Box crusher

Brief introduction

The box crusher has a high rotor speed and a large hammer moment of inertia, fully reflecting the advantages of using large crushing to small crushing and heavy crushing to light crushing. With a large crushing ratio, it can achieve complete crushing in one go, replacing traditional two-stage or three-stage crushing. This equipment has the characteristics of energy saving, high crushing ratio, large feed particle size, uniform discharge particle size, less over crushing phenomenon, compact structure, and convenient maintenance and replacement of vulnerable parts. The crushing of limestone, rock, gypsum, coal gangue and other materials with a compressive strength not exceeding 200 megapascals can be widely used in various quarries, stone production lines, sand production lines, and mineral crushing equipment.

Working principle

When the box crusher is in operation, the stone material falls directly into the high-speed rotating turntable from the upper part of the machine. Under the action of high-speed centrifugal force, it produces high-speed impact and high-density crushing. After passing through the hammer heads of the box crusher and hitting each other, the stone material will form vortex motion between the turntable and the casing, causing multiple mutual impacts, friction, crushing, and finally crushing to the required particle size.

Performance characteristics

1. The box crusher achieves coarse and medium crushing in one step, simplifying the process flow.

2. The box crusher case can be flipped, and the hammer shaft installation is adjustable, making maintenance more convenient.

3. The box is resistant to impact and wear, with high output, low supporting power, low energy consumption, fewer vulnerable parts, and stable performance.

4. The feed particle size is large, the crushing ratio is high, the discharge is uniform, and the yield is high. Granular products account for about 85%, fully meeting the usage requirements.

5. The box crusher adopts high wear-resistant material hammers (each pair of hammers can crush 30000 to 40000 tons of stone), grate plates and impact plates, and hammers with a long service life, controllable product particle size, and good particle shape.
