Highly corrosive bulk materials require the use of corrosion-resistant alloys in the construction of screw conveyors. These conveyors are essential in various industries for the efficient handling and transportation of materials in bulk. The material of construction plays a crucial role in ensuring the longevity and performance of the screw conveyor, especially when dealing with corrosive substances. Let's explore the different aspects of screw conveyor material of construction and the considerations involved in selecting the right materials.
Abrasive bulk materials may cause excessive wear of screw conveyor components. Screw conveyors must be fabricated from abrasion resistant alloys. Typical materials of construction are AR235, AR400, AR500, TriBraze or chromium carbide overlay. These materials are harder and tougher than A36 carbon steel
Schematic Diagram of Screw Conveyor
A screw conveyor is a versatile and efficient mechanical conveying device that moves materials in a controlled manner. The schematic diagram of a screw conveyor typically consists of a helical screw blade, shaft, housing, bearings, and drive mechanism. The helical screw blade is responsible for moving the material along the conveyor length, while the housing encloses the screw and provides support. Bearings help in smooth rotation, and the drive mechanism powers the conveyor system.
Screw Conveyor Definition
A screw conveyor is a bulk material handling equipment that uses a rotating helical screw blade to move materials horizontally or at a slight incline. It is widely used in industries such as agriculture, food processing, mining, and construction to transport various types of materials, including powders, granules, and flakes. Screw conveyors are known for their efficiency, reliability, and versatility in handling a wide range of bulk materials.
Martin's Pocket Screw Conveyor Instructions
Martin's Pocket Screw Conveyor is a compact and portable screw conveyor designed for easy transportation and setup. These screw conveyors are ideal for temporary or mobile applications where a traditional conveyor system may not be feasible. The instructions for setting up Martin's Pocket Screw Conveyor are straightforward and user-friendly, making it a convenient solution for temporary material handling needs.
Screw Conveyor Specifications
When selecting a screw conveyor for a specific application, several specifications need to be considered. These include the conveyor capacity, length, diameter, pitch, speed, material of construction, motor power, and discharge height. The specifications of a screw conveyor determine its performance, efficiency, and suitability for handling specific bulk materials. It is essential to carefully review and adhere to the specifications to ensure optimal operation of the conveyor system.
Auger vs. Screw Conveyor
Augers and screw conveyors are both used for moving materials, but they differ in design and application. Augers typically have a larger diameter and are used for digging or drilling purposes, such as in agriculture or construction. On the other hand, screw conveyors have a narrower diameter and are specifically designed for bulk material handling applications. Screw conveyors are more versatile and efficient in transporting various types of materials over longer distances.
Screw Conveyor Trough Liners
Trough liners are commonly used in screw conveyors to protect the trough surface from wear and corrosion. These liners are typically made from materials such as UHMW (Ultra-High Molecular Weight) polyethylene, stainless steel, or rubber, depending on the application requirements. Trough liners help extend the lifespan of the screw conveyor by reducing friction and preventing damage to the trough surface caused by abrasive materials.
Parts of a Screw Conveyor
A screw conveyor consists of several key parts that work together to facilitate the movement of materials. These parts include the inlet and outlet, trough, screw blade, shaft, bearings, drive unit, and support legs. The inlet serves as the entry point for materials, while the outlet allows for their discharge. The trough houses the screw blade, which is responsible for moving the materials. The shaft connects the screw blade to the drive unit, supported by bearings for smooth operation.
Screw Conveyor Working Principle
Highly corrosive bulk materials require the use of corrosion resistant alloys. Screw conveyors must be fabricated from alloys not affected by the corrosive product. Typical materials of
All MIGS screens are manufactured in accordance to the API RP 13C (ISO 13501) standards and have been tested independently by an external 3 rd party laboratory to ensure the results are impartial. API screen testing standards are comparable to other screen manufacturers by using a standardized method of determining cut point and conductance.
