Hydraulic Presses Used in the Mining Industry

Hydraulic presses are indispensable tools in many industries, from fabrication and assembly to maintenance and repair. Not only do they help operators fit and bend sheet metal parts, bearings and equipment together, but they're also invaluable when performing maintenance on existing equipment.

Hydraulic presses employ hydraulic pumps to apply a constant force on steel cylinders, forcing them to extend and press material at an established rate. This can be done manually, pneumatically, or electrically depending on the application and press size.

Laboratory presses

Laboratory presses are devices that utilize pressure to condense and shape different materials. They're commonly found in laboratories, where their capabilities can be invaluable for scientific testing.

For instance, they're employed to press KBr pellets for FTIR (Fourier transform infrared spectroscopy) analysis or general sample pellets for XRF (X-ray fluorescence) tests. Furthermore, these tools have found widespread application within the mining industry for sizing aggregates and minerals.

In some cases, dewaterers and separators can also be utilized to separate different minerals. This is especially helpful in mines when removing metals from ore, separating them from other by-products, or cleaning the water used during production.

These presses come in a range of sizes and configurations, as well as being manually or electronically powered. Selecting the right one for your application is essential to getting optimal results.

Production presses

Production presses are commonly employed in the mining industry to dewater slurry, recover process water and safely discharge tailings. Chemical process applications also frequently employ production presses for purifying chemicals, recovering active ingredients from spent solutions and dissolving emulsions into their component parts.

Dewatering slurry requires high pressure to break up solid particles and remove any suspended matter from the water. After filling into chambers created by filter plates on a press frame, these solid cakes are then filtered through manifolds or spigots on each plate before being left behind.

After filtering, solids are discharged onto a conveyor or directly into the ground and another cycle begins. In many mining operations, leftover slurry from filtering can be reused in other processes to save plant managers money and create efficient operations.

A high-quality filter press can be an integral part of a dewatering process, particularly when it comes to disposing of tailings. Filter presses have applications in gold extraction processes, coal washing plants and iron ore beneficiation plants among others.

Hydraulic presses for sample preparation

Hydraulic presses are widely used in mining operations, as they offer a powerful way to exert immense pressure without needing heavy equipment or electricity. Furthermore, hydraulic presses don't need an initial start-up motor and can be operated manually.

Hydraulic presses work by elevating a piston that holds air or liquid pressure, enabling precise application of force. They may be manually operated or automated and equipped with various devices.

Laboratory hydraulic presses are commonly employed for pressing KBr pellets for FTIR (Fourier transform infrared spectroscopy) or general sample pellets for XRF (X-ray fluorescence). These presses are usually manual, using a lead screw and top anvil pressing face mechanism to hold the sample before compression.

Hydraulic presses for scrap baling

Hydraulic presses are widely used in the mining industry to perform various tasks. They are capable of straightening shafts or sheets as well as compressing powdered materials into various shapes and sizes.

Hydraulic presses come in horizontal and vertical varieties, used to mount or unmount wheels, bearings, gears, sheaves onto shafts, axles, rolls or armatures.

Additionally, hydraulic press machines apply pressure to metal in order to bend or form it into a desired shape - this process is known as stretch forming.

Vertical and horizontal presses can also be employed in the bending process. These machines feature a large table where pressure can be applied to workpiece in order to shape it into desired shapes.
