A spray drying chamber with a head section and a heat-resistant porous membrane, the porous membrane being detachable and the head section being displaceable vertically, whereby microdrops are sprayed into a spray drying chamber together with hot air, and whereby the microdrops are dried momentarily and a fine powder is produced.

A valve arrangement for distributing or spreading a two-component binder system, comprising a distribution pipe (1) which is intended to be carried by a vehicle and which extends transversely to the movement direction of said vehicle, wherein a first binder component is intended to be conducted through a first conduit or line (101) which includes the pipe (1), wherein a plurality of first valves (60) are connected to the pipe (1) at mutually spaced positions along the length of said pipe and fun...

This spray boom is provided with nozzles delivering spray under a shield that confines the spray to a downward-rearward direction. The boom is mounted on a conventional tractor with a freedom to swing upward and to the rear on accidental contact with an obstruction. The boom can also be elevated for transport. The outer section of the boom is yieldable and can swing back separately on contact with a tree trunk, and this outer section is also provided with a resilient whip extension to lay down g...

A spray nozzle for dry shotcreting is disclosed. The spray nozzle has a first member through which dry concrete mix is passed, a second member attached to the first member through which water is passed, and a spray nozzle head. The spray nozzle head has a plurality of openings for water inlet from the second member into the dry concrete mix which passes into the spray nozzle head from the first member. The openings are arranged either circularly or helically about the circumference of the spray ...
