Keywords: shaft design, computer aided design, mixer. _____*****_____ I. INTRODUCTION: A concrete mixer is also commonly called a cement mixer, is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete. A typical concrete mixer uses a revolving drum to mix the components.
Nowadays lots of software tools are available in market to take care about the lengthy calculations. Most of the cases a mechanical design engineer only needs to put input and the software tools give the output in desired format. These tools definitely help to drastically reduce the design time. In this article on mechanical design tutorial today I will talk about design of a simple "L ...
Concrete formworks are subjected to various loads and pressure. Concrete formwork loads and pressure calculations are described in this article. Formworks or molds are considerably important for building constrictions by holding fresh concrete mixture at place until it get required strength by which the self weight can be sustained. & Ad Free!

Examples of machine rates for a power saw, a tractor, a team of oxen, and a truck are in the following tables. Although the machine rates in Tables 3.5 to 3.8 share the same general format, there is flexibility to represent costs that are specific to the machine type, particularly in the calculation .
Abstract- In this paper describe the design and calculation of concrete mixer for weight 350 kg approximately. A concrete mixer machine is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete. Concrete is an important component required for construction of houses and roads.
in my country one bag of cement is 50kg or 0.035cum and for measuring aggregates and sand we use head pans(0.0175cum). for 1cum of concrete the expected materials are cement 6.5bags sand; 0.44cum(26headpans) aggregate;0 0.88(51headpahs).but on site we have to use more material to achieve the expected volume instead of the estimated calculations ...

Design calculations are done on the basis of a limiting strain that must not be exceeded. It should be noted that in cases of nonlinear deformation behavior, there is a difference between operating, for example, at 80% of the yield strain and operating at 80% of the yield stress. Different values are obtained as depicted in Figure 5.4.

A floor loading assessment is the evaluation of the concrete subfloor, not the raised floor. However, you should consider the weight of the raised floor in the floor loading formula. Floor Loading Formula. Floor Loading is: (machine weight + (15 lb/ft2 x 0.5 svc clear) + (10 lb/ft2 x total area)/ total area

a. Before starting work on the design of any machine, get thoroughly familiar with what the machine is intended to accomplish and what special requirements or limitations must be considered. b. Make free-hand sketches of various ways the machine might be constructed, at the same time making any preliminary calculations which might be required to
A concrete mixture ratio of 1 part cement, 3 parts sand, and 3 parts aggregate will produce a concrete mix of approximately 3000 psi.. Mixing water with the cement, sand, and stone will form a paste that will bind the materials together until the mix hardens.
