矿山设备指南：What Equipment Should You Use for Primary Crushing and Construction Waste Processing? A Complete Guide to 6CX Euro Series Jaw Crushers and C Series Counterattack Crushers

The 6CX series jaw crusher adopts the most advanced crushing technology and research results internationally. Based on decades of experience in jaw crusher design and manufacturing, and utilizing finite element analysis, it has successfully developed a new generation product with world-leading standards. Compared with traditional jaw crushers, the 6CX series pays more attention to design and manufacturing details, using high-strength materials and advanced manufacturing processes, offering advantages such as higher structural strength, greater equipment reliability, larger crushing ratio, higher output, and lower overall processing costs. The C series impact crusher can achieve both coarse and medium-fine crushing, functioning as a dual-purpose machine. It is suitable for all kinds of materials with a compressive strength not exceeding 350 MPa (such as granite, limestone, concrete, etc.) for coarse, medium, and fine crushing, and is widely used in mining, construction, chemical, power, and metallurgical industries. This series of equipment can switch between coarse and medium-fine crushing by adjusting the installation position of the impact frame, making it a dual-purpose machine with a larger feed opening. During coarse crushing, it can be used as a primary crusher with a maximum feed size of up to 1000 mm. When crushing construction waste, it effectively prevents rebar entanglement. Why choose these two pieces of equipment? First, the 6CX European version jaw crusher has advanced technology, optimized design through finite element analysis, and is made of high-strength materials, giving it higher reliability, greater crushing ratio, higher output, and lower overall processing costs. Second, the C series impact crusher is dual-purpose and can switch between coarse and medium-fine crushing by adjusting the impact frame position, reducing equipment investment. Third, the C series has a large feed opening, with a maximum feed size of up to 1000 mm for coarse crushing, suitable for large materials. Fourth, the C series prevents rebar entanglement, making it effective for crushing construction waste and ideal for urban construction garbage handling. Fifth, it is widely applicable to mining, construction, chemical, power, and metallurgical industries and can handle materials such as granite, limestone, and concrete with a compressive strength not exceeding 350 MPa. These two pieces of equipment are mainly used for coarse and medium-fine crushing in mining, construction waste processing and crushing, material crushing in construction, chemical, power, and metallurgical industries, coarse and medium-fine crushing in sand and gravel aggregate production lines, and stone processing for road and bridge construction, and water conservancy projects. The groups of people who need these two types of equipment include mining companies, construction waste processing companies, sand and gravel plants and aggregate producers, road and bridge engineering construction units, equipment procurement departments of chemical, electric power, and metallurgy enterprises, EPC contractors for crushing and screening production lines, equipment dealers and inventory holders, and overseas mining and building materials project buyers. Under what circumstances should these two devices be chosen or replaced? When a mining coarse crushing requires equipment with a high crushing ratio, high reliability, and large output, the 6CX European jaw crusher is preferred; when construction waste processing needs equipment that prevents rebar tangling, has dual functionality, and a large feed opening, the C series impact crusher is preferred; when old equipment is severely worn, has insufficient handling capacity, or cannot meet finished product particle size requirements, it needs to be replaced; for new production lines, jaw crushers or impact crushers should be configured according to material hardness, feed size, and product requirements. How to choose these two types of equipment? Step 1: Confirm material compressive strength. The 6CX European jaw crusher is suitable for materials of various hardness, and the C series impact crusher is suitable for materials with a compressive strength not exceeding 350MPa; Step 2: Confirm the crushing stage.

Note: The 6CX EU version jaw crusher is suitable for materials of various hardness, mainly for coarse and medium crushing; the C series impact crusher is suitable for materials with a compressive strength of no more than 350MPa, capable of converting between coarse and medium-fine crushing, and can effectively prevent rebar entanglement when crushing construction waste. The maximum feed size and discharge port adjustment need to be determined according to specific models and working conditions. Explosion-prone environments require optional explosion-proof motors. For highly abrasive materials, high-chrome alloy hammers or jaw plates are recommended.

Selection considerations (Differences and comparison between 6CX jaw crusher and C series impact crusher): The core difference between the 6CX EU version jaw crusher and the C series impact crusher lies incrushing principle, applicable material hardness, and crushing stage. The 6CX EU jaw crusher uses the extrusion crushing principle, suitable for materials of various hardness (including high-hardness granite, etc.), mainly for coarse and medium crushing, large feed size, high crushing ratio, high equipment reliability, and low comprehensive processing cost, but the finished product shape is mostly needle-like or flake-like. The C series impact crusher uses the impact crushing principle, capable of converting between coarse and medium-fine crushing, serving both functions with one machine, suitable for materials with a compressive strength of no more than 350MPa. It has a large feed opening, with maximum feed size up to 1000mm for coarse crushing, good product shape, reasonable gradation, and effectively prevents rebar entanglement when crushing construction waste. However, the hammer wears quickly and is not suitable for ultra-hard materials. When selecting, for coarse crushing of high-hardness materials, the 6CX EU jaw crusher is preferred; for medium-fine crushing of soft or medium-hard materials with high shape requirements, or when handling construction waste (preventing rebar entanglement), the C series impact crusher is preferred.
