Screw conveyor auger conveyor systems Overview

An economic analysis of the usual method is to install the system in comparison with the total cost, and then the system running costs for the comparison. A system including the equipment for the operation of the system of electricity, operating and maintenance manual, spare parts and other parts costs have a direct impact on the running system.
Using this method provides decision makers with the two most important economic indicators, but does not include some of the other important indicators in May, for example, whether the device after running the system fully functional, have a long life. In a typical enterprise, as most of the national matters for businesses, which may be a purchase decision, that decision makers have accepted metrics. However, it is better suited for a more effective economic comparison of analytical methods for pneumatic conveying system. This method is called a cycle cost analysis method of pneumatic conveying systems.
As a scientific comparison of the methods is bound to influence the system of investor decisions. For investors, if its investment in the course of the operation of the system in the future may not bring good economic benefits for him, but what’s with this investment decision is a mistake.
First System Overview
screw conveyor design system is a mobile gas than the average powder materials (ASH) of transport of one or more transmission to one or more parts of the process. General program of pneumatic conveying system in a variety of designs, engineering designs of various major systems as required by the investor.
Conceptually, all of the powder material is pneumatic conveying system pressure or low pressure gas transmission network as a transmission medium through the pipeline system is applied. Air is the most commonly used gas transport, but it can not be used to transfer reactivity of materials. Transport media and transport of materials allowed in any mixing ratio. Two of the most extreme type of gas-solid mix a powder that is only in a separate compressed air line transmission in other cases, such as solid powder material, No stream or gas do not mix. The conveyor system can be designed for the choice of a mixture between the two extremes. Designer designs are suitable under different conditions pneumatic conveying system for this kind of material properties, comparative economic pneumatic conveying systems.
Material properties are the key to what kind of support system. This may encourage a comparison of the wet cement and coal, that system is very easy to understand. Although this type of materials may pneumatic conveyors, pneumatic conveying system of the former and the latter are very different. For this reason refers to the properties of these materials and how these properties into the pneumatic conveying systems interaction. For example, can use the cement powder is easily mixed with air, easily fluidization. High-speed transport, characteristic of this material will not be altered and wet coal, on the contrary, they make it difficult to stream only with high-pressure, high flow of gas to be “boiling”, but the properties of the original material was destroyed. Pipeline transport of materials have different properties can be selected in different materials in different conveying speeds.
Many materials have very good abrasive, such as with a good grinding of cement powder, is high-speed transmission strong and take the lead while carrying the switching system of valves and other devices at the same time also.
In addition, the consumption of electrical energy is also an important cost factor obviously. System of the gas pressure compressed air consumption, transmission, transmission range, can affect productivity, and impacts on electricity consumption.
Each design of a conveyor system is made up of many of the design elements can, and every design element has several variants, which have many styles, seems to be a particular need, but if you must select appropriate valuation method for their performance and cost, the optimal to find design.
Second Twisted Dragon handling
(1) the diluted system
Dilute the operating pressure of the system is lower than 0.1mA, this system uses a gas which attachment blocking imported as physical equipment. Diluted system is usually the typical rotary valve, pipe, abrasion-resistant elbow dust remover or storm and wind and other components.
The system provides, as it is the material of the original property, which can damage a mixture of very high transmission speeds and lower at the same time on the wear of the pipes is also very serious. In pneumatic conveying systems, the diluted system is usually the lowest initial investment.
(2) screw conveyor design the dense-phase system
Dense-phase system operating pressure is higher than the 0.1mA, which usually requires a pressure vessel, make promote air pressure system and fully mixed and then imported. In general, the dense-phase system is divided into two basic types:
A. no fluidization system. In general, the system is equipped with a small pressure tank, this system does not allow compressed air pressure in the container and materials in pipeline or “cooking”. It is characterized by the transfer speed is very low to keep the original characteristic of the material better and pipe wear is minimal, but the higher initial investment than the above two systems.

As fluidized bed systems. This type of system has a large pressure vessel used in the feeding control valve, to the loading of material and pressure to control vessel, and a streaming device, valve, and so on. When a mixture of compressed air and materials upon import routed to the destination. Higher transmission speed of this system, but is much lower than that of the diluted system. Likewise, material removal and less wear of the pipes.
