Pulverizing Super-phosphates and other Materials.
We HENRY DAVID SALOMONSON, Manufacturer, and JULIUS LAUBREIMER, Engineer,
both of Kralingsche Veer, near Rotterdam, Kingdom of Holland do hereby declare
the nature of this invention to be as follows:-
Heretofore the reduction of super-phosphates and other materials of a similar
nature has been effected by hand or by desintegrators or by spiked rollers which
revolve against each other. In both kinds of machine the efficiency is considerably
impaired when the supor-phosphate is not well dried and it moist a pulverization or
reduction is almost impossible. The chief fault with the desintegrators is that they
soon clog up, while machines with spiked rollers especially suffer from the defect
that the super-phosphate is pressed into cakes and the rollers thus run themselves
fast.
To avoid these defects we make machines with a quickly revolving spiked roller
of any suitable or ordinary form and combine therewith another roller or part roller
which is made to rock or revolve there and back on its axis and is furnished with spikes
which pass between the spikes on the revolving roller. This rocking roller or part
roller enables the reduction to be effected and serves also as a cleaning roller to the
other roller. Further in order to still more effectually prevent the adhesion of the
material we prefer to provide above the oscillating roller or part roller a series of
fixed spikes which are so arranged that the circumference of the oscillating roller
glides past their lower ends. The oscillating roller may be actuated by means of
lever and rod from an eccentric crank or cam and the stroke may be made
adjustable in any suitable manner to meet the requirements of different materials
or conditions of same. The speeds of the revolving spiked roller and the oscillating
spiked roller are by preference somewhat different so that the former in some instances
might make about 250 revolutions per minute and the latter about 150 there and back
movements per minute.

Pulverizing Super-phosphates and other Materials.
1, HENRY DAVID SALOMONSON, Manufacturer and JULIUS LAUBHEIMER, Engineer
both of Kralingsche Veer near Rotterdam Kingdom of Holland 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 :-
Heretofore the reduction of superphosphates and other materials of a similar
nature has been effected by hand or by desintegrators or by spiked rollers which
revolve against each other. In both kinds of machine the efficiency is considerably
impaired when the superphosphate is not well dried and if moist a pulverization or
reduction is almost impossible. The chief fault with the desintegrators is that they
soon clog up, while machines with spiked rollers especially suffer from the defect
that the super-phosphate is pressed into cakes and the rollers thus run themselves
fast.
To avoid these defects we make machines with a quickly revolving spiked roller of
any suitable or ordinary form and combine therewith another roller or part roller
which is made to rock or revolve there and back or backwards and forwards on its
axis and is furnished with spikes which pass between the spikes on the revolving
roller. This rocking roller or part roller enables the reduction to be effected and
serves also as a cleaning roller to the other roller. Further in order to still more
effectually prevent the adhesion of the material we prefer to provide above the
oscillating roller or part roller a series of fixed spikes which are so arranged that the
circumference of the oscillating roller glides past their lower ends. The oscillating
roller may be actuated by means of a lever and rod from an eccentric crank or cam
and the stroke may be made adjustable in any suitable manner to meet the require-
ments of different materials or conditions of same. The speeds of the revolving
spiked roller and the oscillating spiked roller are by preference somewhat different so
that the former in some instances might make about 250 revolutions per minute and the
latter about 150 movements backwards and forwards per minute.
Referring to the accompanying sheet of drawings Figure 1 shows one form of
machine constructed according to this invention in part sectional side elevation.
Figure 2 is a plan thereof and Figure 3 an end view.
The roller or part roller is provided with spikes and mounted opposite the roller a
which is also provided with spikes, the former being connected to the eccentric sheave e
mounted on the countershaft c¹ by the eccentric rod c² and lever d. As before stated
the part roller receives about 150 backward and forward motions per minute whilst
the roller & runs at about 250 revolutions a minute whereby the spikes take in between
the spikes on the part roller b.
The degree of the backward and forward motion of roller part 6 must be varied to
suit the character of the material.

page_text: This can easily be done, for instance by altering the position of the stud of the
eccentric rod in the slot of the lever d. The spikes e fixed above the roller part b
serves for the removal of any material which might stick, as the lower ends thereof
touch the circumference of the said roller part 6 during the backward and forward
motion thereof.
It is therefore quite impossible for the material to stick because of the backward and
forward motion of the roller b, the material is also easily reduced without becoming
smeary. The apparatus is actuated by means of the pulley / which is mounted on the
shaft of the spiked roller a. Motion is conveyed from the shaft of the roller a to the
shaft c by means of a pulley and a belt to the smaller pulley f mounted on said
shaft c' which latter also carries the eccentric c.
The machine may naturally also be used for reducing other adhesive materials
besides superploshates. Its efficiency is exceptionally great. This in the first place
must be ascribed to the circumstance that one of the rollers constantly keeps moving
backwards and forwards thereby effecting the loosening of material sticking thereto or
hindering the sticking fast of material and the clogging up of the rollers, whereas
heretofore both rollers revolved constantly in the same direction or directions.
The roller or roller part therefore fulfils a double purpose. On the one hand it
serves as a roller, rendering possible the reducing of the material and on the other
hand serving as the cleaning roller and thus preventing the running fast or sticking of
the roller a.
It is evident that the arrangement and mode of fixing the spikes in the rollers may
be varied without departing from the invention.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what.
claim is :-
:-
we
First A machine for reducing superphosphates and other material consisting of a
constantly revolving spiked roller (a) in combination with another roller or roller
part (6) moving backwards and forwards on its axis (¹) whereby the spikes of the
principal roller (a) take in between the spikes of the other roller substantially as
described and shown.
Second-The construction and arrangement of reducing and pulverizing machine
substantially as shown.
