Product Introduction

Impact crusher is an equipment with the advantages of simple structure, high crushing ratio, low energy consumption, high output, and cubic shape after material crushing. It is mainly used in industrial sectors such as mining, cement, construction, refractory materials, coal, glass, etc., for crushing various materials with medium hardness, such as limestone, clinker, slag, coke, coal, etc.

Advantages

1. Good crushing effect: The PF impact crusher adopts a grate plate design, and the material enters the crushing chamber and collides with the plate hammer on the rotor. Then, it is crushed by the fine crushing chamber, and the crushed iron ore particles are full.

2. Flexible combination: The PF impact crusher can be paired with a mobile crusher to increase the mobility of the equipment. It can walk freely without being limited by the site, easily achieving transfer and improving work efficiency.

3. Can solve materials with high humidity: The feeding chute and impact lining plate of the PF impact crusher can be equipped with heating devices to prevent material sticking, while hammering cannot use heating methods to prevent material sticking.

4. Suitable for a wide range of material hardness: The plate hammer of the PF impact crusher is firmly fixed on the rotor through equipment clamping structure, occupying a large moment of inertia when rotating with the rotor, suitable for crushing harder materials.

5. Convenient adjustment of finished product particle size: The PF impact crusher can adjust the finished product particle size in various ways, such as adjusting the rotor speed, adjusting the space of the impact lining plate, and grinding chamber.

6. The wear of vulnerable parts is small and the metal usage rate is high: The wear of the plate hammer of the PF impact crusher only occurs on the side facing the material. When the rotor speed is normal, the feed will fall to the surface of the plate hammer (impact surface), and the back and side of the plate hammer are not worn. The hammer breaks and the hammer head appears to be hanging, with wear occurring on the top, front, back, and sides. Compared to a plate hammer, the hammer head is more severely worn.

7. Easy replacement of spare parts and low maintenance costs: Only 6 plate hammers are installed on the rotor of the PF impact crusher, and the replacement of plate hammers can be easily done using the tools provided by Zhongyu Dingli Mining Machinery Co., Ltd. The replacement of the grinding rod in the lower grinding chamber can only be completed in a few minutes, greatly reducing maintenance and repair time and costs. More than 100 hammer heads have been broken by hammers, and replacing a set of hammer heads requires abundant funds, labor resources, and high maintenance and repair costs.

Working Principle

The working principle of cone crusher mainly utilizes the principle of crushing materials with impact energy. When the machine is in operation, the stones directly fall into the high-speed rotating turntable from the upper part of the machine, and the rotor rotates at high speed under the drive of the electric motor. The material entering from the feeding port collides with the plate hammer on the rotor, and under the action of high-speed centrifugal force, it collides with another part of the flying stones that are separated around the rotary table in an umbrella shape, resulting in high-speed collision and high-density crushing. The material is crushed by the high-speed impact of the plate hammer, and the crushed material is then counterattacked onto the lining plate and crushed again. After hitting each other, the stones will form eddy currents between the turntable and the casing, causing multiple impacts, friction, and crushing.

Application Area

The impact crusher is a type of equipment suitable for processing materials that often require relocation operations in metallurgy, chemical industry, building materials, water and electricity, etc., especially when dealing with flowing stone materials, it is very efficient.

1. In terms of materials used in highways and railways, the impact crusher can handle various materials with a large crushing ratio, simplified crushing process, and high crushing efficiency.

2. In the field of energy and environmental protection, the impact crusher can meet the requirements for material particle size, improve material utilization and production efficiency.

3. In the field of chemical manufacturing, the impact crusher can crush raw materials into smaller particles, facilitating subsequent processing and production.

4. In the production of cement and building materials, the impact crusher can crush large blocks of raw materials into the required particle size, improving production efficiency and product quality.

5. In the fields of mining and mineral processing, the impact crusher can efficiently crush various ores and rocks, providing suitable materials for subsequent processes such as mineral processing and grinding.
