Description

High Frequency Vibration Crusher

technical field

The utility model relates to a crushing device for hard materials, in particular to a high-frequency vibration crusher.

Background technique

As the mine crushing process, the crushing equipment widely used in the primary crushing stage mainly includes jaw crushers, hammer crushers, ring hammer crushers, impact crushers, roll crushers, and cone crushers. It is a vertical shaft crusher, etc. All of the above equipment have their own characteristics. For example, the jaw crusher is a traditional crushing equipment, mainly used as primary and secondary crushing equipment; roller crusher, cone crusher, hammer crusher , Ring Hammer Crusher, and Impact Crusher are mainly used as secondary and fine crushing equipment, such equipment generally has low efficiency; Vertical Shaft Crusher is mainly suitable for crushing soft materials in non-metallic ore, and this type of equipment is difficult to maintain.

Crushing and grinding operations consume a lot of energy and steel. It accounts for more than 65% of the total consumption of factories and mines, and some are as high as 85%. Therefore, from the perspective of the importance of production and economic benefits, it is of great practical significance to study and improve crushing and grinding methods and processes, and to explore and develop new high-efficiency crushing and grinding equipment for reducing costs and improving benefits.

The application of vibration crushing technology in industrial production has achieved huge social and economic benefits. With its application in industry, it has gone through a process of development, perfection and maturity, but the development of vibration crushing technology is far from Stop, especially for crushing techniques that utilize vibration. The application of vibration crushing is very extensive, especially in the field that the conventional crusher cannot solve at present, it has found a more suitable position. Such as vibrating jaw crusher, vibrating roller crusher, and inertial cone crusher, the production efficiency has been greatly improved, and they have been applied in some industries. Roller crusher is one of the oldest crushing equipment, because it has the advantages of simple structure, light weight, reliable operation, low price, uniform product size, less over-grinding, etc. In building materials and other industries, it is still widely used as medium and fine crushing equipment. Its disadvantages are low production efficiency, high power consumption, fast and uneven wear of the roller surface, and the impact on the crushing effect.

Apply vibration crushing technology to roller crushers to solve the problems of small production capacity, uneven wear of the roller surface and process adaptability. At present, it is mainly used in single-roll or double-roll crushers, but the vibration frequency is not high or the production capacity is too high. Small.

In order to achieve the above purpose, the technical solution provided by the utility model is: a high-frequency vibration crusher, including an organic base, a feeding device, a discharging device, an upper fixed roller, a lower fixed roller, a vibrating roller, a vibrator, Swing frame and damping device;

The base is provided with two supporting angle frames, wherein the upper and lower supporting angle frames on the right are respectively provided with an upper fixed roller and a lower fixed roller, between the upper fixed roller and the lower fixed roller is a vibrating roller, and the vibrating roller The vibration exciter is installed under the bottom, and the vibration roller and the vibration exciter are fixedly installed on the swing frame;

The hinge ear on the upper part of the swing frame is hinged with the hinge seat on the support angle frame on the left side of the machine base, and the lower part of the swing frame is provided with a damping device;

The outlet of the feeding device is arranged between the vibrating roller and the upper fixed roller, and the below of the vibrating roller and the lower fixed roller is a discharge device.

A motor and a transmission distribution box are arranged on the side of the machine base, and the output end of the transmission distribution box is respectively connected with the central shaft of the upper fixed roller, the lower fixed roller, the vibrating roller and the vibration exciter through a universal coupling.

Both the upper fixed roller and the lower fixed roller are connected to the support angle frame on the right so as to move up and down.

The left support angle frame is connected to the base so that it can move left and right.

The roller surface of the upper fixed roller can be made into a smooth surface, a textured tooth-shaped non-smooth surface or a corrugated non-smooth surface in order to adapt to the crushing of various materials.

The gap between the vibration roller and the upper fixed roller is larger than the gap formed between the vibration roller and the lower fixed roller. The adjusted gap between the vibrating roller and the upper fixed roller can be changed during work, but the adjusted gap between the vibrating roller and the lower fixed roller does not change.

The damping device can be set as compression spring, air spring, hydraulic spring or composite spring composed of compression spring and rubber.

The utility model has the advantages of solving the problems of low production efficiency, high power consumption, fast and uneven wear of the roller surface and the impact on the crushing effect of the existing roller crusher.

1. The gap between the upper fixed roller, the lower fixed roller and the vibrating roller can be adjusted separately. Adjusting the upper fixed roller to move up and down can change the gap between the upper fixed roller and the vibrating roller. Adjusting the lower fixed roller to move up and down can change the lower fixed roller. The gap between the roller and the vibrating roller can be adjusted by adjusting the support angle frame on one side of the swing frame and moving left and right to change the gap between the upper fixed roller, the lower fixed roller and the vibratory roller at the same time. In this way, the service life of each roller can be extended to the maximum extent.

2. The damping device can be set as a compression spring, an air spring, a hydraulic spring or a composite spring composed of compression spring and rubber, etc., and the damping coefficient or the eccentric weight on the exciter can be adjusted to adjust the vibration crushing force and crushing effect. This achieves different crushing effects.

3. The roller surface of the upper fixed roller can be made into a smooth surface or a non-smooth surface such as textured tooth shape and wave shape to adapt to the crushing of various materials.

4. The rollers are driven separately to form different speed ratios to adapt to the crushing of various materials.

5. The crushing cavity formed between the upper fixed roller, the lower fixed roller and the vibrating roller uses the principle of vibration and impact to crush materials. In the crushing cavity, the materials are subject to the combined action of impact, extrusion and shearing forces, so the energy consumption is low, the wear is small, the roller surface wears evenly, and the efficiency is high, and the crushing effect on hard and brittle materials is more significant.

6. During the high-frequency vibration of a certain amplitude around the center of the hinge shaft, the impact force on the materials in the crushing cavity between the vibrating roller and the upper fixed roller, and between the vibrating roller and the lower fixed roller is large at the top and small at the bottom. It just adapts to the requirements of materials from coarse crushing to fine crushing, which improves the production capacity.

7. Each roller is an assembled structure, which is convenient for maintenance and replacement of worn parts.
