Description

The invention relates to cone inertial crushers and can be used in powder metallurgy.

Known cone eccentric crusher medium and fine crushing, comprising a housing with a control ring, an outer cone and a spherical support for the inner cone, the shaft of which is located inside the eccentric drive sleeve mounted in the bearings of the housing. The crusher has a liquid circulation lubrication system for bearings of the drive shaft, eccentric assembly, spherical thrust bearing and bevel gear [And ·

In this eccentric crusher, it is impossible to crush and, even more, grind metal materials, since the ingress of impenetrable inclusions into it can lead to an accident causing a long idle time of the machine.

Closest to the technical nature of the invention is an inertial cone crusher containing a bed with an adjusting ring, an outer cone and a spherical bearing for an inner cone with a shaft, on the shank of which there is a drive unbalanced vibrator having a transmission with bearing bearings in the housings, and means for supplying chilled fluid lubrication and friction units.

When grinding minerals or metal chips to cool a known crusher, it is sufficient to use circulating lubricant and a refrigerator mounted at the oil station and equipped with a supply of cooling water. In this case, normal cooling of liquid lubricant and bearing assemblies is achieved [2].

However, when grinding highly alloyed metal granules, the discharge gap during operation is close to zero, therefore, the material being crushed does not have time to carry away the heat generated during its destruction under conditions of very low productivity. At the same time, the work on the destruction of such a material (bv = 350 kg / mm ² ) requires the consumption of almost the full installed power of the engine, so the existing cooling means are insufficient and do not provide conditions for the continuous operation of the machine.

The purpose of the invention is to increase the reliability of the crusher when grinding heavy-duty materials.

This goal is achieved by the fact that a cone inertial crusher containing a bed with a regulating ring, an outer cone and a spherical bearing for an inner cone with a shaft, on the shank of which there is a drive unbalanced vibrator having a transmission with bearing supports in the housings, and means for supplying cooled liquid lubricant to the friction units, equipped with a system of additional cooling of the friction units, made in the bodies of the regulating ring, spherical bearing and bearing housing, in the form of a ring outlet flow cavities for a cooling medium.

The drawing shows a cone inertial crusher, a longitudinal section.

The crusher contains a frame 1, on which a control ring 2 with an annular tight cavity 3 and an outer cone 4 is placed. A spherical support 5, equipped with an annular tight cavity 6, is fixed on the frame. An inner cone 7 with a shaft 8 is placed on the support 5, on the shank of which of the bearing 9, an unbalance 10 is mounted, connected by the transmission '11 to the electric motor 12. The bearing 13 of the transmission 11 is located in the tide 14 of the frame 1, equipped with an internal annular tight cavity 15.

Each of the cavities 3, 6, and 15 is equipped with fittings 16–18, respectively, for supplying coolant, for example, water, to them, which are combined into one line 19. Cavities 3, 6, and 15 are also equipped with fittings 20–22 for water drainage, combined into a common highway 23.

When the crusher is operated by rotating the unbalance 10, a centrifugal force is created, causing the inner cone 7 to gyrate on the spherical support 5 and destroy the material fed into the chamber formed by the cones 7 and 4. The cooling water circulating in the cavities 3, 6 and 15, removes heat from crushing bodies, which ensures the continuity of the crushing process without stopping the crusher for cooling.

The economic effect is achieved by reducing more than half the required number of crushers to ensure a given performance, reduce the area and reduce operating costs.
