.EWART CONVEYOR
y A GREAT SUCCESS

Eva Plantation Company has install.
ed the second Ewart removable inter.
mediate carrier and force feeder in it5
mill after q very thorough test last.
inP over a number Of months.
Bagasse eonveyors, or Intermediates
carriers, between mills. in cane sugar
factories, whether of steel sllt or belt
type, have many undesirable features.
Juice and fine bagassc pass through
the unavoidable openings. causing sour.
ing Of the juice, and require cleaning
continually. HI
Years ago scraper elevators were
commonly used to convey TIL agasse
from ono mill to the next. Thev were
, clearly, but formed rathc" an awkwar |
structure between the mills, as they
were not readily removable.
The EwaTt intermediate carrier is
IN Improvement on tn" formerly used
scraper conveyor and is de,iyned t.
embody the desirable fratu es aud
eliminate the undesirable ones.
BY taking out a few bolts and dis.
connecting the scTaper levers, the con.
veyor can be hoisted bodily out of the
way, thds giving free access to the
| mills and allowing the removal of the
lower rolls. The maccration water
strikes the bagasse from top and bot
! tom at the most favorable point where
the bagassc is in an expanded condi.
ton. .E.
No Splitting Between Mills
| The conveyor trough being wafer
tight prevents the spi!ling of the juice
and fine bagasse, thereby restricting
the losses caused bv the so ring of I re
Juice and eliminating the labor of
cleaning up. t..I
AS the tagasse leaves the forward
mill the angle iron flights, which move
at about the same speed as the surfaca
! of the discharge roll, engage the blan,
| ket, carrying 1T along through the
and feed rollers Of the next mill.
| No serious damage can he done Ia
the conveyOr by car links, pins, etc.
accidentally passing along with the
! bagasse.
The tail shaft, head shaft. driving
shaft, and likewise the flights auto
matieally adiust themselves to any
thickness of bagasse passing through
, the mill.
In the event Of the min not taking
the feed as rapidly as the bagasse 1.
moved along the trough, tins causing
it to pile up inhfront of the rolls, the
| head or driving end Of the feeder is
dramatically lifted by the bagasso
thus accumulated, swinging on the t i
shaft as pivot.
The whole design is inexpeuoivo a"f
substantial and is made up Of elements
that have proved successful in prac
tice. III
! Good Work At Eva
Francis NJ. Swanzy stated Yesterday
/ that the Ewart invention is doing re
markable work at Eva mill. InsteaC
of carrying the bagasse loose on to-
! of tho old style endless chain will
cross-slats, the blanket Is carried ~
ward by rakes. The bagasse is helC
| between the endless belt with PROJECT
ing rake teeth and a steel shute nuc
! is carried forward and forced into Ia,
next set of rolls
'"There is no spin from the side
OF the carrier and no waste or leak
age. ! saw bagasse blanket sixteer
in"hes thi"k forced straight into thu
rOlls,' Mr.. SWAMI said. "There hal
been no trouble whatever with this in
vention. 1t serves splendid rr-n~sN
"Water is sprayed onto the blanket
from above and below and on its jour
ney between the mills the bagasse alb
sorbs it all. Using the Ewart convey
or, Eva mill has averaged forty pei
cent maceratiOn.
:. c. j.. IIedemann, manager of tht
/ Honolulu Iron WORKS, stated vester
day that a good many Ewart convey
ors will be installed ON the plantation,
-aftcr the 1918 grinding season end 5
many orders having been placed BY
managers who have had the opportuni
| ty OF studying the work done. ~ O.
