It is widely used in industrial sectors such as metallurgy, mining, cement, chemicals, refractory materials and ceramics,
as well as in highway construction, water conservancy projects, construction gravel, machine-made sand processing and other fields.
It is suitable for medium and fine crushing of various soft and medium-hard ores, such as: limestone, feldspar, calcite, talc, barite, fluorite, rare earth, kaolin, coke, gangue, gypsum, etc.
When the impact crusher is working, driven by the motor, the rotor rotates at high speed.
When the material enters the blow bar action area, it collides with the blow bar on the rotor and is broken.
Then it is thrown to the counterattack device for crushing again, and then passes through the counterattack lining.
The plate bounces back to the plate hammer action area for re-crushing. This process is repeated. The materials from large to small enter the first,
second and third impact chambers for repeated crushing until the materials are crushed to the required particle size and discharged from the discharge port.
Adjusting the gap between the impact frame and the rotor can change the material discharge particle size and material shape.
The high-efficiency fine crusher is a kind of continuous production crushing equipment with the characteristics of stable operation, adjustable discharge, and easy maintenance.
It is suitable for fine crushing and artificial sand making applications of granite, basalt, limestone, river pebbles, cement clinker, quartz stone, iron ore, bauxite and other materials.
It is used in roads, construction, cement, metallurgy, refractory and other industries. Provide sand and gravel aggregate.
When the high-efficiency fine crusher works, driven by the motor, the rotor rotates at high speed.
The material enters the first crushing chamber for crushing and is crushed by impact with the plate hammer on the rotor.
Then it enters the second fine crushing chamber for crushing, and then is discharged from the discharge port.
The difference between impact crusher and high-efficiency fine crusher:
1. Internal structure
Although both rely on the rotation of the rotor and impact of materials to achieve the purpose of crushing,
it is obvious that the square hammer head is installed on the rotor of the fine crusher, while the blower is installed on the rotor of the impact crusher, and the fine crusher has more crushing tools than the impact crusher.
If the grate strips are removed, the fine crusher can also be used as an impact crusher.
2. Feed particle size and discharge particle size
The feed particle size of the fine crusher is controlled within 200mm, while that of the impact crusher is controlled within 700mm.
The discharge particle size of the fine crusher is controlled within 0-10mm and is adjustable, while the impact crusher does not indicate this clearly, indicating that the adjustable range is wider.
That is to say, the tertiary crusher is mostly used in the three stages of crushing (that is, sand making) after fine crushing, while the impact crusher is used in the medium and fine crushing stages to break into stones.
3. Range of materials processed
As we all know, the impact crusher can handle materials with a hardness that generally cannot exceed 350MPa, and is not suitable for processing materials with relatively high hardness such as river pebbles,
basalt, iron ore, etc., while high-efficiency fine crushers can handle hard, hard materials such as cement clinker and limestone. The fine crushing of brittle materials has a wider range of material processing.
4. Purpose
By analyzing the particle size of the inlet and outlet of the two types of equipment, it can be roughly summarized as follows: the high-efficiency fine crusher acts in the sand production line, while the impact crusher acts in the gravel production line.
If the impact crusher is used to make sand, problems may occur. More powder.
