1. Crushing particle size control The raw ore needs to be crushed to a size of 20-50mm to ensure that the physical state of the ore is suitable for the fine grinding requirements of the subsequent grinding stage. This particle size range can not only reduce the energy consumption of grinding, but also provide a reasonable basis for mineral dissociation. 2. Crushing process design Generally, a closed-loop crushing process is adopted: The first crushing uses SBKT jaw crusher for coarse or medium crushing; the second crushing uses SBKT cone crusher or hammer crusher for medium and fine crushing. The product needs to be graded by SBKT vibrating screen. The material on the screen returns to the crusher for further processing, and the material under the screen enters the ore storage bin to wait for grinding, forming a closed-loop control. 3. Equipment selection requirements Coarse crushing equipment: SBKT jaw crusher is preferred, which has strong ability to process large ore and stable structure; Medium and fine crushing equipment: SBKT cone crusher (high hardness) or SBKT hammer crusher (medium and low hardness) is selected according to the hardness of the ore; Shengbang Machinery will equip you with a vibrating screen that matches...

1. Definition and Structure The jaw crusher (also known as jaw crusher, tiger mouth) is a mechanical device with a crushing chamber composed of two jaw plates, the movable jaw and the static jaw, which completes the extrusion and crushing of materials by simulating the periodic movement of the two jaws of animals. Its core components include the frame, eccentric shaft, movable jaw plate, fixed jaw plate, toggle plate, flywheel and gap adjustment screw, etc. The crushing chamber adopts a trapezoidal design with a large upper part and a small lower part, in which the toggle plate also has a safety function. 2. Working Principle The jaw crusher is driven by a motor-driven pulley to drive the eccentric shaft to rotate, so that the movable jaw periodically approaches or moves away from the fixed jaw. When the movable jaw rises, the material is squeezed, crushed and crushed between the two jaws; when the movable jaw descends, the crushed material is discharged by its own weight. Continuous crushing operation is achieved. The deep-cavity jaw crusher can improve the processing capacity (10-100 tons/hour) and reduce energy consumption by optimizing the cavity design.The jaw crusher is driven by a motor-driven pulley to drive...

Jaw crusher is often used for coarse crushing, suitable for various ores with compressive strength not higher than 320MPa, such as river pebbles, granite, basalt, iron ore, etc. Large stones below 1m2 can be fed directly.

The river pebble crushing and sand making production line mainly includes crushing, sand making, screening, feeding, conveying, sand washing and control system, etc.

At the construction site or demolition operation, effective garbage classification is first carried out. Construction waste is usually divided into several categories such as concrete, bricks and tiles, wood, metal, plastic and other sundries.

Copper ore is generally a collection of copper sulfide or oxide and other minerals, which reacts with sulfuric acid to produce blue-green copper sulfate.
