Sheet Former »KCL« semi-automatic

Manufacturer: PTE-Pulp Test Equipment GmbH
(formerly manufactured and sold by Xell GmbH)

For automatic preparation of laboratory hand sheets with 250 x 250 mm square

Device Description

The Sheet Former is built upon a warp resistant stainless steel frame. This robust base holds the sheet forming column and the pneumatic couching device, both located on the left hand side of the waterproof work table. The control panel, including a touch screen display, start and stop button and other important controls, is located on the right hand side. Multiple gauges enable the operator to supervise the pneumatic couching process. The sheet forming process can be performed manually or automatically. Therefore, you can find a manual operation switch next to the touch screen display that allows you to control the individual steps of the sheet forming process by hand. Additional there is built into the table a vacuum pump, which allows to suck water through the formed sheet, id the dewatering by gravitation is not good enough (for very fine grinded pulp). A water recirculation system collects the water from the former and can be used for forming another sheets. At the end of the process (maybe 10 sheets are formed) the water can be analyzed to determine, how much chemicals are bound in the sheet and how much chemicals are in the water.

Test Description

After initiating the process by pressing the start button, the water column is being filled with water automatically. Now the suspension needs to be added. The filling process will stop as soon as the water has reached the set limit. Agitation will start according to the preset values prior to the calming process. The subsequent gravitational dewatering process will finally form the sheet upon the screen plate. If the dewatering process is not good enough, then by pressing a button, the built in vacuum pump starts and helps to dewater the formed sheet (this is in accordance with ISO 5269/2 and DIN 54358. Each step of sheet forming related to the former column can be executed manually via the manual operation switch. The former column can now be opened and the couching process needs to be performed. Therefore, two blotters need to be laid onto the wet sheet before lowering the couching device. After locking the couching unit the membrane is being pressurized and will perform the couching process pneumatically. When the set couching time has elapsed, the sheet is ready for pressing and drying. The drainage water is collected in a vessel and will be used for another sheet forming. There is a switch, where it can be switched between fresh water and white water recirculation.
