Which crusher has a capacity of 400t/h for stones? Capacity of 400 t/h is relatively high for stone crushing and ordinary stone crushers can not complete it. However, equipment configuration for stone crushing can be one production line or multiple production lines. Now I’d introduce the equipment configurations for different stone requirements.
What factors need to be considered in equipment configuration for stone crushing? Every stone production has requirements basically on capacity, next on finished product size and our only goal is to increase capacity under condition of meeting requirement on finished product size.
Generally, client’s requirements are these basic ones but there are various stones including coarse aggregate, fine aggregate, sand&stone, fine sand, etc. which need different equipment to process; for example, aggregate processing needs impact crusher and cone crusher while sand&stone processing and fine sand processing need special sand-making machines like VSI sand-making machine, fine crusher, etc. Now let’s see which crushing equipment is more suitable through comparing the following two examples.
1.Fished product requirement: 25mm required material: aggregate capacity: 400t/h equipment configuration solution:
Impact crusher or other hammer structure crushing equipment for soft materials and specific solution is as followed:
Solution 1: to select a 2015 model heavy-duty hammer to complete the capacity of 400t/h; its discharging size is 0-80mm, capacity is 400-500t/h; it has few requirements for raw material size, has high crushing ratio, needs few equipments and is easy to be operated, which is applicable for medium and small stone processing plants.
Solution 2: two sets PF-1315 impact crushers and two sets of PE750x1060 jaw crushers. These two kinds crushers work cooperatively with jaw crusher used for first stage crushing and impact crusher for second stage crushing, forming two stone production lines. It’s common that several production lines work together to complete required capacity. Besides, impact crusher also called as universal crusher is popular among stone crushing process.
If the raw material is hard, like pebbles, hammer crusher is not suitable anymore because hammers are worn heavily by hard materials, which will increase production cost. While cone crusher is usually selected because it is effective to crush hard materials and its finished products have good specification.
Solution 3: two sets PYZ1750 cone crushers and two sets PE750x1060 jaw crushers. This solution is similar to solution 2. And its corollary equipment contains vibrating feeder, vibrating screen and belt conveyor, etc.
2.Fished product requirement: 5mm required material: fine sand capacity: 400t/h
The crushing principle and equipment selection principle of sand making is same with that of stone crushing, except the finished products get smaller. Common sand-making machines are high-efficiency fine crusher, PCL sand-making machine, VSI sand-making machine, etc. And the specific equipment configuration solutions are as followed:
Solution 1: two sets 1600X1600 fine crushers, discharging size:<5mm, capacity for hard materials: 170-210t/h, capacity for soft materials: 190-250t/h, together with corresponding model jaw crusher and impact crusher as first stage crushing and second stage crushing.
Solution 2: two sets VSI-8515 sand-making machine or one VSI-1140 sand-making machine. VSI is a new sand-making machine with wide material application and high specification which is a customized equipment in road and bridge projects and has huge development potential.
Capacity of 400t/h is common in stone production industry and it is skillful to select equipment. The precondition is the capacity requirement and the key is to determine material’s hardness, humidity and know the finished product requirement. And there are many selections to satisfy cost requirement but it’s worth to be clear about what selection is economic to users. Zhengzhou General Mining Machinery Co., Ltd. can prepare several equipment selections and analyze the advantages and disadvantages of every selection for clients and recommend a proper selection according to client’s actual conditions.
