Compound Crusher

What is Compound Crusher?

A compound crusher, also called vertical compound sand maker, is a double-rotor primary impact crusher. The compound crusher is an ideal machine for crushing high-moisture and viscous materials, commonly used in small-scale crushing and sand production lines.

Compound Crusher Advantages

Compound crusher combines the advantages of impact crusher and hammer crusher, showing multiple highlights. Its features include:

1.This model has both primary and secondary crushing functions, which not only has high crushing efficiency but also has lower cost.
2.With large crushing ratio, it can refine the material of 100-240mm to small particles below 3-5mm at one time.
3.The gap between hammer head and impact plate can be flexibly adjusted to meet different particle size requirements.
4.Designed with gridless structure, so it is not easy to be clogged even when dealing with materials containing a large amount of slurry.
5.Long bearing life and horizontal arrangement enables it to handle high temperature materials such as cement clinker.
6.Low noise level of 75 decibels (dB) during operation and effective control of dust pollution.
7.The wearing parts are made of special alloy material, which combines high hardness, high toughness and multi-element alloy wear resistance, significantly extending the service life to 2-3 times of the original.
8.The rear chamber is equipped with a screw or hydraulic pressure opener, which greatly facilitates the replacement of wearing parts.

The vertical compound crusher is mainly composed of the crushing system (rotor, bearing, liner, hammer), transmission system (motor, pulley), in-and-out mouths, and other parts. Among them, the crushing system is the easy-wearing component, which is mainly introduced for you.

The flat hammer is a vulnerable part of the crusher, installed on the rotor. They break the material by striking it repeatedly.

The hammer head is made of wear-resistant alloy steel or bimetal thermal compound material and the weight is generally between 9-36 kg.

The rotor is a key part installed vertically in the crusher and is made of solid cast steel. The rotor circumference is equipped with hammers with adjustable clearance, responsible for high-speed rotation.

The rotor has a special structure that won’t be worn once crushed. The speed and rotation direction of the rotor affect the crushing efficiency.

The liner plate refers to the wear-resistant plate inside the crushing chamber, which plays the role of grinding materials and protecting the cylinder from wear.

The special casting and heat treatment process makes the liner have good impact resistance.

The bearing assembly supports the rotation of the rotor and is critical to the smooth operation of the crusher.

Generally, double-row radial spherical roller bearings are selected, which have strong bearing capacity and good self-aligning performance.

Compound Crusher Application

Compound Crusher has a wide range of applications and is commonly used for crushing medium-hard materials in middle or small-sized plants. Here are some specific applications:

Coal, limestone, granite, cobble, dolomite, bluestone, iron ore, coal gangue, activated carbon, quartz, basalt, slag, etc.

Application of Compound Crusher

The Working Principle of Compound Crusher

The material in the upper part of the machine perpendicular drops into the high speed rotating impeller,and under the high speed centrifugal force, it produces high speed impact and comminution with the other part of the material which distributes in the shape of umbrella around the impeller vertical composite crusher. The impeller and the housing will be crushed by swirl impact and friction between the impeller and the housing for many times, which will be discharged directly from the bottom, forming a closed circuit multiple cycles, and controlled by the screening equipment to achieve the required product size.
