screw conveyors are one of the most reliable and cost effective methods for conveying bulk materials. due to their versatility screw conveyors can convey a wide variety of bulk materials ranging from dry free flowing portland cement to wet sluggish dewatered biosolids.
vibra screw incorporated was founded in 1955 by eugene a. wahl whose experience in solving problems in the process industries led to revolutionary ways to discharge and meter dry solids. today with a staff of experienced and talented engineers and technicians vibra screw is the leader in solids processing with high quality equipment to store discharge meter convey size and blend.
the kws shaftless screw conveyor design prevents sticky sludge build up. the complete conveyor housings were constructed from 304 stainless steel for corrosion resistance. the drive shafts for the kws shaftless screw conveyors were machined from a single piece of bar stock to eliminate a
flexible screw conveyor also known as a spiral conveyors screw conveyors helix conveyor or centerless auger conveyors consists of a spring steel or stainless steel flexible screw that is enclosed in a flexible or rigid plastic tube or a rigid steel tube and driven by an electric motor normally located at the discharge end of the conveyors.
in use advantages. nbe offers a full line of solid core screw conveyor designs to ensure safe automated material transfer of dry bulk goods. whether conveying bulk material from offline storage to an inline operation or conveying dry free flowing material from one stage of processing to another integrating nbe screw conveyors into new

a shafted screw conveyor is a screw conveyor that has a solid shaft that goes through the flighting of the screw. this helps hold the flighting off of the bottom of the trough. pros of a shafted screw conveyor a shafted screw conveyor can be a longer length. in most applications the shafted screw conveyor uses hanger bearings every 10 12 feet.
flexible screw conveyors or auger conveyors are often the lowest cost means of transferring dry bulk solids from one point to another. gentle product handling the rotating flexible screw conveyor spiral centralized within the conveying tube gently moves material without degrading it.
apr 15 2014018332mechanical conveying of bulk solids. other widely employed mechanical conveyors include screw conveyors drag chain conveyors and bucket elevators. furthermore a choice often needs to be made between mechanical and pneumatic conveying the latter involving a selection of lean dense phase or slug type conveying.
shaftless screw conveyors this project is an environmental friendly solution that eliminates disposal costs. we paired up a spiropress 174 with a spirotainer 174
post separation from liquids solids are often conveyed using shaftless 304ss screws which are a very good fit for sticky gritty wet materials. inclined screw conveyors are also often employed to move materials to elevated areas.
features amp integration guide. nbe flexible screw conveyor hoppers are designed with a flangeless conveyor intake that ensures consistent infeed of material to the flexible screw conveyor eliminating the bridging ratholing and sporadic material supply common with flange style designs.
kws shaftless screw conveyors are successfully used throughout the chemical food minerals processing and wastewater treatment industries for conveying everything from catalysts to dewatered biosolids. kws developed the industry standards for shaftless screw conveyors and continues to create new and improved design standards.
gn screw conveyor features amp benefits gn solids utilize a custom designed and constructed screw conveyor (auger) as part of drilling waste management system.the auger is designed with 12 feet per section which makes it to be standard spare parts for exchange with each other.the screw material utilized by gn is abrasive material which lasts longer than our competitors.
a vertical screw conveyor conveys material upward in a vertical path. it requires less space than some other types of elevating conveyors. vertical screw conveyor can handle most of the bulk materials provided there is no large lump. the maximum height is usually limited to 30m.
bulk solids conveying wamgroup has come to stand for innovation in bulk solids conveying technology and equipment tailored for a number of applications in various industries.as the worlds leading manufacturer of screw conveyors wamgroup also boasts vast know how and expertise in bucket elevator and chain (drag) conveyor technology.
flexible screw conveyors flexible screw conveyors handle virtually any bulk solid material. depending on model conveyor tubes can be curved around over or under obstructions and routed through small holes in walls or ceilings.
screw conveyor safety begins with a plan that considers every possible danger and potential hazard. operation and maintenance personnel must be thoroughly trained in safe operating procedures recognition of possible hazards and maintenance of a safe area around screw conveyors.
equipment design. belt conveyors are usually flat but in bulk solids handling they are typically troughed to prevent material from falling. belt conveyors are driven at one end by a motor not shown that rotates the drum to move the belt. at the other end of the conveyor there is an idle drum.

screw conveyors in modern industry are often used horizontally or at a slight incline as an efficient way to move semi solid materials including food waste wood chips aggregates cereal grains animal feed boiler ash meat and bone meal municipal solid waste and many others.
pneumatic conveyor systemspneumatic conveyors use pressure differences and airflow to move goods down an assembly line. these systems can save you energy and money during your packaging process. screw conveyorswhen working with granular products rely on a screw conveyor
screw conveyors are a very popular equipment in solids processing industry to move and / or dose products. their principle allows a simple and quite robust operation although the design must be well detailed in order to avoid issues that could lead to damages to the product and to the equipment itself (generation of foreign bodies).
municipal water and waste water treatment plants need to use conveyance for solids screenings and grit. plants choose between belt conveyors and screw conveyors. the choice between belt conveyors vs screw conveyors comes down to what materials you are conveying. because municipal water and waste water treatment applications have several difficult to handle products we
