At present, there are three kinds of crushing equipment (sand making machine) that can be used as the third stage of fine crushing and sand making in the sand and gravel production line: vertical impact crusher, vertical shaft impact crusher and vertical complex crusher. These three crushers are all equipment for crushing materials in the form of impact. The most widely used is the vertical impact crusher, which is used to finely crush and reshape coarse sand in the aggregate processing industry to optimize the adjustment of the sand rate the role of grading. "Existence is reasonable", each type of crushing equipment has its own unique performance advantages and applicable aspects, and composite crushers are no exception. Today, let's talk about the performance characteristics and applicable materials of the complex crusher.
PFL series vertical complex crusher is a new type of fine crushing and coarse grinding product that our company integrates similar domestic and foreign crusher technology and combines with the company's many years of practical experience to optimize the design and development. This product has both impact and grinding crushing mechanisms. The composite crusher can achieve more crushing and less grinding, is an ideal fine crushing equipment for energy saving and consumption reduction, widely used in the crushing operation of raw cement and clinker, and also widely used in metallurgy, mining, sand and aggregate, cement mining and other industries The fine crushing operation of various kinds of ores can crush various dry and non-sticky materials under 160MPa such as limestone, dolomite, lime, sandstone, medium soft iron ore, etc. It is also used for fine crushing of high-hardness and brittle materials under special circumstances.
The PFL series vertical complex crusher is designed according to the principle that the input energy of the materials is increased step by step and graded. After the material falls into the crushing cavity, it is first thrown out through the material throwing tray at high speed and hits the impact plate to form a primary crushing. Then fall into the gap between the hammer head and the counter plate, the gap gradually decreases from top to bottom. The material is crushed by hammering, squeezing, grinding, etc., gradually from large to small, and finally reaches the set particle size, discharged from the crusher, forming a closed circuit multiple cycles, and controlled by the screening equipment to achieve the required particle size.
1. The crushing ratio is large, the maximum feeding particle size is 80 ~ 240mm, and the discharging particle size ≤ 3mm accounts for about 90%.
2. The output is high, and the crushing process is straight-through crushing. Due to the large throughput of the material and the fast passing speed, the output is high. Relatively speaking, energy consumption is less. This machine is used in conjunction with the mill to increase the output of the mill by about 40% and the power consumption of the system by about 30%.
3. The wearing parts are made of high-hardness, high-toughness multi-element alloy wear-resistant materials, with less wear and long life. The distance between the hammer head and the impact plate can be fine-tuned to ensure uniform product size, the utilization rate of the hammer head is greatly improved, and the service life is increased by about 5 times.
4. Environmental protection and energy saving the new composite stone crusher can spray water and reduce dust during the production process to reduce the pollution to the environment, and it is more environmentally friendly.
5. The unique material-throwing disc structure is composed of material-throwing ribs and material-throwing lining plates distributed in a circle. After the material-throwing ribs are worn, they can be used as material-throwing linings, which greatly improve the material utilization rate and reduce the use cost.
6. The application of cooling system and bearing temperature detection device can crush high temperature materials below 150°C and can detect bearing temperature in real time.
7. The structure is compact and the design is reasonable. During the installation process, the operation is simple, and the later maintenance is more time-saving and labor-saving.
PFL series vertical composite crusher can crush high-temperature materials below 150℃, with optional water-cooled chassis, high-temperature bearing, high-temperature grease resistant to high temperature above 260℃, widely used for crushing raw cement and clinker, widely used It is used for fine crushing in metallurgy, sand aggregate, cement mining industry, and can crush limestone, dolomite, lime, sandstone, iron ore and other dry and non-stick materials below 160Mpa.
