It is with great pleasure that Continental presents this Screw Conveyor Catalogue and Engineering Manual which covers our complete line of screw conveyors and accessories. The information compiled in this manual is the result of many years' experience in the design and manufacture of bulk material handling equipment and is thereby your assurance of the best in both equipment and recommendations. With the help of this manual, the screw conveyor user is given sufficient design information with which to effectuate a sound selection of both single components and complete screw conveyors alike. All Continental screw conveyors and components are designed and built in accordance with the standards established by the industry and are therefore completely interchangeable with equipment of other recognized manufacturers. Continental's production facilities have also kept pace with inherent advancements in design. Numerous specialty machines have been designed and methods have been devised that help assure and control manufacturing tolerances, thus providing for interchangeability of parts, greater ease of assembly, smoother operation and longer life. We sincerely hope that you will find this manual complete in detail, easy to use and extremely helpful in fulfilling your screw conveyor requirements.

FOREWORD The basic principle of the screw conveyor remains unchanged today from when Archimedes first used an internal type helix to remove water from the hold of a ship. With the technological innovations of the past cen.tury and a great deal of research in the field, screw (::onveyors have become precision pieces of equipment that can move materials either horizontally, on an incline or vertically. They can be used as feeders, distributors, collectors or mixers and can be equipped to either heat or cool while performing the task. With proper covers and gasketing they become weatherproof, dust tight and rodent proof. Their compact design allows them to fit easily into restricted areas that would otherwise be unsuitable for most types of bulk material handling equipment. They are simple to install and support and require very little maintenance. Per foot, they are undoubtedly one of the most economical types of bulk material handling equipment available today.

The following section contains all relevant information and basic engineering data that is required for specifying and designing the important features of most screw conveyor installations and applications. There will, however, be instances when the information herein will be insufficient with which to effectuate proper design due to uncommon variables that may be present. Continental staff and engineers have considerable knowledge in the design of screw conveyors for special applications and will gladly assist you with sound suggestions and recommendations for your particular problem.

Material Analysis The initial step in engineering a screw conveyor is to analyse the material being handled and ascertain its physical properties in order that they may be thoroughly evaluated and understood prior to proceeding with the conveyor sizing and selection. These properties are discussed in further depth below.

Lump Size: The minimum diameter of a conveyor screw for a given application is determined by the maximum lump size of the material being handled. For this reason, it is necessary to thoroughly analyse the material and determine its maximum lump size and the percentage of lumps to total volume along with the minimum particle size and screen analysis when possible. With this information, proper conveyor sizing can be effectuated.

Flowability: The flowability of a material greatly affects the horsepower requirement of the conveyor in question. Flowability is related to the angle of repose of a material and therefore, fine free flowing materials can be handled at higher trough loadings with lower horsepower requirements than coarse, sluggish ones. Please refer to the Classification Code, Table 1 for further information.

Abrasiveness: The more abrasive the material being handled, the greater the wear the conveyor components are subjected to. For this reason, it is necessary to determine the abrasive quality of the material in question prior to sizing the conveyor. Abrasiveness can be determined by knowing a material's hardness on a Moh's scale and should this not be available the material can be compared with another known abrasive material.

Special Applications: These are additional the operation of the conveyor and are further entitled Special Applications and Specifications and 27 inclusive.

factors which can affect discussed in the section appearing on pages 26 '

Moisture Content: Material moisture content is also a factor that affects material flow. Excessively dry or wet products tend to flow easily, however, many develop sluggish characteristics when having a moisture content between the two extremes. This is not accounted for in the material tables which follow and such materials should therefore be reclassified. Duty Cycle: Machinery design also includes selection of the proper equipment for the usage it will receive. A conveyor operating for 2 hours per day does not require the same heavy construction as one designed for 24 hour usage. This appliesto material thickness and drive sizes alike. Likewise. shock loads to which the equipment and drive are subjected to are an important consideration. Treatment of these factors are not described in suitable enough depth here. however, as previously mentioned. our engineering staff will gladly assist you to determine the best conveyor design.
