Hydraulic Jet Headbox

The hydraulic dilution profile headbox of Scan Machineries combines the highest paper quality with low energy costs. Paper quality is improved and at the same time allows substantial savings in energy costs for our customers. Precise cross profiles of grammage (CD profile) are maintained and fiber orientation is ensured. All internal surfaces in contact with the stock flow are finely polished. Turbulence generators are combined with tube banks and nozzles for efficient operation and excellent runnability. Finest manufacturing precision and unique macro adjustment along with our high precision dilution profile injectors provides the highest paper quality and properties.

The slice lips are motorized to adjust the slice gap between the lips and for controlling the output of stock flow. All internal surfaces in contact with the stock flow are finely polished. Excellent stock dispersion from the headbox ensures the best sheet formation.

Function of paper machine headbox

The Headbox is designed to distribute a continuous flow of wet stock across the width of the machine and lengthwise as stock is deposited on the screen at constant velocities. Stock should be properly dispersed over all areas of the sheet-forming surface in equal quantities. The early headbox, more commonly called a flow-box or breast-box, consisted of a rectangular wooden vat that extended across the full width of the machine behind the fourdrinier breast roll.

Scan Machineries Paper Machine Headbox line can meet all customer needs in terms of production, quality, and application. We design and manufacture Hydraulic Jet Headbox, Air Pressurized Jet Headbox, and Open Type Headbox.

Benefits of Headbox

A well-constructed headbox will provide many benefits:

It can improve formation and paper quality, reduce number of breaks and downtime, fewer pinholes, dirt spots, improve runnability, increase machine speed. stabilized paper caliper, improve water removal, and reduce chemical cost.

All these properties are achievable, if the CD basis weight profile, main fiber direction, uniform formation, flatness, etc. are perfect.
