COMPLETE SPECIFICATION
Feeding or Charging Apparatus for Cement Kilns and Furnaces.
I, EDWARD CRAMER, of 6, Krupp-strasse, Berlin, in the German Empire,
Chemist, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
This invention relates to feeding or charging apparatus for cement kilns and
furnaces
Experience has shewn that the feeding or charging devices hitherto employed
in the cement industry do not enable the material packed into the said devices
to drop into the kilns in a similar position to that in which it lay in the feed devices
The object of my invention is to provide an anangement whereby the material
packed in the feed device drops in a similar position into the kiln to be fed. The
invention more particularly enables the material nearest to the periphery to come
to he against the periphery of the kiln without being disturbed or scattered
My improved feed device comprises a thin walled ing which is approximately
of the summe size as the interior of the kiln and a conical bottom which 18 formed
of separate narrow segments By ₁aising the apex of the cone the bottom can be
easily changed in such a manner that the material supported upon the extended
cone gradually slips down The space which is limited by the ing and the cone
18 designed to be filled with law cement stone and coke as is usual in the industries
If, now, the cone, which is similar to a fan and consists of segments, be raised by the
apex the mass lying nearest to the ring drops gradually down without causing
practically any movement in the layer The material which lies neater the centie
is, however, when the apex of the segmental cone is further raised, somewhat dis-
turbed, this 18, however, of no consequence as the outer dam upon which it mostly
drops lies igidly and undisturbed against the periphery of the kiln so that in the
feeding it comes first
The accompanying drawing illustrates apparatus constructed according to the
invention, Figure 1 being a vertical section and Figure 2 a sectional plan
thereof
The 1ing a is connected at its lower part by radial struts 6 with a vertical shaft d
and at the upper part to the inclined bars h The apex of the conical segments
or plates e are hinged to the ring which can be moved up and down upon the
shaft d For supporting the cone I provide the ring f which can be moved up and
down By raising the ring f the cone is widened For securely holding the parts
in position the ring is connected to the ring a by 1ods g.
The operation of the apparatus is as follows:
fan
e,
the
In order to form the bottom, the ring is pushed upwards to spread out the
when the ring has assumed its uppermost position which is the case when
the apparatus has been utilized for feeding and withdrawn from the kiln
ring with the extended cone e 18 then lowered until the said cone e comes to he
upon the ring c The cement material is then packed in The packed filling
apparatus 18 then introduced into the kiln and 18 emptied by means of a suitable
chain provided for this purpose The segments move without shaking until
сп

which the whole apparatus is withdrawn
L
This apparatus can be also provided with a device for packing the material
tightly at the periphery. This can be suitably effected by a ring which is
arranged inside the ring a and is operated by lovers which are pivoted to the rods hi
The compression 18 effected automatically as soon as the ring i, when the cone is
raised, presses upon the under side of the levers The opening or extension of
the fan like cone by the ring f can also be automatically effected.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The described means for feeding kilns or furnaces such means consisting of
a fan like cone adapted to be opened out and collapsed substantially as, and for
the purpose herein before described.
2. The feeding or charging apparatus for kilns or furnaces herein before described 1
and illustrated in the accompanying drawing
