i Y The present invention relates toimprove ments in drying apparatus.
' For drying lnoustrallyfona large scale substances. in the form of a paste,'1t"1s ad vantageous to use' the socalledll-luil lard-p apparatus.
Such'an apparatus comprises a brick heat-M ing-chamber through which hot air is blown by means of a fan. In this chamber aband 10 of wire netting ofconsiderable length travels over rollers Thewire net is similar to fencing nets, except that its meshes'havena width of about 10 mm. WVhen such anar row-meshed net is, drawn through the paste,-
1 the meshes become I filled with the paste which can then be driedinthis state by the current othot air. All thathasfthento be done to removetheldriedpaste'i'sftojbend the net more or lessl sharpjly over rollers of small diameter so that'tlie dried'material drops in pieces from the net; The appara- KtLtS glYQS' verysatisfactoryfresults; its efli- 1 clency 1s hlgh, and the sconsumption oiheat- V is favourable becausethe air; currentpasses 5 through the apparatus in a long path on tlie counter-current principlef The only drawback to the apparatus inquestion is thi /BX cessive wear and tear of the expensive netting, However carefully the rollers are mounted and notwithstanding the use of var ous auxlliary devices, such as guard rails, grooves on,
the rollers or pressure-rollers, for the purpose of keeping the band in constantposition,dis placement of the band laterally is bound to 1 occur and if this happens suddenly the net, is exposed to great tension'and stretched so 7 that it isstill further displaced laterally,'until itbecomes bent at the edge and therefore useless.
By our present invention in drying apparatus of this kind the rollers carrying the band of wire netting or other material are i mounted insu'ch a manner that they are kept in balanceby a system of springs operating ,actionofthe springs'in planes at right angles to each other. Normall'y,the roller loaded in the direction of the traction of the band: 7
and inaxialdire'ction of the roller. Thus the bearings may be mounted to slide, under I .A Huillard panyingsdr'awings, Figrl being a diagram- 1 matic vertical sect-ion and Fig a sectional, view along'line 21-2.
