Wet Drum Magnetic Separator

タイトルまたは説明

Wet Drum Magnetic Separators :
STL is one of the leading manufacturers of ore dressing equipment. The present range of STL process equipment enables us to provide complete packages. Magnetic wet separators constitute an important part of the product range and are known for advanced engineering design and excellent performance.
As a result of continuous development in separator technology STL can offer a complete line of magnetic wet separators to the mining and mineral industries.

Product Models and Sizes the STL Magnetic Set Separator DIA. ***0MM
STL's wet permanent magnetic separators are offered in sizes of dia.***0 mm and **6mm in Lengths of up to ***0mm. Three basic separator designs are available for cobbing, roughing and finishing/cleaning applications. Each type can be supplied in single drum or multiple drum stages of taco nite or magnetite and also for recovery for magnetic medium in dense media plants. The stationary magnet yoke is an assembly of strontium-ferrite permanent ceramic magnets. The rotating drum is available with optional rubber or stainless steel covers. The magnetic flux pattern will match the tank configuration for optimum performance.
STL's magnetic wet separator dia **6 x **0 mm is the smallest full scale separator in the **6 series and is primarily used for pilot plant tests. The separator can be delivered in concurrent, counter current and counter rotation versions.
STL's magnetic wet separator for laboratory use have drum dimensions dia. **0 x **5 mm and dia. **0 x **0 mm and are suitable for batch or continuous testing. The test results from the STL laboratory separators correspond closely to those obtained in full scale operation.
STL's magnetic wet separators have been developed in close cooperation with the Swedish mining industry for treatment of magnetite. A prime consideration in its advanced engineering design has been high capacity, improved metallurgical performance and highest availability. The separator is constructed as a separate unit consisting of drum with magnet yoke, tank and drive package, all mounted on a heavy-duty frame. The design of the frame allows any number of units to be connected in series as multi-stage installation. This design offers a flexible flow sheet layout.

Adjustment of Magnet Yoke and Drum :
The magnet yoke is mounted on the stationary drum shaft and its position can be adjusted (+/**5 °) by a lever at the end of the drum shaft to optimize running conditions in accordance with tank design and type of ore. The gap between tank and drum, which determines the pulp flow speed, can be adjusted vertically by shims inserted under the bearing housing and shaft support. Horizontal adjustment is by slotted holes.
Drive Unit :
The standard drive train consists of a shaft end mounted torque arm speed reducer outside the tank with V-belt pulley driven from a standard electric motor. This arrangement provides a smooth protected transmission and has several advantages compared to chain drives. Also other drive arrangements can be supplied.
The V-belt drive is protected by a steel guard. As an alternative the separator drive unit can be supplied with an easily removable fiberglass cover. These covers protect the entire drive unit and motor, with opening for lubrication maintenance and inspections.
The Steel V-belt guard is preferred for users in extreme climatic conditions, e.g. tropical and subtropical.
Feed and Discharge Box :
The feed box is designed for high capacities with a uniform distribution of pulp over the full length of the drum. Removable tramp screens can be provided as an option.
The discharge box is bolted to the heavy-duty frame and designed to give a smooth and easy discharge of the concentrate. Wear surfaces are typically rubber-lined.

Wet Drum Magnetic Separators Appications :
The capacity varies considerably depending on metallurgical criteria. Most important variables are magnetic susceptibility characteristics of the magnetic particles, degree of liberation and size of the feed.
Mechanical features of the separator as tank design, magnet system and drum diameter do of course also effect the capacity. The following capacity figures can be used as guide-lines for STL magnetic wet separators in iron ore processing.

• Above Figures applicable for iron ore processing.
• As summary of the field experience and confirmed by test runs, following advantages can be emphasized when using the dia. ***0Mm separators specially for new projects:
• Reducing the total number of separators required.
• Lower operation and maintenance costs.
• Less number of pumps, pulp distributors, etc
• Less occupied floor space.
• Lower building cost.
