According to new type it may be more economical and reliable. Before this the bucket conveyors were used to transport the materials resulting in many problems like time consuming and maintenance. With the help of this pipe conveyor this problems will be solved. The bulk material conveying technology, a powerful and highly specialized field of the conveying technology, is characterized by its distinctive technical variety. Currently the development of conveyors is trying for reliable operation and efficiently economic. The users of pipe conveyers and producers face a very interesting problem of interaction of pipe conveyor belt with molding rolls. There are created high resistances and deformations in this part of pipe conveyor. The determination of contact forces is difficult. In pipe conveyor when the belt is transformed flat into tubular form it may arise the problems but the correct material of belt can solve it.

In the process or manufacturing industry, raw materials need to be transported from one manufacturing stage to another. Material handling equipment are designed such that they facilitate easy, cheap, fast and safe loading and unloading with least human interference. For instance, belt conveyor system can be employed for easy handling of materials beyond human capacity in terms of weight and height.

For handling of partial or continuous goods, belt conveyors are very efficient way. Belt conveyors are used in mining, iron and steel plants, thermal power plants, ore, coal, limestone, sinter transmission, automotive and the other sectors. There are several factors that have to be taken into consideration when a belt conveyor being designed. That means belt conveyor design process requires repetitive strength calculations. But analytical calculations are not capable of determine to entire stresses which occured at whole body. During the design process, time can be saved with the assistance of Finite Element Method. In this study; as a result, it has been seen that, F.E.M is the most practical method which can be utilized during belt conveyor design process.

The Foundry sector is having very wide use of Belt Conveyor. Belt conveyor is used to transport material from one location to another. Belt Conveyor is a widely used continuous transport device, it has a high performance, wide conveying capability and it can be done at various distances, various transport of materials. The task of transportation within the conveyor belt systems can be defined as a process aimed at the transportation of the determined quantity of handled material within a defined period of time between the specified loading and unloading locations. It is significant to reduce the energy consumption or energy cost of material handling sector. This task accordingly depends on the improvement of the energy efficiency of belt conveyors, as these are the main energy consuming components of material handling systems. In this project the solution on more weight and power consumption is given. Hence in this project we are going to design and optimise the critical parts of roller belt conveyor used in Foundry, i.e., roller, bracket, bearing, and frame of conveyor.

This document provides a detailed summary of the design & analysis of the Heavy-Duty Overhead Conveyor system. The task at hand is to Manufacture an overhead conveyor systems system that can carry a maximum payload of 100 kg which can be used instead of the current conveyor system having a payload of 50kg to make the system cost-effective as well as credible as per market requirements.

The basic aim of this Paper has been conducted on the most of the time conveyor chain is under tension which causes failure of chain assembly which is the major problem for industrial sector. Causes of this failure are improper design. It is important to study the influence of these parameters. All these parameters can be considered simultaneously and chain link design optimally. Optimization is the process of obtaining the best result under given circumstances in design of system. In optimization process we can find the conditions that give the maximum and minimum value of function. In this study a shape optimization process is used for the design of roller chain link for minimization of failure modes. This process various design variables, such as wall thickness of link, breaking area of link and shape of the link. While deciding the shape optimization of roller chain link raw material plays important role, so it is necessary to decide new material and Design the new chain with Suitable Design Process.

Conveyor structure is a tool that is applied to the mining industry as a tool that supports the process of moving excavated materials such as coal. The structure of the conveyor is made of steel which is subject to corrosion. The disadvantage of corrosion is that it results in a reduction in the thickness of the conveyor structure. Therefore, it is necessary to control and monitor corrosion on the conveyor structure to be observed, so that corrosion can be controlled. The purpose of this study was to determine the type of corrosion, corrosion control methods, and thickness reduction. The methodology used in this study is measuring the thickness reduction of the conveyor structure. This research was conducted on a 60 meter long conveyor structure above ground level. Measurement of the thickness of the conveyor structure using the Ultrasonic Thickness Gauge TT 130 at 16 observation points. The environmental conditions in the research area are the air temperature in the range of 27oC-29oC, while the rainfall is in the range of 111.37-437.30 mm. The type of corrosion that occurs in the conveyor structure is uniform corrosion. In controlling this corrosion using a 3-layer coating method with a Seaguard 5000 primer coating, Sherglass FF intermediate coating, and aliphatic acrylic modified polyurethane top coating.

Warehouses are large plain and commercial buildings used for storage of goods by manufacturers, importers, exporters, wholesalers, transport businesses, customs department. Earlier days unloading, stacking and loading operations were being done manually, which requires a huge number of porters to handle the material. For the last few decades, people are using fork lifts, conveyors and Hook Cranes to perform the unloading, staking and loading operations. Conventionally, these forklifts are powered by I. C. Engines which emit exhaust gases inside the warehouses. So, in order to overcome such drawbacks, D. C. motor driven forklifts were developed. But they cannot be used for heavy loads. They also require large turning radius / moving space. The technical solution that is deemed feasible and capable of addressing the above mentioned issues is an electrically operated overhead travelling cargo handling machine which reduces the turning radius and increases the storage area. In this overhead travelling forklift, we have a column to which the fork is attached. This column can move along the long travel and cross travel with ease. In this we use a bevel gear which helps us in slewing of fork. The fork lift with the help of AC motor instead of DC motors and I. C engines, which require refueling or recharging time. As a part of our project dissertation, we are making " Overhead travelling cargo handling machine for warehouses " which might be helpful in the reduction of exhaust emissions from forklift exhaust in warehouse as it operates with electric energy. The main objective of this project work is to study the physical properties, optimum parameters of the process and the working rate of existing techniques of material handling (Cargo handling) and develop a design approach to provide a better working environment to the workers working in warehouses and subsequently increase the storage space.

Stress on shaft comes out to be 13.17 MPa.

Over the years a lot of work has done and is still continuing with great effort to save weight and cost of applications. The current trend is to provide weight/cost effective products which meet the stringent requirements. The belt conveyor is an endless belt moving over two end pulleys at fixed positions and used for transporting material horizontally or at an incline up or down. Allow quick and efficient transportation for a wide variety of materials. Diverter car belt conveyors are used to transfer concrete horizontally and limited distance vertically. They are particularly useful in areas such as dam slabs where it is difficulty to put concrete at mid side of the river at specific point, bridge, tunnels where space is limited and where it is difficulty to put concrete at specific point, Bridge grader making. A 25 meter cantilever belt conveyor is used in the diverter car belt conveyor system. The supporting the belt conveyor system is called belt conveyor supporting structure. Structure that supports and maintains the alignments of the idlers and pulleys a nd support the driving machinery. Goal of the project is to study existing conveyor system and optimize dead weight, structures optimize to minimize the overall weight of assembly and material saving can withstand such loads. The design of supporting structure can be make safe. With the help of SOLIDWORK for modeling and ANSYS 14.5 for analysis we analyzed the whole system.
