Today the air-swept vertical roller mill is the standard solution for coal grinding installations. And thanks to our contin-uous refinement of the ATOX coal mill over the years, today’s leading air-swept vertical roller mill is the compact ATOX. Offering high reliability,
Vertical roller mill (VRM) is a large-scale grinding equipment, which is used to grind raw materials from block/granule into powder. Due to harsh production environment and inconsistent raw
Prepare a graph with motor torque on the horizontal axis, motor speed on the left vertical axis, and motor current on the right vertical axis. Scale the axes based on the measurements in step 1. Draw a straight line from the left origin of the graph (zero torque and zero current) to the stall current on the right vertical
•Existing design calculation shows the factor of safety is very greater than requirement and there is a scope for weight reduction. •Critical parameter which reduces the weight is C-channels, roller outer diameter and roller thickness. •Though value of deflection, stress is more in case of Optimized design, but it is allowable.

Motor Sizing Calculations This section describes certain items that must be calculated to find the optimum motor for a particular application. Selection procedures and examples are given. Selection Procedure First, determine certain features of the design, such as drive mechanism, rough dimensions, distances moved, and positioning period.

Roller Chain Drive Design • Drive Ratio Roller Chain operates at high efficiency on drives with reduction ratios up to 3:1, but can be used effectively for drives up to 5:1 reduction. Higher ratios are not recommended but on some very slow speed drives reductions up to 10:1 have been used. High

The aim of this thesis is to provide a general overview on the design and engineering of roller coaster layouts, structures and attached functions. This thesis is a collaboration with Linnanmäki  and was initiated when a large-scale roller coaster project entered planning phase, and various design methods and criteria needed to be studied.
A slot design without the steel U-shaped slot is possible. This requires the rails and seal contact surface to be mounted and grouted in a slot cast in concrete. This is very work intensive and does not result in the quality roller gate system that the complete fabricated slot system provides. Figure 8-1 Fabricated Roller Slot with Double Rails

The goal of the study is to design the hydraulic scissors lift to lift up to a height of 1.2 meters and with the carrying capacity of 700 kilograms. The driving mechanism of the lift must be a hydraulic cylinder. Calculations of the inner stresses must be done and a 3D model must be created. It is also necessary to choose the material.
