A WIRE RANGE OF PARTS FOR YOUR SCREEN BOX Vibrating screens need to vibrate in a linear motion, the screens need to be correctly tensioned and washing requires proper nozzles. We offer a wide range of accessories for vibrating screens to ensure proper and safe operation.

Screen panels require proper tension and bedding to perform at their best with minimum breakdowns. Cappings act as a bumper between the deck and screen mesh. It is very important to fix the screen mesh tight to the deck as a lose connection will destroy the screen in a short period of time.

Rubber buffers are an important part of a vibrating screen. Screen operation should be strictly linear in line with the material flow and side movements should be minimised. Especially during start/stop operations, side movements increase as the screen passes through amplitudes close to its natural frequency and it resonates. Side rubber buffers prevent the screen from moving sideways.

While a large number of engineers try to minimise the vibrations in different applications, vibrating screen manufacturers try to make the best of it. Proper vibrating patterns are not possible without flexible mounts. Springs are the most common type of vibrating screen suspension. They are durable and easy to install and service.

Washing is one of the most important stages in aggregate and mineral processing applications. Generally, washing is performed by spraying water under pressure on the top of the material flow. Washing nozzles are special attachments to the pipes that spread the water over a wide coverage area. This water washes off the clay and dirt.

Declogging rods have been developed to further improve the self-cleaning properties of anti-clogging screens. Declogging rods bounce on the PU strips and create additional shock that helps to shake off stubborn sticky material from the panels. Declogging rods can be connected in multiple parts to completely cover the screen area.

Vibratory screening equipment is used to screen or classify wet or dry materials, like wet ash or dry frac sand, into multiple grades by particle size. They are also used to dewater or dry waste material before disposal. This type of high frequency vibrating equipment only drives the rectangular polyurethane screen panel, while the frame remains fixed. High capacity screening equipment can screen or classify material ranging in sizes from 1/8 inch (3mm) down to 325 mesh.

The Derrick Stack Sizer is a high capacity, multiple deck, wet screening machine capable of high capacity wet screening in a small footprint. A single slurry input is equally divided in a Derrick flow divider prior to the Stack Sizer. Each screening deck then makes a particle size separation on the Derrick Polyweb Urethane screen surfaces. The undersized fraction is collected from all decks in a common manifold to a single discharge. The oversize fraction is collected in the large hopper and discharged to a common point.

Dewater and recover fines from aggregate and sand processing wastewater WITHOUT the use of expensive polymers or chemicals. With many installations throughout North America, the Derrick Fines Recovery System is proven successful in the field and continues to lead the way for the aggregate industry.

Derrick MP screen panels are constructed from a special high temperature polyurethane material. They are a direct replacement for the traditional wire mesh panels currently used in the Rotex MegaTex screeners. These panels have a tapered opening to greatly reduce blinding issues commonly experienced with wire mesh panels. Because of the reduced blinding, the screen production rate can be increased over wire mesh panels. Typical life span is greater than 6 months. Urethane screen panel sizes are available for typical frac sand production.

High capacity wet screening and dewatering equipment provides a wide range of sizing and classification tasks. Wet screening equipment efficiently screens out fines and classifies oversize particles. Dewatering units have proven throughput of up to 300 TPH (tons per hour) and are designed to maximize solids recovery and minimize wastewater.

The Derrick Stack Sizer is a high capacity, multiple deck, wet screening machine capable of high capacity wet screening in a small footprint. A single slurry input is equally divided in a Derrick flow divider prior to the Stack Sizer. Each screening deck then makes a particle size separation on the Derrick Poly Web Urethane screen surfaces. The undersized fraction is collected from all decks in a common manifold to a single discharge. The oversize fraction is collected in the large hopper and discharged to a common point.

The Derrick SuperStack provides high capacity, high efficiency separation of fine wet particles. The eight screening decks operate in parallel and include a front-to-back tensioning system that increase the screening capacity up to 3 times that of the best fine screens currently available.

The Derrick HI-G Dewatering Machine is designed to maximize fines separation and recovery and provide drying capabilities to a wet screening and dewatering system. Powered by twin electromechanical 2.5 horsepower Super G vibratory motors, this units rotary speed (1750 RPM) and stroke length (019 in.) combine to create 7.3 Gs of screen surface acceleration. Water and fine solid separation are conducted efficiently, with component parts designed for maintenance-free operation.

This high-capacity wet screening and dewatering equipment is designed to dewater up to 300 TPH (Tons Per Hour) of primary sand products, delivering high-quality production sands (asphalt, concrete, mason, and others). Each unit houses over 62 square feet of screen surface area, of which nearly half is open area, resulting in an efficient and high-volume dewatering capacity.

Linear motion screens are designed for solids recovery, dewatering, and dilute slurries with low quantities of oversize. These screens are a versatile addition to a variety of wet screening and dewatering processes and are ideal for compact working spaces, with its low headroom requirements and high screening capacity. They efficiently purify viscous slurries, removing grit and other small-particle contaminants.

The screen frame can be angled from +10 to -15, with highest fluid capacity when locked into an uphill position. The equipment's linear motion conveys oversize materials out of the pool efficiently, discharging them into a dewatering process area.

The Repulp Screen efficiently screens out fines and undersize particles, resulting in clean and consistent oversize material. Spray nozzles are focused upon rubber-lined wash troughs (instead of being focused directly on screen surface), reducing wear and providing evenly distributed fluidization. Vibrating motors feature sealed bearings that are permanently lubricated and require minimal maintenance.

These machines feature multiple stages of screening and repulping, resulting in the highest rate of undersize particle removal possible. Repulp screens can be equipped with a split undersize hopper, allowing for a variety of separation sizes, and cut points.

The High Shear Screen effectively processes clay slurries. While traditional wet screening and dewatering machines feature a low plane of incline (resulting in bridging and blockage issues with platy minerals found in clay), High Shear Screens are set to a 45 degree panel angle. The result is a screening solution that can handle difficult slurries and platy minerals.

The Multifeed wet sizing screen is made up of three independent screening machines that provide three times the effective width of a conventional screen, mounted in a single frame and driven by one vibrating motor. The three separate feed streams are divided equally through a flow divider system located on the machine.

The dry screening equipment featured below use high speed, low amplitude, and vertical elliptical motion to screen dry materials such as sand, iron powder, nickel powder, polyethylene pellets, coal, glass, and many other materials. These machines produce low amounts of sound and are fully enclosed for dust suppression. Light-weight screen panels and hinged and clamped covers provide easy screen inspection, removal, and installation.

The Front-to-Back (FTB) dry screening machine provides increased screening capacity, improved efficiency, and extremely fast screen panel changes. Customers using the FTB machine report screening capacity increases up to 50% with improved efficiencies in products ranging in size from 0.25 inch (6.35mm) down to 400 mesh (38 m).

These dry screening machines have been in use for over 60 years in the industrial minerals industry. They utilize a true linear motion to achieve higher screening capacities with smaller floor footprints. Screen pellets, powders, sand, crushed glass, coal, and many other types of materials that require fine screening.
