Frac Sand Screening Machine
A sand producer was looking to increase production rates at an existing plant by adding new frac sand screening equipment. Their goal was to produce a consistent 40 x 70 API standard product. The feed to the vibratory screening machines would be from a processed material stream that discharges from a hydrocyclone at a solid feed rate of 150 STPH.

A mineral sands producer used new vibratory screening machines (or repulping equipment) to recover garnet at over 90% efficiency. The older, conventional vibrating screens were only able to recover material at about 44% efficiency.

A silica sand wash plant required (4) dual motor vibratory screening machines. These linear-motion screens included high open area 25 mesh urethane screen panels. Spray nozzles were also incorporated into the design for increased fines removal.

These dry urethane screen panels were used on 16 vibratory screens to classify dry frac sand. The highly abrasive 20 to 120 mesh frac sand was causing rapid wear of the existing wire mesh screens. Average failure of the wire mesh screens was occurring in 3 to 5 weeks at a flow rate of 20 tph.

Derrick Stack Sizers 5 deck for fine screening and dewatering mineral processing
The Derrick Stack Sizer is a high-frequency, multi-deck screening machine used for fine screening and dewatering in mineral processing applications.
It is designed to achieve high screening efficiency, high capacity throughput, and a significantly smaller footprint compared to conventional screening equipment.
Stack Sizers are commonly used for separations down to 38 microns and are widely applied in mineral sands, iron ore, silica sand, and other high-tonnage processing operations.
It is a much better alternative to hydrocylcone separators, hydraulic classifiers, and less efficient low volume screening systems.

Bulk Bag Filler for Petroleum Coke Located Under Surge Hopper
A heavy-duty bulk bag filler was used to fill bulk bags with petroleum coke, or “pet” coke. The material is fed into a surge hopper, through the inflatable bag head, and then into the bag. A pneumatic slide gate is used to start and stop the flow of material. The bulk bag filler did not include a scale because weight accuracy was not a project requirement. Once the bag has been filled, it is removed from the loader using a fork lift and placed into shipping containers for export overseas.

Bulk Bag Unloader with Incline Conveyor for Crumb Rubber
This bulk bag unloader meters and unloads crumb rubber from 2,000 pound bulk bags with a maximum height of 72 inches.
Category | Magnetic Separation | Recycling Systems |
Waste wire is brought into a recycling plant as baled or loose wire.
The wire is placed on a conveyor and travels to a shredder, where it is ground up and shredded into small pieces. This separates the insulation from the wire.
The shredded pieces are conveyed under and inline self-cleaning overhead magnet. The magnet removes metallic shredded wire pieces from the conveyor and drops them into a container below.
