零基础学绘画INTRODUCTION
Belt conveyors have been ud for over 150 years. The concept of conveying bulk solid materials by belt, however, has not really changed. Most rearch has been focud on the improvement of conveyor components and on the optimization of the belt’s reinforcement material and rubber compounds. Today however, one can differentiate between open and clod conveyor systems. In conventional open belt conveyor systems the belt is troughed and the bulk solid material is in direct contact with the air, (although the total conveyor may be enclod). In clod conveyor systems, the belt contains the bulk material, thus eliminating the risk of dust contamination.

This paper will discuss the state-of-the-art in clod belt conveyor system design, and will highlight the most important differences between open and clod belt conveyor systems. The following topics will be discusd:
∙conveyor belt design and construction requirements,
∙菜市场独门生意conveyor suitability,
∙conveyor loading and unloading procedures and systems,
搬家有什么讲究和忌讳∙conveyor geometry in particular the design of horizontal and vertical curves,
∙conveyor structure design,
∙conveyor drive systems, in particular the energy consumption,
∙environmental impact of belt conveyors.
工资标准The characteristics of a conventional belt conveyor will be compared with tho of both the pouched and pipe conveyor to discuss the above mentioned topics. The figures 1, 2, & 3 show the basic construction of the two clod belt conveyor concepts. Although the figures 1 and 2 depict the same principal of pouch conveyors, there are fundamental differences relating to the belt construction and drive techniques, as will be explained in ction 2.

CONVEYOR BELT DESIGN AND CONSTRUCTION REQUIREMENTS
The main difference between the three belt concepts mentioned in the introduction is the construction of the belt. This ction discuss typical belt constructions.
我的暴龙老爸Conventional Conveyor Belt
Conventional conveyor belting has developed over the years and today operates at tensions as high as 1000 kN/m (or N/mm) width. Their construction can be full fabric, steel cable or steel matrix, a combination of the steel and fabric, or even a monoply fabric construction. Typical carcass ctions are shown in figures.

Pouch Type Conveyor Belt
The two pouch belt options differ in their appearance by the construction of the tension number, with the Sicon using a steel cable tension member offering a typical rope tension of 10 kN and the Enerka-Becker System (EBS) being a total fabric/rubber construction having a maximum operating tension of about 10 N/mm.
The basic difference between the two systems are:
∙The axial profiles of the EBS belt have no reinforcement, the axial profiles of the SICON belt have a steel cord inside.
∙The main body of the SICON belt has no reinforcement whereas the main body of the EBS belt includes fabric reinforcement.
∙The axial profiles of the EBS belt and the belt’s rubber cover form one piece. The axial profiles of the SICON belt and the main body of the belt are two pieces (warm) vulcanized together.More information on pouch belt conveyors can be found in [1].
Pipe Conveyor Belt
The pipe conveyor belt is bad on the construction of the conventional belt conveyor. Both fabric and as well as steel reinforcing can be ud. However there are subtle differences between the two concepts.
