Description

Technical Field

[0001] The invention relates to the technical field of steel slag grinding, in particular to a steel slag grinding device. Background Art

[0002] Steel slag contains a large amount of heavy metals and harmful substances. If not properly handled, it will cause serious pollution to the environment. The steel slag ball mill uses grinding media (such as steel balls, steel bars or gravel) to impact and grind the materials to achieve material crushing. Its working principle is to feed the raw materials into the hollow cylinder through the hollow shaft neck for grinding. The cylinder is filled with grinding media of various diameters. When the cylinder rotates around the horizontal axis at a certain speed, the media and raw materials in the cylinder are ejected or rolled down after reaching a certain height under the action of centrifugal force and friction, and the ore is crushed due to the impact force. At the same time, the sliding movement between the grinding media also produces a grinding effect on the raw materials.

[0003] However, when conveying steel slag into the ball mill, due to the different particle sizes of steel slag, fine particles are more likely to be suspended in the air, and the steel slag collides with each other when falling into the upper hopper, causing dust to fly; in addition, during discharge, the particle size of the ground steel slag becomes smaller, and it is more likely to generate dust when discharged into the storage box. Operators located near the storage box are prone to inhale dust into their mouths and noses, posing a health hazard; when the ball mill is fed too much or the feed volume is large in a short period of time, the grinding body cannot fully grind the excessive material, which can easily lead to uneven particle size of the ground steel slag. The different particle sizes of steel slag can easily affect its utilization efficiency in subsequent use, which is not conducive to improving the use effect of the ball mill.

The feeding mechanism can be opened to convey the slag into the cylinder of a ball mill. The dust generated during feeding can be suppressed by a spraying mechanism, that is, the slag to be ground is conveyed into a feeding hopper by a feeding machine. The feeding hopper is fixedly mounted on the side wall of a feeding pipe and is connected to the inside of the feeding pipe. The slag is discharged into the feeding pipe through the feeding hopper. A fixing frame is fixedly mounted on the side wall of the feeding hopper. A limiting rod fixed at the bottom end of a supporting seat is mounted in the fixing frame. Water is conveyed into a drainage pipe mounted in a card plate through a water pipe. Water is then sprayed out through a nozzle fixed at the end of the drainage pipe. Water particles are suspended in the air to form fine particles. Small water droplets physically collide with the suspended particles to wet the particles.

The discharge hopper is connected to the storage mechanism, so that the ground steel slag can be sealed and discharged into the storage mechanism for storage. That is, the motor installed on the base drives the ball mill cylinder to rotate, so that the grinding media (such as steel balls) installed in the ball mill cylinder produce rotation, falling and other movements, thereby impacting and grinding the steel slag. The collision and friction between the steel balls and the steel slag will generate force, which will break the chemical bonds and crystal structure inside the steel slag, thereby achieving a crushing effect, thereby crushing larger steel slag blocks. into smaller particles; the ground steel slag ball mill cylinder is transported to the discharge pipe, on which a discharge hopper is fixedly installed. Since the end of the discharge hopper is arranged in an inclined structure, the steel slag can be discharged into the storage box through the discharge hopper; clamping rods are fixed on both sides of the discharge hopper, and the storage box is engaged with a clamping frame installed at the bottom of the box cover, and a clamping block is fixed on the box cover, and the clamping block is engaged with the clamping rod.

When the control switch of the hydraulic rod is turned on, the telescopic end of the hydraulic rod is in resistance to the resistance rod when it moves, and a telescopic spring is sleeved on the resistance rod. The telescopic end of the hydraulic rod is in resistance to the resistance rod, so that the resistance rod squeezes the telescopic spring when it slides in the material storage box. When the telescopic spring is in a compressed state, the resistance rod can drive the screen to move, and the hydraulic rod is reset, and its telescopic end is separated from the end of the resistance rod. Under the reaction force, the resistance rod is reset, and its top end is separated from the screen. The screen hits the resistance rod under the action of the gravity of the slag, and when the screen shakes in the storage box, the slag with larger particles can be filtered and screened.
