Description

TECHNICAL FIELD

[0001] The utility model relates to the field of wet metallurgy crushing technology, especially to a material crushing device for wet metallurgy. BACKGROUND

[0002] Wet metallurgy crushing device is an important link in the process of mineral processing and metal extraction, and its core goal is to crush the ore to a particle size range suitable for subsequent chemical leaching or dissolution. In the wet metallurgy process, physical crushing of the ore is a key step to ensure efficient reaction, because smaller particle size can significantly increase the surface area, promote the contact of leaching agent with the target mineral, and thus improve the metal recovery rate.

[0003] After retrieval, the utility model patent with the authorization announcement number CN219526751U is a lithium wet metallurgy continuous leaching device, which comprises a reaction chamber, the upper end of the reaction chamber is fixedly connected with a fixing frame, the upper end of the fixing frame is fixedly connected with a crushing chamber, the upper end of the crushing chamber is provided with an inlet, the inside of the crushing chamber is fixedly connected with guide plates at both ends, the outside of the crushing chamber is provided with two second driving motors, the output end of the second driving motor is provided with a crushing roller, the other side of the crushing chamber is provided with a third driving motor, the output end of the third driving motor is provided with a screw rod, the second driving motor and the crushing roller can be used to crush the lepidolite entering the crushing chamber, the third driving motor and the threaded assembly on one side can make the bottom roller crush the lepidolite on the filter screen again, improve the crushing degree, and strengthen the continuous leaching efficiency of lepidolite.

[0004] The device uses a crushing roller and a crushing wheel to realize secondary crushing of the material, and fine particles are prepared. However, the reaction rates of different ores and leaching agents are different. For example, the reaction rate of some ores containing rare metals and leaching agents is low. If fine particles are used, although the initial reaction rate is fast, the leaching agent cannot be fully utilized because the reaction is completed too early, resulting in incomplete leaching. Therefore, coarse particles should be selected for slow-reacting materials, and fine particles should be selected for fast-reacting materials. In view of this, the present application further proposes a material crushing device for wet metallurgy based on the above technical problems. UTILITY MODEL CONTENTS
