Product List

Jaw crusher
It has the characteristics of large crushing ratio, uniform product particle size, simple structure, reliable work, easy maintenance, and economical operating costs.By simulating the movement of the animal's two jaws, that is, the relative movement of the moving jaw and the static jaw, the material crushing operation is completed.Jaw crushers are widely used in many sectors such as mining, smelting, building materials, roads, railways, water conservancy and chemical industry, and are used to crush various materials with a compressive strength of not more than 320 MPa.Its superior performance makes it an ideal equipment for mining resources and material crushing in various mines.

Cone crusher
It is suitable for crushing ores and rocks above medium hardness.Its main working principle is that through the rotation and swing between the moving cone and the fixed cone, the material is subjected to strong extrusion and shear forces in the crushing chamber, so as to achieve crushing.The cone crusher has the advantages of large crushing ratio, high efficiency, low energy consumption, and good particle size of the finished product.At the same time, its structural design makes the equipment more stable and reliable, easy to maintain and maintain.Cone crusher is widely used in metallurgy, construction, chemical industry, cement and other industries, and is one of the important equipment for mining resources and material crushing.

Impact crusher
It is widely used in various ore crushing, railway, highway, energy, cement, chemical industry, construction and other industries.Its large inlet and high crushing chamber are suitable for high material hardness, large block size, and less stone powder in the product. At the same time, the gap between the counterattack plate and the hammer can be easily adjusted, effectively controlling the particle size of the discharge and the particle shape is good.In addition, the impact crusher also has the characteristics of compact structure, strong rigidity of the machine, large moment of inertia of the rotor, high chromium plate hammer impact resistance, wear resistance, and high impact force. The keyless connection makes maintenance convenient, economical and reliable.

Impact sand making machine
The high-speed rotating impeller is used to accelerate the material to an extremely high speed, and then the material repeatedly shocks, collides and rubs between the impact plate and the material lining, so as to achieve the purpose of crushing and shaping.It is widely used in the crushing and shaping of various ores, cement, refractory materials, bauxite clinker, emery, glass raw materials, mechanism construction sand, stone, and various metallurgical slag.Especially for high-hardness, extra-hard and abrasion-resistant materials such as silicon carbide, emery, sintered bauxite, and mesa, the output efficiency is higher than that of other types of crushers.It plays an important role in mining, construction, roads, railways and other fields.Its working principle is based on the principle of impact crushing between materials.

Vibrating screen
It has a strong production capacity, and the vibration motor is excited as the vibration source, so that the material is thrown up on the screen and moves forward in a linear motion, so as to achieve an efficient screening process.Secondly, the operating cost of the vibrating screen is low, and its special screen design structure makes it easy to replace the screen and reduces maintenance costs.In addition, the screening accuracy of the vibrating screen is high. The screen box is welded from steel plates of different thicknesses, and the strength is relatively strong when screening materials. In addition, the screen is made of a combination of various materials, which makes the screening process more accurate and provides a strong guarantee for the efficient operation of the production line.


Mobile crusher truck, also known as mobile crusher, is a kind of efficient and flexible crushing equipment, which is widely used in building sites, mines, highway construction and other fields. The following is a detailed introduction of mobile crushing truck:
It combines a variety of gravel principles, such as crushing, splitting and breaking, to ensure that the material can meet the ideal particle size requirements during the crushing process.Its structure mainly includes primary crushers, secondary crushers, belt conveyors, etc. Crushers at all levels are separate working units and can undertake different responsibilities.At the same time, it has an integrated vibrating screen and feeder, which makes the overall structure of the equipment compact and easy to operate.In the field of construction, it can crush and reuse construction waste to reduce waste emissions; in the field of metallurgy, it can crush and screen ore, metallurgical waste residue, etc. to improve the efficiency and quality of metallurgical production; in the field of chemical industry, it can crush and mix chemical raw materials to improve production efficiency and reduce production costs.
