Metso HP400 Cone Crusher

The Metso Nordberg® HP400™ cone crusher is a mechanical equipment used for crushing ores and rocks. It is suitable for industries such as mining, building materials, and metallurgy. It can perform medium and fine crushing operations on materials of medium and above medium hardness such as iron ore, copper ore, granite, basalt, cobblestone, marble, and limestone. It is preferred in crushing production lines with strict product shape requirements, high yield requirements, and high degree of automation. The following is a detailed introduction to it: - **Structural composition**: Equipped with three hydraulic safety mechanisms: safety cylinder, locking cylinder, and hydraulic push cylinder. Not only do they serve as safety functions, but also enable handling of faults without disassembling machine parts. It can automatically adjust the discharge size, is easy to operate, and has strong reliability. By adopting a special crushing chamber designed based on the principle of interparticle compression and a matched rotational speed, the crushing ratio and output are significantly increased, and the content of finished cubic materials is increased. - **Working principle**: The crushing process of the crusher is completed between the fixed cone liner and the eccentrically moving cone liner. The motor drives the horizontal shaft of the crusher through a V-belt and pulley. The horizontal shaft drives the eccentric shaft through gear transmission. The axis of the crushing cone performs a swinging motion under the drive of the eccentric sleeve, causing the crushing wall and the mantle to approach and move away from each other from time to time. The ore is continuously squeezed, impacted, and bent in the crushing cavity to be crushed. - **Precautions during operation**: - **Inspection before startup**: Before starting up, check whether the connecting bolts of the main components are firm; check whether the crusher cavity is blocked by debris; rotate the coupling to make the eccentric shaft rotate for 2-3 turns to ensure the normal operation of the equipment; check whether the power supply and production water meet the production requirements; check the main equipment, instruments, and pipelines of the lubrication station, and manually operate the electric oil pump to check whether each function is in normal condition; check whether the hydraulic system and locking device are normal; check whether the instruments and switches in the control room are working properly. - **Precautions during operation**: During the operation of the equipment, maintain the balance of incoming and outgoing materials and keep the rated current of the main machine stable to avoid being too large or too small; check the fineness of the crushed product when the equipment is operating normally; the cone crusher is mainly suitable for crushing brittle and medium-high hardness materials. Avoid using it to process overly hard or soft materials. - **Daily maintenance**: Regularly check the wear condition of the equipment and replace wearing parts in time; regularly check the lubrication system to ensure the quality and cleanliness of the lubricating oil; regularly check the hydraulic system to ensure the quality and cleanliness of the hydraulic oil and whether the pressure of the hydraulic system is normal. - **Price**: According to the data of China Construction Machinery Network on March 26, 2021, the price of the Metso Nordberg® HP400™ cone crusher is about 500,000 to 800,000 yuan. The specific price may vary depending on factors such as region and sales channels. When using the Metso Nordberg® HP400™ cone crusher, it is recommended to assign professional personnel to be responsible for the operation of the equipment. Equipment operators are required to operate strictly in accordance with the operating procedures to ensure the normal operation of the equipment and the safety of the operators.
