We, CHARLES MOREL, of Domène in the Department of Isère, Builder, and
ADRIEN HEIMPEL, of Crest, Drome, Engineer, both in the Republic of France,
lo 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 has for its object a crushing mill for dry or wet materials such as
it is
cement, lime, plaster, alabaster, kaolin, quartz, phosphates and others;
especially suitable for crushing minerals.

following statement :-
This invention has for its object a crushing mill for dry or wet materials such as
cement, lime, plaster, alabaster, kaolin, quartz, phosphates and others; it is
especially suitable for crushing minerals.
The annexed drawing represents this mill.
In the drawing-

Figures 3, 4 and ɔ are detail views to a larger scale.
In these figures-
A is the frame. B the main shaft driving the whole machine. 6b are bearings
mounted on the frame. B' is a roller keyed on the shaft B. B' is the pulley
D is a cast iron ring in
driving the shaft. C is a roller mounted on the axis c.
which is a steel lining d serving as a track. E E' are balls placed on the track as
shown in Figure 1 and maintained in place by the adjustable partitions E. F is a
scraper to which the required inclination is given by means of the screw F working
the toothed sector F2 mounted on the scraper as shown in Figure 5. G is a
cylinder provided with a hopper G'. In this cylinder works the axis G' on which
is an Archimedian screw not shown in the drawing. 9 is a chain driving the
axis G. H is a cover. I an elevator. Ia toothed wheel. K a pit into which
water is run. L is the outlet orifice which may be regulated by means of a sluice
valve not shown.

The shaft B rotates at the rate of about 150 turns per minute.
it the motor roller B' which is provided with a steel tyre or hoop. The ring D
rests freely on this roller. This cast iron ring is formed of several pieces arranged
in any suitable manner. Inside it there is a recess or groove of suitable_shape
which receives the steel ring à forming a track. The weight of the ring D may
vary from 8 to 20 tons and more according to the materials to be crushed. The
roller B¹ in rotating drives the ring D which follows its direction of rotation. The
roller C serves as a guide to the ring and prevents it rocking. The materials to be
crushed are thrown into the hopper G and fall into the cylinder G and the
Archimedian screw which is in this cylinder distributes it regularly on to the

01

page_text: track d where it falls in front of the balls E E. These balls serve to lay
the material against the bottom of the track. They are maintained in place and
separated one from the other by means of the partitions E². The material passes
over the roller where it is crushed, then it meets the inclined scraper F which
throws it to the right and left of the ring D. Sieves may if it be thought
necessary be arranged on the inner side of the ring. These sieves are not shown
in the drawing. The scraper is provided with a regulating apparatus which allows
its distance from the track to be regulated. It is in fact advisable for it not to
touch the bottom of the track in order to leave a depth of material sufficient to
more easily cause adherence of the material which falls from the cylinder G.
If the apparatus be used for crushing wet materials such as minerals just, coming
from the mine or auriferous sand the separation of which has been carried out by
decantation the apparatus may be arranged in such a manner as to graduate the
fineness of the product.
The material to be crushed is thrown into the basin or pit K containing water.
This material is conveyed by the elevator I which throws it into the hopper G.
This elevator by reason of its special form shown in Figures 3 and 4 removes the
material and allows the water to escape.
The opening L is provided with a sluice valve which allows the height of the
level of the water in the basin to be regulated and consequently the fineness of
the material which flows from the orifice L. The scraper F causes the material to
fall into the basin K where it is again taken by the elevator.
It is useful in certain cases to place inside the ring a tube supplying the quantity
of water necessary for the carrying away and the crushing of the material. The
water necessary for the ejection by the opening L of the product when sufficiently
crushed is led into the decanting basin K in which the material is always in motion
on account of the elevator.
In certain cases the balls E E' could of course be replaced by suitably arranged
rollers.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :--
1. In a crushing mill the combination of a roller of suitable size and shape
rotating at a given speed and of a ring resting on the said roller, the weight of
this ring varying according to the material to be treated.
2. In a crushing mill consisting in a driven roller upon which rests a ring
rotated by the roller, the combination of a second roller serving to guide the ring
and prevent its rocking.
3. In a crushing mill the combination with the ring of one or several balls
arranged in the track of the ring to crush the material and lay it against
the track.
4. In a crushing mill the combination of an adjustable scraper of suitable shape
for disengaging the crushed matter and throwing it to the sides of the ring.
5. The combination with a crushing mill an elevator such as is shown in
Figures 2, 3 and 4 of the annexed drawing.
6. The mill for crushing dry or wet materials substantially as above described
and shown in the annexed drawing.
