[0002] With the rapid development of industry, the amount of slag is huge. Slag contains a large amount of valuable components, such as iron, calcium, silicon, etc. If discarded directly, not only a large amount of land resources are occupied, but also resources are wasted. The slag recovery crushing device for slag micro-powder production recycles and processes slag, which is converted into slag micro-powder, which can be used as cement admixture, concrete additive, etc. to realize the recycling of resources and improve the utilization efficiency of resources. In the construction industry, slag micro-powder has good activity and filling effect, which can improve the performance of concrete, such as strength, durability, impermeability, etc. At the same time, it can also reduce the cost of concrete. With the continuous development of the construction industry, the demand for slag micro-powder is increasing, which requires efficient slag recovery crushing devices to ensure the production quality and yield of slag micro-powder.
[0003] Ball mill is a commonly used equipment in slag micro-powder production. Inside it is equipped with grinding bodies. When the mill cylinder rotates, the grinding bodies are lifted to a certain height under the action of centrifugal force and friction and then fall, impacting and grinding the slag in the cylinder. Under the continuous impact and grinding action of the grinding bodies, the slag is gradually crushed into fine particles, eventually reaching the particle size of micro-powder.
[0004] During the crushing process of slag micro-powder, friction and collision occur between slag particles and steel balls, causing some fine particles to separate from the main body and form dust. Long-term inhalation of slag dust may cause damage to the respiratory system and lead to occupational diseases such as pneumoconiosis, endangering the health of operators. UTILITY MODEL CONTENTS

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0018] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to the connection method that allows movement through connecting parts such as hinges, pins, and short shafts.
[0019] The present invention will now be described in detail with reference to the accompanying drawings.
[0020] The following is in conjunction with the appendix Figs. 1-3 This embodiment describes a slag recycling and crushing device for slag powder production, comprising: a crushing shell 1, a feeding pipe 2 connected to the top wall of the crushing shell 1, an input shaft 3 rotatably connected to the bottom wall of the crushing shell 1, a turntable 4 connected to the upper end of the input shaft 3, the turntable 4 being located inside the crushing shell 1, a center block 5 connected to the turntable 4, a blade 6 connected to the upper surface of the turntable 4 and the side of the center block 5, the blade 6 having an inclination angle, multiple steel balls provided on the upper part of the turntable 4, a slag suction pipe 7 provided on the upper part of the turntable 4, the slag suction pipe 7 being connected to the top wall of the crushing shell 1, and the slag suction pipe 7 being connected to a vacuum pump.
[0021] In operation, slag is injected into the crushing shell 1 through the feed pipe 2. The input shaft 3 is turned on, and the power drives the turntable 4 and the blades 6 to rotate. The inclined blades 6 cause the steel balls and slag to rise along the inclined surface of the blades 6. The steel balls and slag are repeatedly lifted and fallen. During the friction and collision with the steel balls, the slag particles are crushed into fine powder. The air pump draws the powder into the crushing shell 1 through the slag suction pipe 7. The qualified fine powder is collected by the air pump through the slag suction pipe, while the unqualified slag continues to be crushed. In this way, the fine powder will not spread and generate dust, which solves the problem of fine powder hazarding the health of operators.
