Shafted screw conveyors are used in thousands of industrial applications every day for efficiently conveying a variety of bulk materials. A screw conveyor’s main function is to transfer bulk materials from one process to another. Screw conveyors are very cost-effective and require minimal maintenance to operate.

Bulk materials discharged from centrifuges, filter presses or mixers can easily be metered or conveyed using a shaftless screw conveyor. Our shaftless design provides a non-clogging conveying surface that allows difficult-to-convey materials to become easy-to-convey. The perfect solution for handling bulk materials with high moisture content is the KWS Shaftless Screw Conveyor.

Belt conveyors are the most economical method of transporting bulk materials over both short and long distances. Belt conveyors are ideal for conveying bulk materials of large lump size since the bulk materials stay stationary on the belt. The layout of your plant can be simplified and made more efficient with the use of belt conveyors.

One of the most efficient ways to elevate bulk materials vertically is with a bucket elevator. A Bucket Elevator consists of a series of buckets attached to a belt or chain with pulleys or sprockets located at the top and bottom of the unit. The buckets are located in a casing or housing to contain the material. Bulk materials are loaded into each bucket as the bucket moves past an inlet point. KWS designs and manufactures a wide variety of bucket elevators based on the characteristics of the bulk material and the process requirements.

Vertical screw conveyors are a very efficient method for elevating a variety of bulk materials at very steep inclines or completely vertical. The compact design allows for the vertical screw conveyor to fit into almost any plant layout. With a minimum number of moving parts, the vertical screw conveyor is a cost-effective and dependable component of any bulk material handling process.

Drag conveyors are a great complement to screw conveyors and belt conveyors and a requirement of many bulk material handling applications. Drag conveyors can be used to meter or transfer bulk materials from one process to another. The compact and versatile design allows drag conveyors to fit almost any plant layout.

Screw feeders and live bottoms are one of the most accurate and efficient methods of metering bulk materials. Many processes begin with bulk materials being discharged from hoppers, bins or silos. The inlet area is flood-loaded and designed to meter bulk materials at fixed or variable rates. With our extensive knowledge and experience, KWS will provide a system to meet all of your requirements.

KWS Mass Flow Screw Feeders are the most efficient method to unload bulk materials from a large bin, silo or hopper. The term `mass flow` describes a material flow pattern in which all material in a bin is drawn down at the same rate, regardless if the material is against the sidewall or in the center. The alternative is commonly referred to as `funnel flow`. In a funnel flow situation only the material in one portion of the bin is drawn down.

Many bulk solids processing applications require mixing of solids and liquids under both pressure and temperature to achieve a desired finished product. Pressure or vacuum can be applied to the internal portion of the vessel where the bulk solids are being processed. The bulk solids can be heated or cooled as required by external jackets that are integral to the vessel walls. KWS coded pressure vessels combine our knowledge of conveying and mixing with the science of heat transfer.

Slide gates are used to control the discharge of bulk materials from hoppers, bins, silos or conveyors. Slide Gates consist of a rigid frame mounted to the bottom of a storage device or conveyor. A slide plate is located inside the frame that either opens or closes against the flow of material. The slide plate can be moved by manual, pneumatic, electric or hydraulic means. KWS slide gates are a great complement to our bulk material handling and processing equipment.
