Impact Crushers

Strong Crushing Power And Adjustable Particle Size

Our impact crushers multi-stage crushing chamber has a large space and strong adaptability. It can crush hard, soft, brittle and tough materials with high water content. It is widely used in the fields of highway construction, water conservancy projects, construction gravel, machine-made sand processing, construction waste treatment and mineral processing plants. JXSC impact crushers can meet the crushing of different material specifications, and its powerful crushing power is fully suitable for the processing of hard rock.

Brief Intro

The impact crusher can complete the medium and fine crushing operations at one time, which greatly simplifies the crushing process. Such as crushed limestone, calcite, talc, barite, rare earth, clay, kaolin, dolomite, kaolin, gypsum, graphite and other aggregates or ores. In the stone production line, it is mainly used for fine crushing operations, and the crushed finished products are in the form of cubic particles. For road projects with high requirements for finished sand and gravel materials, impact crushers are usually used as fine crushing and shaping equipment. Our impact crusher can flexibly adjust the output particle size in various ways and the particle size is uniform.

Why Choose Our Impact Crushers

Impact crushers

Unique Structure


The blow bar is firmly fixed on the rotor with a mechanical clamping structure, and has a large moment of inertia when it rotates with the rotor. The crushing power is sufficient and the energy consumption is low.


Wear-resistant Blow Bar


A high-chromium blow bar with high wear resistance and toughness completely solves the problem of breaking hard materials.


Efficient Feeding


The low and large feeding port is convenient for the layout of the production line and increasing the feeding size.


Multifunction Device


The impact crusher is equipped with a multi-functional hydraulic station, which has multiple functions such as hydraulic high-speed discharge gap, stable impact plate vibration reduction, and automatic opening of the machine body.



1. Large feed port, suitable for high-hardness materials, widely used in sand making plants and mineral processing plants.

2. The gap between the counterattack plate and the hammer head can be easily adjusted by adjusting the bolt, and the discharge granularity can be effectively controlled.

3. The high-speed impact crushes the material, the content of needle flake particles is low, and the finished product has a good grain shape.

4. The multi-stage crushing cavity has a large space, overload protection device, multiple crushing ores, and various specifications.

5. High-quality blow bar and unique counter-attack liner are impact-resistant, wear-resistant and powerful; especially suitable for crushing hard rock materials.

7. High chrome blow bar and unique counter-attack liner are impact-resistant, wear-resistant and powerful; especially suitable for crushing hard rock materials.

6. The crushing ratio can reach up to 40, so the crushing process can be simplified, and the three-stage crushing can be changed into two-stage or one-stage crushing, which reduces the equipment cost of the concentrator.

7. It has the functions of three-stage crushing and shaping, so the crushing ratio is large, and the product shape is cubic, which meets the requirements of various building materials.

8. The wear and tear of the vulnerable parts of our counterattack is extremely small, and the maintenance cost is low.

9. The feed chute and impact plate of the impact crusher can be equipped with a heating device, which is more effective for processing materials with a large amount of moisture and can effectively prevent material clogging.

Impact Crushers Working Principle

When the machine works, the motor drives the rotor to rotate at high speed through the V-belt. When the material enters the blow bar action area, the high-speed impact will collide with the blow bar on the rotor and break. The back plate of the rotor can withstand the extremely high moment of inertia of the rotor and the impact and crushing force of the hammer head. After that, the material is thrown to the impact device for re-crushing, and then bounces back from the impact liner to the blow bar area for re-crushing. This process is repeated until the material is crushed to the required size. Materials from large to small enter the first, second and third impact chambers for repeated crushing. When the crushed ore particle size is smaller than the gap between the hammer head and the impact plate, it will be discharged from the discharge port.

Frequently Asked Questions

According to those aspects: material hardness, feeding size, output size needed.

12 Months for machine main parts, not include spare parts.

20-40 days depends on model, normally 30 days.

The feeding size depends on capacity, the bigger capacity with bigger feeding size. The output size can be adjusted according to customer’s requirement.

Can through two ways:

(1) Adjust the speed of the rotor, the faster the rotor moves, the smaller output will come;

(2) Adjust the gap between the impact plate and the blow bar.

Blow bar, impact plate, side plate, bearing etc.

(1) Pay attention to the balance of the rotor;

(2) Lubricate in time;

(3) Timely replacement of worn wearing parts.

(1) The feeding material is too large, you can adjust the feeding size;

(2) Uneven wear, counterattack hammer needs to be replaced;

(3) The rotor is unbalanced and needs to be adjusted;

(4) The foundation is not handled properly, and the fastening of the anchor bolts needs to be checked.

(1) The blow bar is worn, turned around or replaced.

(2) If the distance between the blow bar and the impact plate is too large, it can be adjusted appropriately. Generally, it should be adjusted to 15mm-20mm.

(3) Excessive feed particle size will also affect the output particle size.

(1) The bearing is short of oil or too much oil, check the oil level when adding oil.

(2) The bearing is damaged and the bearing needs to be replaced in time.

(3)  If the upper cover is too tight, adjust the bolts properly, and the tightness is appropriate.
