Technology features 

1. Most Hongxing impact crushers adopt multi-chamber evenly crushing, which is available to hard rocks. 

2. The design is low big feeder, so that production line arrangement is convenient and big size feeding materials is available. 

3. Hongxing impact crusher adopts fully hydraulic crushing design, so that maintainance and replacement is simple and easy. 

4. Wear resistant material prolongs service life of flat hammer, impact liner and liner. 

Structure features 

1. Big feeder, high level crushing chamber, adapted to big hardness materials, big material size is available. And less stone powder in finished products. 

2. Gap between impact board and flat hammer is easy to adjust, it is easy to effectively control discharging partical size and product shape. 

3. Structure of all parts is  compact, which has strong rigidity and larger moment of inertia of rotor. 

4. High chromium board hammer is impact resistant, wear resistant and big impact force. 

5. Keyless connection makes it easy for repairment, which is very economic. 

6. Full crushing functions, high production efficiency, less parts wear, above of all, it is high comprehensive benefits.

Structure design of Singly-rotor impact crusher 

Stone materials are sent into feeder, which installed screen along feeding direction to prevent stone from flying out of feeder. Then the stone materials fall on bar screen, small size materials fall through the grate gap. While big size stone slides on rotor along with screen surface. We installed flat hammers on a certain level around rotor. The materials falling on high speed rotor get huge impact force by flat hammers, and then materials bound onto rotor. Thus, stone will be broken with impact force and bound force. Bar screen, rotor, impact board and screen form the first impact space, and the space between impact board and rotor form the second impact space. Materials will pass through the first and second impact space successively. And finally finished products fall out of discharging opening.  One end of impact board is hung on casing with activity chain, and the other end is fixed with adjuster bolt. When big size stone or some especially hard materials blogged in the gap between rotor and impact board, the impact board will move backward to increase the gap, so that hard materials can get through, thus prevent rotor from being damaged. And then impact board will go back to previous place under deadweight. That is crusher's protection device.
