PULP-DISTRIBUTING MACHINE.

Specification of Letters Patent.

Patented June 16, 1914.

Application led. April 5, 1913. Serial No. 759,201.`

To all whom t may concern Be it known that we, VYVYAN C. BENNETT and GREY DRUMMoND, both subjects of the King of Great Britain, residing at ElV Oro, Estado de Mexico, Republic of Mexico, have invented certain new and useful Improve-` ments in Pulp-Distributing Machines, of which the following is a specification.

This invention relates to improvements in machines for distributing o-re pulp to ore dressing machines, such, for instance, as tube mills. The improved machine is especially intended to supply a gang or series of ore dressing machines, and its object is to simultaneously deliver to any particular number of machines up to a certain point, streams of pulp of uniform character, consistency, and volume, and it is especially capable of eiecting equal, or substantially equal, divisions of the pulp for either all of the machines of the gang or series, or for a number of said machines less than the total number thereof in the gang or series. That is to say, assuming, for the sake of example, that there are siX ore dressing machines to which the pulp is to be distributed: the machine which forms the subject matter of the present invention is adapted to deliver uniform and equal streams of pulp to all of the six dressing` machines, or to any live, or four, or less number of such dressing machines.

It will, of course, be understood that the amount of pulp supplied by the feed launder or feed pipe is not affected by the number of dressing machines-to which the pulp is to be distributed, and consequently, that the streams of pulp passing to said dressing machines, while uniform in character and volume with one another, will be of greatervolume in the case of a smaller number of dressing machines to be supplied than they will in 4the case of a larger number of such machines.

The invention includes means for convenicntly and quickly effecting the interchangeable application of the machine to different particular numbers of dressing machines at different times.

The essential features ofthe invention are a collecting pan or equivalent provided with a certain number of compartments, a dividing pan or equivalent which receives the pulp from the collecting pan and in which the streams to supply the different dressing machines are formed, a distributing element which receives the pulp from the battery launder and by which the pulp is passed to1 the collecting pan, and a number of distributing spouts or connections leading from the several chambers of the collecting pan and mounted so as to be put into communi-- cation with any desired chamber of the distributing pan. Under ideal conditions, the number of chambers in the collecting pan is a multiple of the number of chambers in the dividing pan, and the discharge spouts or connections from the collecting pan are so arranged that equal numbers thereof communicate with the several chambers of the dividing pan, or with a selected number of the chambers of the dividing pan.

An embodiment of the invention is illustrated in the accompanying drawings, wherein:

Figure l is a vertical central sectional view of a machine in which the features of improvement are incorporated; Fig. 2 is a plan view thereof; Fig. 3 is a plan view of the dividing pan. This iigure shows diagrammatically and by dotted lines the relation of the discharge spouts from the collccting pan, and of the tubes which lead from the several chambers of the dividing pan to the ore dressing machines. Fig. 4l is a detail perspective view of the distributing element.

Similar characters of reference designate corresponding parts throughout the several views.

The working parts are supported by a frame work of any suitable construction, and consist essentially of the distributing` element l, the stationary collecting pan 2, the dividing pan 3, and the discharge spouts or connections 4t by which the pulp is transferred from the pan 2 to the pan 3.

In the embodiment shown, the element 1 is mounted for rotation and is in the form of asnail channel. The channel l is carried by a pendant shaft 5 which is revolved by the reaction of the pulp stream or by any suitable means and is arranged in relation to a feed launder or feed pipe 6 and to the chambers or compartments 7 of the pan 2. The launder 6 discharges the pulp in a zone concentric to the axis of rotation of the channel 1 and the pulp uniformly discharges from the open end of said channel into the successive compartments 7, consequent to the rotation of the channel relatively to said compartments. To facilitate the discharge of' pulp from the chambers or compartments 7, each compartment has an inclined bottom communicating at its lowest point with .a discharge duct 8, and the spouts 4, which are of somewhat ogee form, and terminate at points above the pan 3 are in communication with the several discharge ducts 8 and are connected to the base plate o f the pan 2, preferably through the agency of swivel joints 9.

The otlice of the chamber 3 is to divide the pulp into a number of streams of uniform consistency and volume, corresponding to the number of dressing machines to which the pulp is to be delivered. For this purpose, the chamber 3 is divided into a number of compartments l0, which are prefeih ably of annular form and are concentrically related, each compartment 10 preferably having a bottom lining made up of a mixture of concrete and sileX and faced with cement. Each compartment 10 is connected by a discharge pipe 11 to a particular dressing machine of the group to be supplied. The bottoms of the compartments l0 are inclined, and the tubes 11, of course, lead from the lowest point of said bottoms.

Tn the embodiment shown, the chamber 2 has twenty-eight compartments 7, and the chamber 3 has seven compartments l0. In such event, it will be understood that the maximum number of dressing machines constituting the group to be supplied will be seven. t is also assumed that all of the dressing machines are to be supplied with pulp, in which ease the spouts 4 are so arranged that four of them discharge into each compartment l0, (Fig. Tt will be obvious that the spouts 4 and the chamber 3 thus coact to produce seven streams of pulp of uniform character and volume which are passed by the several pipes l1 and the several dressing machines. if, for any reason, all of the dressing machines are not all to be used, but a number less than the total number are to be supplied, the spouts 4 are adjusted relatively to the compartments l() of the chamber 3 to effect a division of the aggregate mass of pulp into equal or substantially equal streams, corresponding` in number to the number of dressing machines to be supplied. In some cases it may not always be possible to have a theoretical equality of the streams, but in anv event, the streams will be substantially equal. To obtain an absolute equality of the streams under all conditions, the number of compare ments in the chamber 2 should be the least common multiple of all the numbers of compartments which can be selected froml the chamber 3. To illustrate: Assuming that there are four dressing machines and that the chamber 3 has but four compartments 10, the chamber 2 will have twelve compartments 7, since twelve is the least common multiple of the factors l, 2, 3, and 4. But when the number of dressing machines and the number of compartments in the chamber 3 is over 4, it is not feasible to have absolute equality of all the streams, because the member which is the least common multiple of the several factors which can be produced from the number of compartments in the chamber 3 will be such that a. corresponding number of compartments i in the chamber 2 would be impracti tal, because it would render the machine too cumbersome. Thus, if it be assumed that there are five compartments 10 in the chamber 3, the least common multiple of the

numbers

1, 2, 3, 4, and 5 is G0, but the use of (30 compartments 7, suitable for the purposes in view, would be impractical, for the reasons stated. As a matter of fact, it is impractical to have more than about thirty-tive compartments 7, and such a number of compartments 7 will be sutlicient to enable the production of substantially equal streams within the numerical limits of the average group or gang of dressing machines.

Under normal conditions, it is important that the supply of pulp to the machines should be uniform, and as fully explained above, the principal object of the invention is to secure this uniformity. lt may some times happen, however, that it is desirable to supply a greater or less amount of pulp to some one machine of the group than to the others. Thus, in the case of tube mill machines, it may happen, for one reason or another, that one machine is not working eiiiciently, for example, owing to its not having its requisite load of grinding pebbles. In such a case, it might be deemed advantageous to deliver a stream having less volume to this machine than the streams delivered to the other machines. This result is achieved by such an arrangement of the spouts or connections 4 as will malte the particular stream to be delivered to the machine not having its requisite load of grinding pebbles of less volume than the other streams, and to make these other streams uniform in volume with one another, or as nearly uniform as possible under the circumstances. Thus, in the case assumed b v the drawings, where seven machines are to be supplied, and under ideal conditions, each stream will be made up of the product delivered by four of the spouts 4; in the event that one of the dressing machines, for any reason, does not have the capacity for a stream corresponding to the product of four spouts 4, the channel 10 which supplies this particular dressing machine may, of course, receive the product of but three of the spouts 4, in which case the odd spout will be turned to communicate with some other channel, preferably the channel of the machine which, if there is any distinction in capacity, as to the remaining machines of the group, has the greatest capacity.

The improved machine is also useful in that one of the spouts 4 may without interference with the normal operation of the machine be turned to deliver a stream into the sample boxes, and in this way an accurate sample may be obtained. By noting thel time element in taking the sample, a close estimate of the quantity of the material flowing through the plant may be made.
