Abstract
A hose (200) is described, the hose comprising a first section (210) comprising a cross sectional area Aχ and a second section (220) comprising a cross section area kj. The first section is in fluid communication with the second section and, in use, the first section is located upstream of the second section. Additionally, Axis at least twice the size of A2. Use of the hose and a method of dispensing slurry are also described.
Claims13
A hose for use in the production of a building product from a gypsum slurry, the hose comprising:
- a first section comprising a cross sectional area A1,
- and a second section comprising a cross section area A2,
- said first section in fluid communication with said second section, wherein, in use, said first section is located upstream of said second section,
- wherein A1 is at least twice the size of A2,
- wherein said hose comprises a third section comprising a cross sectional area A3 located intermediate said first section and said second section,
- wherein said first section is connected to said third section by an elbow,
- wherein said first section comprises a longest dimension d1 in a plane perpendicular to its longitudinal axis, and wherein said elbow comprises an external radius of curvature at least half d1.
A method of dispensing a gypsum slurry including providing a hose with a plurality of distribution portions, where the hose comprises at least two sections with respective cross sectional areas A1 and A2, wherein the ratio of A1 to A2 is such that flow asymmetry in said distribution portions is below 1%.
