A Hatschek machine for the production of fiber cement boards is provided, comprising at least three rotatable sieve cylinders suitable for rotating in a bath filled with cement fiber sludge, with liquid from the sludge flowing through the screen and leaving a thin layer of fiber cement on the screen, characterized in the presence of at least two baths, at least two …

Hatscheck process. The first method of fiber-cement manufacturing process was invented by Ludwig Hatschek in the 1890s. He combined slurry with cellulose, reinforcing fibers and Portland cement in water. This fed into a paper making machine in which a cylindrical sieve or sieves rotate through the slurry.

The Flow-on board machine is much simpler compared to a Hatschek machine and therefore easier to operate. The slurry flows directly onto the felt via a layer former (flow-on box). The flow-on box on the top of the felt forms a layer approximate 0.7 mm thick in the (adjustable) gap between the felt and the calibrating roll. Felt

The Hatscheck process of manufacturing fiber cement was an innovation made by the famous Austrian Ludwig Hatscheck in the early years of 1890. The process was a resultant of seven tedious years of cellulose experimentation of reinforcing the fibers using cement in water. The combination of cement, cellulose fibers and water (slurry) ended up in ...

itself including the delivery system for slurry to the Hatschek machine vats and delivery of flocculent to the system are also discussed and recommendations are made. The results disclosed here were obtained during the optimisation of the operation of a recently commissioned 4-vat Hatschek machine installed. Several flocculents were evaluated

A Hatschek process according to any one of the claims 1 to 9, wherein each of said monolayers is provided by accumulating fiber cement slurry on a rotating sieve drum and removing said accumulated fiber cement slurry from said rotating sieve drum as a monolayer, the width of said first type of monolayers in transverse direction being …

Hatschek machine Developed in the 1890s by Ludwig Hatschek, we still rely on this equipment today and follow many of the original principles. The sheets are formed by slurry that runs through a sieve, thus depositing a soft porous film of fibres – moved onto felt and subsequently passed onto a forming roller.

Pituitary gland, or pituitary for short, is characteristic of all vertebrates. As a "master gland" controlling a multitude of important functions in the body, its evolutionary origin has been an object of investigations of evolutionary biology for two centuries. Previous morphological, ultrastructural and immunohistochemical studies suggested the homology …

A Hatschek machine 100 for the manufacture of fibre cement sheets is shown in FIG. 1. The machine 100 comprises four rotatable sieve cylinders ( 101, 102, 103 and 104 ). Two pairs of sieve cylinders are rotatably mounted in one and the same bath 105, 106, respectively. Each bath has a separate feed line 107, 108, respectively, to supply fibre ...

Thereafter, the bucket feed 20, which is conventional in the use of a Hatschek machine, feeds the slurry from stock chest 19 to the cylinders 21 of the Hatschek machine through feed trough 22. As the slurry is fed through feed trough 22, tender or dilution water is fed into the slurry from water storage tank 23.

REINFORCED CEMENT SHEET PRODUCT CONTAINING NO ASBESTOS FOR FABRICATING ON HATSCHEK MACHINE ABSTRACT OF THE DISCLOSURE A fiber-cement product which is capable of being formed on a Hatschek machine consisting essentially of a Portland cement binder in the amount of between about 40% and 80% by …

formation on the Hatschek machine (Figure 3) by filtration of a dilute slurry of fibers and equidimensional sand and cement particles. This filtration process produces a film that is typically around 0.25 to 0.40 mm thick and each fiber cement sheet comprises a stack of these films. Thus, an 8 mm (5/16") thick sheet will consist of between 20 to

An important machine for product development and quality management is the Mini-Machine. The biggest advantage of this machine is that trial productions can be made without disturbing the running production. In addition, significantly smaller and therefore faster trial batches can be run on the Mini-Machine other than in regular production.
