Product Introduction
The working principle of vertical composite crusher is to use plate hammer impact and extrusion to break materials. The general material is added to the finished product from the feed port, and the time in the crushing chamber is only 2 ~ 3s. So the material through the large volume, high output. The crusher has two upper and lower hammer frames, the upper hammer frame has 4 plate hammers, and the lower hammer frame has 6 plate hammers.
The vertical composite crusher is a collection of two crushing material methods in one body: the first reflects the characteristics of the impact crusher, the large material is broken by high-speed impact, and becomes a small piece of material; The second reflects the characteristics of the extrusion machine, small pieces of material after impact, extrusion and broken, the product into powder and small particles; The broken material falls in a rotating motion in the body, so that the material is fully broken. In this way, the material discharged under the impact and extrusion is not the cake, but the loose body of the material. Therefore, the products of the vertical composite crusher do not need to use the breaking equipment.
The rotor component is the key component in the vertical composite crusher. The upper and lower hammer frame is cast as a whole, with good rigidity and balance. The static balance treatment after the rotor assembly further ensures the balance.
The machine is widely used in building materials, metallurgy, mining, coal, chemical and power industries, such as crushing cement clinker, gypsum, limestone, sandstone, blast furnace slag, iron ore, gold ore, molybdenum ore, stone, lump coal, asbestos ore, phosphate rock and other medium hardness materials. For example, the vertical composite crusher using a new type of high chromium alloy plate hammer can break high hardness materials such as river pebbles.

Frequently Asked Questions (FAQ)
Q1: What is the working principle of the vertical composite crusher?
A1: The machine utilizes a combination of plate hammer impact and extrusion. Materials enter via the feed port and undergo high-speed impact and continuous extrusion within the crushing chamber for 2 to 3 seconds, ensuring fast processing and high output.
Q2: What materials can the vertical composite crusher process?
A2: It is widely used for medium-hardness materials such as cement clinker, gypsum, limestone, sandstone, blast furnace slag, coal, and iron ore. By using a new type of high chromium alloy plate hammer, it can also crush high-hardness materials like river pebbles.
Q3: Why does the output material not require additional breaking equipment?
A3: The material falls in a rotating motion inside the body, allowing it to be fully broken down. The discharged material is a loose body of powder and small particles rather than a compressed cake, eliminating the need for extra breaking devices.
Q4: What makes the rotor component of this crusher highly reliable?
A4: The upper and lower hammer frames of the rotor component are cast as a single piece, providing excellent rigidity and balance. Additionally, static balance treatment is conducted after the rotor assembly to ensure smooth and balanced operation.
Q5: What are the main differences between the PLF-1000 and PLF-1500 models?
A5: The PLF-1000 has a cylinder diameter of 1000mm, handles feed sizes ≤80mm, and yields 30-50 t/h. The PLF-1500 has a 1500mm diameter, handles feed sizes ≤120mm, yields 50-70 t/h, and uses a higher motor power of 132kW compared to the 75kW of the PLF-1000.
