Abstract

The utility model relates to rock crushing equipment, namely, a centrifugal crusher, which is capable of grinding materials effectively without using grinding balls. The utility model is composed of a machine frame, a fixed axle, hollow minor axles, an electromotor, a belt pulley, working chambers, casings, feed hoppers, discharge devices, etc., wherein, the fixed axle is provided with the two rotary hollow minor axles provided with the working chambers; the two hollow minor axles and the working chambers are installed symmetrically and rotate in reverse direction; the outer sides of the two working chambers are provided with the casings provided with the feed hoppers and the discharge devices.

Description

A kind of centrifugal crusher

The utility model relates to a kind of equipment of fractured rock, i.e. centrifugal crusher.

At present in the ore grinding process, be extensive use of ball mill, abrading-ball and rock piece promptly are housed in the metal cylinder of a bigger garden cylindricality, the garden column casing rotates around axis slowly, abrading-ball is behind the inwall rising certain altitude of tube, fall a rock piece and smash, from an endfeed of garden tube, continuous from other end discharging.Because the adding of milling medium iron ball, thus iron ball dust is many when falling, noise is big, iron ball consumption is many, the body bulkiness, power consumption is big, causes the cost raising.

The purpose of this utility model is to overcome in the working chamber and adds a series of shortcoming that abrading-ball brought, and a kind of equipment that also material effectively can be ground without abrading-ball is provided.

The utility model is by frame, fixed axis, hollow minor axis, motor, belt pulley, working chamber, casing, feed hopper, drawing mechanisms etc. are partly formed, fixed axis is installed on the frame, two rotating hollow minor axises are housed on it, the exterior wall of hollow minor axis is being adorned belt pulley, link by belt and motor, the other end is installed with working chamber, there are charging hole and discharge opening in the working chamber both sides, two hollow minor axises and working chamber symmetry are installed, and do reverse rotation under driven by motor, in the outside of two working chambers, casing is housed on the support, feed hopper is arranged on the casing, communicate, also have drawing mechanism on the casing with the charging hole of working chamber.Material enters two working chambers from the feed hopper of casing both sides, in the working chamber of rotation, material each other, material and chamber wall bump, after material throws away from working chamber, at the approaching place of the working chamber of two reverse rotations, be the blow tank place, produce collision again, rush at the inwall of casing then at a high speed, collision again, by this a series of collision, material can be milled to more than 400 orders, and can adjust fineness according to the needs of production technology.

Advantage of the present utility model is to have saved abrading-ball, and the grinding machine volume of identical production capacity can dwindle greatly, thereby energy savings, saves the abrading-ball steel, reduces the disintegrating machine floor space, reduces noise.

Fig. 1 is that the utility model embodiment faces structural representation.

Fig. 2 is embodiment A-A profile.

Fig. 3 is Embodiment B-B profile.

Introduce embodiment below in conjunction with accompanying drawing: fixed axis (2) is installed on frame (1), symmetry is equipped with two hollow minor axises (3) on it, hollow minor axis can be gone up at fixed axis (2) by bearing (4) and bearing (5) and rotate, belt pulley (6) is equipped with by key in the outer end of hollow shaft (3), link by belt (7) and motor (8), the other end is the working chamber of hollow frustum shaped, working chamber is by garden platform cambered surface (9) and outer garden face (10), garden shape sieve plate (11) is formed, their three's welderings are one, there is garden shape charging hole (12) in the centre of outer garden face (10), many equally distributed discharge openings (13) are arranged on the periphery of garden shape sieve plate (11), garden shape sieve plate (11) is fixed on the hollow minor axis (3) by ring flange (14), thereby working chamber can be rotated with hollow minor axis (3), the working chamber inwall, it is the inner surface of garden platform cambered surface (9), be welded with iron bar (15) along what the bus of garden table top was interrupted, working chamber is by motor (8), by belt (7), belt pulley (6), hollow minor axis (3) drives, two working chamber symmetries are installed, do reverse rotation, two working chamber outsides, casing (16) is housed on the support (1), there is feed hopper (17) to communicate on the casing, also has drawing mechanism (18) on the casing with the charging hole (12) of working chamber.Material enters working chamber from the feed hopper (17) of casing both sides by charging hole (12), advancing bucket material is the granite stone of φ 10mm, in the process of working chamber rotation, material is mutual, material and working chamber wall bump, because the garden table top (9) of working chamber is the inclined-plane, so material is subjected to the promotion of working chamber wall, throw away by discharge opening (13), is that collision is located and produced to blow tank (19) at the working chamber of two reverse rotations near the place, rushing at casing (16) inwall at a high speed then collides again, by this a series of collision, material can be milled to 300 to 400 orders, and can adjust fineness according to the needs of production technology, for increasing the wearability of casing (16), abrasion-proof backing block (20) is housed in part near blow tank (19).

Claims
