The cone crusher was originally designed by the American Simmons brothers and produced by Nordberg. It was popularized around the world in the 1920s and 1930s. After entering the 1980s, the main progress of foreign crushers was the development and strengthening of crushers. After continuous research and improvement, many new cone crushers have been introduced. For example, the United States, Sweden, the United Kingdom, the former Soviet Union, France, Finland, Japan, etc. all introduced new cone crushers with different characteristics in the 1980s to make cone crushers. The development of the machine has taken a big step forward.
HP series cone crusher has the following characteristics:
1. High production capacity. The HP series cone crusher combines higher speed and stroke to greatly improve the rated power and throughput of the HP series cone crusher.
2. High product quality. The inter-particle lamination crushing effect of HP series cone crusher makes the particle size more uniform and the product shape more neat. The HP series cone crusher can produce under a constant discharge port, avoiding that the hydraulic cylinder supports the moving cone and floating up and down during the production process to cause the discharge port to change. By rotating the fixed cone adjustment method, the discharge port is maintained. The constant feed opening improves the stability of the entire production process. In addition, the iron passing protection device can ensure that the crusher can be reset immediately after passing the iron block and maintain a stable discharge port.
3. To reduce downtime, the bidirectional iron-passing release hydraulic cylinder of HP series cone crusher can let iron pieces pass through the crushing cavity. The hydraulic cleaning of the crushing cavity has a large stroke and has nothing to do with the wear of the liner, reducing the amount of work required to remove the blocked materials in the crushing cavity, thereby shortening the downtime. The hydraulic motor drives the fixed cone to adjust the discharge opening. The hydraulic motor can also turn the fixed cone out of the adjusting ring nut to replace the liner, which greatly simplifies the workload of liner replacement. The advanced liner fixing technology improves the reliability of the liner. The fixed cone liner is engaged with the thread slope on the upper part of the fixed cone liner by the wedge to form self-locking; while the movable cone liner is fastened by self-locking locking bolts .
4. It is easy to maintain. The bronze bushing of HP series cone crusher can provide larger load capacity in the crushing environment with large vibration and dust. All parts of the HP series cone crusher can be disassembled and repaired from the top or side, which is convenient for maintenance.
