Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining machinery technology, and in particular to a micro-slag ore powder crushing device. Background Technology
[0002] In mining production, it is necessary to crush larger pieces of ore to reduce their volume. The equipment commonly used is crushing equipment. The basic structure of such crushers includes a crushing unit driven by a power mechanism. Inside the crushing unit are cutters and a crushing chamber, as well as a feeding unit connected to the crushing chamber. The powder to be crushed is fed into the crushing chamber through the feeding unit, where it can be cut and crushed into smaller particles by the cutters. Mineral powder is a material produced by crushing ore after magnetic separation. It is mainly in powder form and is one of the most important steps in ore processing and smelting.
[0003] However, the cutting head is easily damaged during the processing, and replacement is difficult, time-consuming and labor-intensive. Therefore, this application discloses a micro-slag ore powder crushing device. Utility Model Content
[0004] The purpose of this invention is to address existing problems by providing a micro-slag ore powder crushing device.
[0005] This utility model is achieved through the following technical solution: a micro-slag ore powder crushing device, including a bottom shell, which is installed on a frame, and a top shell is rotatably arranged on the bottom shell. A roller is rotatably arranged in the cavity formed by the bottom shell and the top shell. A plurality of material hammer assemblies are evenly distributed on the roller. One end of the roller is connected to the output shaft of a motor, which is installed on the frame. A discharge cylinder is connected through the bottom shell. A filter screen is arranged at the top of the discharge cylinder. A feeding cylinder is arranged on the top shell on the side opposite to the outlet of the discharge cylinder. A flow plate is arranged at the outer end of the feeding cylinder.
[0006] As a further improvement to the above solution, the hammer assembly includes a boss, which is mounted on the roller. A hammer rod is inserted into the boss, and a slanted groove is provided on the upper part of the hammer rod, through which a hammer head is rotatably connected.
[0007] The rotation of the roller drives the hammer rod to rotate. Under the action of centrifugal force, the hammer head in the inclined groove at the outer end of the hammer rod is thrown out of the inclined groove to crush the ore.
[0008] As a further improvement to the above solution, a baffle is rotatably installed on the outlet of the feeding cylinder;
[0009] The baffle is used to prevent the ore from flying out of the discharge port and injuring people when the hammer is hammered during the crushing process.
[0010] As a further improvement to the above solution, connecting plates are symmetrically arranged along the edges between the bottom shell and the top shell to fix the top shell to the bottom shell and ensure that the cavity between the bottom shell and the top shell is sealed.
[0011] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. Mineral slag is fed into the feeding port at the outer end of the feeding cylinder. The roller is driven by a motor to rotate. Hammer rods are installed on the outer curved surface of the rollers. The hammer head at the end of the hammer rod is thrown out from the inclined groove by centrifugal force to crush the mineral slag in the cavity. After being filtered by a filter screen, it is discharged from the discharge cylinder. In addition, the baffle can prevent the mineral in the cavity from being thrown out during the crushing process of the hammer head. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings.
[0019] like Figures 1 to 6 As shown, a micro-slag ore powder crushing device includes a bottom shell 1, which is mounted on a frame 11. A top shell 2 is rotatably mounted on the bottom shell 1. A roller 3 is rotatably mounted in the cavity formed by the bottom shell 1 and the top shell 2. An end shaft 31 is concentrically mounted at the end of the roller 3. Several material hammer assemblies are evenly distributed on the roller 3. One end of the roller 3 is connected to the output shaft of a motor 4, which is mounted on the frame 11. A discharge cylinder 8 is connected through the bottom shell 1. A filter screen 9 is mounted at the top of the discharge cylinder 8. A feeding cylinder 5 is mounted on the top shell 2 on the side opposite to the outlet of the discharge cylinder 8. A flow plate 7 is mounted at the outer end of the feeding cylinder 5.
[0020] As a further improvement to the above solution, the hammer assembly includes a boss 32, which is mounted on the roller 3. A hammer rod 33 is inserted into the boss 32, and a sloping groove 34 is provided on the upper part of the hammer rod 33. A hammer head 35 is rotatably connected inside the sloping groove 34.
[0021] The rotation of roller 3 drives the hammer rod 33 to rotate. Under the action of centrifugal force, the hammer head 35 in the inclined groove 34 at the outer end of the hammer rod 33 is thrown out from the inclined groove 34 to crush the ore.
[0022] As a further improvement to the above solution, a baffle 6 is rotatably installed on the inlet of the feeding cylinder 5;
[0023] The baffle 6 is used to prevent the ore from being splashed out of the discharge port and injuring people when the hammer 35 inside the cavity is hammered during the crushing process. The baffle 6 prevents the ore from flying out and avoids the occurrence of safety accidents.
[0024] As a further improvement to the above solution, connecting plates 10 are symmetrically arranged along the edges between the bottom shell 1 and the top shell 2 to fix the top shell 2 onto the bottom shell 1, ensuring that the cavity between the bottom shell 1 and the top shell 2 is sealed.
[0025] The working principle of a micro-slag ore powder crushing device: The ore is fed into the feeding cylinder 5 through the feeding port. The ore enters the cavity from the feeding cylinder 5. The roller 3 is driven to rotate by the motor 4. The roller 3 drives the hammer rod 33 and the hammer head 35 to rotate. Under the action of centrifugal force, the hammer head 35 protrudes from the inclined groove 34 at the outer end of the hammer rod 33 and crushes the ore in the cavity. After crushing, the ore is filtered by the filter screen 9 and the ore powder is discharged from the discharge cylinder 8.
[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
