The Continuous Screen Grader offers a relatively inexpensive machine, alternative to the Lift Roller Grader. This system uses a traveling mesh screen to separate produce into different sizes. If the produce is small enough, it will pass through the screen. Larger produce will progress to the end of the machine. Oversize produce is fed to screen grader for next grading.

The process can be repeated, and multiple sizing achieved, simply by adding additional Screen grader modules. Sizing efficiency is further aided by mechanical shakers that gently vibrate the produce on the screen.

Each grader module is provided with cross belt conveyors to carry sized produce away for further processing.

Salient features:

* Modules can cater for up to 20 tones per hour, depending on the produce variety
* Main frame constructed from mild steel, galvanized or painted or stainless steel
* G.I. Wire mesh or S.S. wire mesh of required size opening is supplied.
* Screen hole size can be matched to your sizing requirements
* Anti-cut rollers run underneath the screen to ensure produce does not become trapped in the mesh.
* Cross belt conveyors supplied.

Most modern papermaking machines are based on the principles of the Fourdrinier Machine. It has been used in some variation since its inception. The Fourdrinier uses a specially woven plastic fabric mesh conveyor belt, known as a wire as it was once woven from bronze, in the wet end to create a continuous paper web transforming a source of wood pulp into a final paper product. The original fourdrinier forming section used a horizontal drainage area, referred to as the drainage table.

Paper machines have four distinct operational sections:

The forming section, commonly called the wet end, is where the slurry of fibers is filtered out on a continuous fabric loop to form a wet web of fiber.

The press section where the wet fiber web passes between large rolls loaded under high pressure to squeeze out as much water as possible.

The drying section, where the pressed sheet passes partly around, in a serpentine manner, a series of steam heated drying cylinders. Drying removes the water content down to a level of about 6%, where it will remain at typical indoor atmospheric conditions.

The calender section where heavy steel rolls smooth the dried paper. Only one nip is necessary in order to hold the sheet, which shrinks through the drying section and is held in tension between the press section (or breaker stack if used) and the calender. Extra nips give more smoothing but at some expense to paper strength.
