5 Major Pulp Testing Machines Every Paper Manufacturers Must Have

Pulp quality testing is one of the most important and critical aspects of paper making. Just like the foundation (or the raw materials) of every finished product determines its success, the quality of pulp determines the making of a quality paper in the paper manufacturing process. Each pulp quality evaluating instrument, be it a pulp centrifuge, vibration strainer, freeness tester, consistency tester, sheet former, or else, is designed to make the manufacturer’s task easy, effective, and successful. Here is the list of 5 major pulp testing machines that every manufacturer or pulp testing laboratory must have. 

5 Major Pulp Testing Machines Every Paper Manufacturers Must Have

1. Laboratory Pulper

The laboratory pulper is used to de-fiber the dry samples. It comprises a pulping container that has a rotor fitted at the bottom which works by a timing belt. The VFD controls the speed of the electric motor. In this pulping unit, the pulp is first torn and then water-soaked. It is then mixed to create a homogeneous suspension. 

2. Vibration Strainer (Johnson type)

The vibration strainer separates the sieves and fiber flocks from the pulp sample that is continuously fed into it. It is easy-to-use equipment, which is motor operated and comes with a slotted screen, water overflow and drain valves, and a control panel. 

3. Canadian Type Beating & Freeness Tester

The Canadian freeness tester is used to determine the freeness of the mechanical pulp, wood fiber, and also ground wood. As a result of the process, a Canadian freeness number is obtained, which tells about the drainage capacity of the pulps. This equipment is also a useful index of the amount of mechanical treatment given to the pulp.

4. Wet Web Strength Tester

This tester measures the initial wet strength and flexibility of the pulp. As a result of the testing process, a stress chart is obtained. On the basis of this chart, the running properties of the product in the machine and the effect of changes in pulp preparation are tested. The instrument is easy to use, comes with an LCD display, and has clamping jaws that together perform the test effectively.

5. Pulp Centrifuge

The pulp centrifuge machine is used to wash or de-water the pulp samples. It is a motorized unit that comprises a stainless steel container with timing belts and an S. S. perforated basket to perform the washing or dewatering process. The unit comes with various capacities and can be customized as per the user’s preferences.
