Application filed November 14:,1919. Serial N 0. 338,064.

To all w 710m it may concern:

Be it knownthat I, VVILBL'R H. Peon, a citizen of the United States, residing at the city of Los Angeles, county of Les 1 ngeles,

tate of California, have invented new and useful lm n'ovements in the Methods of and Machines for Centrifugal $eparation, of which the following is a specification.

Myi vention relates to a method and machine for separating by centrifugal action commingled material, the atoms of which are of different specific gravity and more particularly to separating valuable mineral or other matter from non-valuable matter and the object thereof primarily is to produce a. machine which will concentrate ore in which the operation is continuous.

In the drawings forming a part of this application I have illustrated my invention as applied to concentrating ores and will so describe it althou h the machine ma be used for other purposes.

Figure 1 a front elevation partly in vertical central section of my machine, Fig. 2 is a vertical section of a fragment of the rotor taken on a line through the discharge ports of the heavier matter on a plane at right angles to the sectioned matter of Fig. 1. Fig. 3 is a central section through a dis charge port of the lighter matter. Fig. at is a fragmentary detail of certain channels in the rotor.

Referring to the drawings is the frame.

pulp chamber 16 and water chamber 17.

Plate has an outwardly projecting flange 18 which is'located a short distance from the edge and extends to and contacts with the inner surface of the casing as best shown in 1 and At spaced distances apart this flange is cut for the reception of removaliile port plates 19 having ports 20. These plates can be replaced when worn and changed for others havinglarger or smaller ports therein as desired. Between the flange and casing and separating the ports from each other are spacer blocks 21 which leave small chambers 22 between their ends and the flange and casing. Vithin flange 18 and extending from plate 15 to the casing are channel blocks 23 which are spaced apart and form separating channels 23 From plates 19 channels 23 are formed in the blocks 23 which project inwardly with increasing width and terminate at outlet ports 2% provided in plate 15. It will be observed that there are as many of these channels and outlet ports as there are port plates. The number depends on the size and capacity of the machine. 011 the other side of plate 15 and extending to the casing is an annular water-channel block 25 in which are toriiied supply channels 26 which extend from theinner edge of the block and terminate at the edge thereof in ports 27 which open into chambers 22. Intermediate channels 26 are channels 28 which extend from ports 21 to the outer edge oi the block and let port plates 30. Plates 30 are removably secured in holes 32 in the rim of casing 11 so that they can be renewed when worn or replaced by plates having larger or smaller ports as desired. The rim of the casing has holes 33 therein for the reception of outlet port plates 34 having ports 35 therein. Plates 3% are removably secured so they can be replaced when worn or replaced by plates ha ving larger or smaller ports therein. For distinction ports 29 will be called light discharge ports and ports 35 will be called heavy discharge ports. On journal 14 is secured pulley 36 to which power is applied to drive the rotor. Extending through journal 14 is the water supply pipe 37 which furnishes water to chamber 17. This pipe has a regulating cock thereon and is connected to a suitable pressure supply of water not shown. Extending through journal 13 is the pulp supply pipe 38 through which pulp is supplied to chamber 16. Surrounding casing 11 is a receiving casing 39 which is divided into a heavy material receiving chamber 40 and a light material receiving chamber 11 by buffer ring 42 against the sides of which the material from the rotor is thrown. Pipes 43 and 44 carry the discharged material to appropriate places.

While I have described the use of water it is obvious that compressed air could be used in the place of water where a dry separation is desirable or when commingled li uids are to be separated.

.n the operation of my machine power is applied to turn the rotor the material to be o l o p register with discharge ports 29 in the out- Q revs-nee separated is fed into the center into a chamber. 16 from which extend channels of decreasing Width to the heavy discharge ports 20 and then said chambers increase in Width to the ports 24 through the partition. The heavier particles hug the outer Walls of =these channels, which walls are at about rightangles to the radius but may be at a different angle if desired. 1 have found that angle'produces good results in ore concertration. A the same time that the material to be separated is fed into the rotor, Water or compressed. air is fed into chamber 17 from which channels run to chambers :22 into which the heavier particles are dis charged; The fluid that enters chambers is under pressure and a portion passes inwardly through ports 20 and passes out through fthose portions of the channels marked 23', ports 24, channels 28 and ports 29; thereby aiding in carrying outthe lighter material. The other portions of the fluid that enter chambers 22 pass out through ports With the heavier materia From this description it will be seen that concern tration ofinaierial is continuous, and by of the ports and the pressure-of the fluid perfect separation is obtained. 7

Having described my invention, l. claim:

1. 'A separator comprising a casing adapted to revolve said casing having channels angularly disposed to a line passing through the center thereof and ports opening out of the ends of the channels said chahnels there being one port at the end of each channel, and one intermediate and forming a means to feed material to said chamber, and means to cause a fluid under pressure to pass through the intermediate ports and then to pass out of said end ports.

'2. A separator comprising a circular forming a central chamber adapted to be revolved channels in said casing angularly disposed tothe radius thereof leading out of said chain said channels having ports leading t-l' creirom, one at the end and one intermediate the ends; means to feed material to be separated into said chambcrgand central chamber; be separated into means to supply a fiuid under pressure to pass i1to the channels through the interme diate ports and on out of the end ports.

A separator ing having ports in the edges thereof and forming a central hamber, a partition plate having ports .lih rethrough separating said chamber into ,ai water chamber and a pulp chamber; said plate having on one side a flange reaching the casing, said flange being cut out at desired distance-s5 port plates having ports therein mounted in the cut away portions of said flange; channel blocks spaced apart to form channels of decreasing width from said chamber to said port plates, spacer blocks between said casing, flange and partition plate; an annular channel block on the other side or said partition plate said channel block having radial channels extending from the Water chamber and terminating at the pointsof separation of the spacer blocks, and other channels intermediatethe first ichannels extending from the ports in the partition plate to ports in the edge of the casing.

4:. A method for separating matter comprising; first causingstratification of the matter to be separated by centrifugal force, then discharging the heavier matter through ports, the lighter matter passing to other ports, and causing fluid pressure to.fioW through said ports'iagainst the outward flow of the heavier particles and then to flow out or the other ports with the lighter particles 5. A method of separating matter comprising: l, causing stratification in a channel by centrifugal force of the matter to be separated; 2, then discharging the heavier matter through port-s opening out of said channel intermediate its ends; 3, causing fluid pressure to flow through said ports against the outward flow of said heavier particles; 4, then causing said fluid and the lighter particles flow out through ports at the end of said channel.

In Witness that I claim the p foregoing I have hereunto subscribed my name.
