Product Overview: PF Series Impact Crusher

PF series impact crusher is a new generation of medium and fine crushing equipment which is developed by our company by integrating the advanced technology from home and abroad and closely combining with the actual working conditions of domestic sand and gravel industry. With unique structural design and high quality wear-resistant materials, it can efficiently crush all kinds of medium-hard materials (such as granite, limestone, concrete, etc.) with compressive strength not exceeding 350MPa, and the maximum feed size can reach 500mm, and the crushed particles are in the form of cubic shape, uniform particle size, no tension cracks, and excellent granularity, which is the ideal choice for the production of high-grade aggregates. It is widely used in ore crushing and material shaping in mining, building materials, railroad, highway, energy, cement, chemical industry and so on.

Working Principle

After the material enters the crusher, driven by the high-speed rotor, the plate hammer impacts the material violently and makes it hit the impact plate at high speed to realize the first crushing. After the impact, the material bounces back to the plate hammer area and is impacted again, and collides with other splashed materials. This process is repeated in the first, second and third level impact chamber, until the material is repeatedly impacted, collision crushing to the required size, and finally discharged from the discharge port. By adjusting the gap between the counterattack frame and the rotor, the discharge size can be flexibly controlled.

Core Advantages and Features

• 🎯 Excellent granularity of finished products: adopting the principle of impact crushing, the materials are subjected to multiple impacts and friction in the cavity, and the finished products are mostly cubic, with low content of needles and flakes, and high value of the products, which fully meet the standard of high-grade aggregates.

• ⚡ Huge crushing ratio and high efficiency capacity: deep cavity design, large rotor moment of inertia, abundant impact energy, large crushing ratio, can simplify the crushing process, high single-machine handling capacity, significant production efficiency.

• 🛡️ Core components are sturdy and wear-resistant: the key crushing component, plate hammer, is made of high chromium alloy, which has extremely high wear resistance and impact toughness, long service life, and reduces the operation and maintenance cost.

• 🔧 Easy operation and maintenance:

  • Keyless connection: the rotor and plate hammer are fixed by mechanical locking, and it is more convenient, fast and reliable to replace the plate hammer.

  • Adjustable gap: the gap between the counterattack frame and the plate hammer can be easily adjusted by mechanical device, so as to accurately control the product size and meet diversified needs.

• 🏗️ Compact structure, strong rigidity: the whole machine has a compact design and good rigidity. The rotor is calibrated by precise dynamic balance, running smoothly and with high reliability, especially suitable for continuous operation of production line.

Technical Parameter Table

Note: The processing capacity is closely related to the hardness, humidity, composition and final product size requirements of the material, the data in the table is the reference range for medium hardness materials.

Applicable materials and fields

• Applicable materials: limestone, lapis lazuli, calcite, dolomite, coal, calcium carbide, slag, construction waste (concrete), ores below medium hardness and other hard and brittle materials.

• Unsuitable materials: extremely high hardness (such as basalt, river pebbles) or sticky materials will cause serious wear and tear on the hammer and impact plate.

• Application field:

  • Mining industry: medium crushing and fine crushing of ores.

  • Building materials and aggregates: production of high-quality mechanism sand and various specifications of stone.

  • Construction industry: construction waste resource recycling treatment.

  • Cement and chemical industry: crushing pretreatment of raw materials.
