Abstract

The invention relates to the storage and processing of bulk materials and can be used in mountainous deposits. The purpose of the invention is to increase the efficiency of storage by improving the quality of the particle size distribution of the material. In order to implement the method, first two forms are formed | a pile of bulk material on a flat storage surface, the lower version of which is mixed; it is on one side by the amount of stowage and safety berm. The stack is worked out by entering on the other side with a dragline-type excavator, the bulk material is transferred into a receiving bin 1, section 1, its device. After separation, the material remaining on the surface of the screening is placed in the lower Rus N1 tabel, and the material passing through the screening device 2 into the upper Rus, and the Jupe1 section, its device is set so that the laid split material innpnna is equal to the pzhrin of the run. Spob allows to significantly simplify the process of separating bulk material into fractions. 1 il. (ABOUT

The invention relates to the storage and processing of bulk material in a stack and can be used in construction, mining and other industries of the national economy.

The purpose of the invention is to increase the storage efficiency by improving the quality of the particle size distribution of the material.

The drawing shows a sequence diagram of the operations of drying, the elimination of the method and the structural elements of the device.

; The stack of bulk material of mixed fractions B is double-haired, lower rus: height h | It is mixed with respect to the upper Rus with a height ha on one side: by an amount equal to the width of the approach A and the I protection berm a. The next section | device C consists of a receiving bunker 1; sifting device 2, the length of which 1k is equal to the length of the surface: the slope 1o of the second russa stack and is set at an angle equal to the angle of the natural slope Bi of the bulk material iBToporo rusa; dump console 3, which is made with the possibility of changing the vertical angle of inclination a; supports, and the lower support of the device is located on the plate, the heel between the Rus, and; the top - on the upper platform of the top: his Rus stack.

: Example On a flat warehouse surface, they form a double-haired stack with: a plate between the Rus on one side. On the roof of the stack, a dragline-type excavator is installed and the stack is worked up with a width of A-steps, on the other hand, the entire height of the stack is Nsh. The spent bulk material of mixed: fractions is mixed, ayut into the receiving bin of separating device C. After separating the bulk material with a separating device, the material remaining on the screening surface forms stream I and through the waste console it is placed into the lower Russian stack under angle test

va va va. Bulk material that has passed through the screening device forms a flow P, which forms the second Russian stack. The adjustment of the speed of movement of the bulk material along the screening device is carried out by changing the angle of inclination of the moldboard in a vertical plane. The separating device is installed so that the width of the divided and stacked bulk material into the stack of the stack in the section is equal to the width of the penetration through the stack. As the stack progresses, the separating device is moved along the stack.

The proposed method allows storing bulk material of a different fraction in a single stack, which can significantly reduce storage areas and simplifies the process of dividing bulk material into fractions.

Invention Formula A method of storing bulk material, including forming a shtabel, dividing it from one side into two Russ to form pads, working off the stack from the other, opposite to the first, its side to full height, moving the material to a separation device and sorting it into fractions, that, in order to increase the efficiency of storage by improving the quality of the grain-size composition of the material, when dividing the shtabel, the upper platform of the lower rus is formed by a width equal to the total width of the When the material is sorted, the coarse fraction is placed at the foot of the first side of the stack, and the shallow berm is placed on the upper platform of the lower rus, and as a step of sorted material is formed, the separating device is moved along the stack.
