With more than 40 years manufacture experience, Fote Machinery has been a reliable solution for quarrying, building, road infrastructure and recycling projects around the world.
Some active pharmaceutical ingredients possess poor mechanical properties and are not suitable for tableting. Using fine sand silicon dioxide, we show that a coreshell structure, where a core particle sand is coated with a thin layer of polyvinylpyrrolidone PVP, can profoundly improve powder compaction properties.

The wear of metallic components used in gas and steam turbines due to erosive sand particles leads to a tremendous decrease in their lifetime. This wear can be reduced by the use of suitable erosion resistant coatings resulting in lower maintenance costs. In this context, multilayer CrCrN PVD coatings using an industrial coater were designed and applied on Inconel 718, a material which finds ...

Voids can form behind the pipe, causing formation subsi-dence and casing collapse. The well may also fill with sand and cease flowing. Or the surface equipment may be catastroph-ically damaged by erosion or plugging.

The bond behaviour of novel, sand-coated ultra-high modulus UHM carbon fibre reinforced polymers CFRP tendons to high performance concrete HPC was studied by a combined numerical and experimental approach. A series of pull-out tests revealed that the failure type can vary between sudden and continuous pull-out depending on the chosen sand coating grain size.
