China Minjie Vertical Crusher for Ore Processing - Efficient, Eco-Friendly Solutions from Leading Suppliers and Factory
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
How does the vertical composite crusher work?
The vertical composite crusher operates by using plate hammer impact and extrusion to break down materials. Materials enter from the feed port and spend only 2 to 3 seconds in the crushing chamber, allowing for high output and rapid processing.
What are the dual-crushing methods utilized in this machine?
The crusher combines impact and extrusion mechanisms. First, large materials are shattered by high-speed impact. Second, these smaller pieces are crushed and extruded into powder and small particles. The falling material rotates inside the body to ensure thorough crushing, meaning no additional breaking equipment is required.
Which industries and materials is this crusher suitable for?
It is widely used in building materials, metallurgy, mining, coal, chemical, and power industries. It handles medium-hardness materials such as cement clinker, gypsum, limestone, sandstone, blast furnace slag, and various ores. When equipped with high-chromium alloy plate hammers, it can even crush hard materials like river pebbles.
What makes the rotor assembly of this crusher reliable?
The rotor is a key component, featuring upper and lower hammer frames cast as a single piece to ensure excellent rigidity and balance. Additionally, static balance treatment is applied after the rotor assembly to guarantee stable, balanced operation.
What are the differences between the PLF-1000 and PLF-1500 models?
The PLF-1000 has a cylinder diameter of 1000mm, handles feed sizes up to 80mm, and has a capacity of 30–50 t/h. The PLF-1500 has a cylinder diameter of 1500mm, handles feed sizes up to 120mm, and features a capacity of 50–70 t/h. Both models utilize a soft startup method.
