There are significant differences between jaw crushers and hammer crushers in many aspects:
1. Working principle:
• The working principle of the
jaw crusher is that the movable jaw plate makes periodic reciprocating motion to the fixed jaw plate, and the materials are squeezed and crushed in the crushing cavity composed of the movable jaw and the fixed jaw.
• The
hammer crusher mainly relies on the impact, shearing, and tearing of the rotating hammerhead, as well as the mutual impact between materials and the counterattack of the lining plate for crushing.
2. Crushed materials:
• Jaw crusher can crush various soft and hard materials, with a compressive strength between 300-350Mpa, such as granite, quartz stone, diabase, river pebbles, iron ore, etc.
• Hammer crusher is mainly used to crush ores with low hardness, whose compressive strength is generally lower than 200Mpa, such as limestone, bluestone, coal gangue, etc.
3. Discharge adjustment method:
• Jaw crushers usually use a gasket-type discharge opening adjustment device. This device is reliable and convenient, and has a large adjustment range, which increases the flexibility of the equipment.
• The hammer crusher adjusts the discharge particle size by replacing the bottom screen plate.
4. Structure and Maintenance:
• Jaw crusher has the characteristics of simple structure, reliable operation, easy maintenance, and economical operating costs. Its lubrication system is safe and reliable, parts replacement is easy, and maintenance workload is small.
• The hammer crusher has the advantages of a beautiful overall design, compact structure, few wearing parts, and easy maintenance. Its working hammer head is cast using a new process and is wear-resistant and impact-resistant.
5. Applicable scenarios:
• Due to its high crushing ratio and large output, the jaw crusher is often used for primary crushing in industrial and mining production and is an important member of the mining crushing equipment.
• The hammer crusher is suitable for crushing materials with medium hardness and below. It has high crushing efficiency and low cost, making it an ideal choice in many industries.
6. Noise and Dust:
• Jaw crushers are often designed with low noise and dust reduction features to help improve the working environment.
• Hammer crushers are also designed to reduce noise and dust, but their effectiveness may vary depending on the specific model and application.
To sum up, there are significant differences between jaw crushers and hammer crushers in terms of working principles, crushed materials, discharge adjustment methods, structure and maintenance, applicable scenarios, and noise and dust. When selecting a crusher, it is necessary to comprehensively consider factors such as specific production needs, material characteristics, and working environment.
