties. They are able to withstand greater loads than lead bronze alloys while having good resistance to corrosion due to sea water. Another metal used is phosphor bronze which is used in heavy loads where high friction and stress are likely to occur.

Aluminum-based alloys

Lubrication

The sugar mill shafts do not have the ability to turn fast enough to promote the formation of a hydrodynamic film of lubricant between the bearing and the pin. Therefore, they require constant hydrostatic lubrication. This is done by providing lubrication to the bearing at the required pressure. Care must be taken to ensure an adequate supply of lubrication under such conditions. This is especially true of the location of the grooves and oil supply holes. Therefore, considering the accurate production standards and testing requirements, the sugar mill trees are considered an important part of this industry. After all, the main reason for the sugar cane industry is to extract the maximum amount of juice per ton / ground cane. This is achieved by ensuring that the right sugar mill tree is used in the right place.

Rolling Mills Cardan Shafts Manufacturers

Rolling Mills Cardan Shafts Manufacturers

In choosing the right cardan shaft for rolling mills, there are several factors that need to be taken into consideration such as the size of the load, the transmission speed, the installation accuracy of the two connecting parts, the rotational stability and the price. The type of joint is chosen based on the other characteristics of the joints.

How to choose the right cardan shaft?

There are a few factors that need to be kept in mind when choosing the right cardan shaft for rolling mills. These are:

Due to several factors such as temperature change, load deformation, manufacturing and installation, it becomes very difficult to keep shafts in accurate alignment after installation. There will certainly be a shift. A sliding joint is selected in cases where the radial displacement is large. Universal shafts are used to connect two axes with large angular intersection or displacement. Flexible couplings are selected in cases where a large additional relative displacement is produced by the two shafts during the work process.

It is also necessary to take into account the centrifugal force caused by the working speed of the coupling. Couplings with high balancing accuracy should be chosen for high speed drive shafts. These include membrane joints and others. There are others such as eccentric slider joints which should be avoided in these cases.

The nature and extent of the torque to be transmitted and the additional requirements for the vibration damping function are also important factors. For example, if the process requires a heavy-duty transmission with high power, then gear couplings should be selected. Tire couplings should be chosen in cases where a severe shock load needs to be transmitted in order to eliminate torsional vibrations of the shaft system.

Basic steps when selecting Shafts

The cardan shafts of the rolling mills must be chosen according to the following steps:

The nature and size of the torque to be transmitted and the requirements for the damping and buffering function are also necessary to make the right choice. For example, gear couplings are chosen in cases where a transmission for heavy loads is required.

It is also necessary to take into account the direction and extent of the relative displacement between the two axes.

The working environment and the reliability of the cardan shaft of the rolling mills also play an important role. Usually, universal joints made of metal without lubrication are quite reliable. However, the performance of the coupling is affected by the perfection of the lubrication, thus polluting the environment. Joints that contain non-metallic elements such as rubber are highly sensitive to corrosive fluid, light and temperature.

For satisfactory performance, couplings with a convenient disassembly and installation process along with low cost and easy maintenance must be selected. For example rigid couplings are not only simple in structure but are also convenient in installation and disassembly.

Cardan shaft rolling mills are available in different types and varieties. Choose the right one from the cardan shaft manufacturers of the nearest rolling mills for trouble-free installation and operation of your machine.

Importance of Cardan Shaft for Rolling Mill

Cardan shafts are known to play an important role in the rolling process. Let's first try to understand what cardan shafts are and then we will discuss their importance.

What are cardan shafts?

Cardan shafts refer to the driveshaft between the rear axle and the gearbox. Acts as a power transmitter to the final drive at the front end of the rear and front frame. Also known as drive shafts, they were originally used in the automotive industry. It includes a telescopic sleeve, two cross joints and a shaft tube. The telescopic sleeve helps in the automatic adjustment of the change of distance between the drive axle and the transmission. In various high-load power transmission processes, certain types of cardan shafts are used for vibration damping, damping and performance improvement of the shaft system.
