Abstract

The utility model belongs to a roller-disc type crusher used for crushing hard ore rocks for a metallurgy department, a mine department and other departments, and is composed of a crushing disk horizontally installed, a plurality of crushing roller wheels arranged along the radical direction of the crushing disk, etc. The crushing roller wheels rotate in opposite directions under the action of a drive device. Each part has sufficient strength, and can be effectively wedged into hard ore rocks and crushes the ore rocks. When the breaking disk rotates back, a plurality of crushing roller wheels work at the same time, so production efficiency is higher. The interstice of an exhausting end can be adjusted as required to ensure product granularity to be thin and uniform. The granularity can be smaller than 10 mm. The utility model is a more ideal crushing equipment.

Description

Roller-disc disintegrator

The utility model belongs to the breaking machine with roller and disk that is specially adapted to the tough and tensile ore deposit of fine crushing rock that departments such as metallurgy, mine use.

At present, broken main all kinds of jaw crushers, gyratory crusher, the gyratory crusher etc. used of tough and tensile ore deposit rock.The groundwork principle of above disintegrating machine all is to utilize the relative opening and closing campaign of two workpieces and finish ore deposit rock fragmentation.Fashionable the ore deposit rock is carried out fragmentation, then give off broken ore deposit rock when opening.Decide jaw and moving jaw plate as jaw crusher; Gyracone crusher decide awl and eccentric rotating mantle.Since the structures shape of disintegrating machine itself granularmetric composition of the ore deposit rock that is broken undesirable, promptly discharge port opens the moment of discharging, has unavoidably greater than nesting population size, without abundant discharging than coarsegrain ore deposit rock of fragmentation thereupon.For the fine crushing machine, the performance of next process ball mill production capacity will be hindered seriously.

For various disk fixed roller mills and disk rotation roller mill, the roller mill that provides as United States Patent (USP): US 03083920, be that material is placed in the groove on the disk, by applying pressure to the rolling of the running roller on the disk, material is carried out grinding repeatedly, after making material reach certain fineness, carry by strength and to discharge from top.Because the running roller of this type of roller mill all is passive revolution, and the strength and stiffness of its bolster and bearing are subjected to the restriction of structure, be difficult to improve, so this kind roller mill can not broken tough and tensile ore deposit rocks, can only be used for the soft material of grinding, as coal dust, clinker etc.

The utility model is that design in the deficiency of analyzing above-mentioned two kinds of existing broken, grinding technologies a kind of both can the broken tough and tensile ore deposit of high strength high efficiency rock, can make the thin and breaking machine with roller and disk uniformly of crushed product size again.

The utility model is realized by following manner.The broken disk that has a level to install in the disintegrating machine lower body in the upper machine body of disintegrating machine, near the position of broken disk, is furnished with several broken running rollers along its circumference five equilibrium.They are driven by prime mover and drive disk assembly respectively.Geometry to broken disk, broken running roller and upper machine body inner surface all is designed to certain tapering, and the three cooperates the crusher chamber that constitutes this machine.Gap and pressure between broken running roller and the broken disk can perhaps by being contained in the pressure that hydraulic means produced of lower body bottom center, be adjusted via the support vertical pivot of broken disk by being contained in the spring of lower body joint portion.When material enters crusher chamber by batch meter, under the synergy of the bite force that gravity, centrifugal force, broken running roller and broken disk produce because of move toward one another, material is forced to engaging-inly push, crooked, shear and grind, become thin and uniform product, fall from the periphery of broken disk, discharge by the discharge gate of lower body bottom or sidepiece again.In order to adapt to the broken requirement of different ore deposits rock, the conical surface of broken disk and broken running roller can be made light, with groove or stud with hard-metal insert.The quantity of broken running roller generally is evenly to distribute at circumferencial direction to install three, can be according to the character of the ore deposit rock that is broken and the suitable quantity that increases and decreases broken running roller of size of disintegrating machine.

The utility model has absorbed the design feature of gyratory crusher and gyratory crusher good integrity, the corresponding joint portion of back shaft, bearing and the body of broken disk and broken running roller all has very high intensity and rigidity, can obtain very big crushing force, thereby make machine on the basis that guarantees high productivity ratio, carry out fine crushing tough and tensile ore deposit rock.

Below in conjunction with a description of drawings embodiment of the present utility model.

(1) is to the ore deposit funnel among the figure; (2) be upper machine body; (3) be the running roller motor; (4) be broken running roller; (5) be crusher chamber; (6) be broken disk; (7) be transmission device; (8) be motor; (9) be splined shaft; (10) be hydraulic means; (11) be gape; (12) be lower body.

The broken disk (6) that has a level to install in the inside of upper and lower body (2), (12), the bottom of broken disk (6) is connected with motor (8) by splined shaft (9), drive transmission device (7), three broken running rollers (4) evenly distribute above the circumference at broken disk (6), together form crusher chamber (5) with upper machine body.Each broken running roller (4) drive by a running roller motor (3) and with broken disk (6) move toward one another.Hydraulic means (10) is equipped with in bottom at the lower body (12) of splined shaft (9) lower end, the pressure that hydraulic means (10) is produced is delivered on the broken disk (6) by splined shaft (9), in order to adjust the gap and the pressure of broken running roller (4) and broken disk.When disc motor (8) and running roller motor (3) startup, broken disk (6) and broken running roller (4) i.e. be rotation in opposite directions, to give fragmentation from the ore deposit rock of dropping in the crusher chamber (5) for ore deposit funnel (1), fall, the ore deposit rock be discharged from gape (11) along the periphery of broken disk (6).

The advantage of breaking machine with roller and disk of the present utility model is: can effectively carry out fine crushing to tough and tensile ore deposit rock, and obtain preferably product granularity, its thin broken product granularity is below 10mm, compare with existing tough and tensile ore deposit rock thin broken technology, can boost productivity 0.5～1 times, be more satisfactory disintegrating apparatus in the systems such as metallurgy, mine.
