Working Principle

Vertical Compound Crusher adopts rock lined rotor that acts as a high-velocity dry stone pump hurling a continuous rock stream into a stone-lined crushing chamber. Material fed into the top of the machine is accelerated in the crusher's rock-lined rotor, achieving exit velocities of up to 50-75 m/s. The rotor continuously discharges into the crushing chamber. This process replenishes the rock lining, while at the same time maintaining the rock-on-rock chain reaction of crushing and grinding. A second stream of material in a controlled quantity can be cascaded into the crushing chamber turbulence causing a supercharging of the particle population within the chamber, improving the energy transfer, to increase the crushing ratio. According to this principle, the material in the chamber is impacted, grinded, and crushed by several times. The crushed material is discharged from the output opening, goes through the screen system, then forms a closed loop. Throughout the whole crushing process, the material impact and crush each other.

Parameters

Features

Large crushing ratio

The maximum feed particle size is 80~240mm, and the output particle size is ≤3mm, accounting for about 90%.

High Yield

The crushing process is straight-through crushing, and the output is high due to the large amount of material passing through and the fast passing speed. Relatively speaking, the energy consumption is less.

Energy efficient

This machine is used in conjunction with the mill, which can increase the output of the mill by about 40%, and reduce the power consumption of the system by about 30%.

Consumable parts wear less and have a long life

The wearing parts are made of high-hardness, high-toughness multi-element alloy wear-resistant material, with less wear and long life. The distance between the hammer head and the impact plate can be fine-tuned to ensure uniform particle size, the utilization rate of the hammerhead is greatly improved, and the service life is increased by about 5 times.

Optimized rotor design

Through the optimized design of the rotor part, this machine forms a multi-stage continuous crushing cavity, which makes full use of energy and space, thereby improving the performance of the machine.

Barrel parts are of open design

It is convenient to replace the vulnerable parts such as the hammer head and the impact plate. Unique throwing tray structure

It is composed of throwing ribs and throwing lining boards, which are distributed in circles. After the throwing ribs are worn out, they can be used as throwing linings, which greatly improves the utilization rate of materials and reduces the cost of use.

Application cooling system and bearing temperature detection device

It can crush high-temperature materials below 150°C and can detect the bearing temperature in real time.

Application

PFL-Ⅲ (ⅢX) series vertical compound crusher is widely used in the fine crushing of various ores in metallurgy, mining, sand aggregate, cement mining, and other industries. It can crush limestone, dolomite, lime, sandstone, and medium-soft iron ore. Stone and other dry and non-stick materials below 160MPa, and it is also used for fine crushing of high-hard and brittle materials under special circumstances.
