PCL vertical axis impact crusher is a new material self-impact crusher developed by Shanghai Yuli Road & Bridge Equipment Co., Ltd. on the basis of Metso Barmac sand making machine. It uses materials to accelerate in the high-speed rotating impeller, and the crusher. The material in the vortex chamber crashes and breaks from the liner, breaking the conventional extrusion crushing principle. Since its production in 2012, the machine has nearly 100 sets of metal and non-metallic ores, cement, refractories, glass materials, building aggregates, machine-made sand, and steel slag, which are widely used in 27 provinces and municipalities across the country. Rough grinding operation. Compared with cone crusher, roller crusher, rod mill and ball mill, PCL vertical shaft impact crusher has the advantages of less investment, high efficiency and energy saving, dry production, small iron pollution and easy replacement of wearing parts.
1 .PCL vertical axis impact crusher structure composition, working principle and technical performance PCL vertical axis impact crusher consists of feed hopper distributor, vortex crushing cavity, impeller, spindle assembly, base, transmission and motor and other components.
Its working principle is that the material enters the crusher from the feed hopper, and the material is divided into two parts by the material feeder. A part of the material enters the high-speed rotating impeller in the middle of the material feeder and is rapidly accelerated in the impeller. The acceleration can be achieved. Hundreds of times the gravitational acceleration, then projected from the three equally distributed flow paths of the impeller at a speed of 60 to 75 m / s. It is first impacted with a part of material falling freely around the distributor, and then impacted to the vortex chamber. On the inner material bed, it is rebounded by the material bed, and it impacts diagonally up to the top of the vortex chamber, changes its direction of movement, and deflects downward. The material emitted from the impeller channel forms a continuous material curtain. In this way, a piece of material is subjected to two or more chances of crushing in a vortex crushing chamber. The broken material is discharged from the lower discharge port. The closed loop is formed by the circulating screening system. Generally, the material can be reduced to 20 meshes after three cycles. During the entire crushing process, the materials are impacted and broken by themselves, not in direct contact with the metal components, but instead they collide with the material lining, rub against and crush, thus avoiding the traditional impact crusher (hammer, impact crusher, etc.) ) Disadvantages of wear and tear.
During the entire crushing process. The materials are broken and impacted with each other, or impacted and rubbed with the material layer in the cavity. They are not directly contacted with the mechanical metal elements. This reduces the problems of iron contamination and steel in steel slag crushing. The ingenious air flow inside the turbulent crushing chamber is self-circulating, which can significantly reduce dust pollution. According to the size of the crusher impeller diameter, PCL vertical axis impact crusher can be divided into PCL-5545, PCL-7011, S-8, S-10 and S-12 five kinds of specifications.
2.PCL vertical axis impact crusher work features:
(1). Abrasion resistance is limited to the material. Compared with the traditional crushing grinding equipment, the self-crushing action eliminates the contact between the material and the metal parts and reduces the wear of the metal parts to a low level. With a very small amount of iron, the glass materials, ceramic materials, and special refractory materials have effectively solved the problem of iron contamination.
(2) Selective crushing The self-grinding action has the characteristics of selectivity. It can make the softer and more destructive materials broken first. It can be used to break chrome ore diamond ore, etc. It can improve the grade of harder ore, and can be used for each The crushing of metallurgical slag not only allows the effective separation of slag and metal, but also solves the problem of the equipment damage of card steel in the existing crushing equipment.
(3). The coarse grinding material is gradually accelerated in the impeller and then thrown into the ore bed in the crushing cavity at a speed of 45~90m s/, and the complex crushing process such as impact and whirl friction between the materials is combined. Together, the effect is very strong, resulting in a large amount of fines and powders, a large crushing ratio, and a coarse grinding function. It is used in artificial sand making and is superior to rod grinding.
(4). Particle shape PCL vertical impact crusher crushes the shape of the stone after the crushing. The shape of the stone is mostly cubic. As a building aggregate, it has high strength and wear resistance. Cube-shaped particles are also conducive to heap leaching.
(5). Handling Wet Material PCL vertical impact crushers are less sensitive to moisture than most other crushers. The critical moisture content of crushers used for material clogging is 7-9%. However, the machine can still effectively crush materials with less than 20% water content without clogging.
(6). Energy saving When the impeller speed is constant, the processing capacity is proportional to the installed power. When the materials are all accelerated into the impeller, the relationship between power and output is relatively clear. When the impeller linear speed is 70ms/s, the unit mass power consumption is 1.4. ~ 1.7kwh/t, it is more complicated for the overflow feeding method. With the different ratio of overflow feeding material and feeding material to the impeller, the overflow feeding does not increase the power consumption, and the increase in output per kilowatt of electricity is different. , that is, the power consumption per unit of production is reduced.
(7). The speed of crushing the hard material and abrasive material impeller is one of the factors that determine the crushing ratio. The higher the rotation speed, the greater the impact energy value and the finer the product particle size. For the crushing of special hard, medium hard and abrasive materials, it is more advantageous than the traditional crusher. Due to the characteristics of the minerals being broken, it is not necessary to consider the strength, hardness and abrasiveness of the contact ore metal parts as the traditional crusher. As long as the speed of the impeller is increased, crushing of special hard, medium hard and abrasive materials can be achieved, which greatly reduces the weight of the equipment. The weight of the whole machine is less than 1/5 of the cone crusher with the same processing capacity, and 1/7 of the rod mill. , greatly saving equipment investment.
(8). Maintenance and repair Because of its simple structure, it has few wear elements and is easy to use and maintain. Replace wear-resistant body 1-2 people, 1-2h can be completed. The installation does not require special foundations and fixings. The vertical impact crusher is lighter than the crusher made of bulky castings and is particularly suitable for mobile equipment.
3. Practical application of PCL vertical shaft impact crusher
3.1 Application in Glass Ceramic Industry Taiyuan Glass Factory is a 500t/d float glass plant. The original raw material workshop uses two PYD-1200 spring cone crushers and several pairs of table-to-roller crushers. The glass raw material is quartz and long. Stone, broken by 50 mm to 28 mesh. In 2012, two PCL-7011 vertical axis impact crushers and screening equipment were purchased from our factory. A section of crushing not only met the output of 25 tons per hour, but also replaced the cone and multiple counter crusher, and eliminated iron removal. Equipment, glass quality has also improved. After visiting the Taiyuan Glass Factory of Qinhuangdao Yaohua Glass Factory, the cone crusher was replaced with two PCL-7011 vertical axis impact crushers. Liaoning Lingyuan Xiangdong Glass Factory, based on the experience of Taiyuan Glass Works and Qinhuangdao Glass Works, designed the new plant, and used four S-10 vertical impact crushers in series to replace the originally designed cones during equipment selection. Crusher and rod mill. Taiwanese joint venture Yantai K-feldspar processing plant uses PCL-7011, S-8. The vertical crusher-based crushing and screening lines are each provided, and the position of the S-10 vertical axis impact crusher is also reserved.
3.2 Application in Abrasive Industry A mineral company in Tianjin. It exports 200,000 tons of alumina-vanadium earth, accounting for 10% of the country's total exports. Because of the high Al?O? content and hardness of sintered Al-B, the use of conventional E-break and roll-to-roll breaker not only replaces the wearing parts once a week, but also has a large particle size and excessive iron content. Foreign investors clearly stated in the ordering contract that they must be processed by the vertical impact crusher manufactured by Barmac. The company originally planned to import a vertical impact crusher from Barmac, excluding customs duties, freight and commissioning fees, and about 80,000 US dollars. After selecting the PCL vertical axis impact crusher produced by our factory, only one-tenth of the import price was used. Since the company was installed and used in the first half of the year, it has exported 150,000 tons, and its product quality meets the requirements of foreign companies. It is estimated that the total annual export volume will be nearly 300,000 tons with an output value of nearly 200 million yuan.
A certain potassium feldspar processing plant in Yantai has a crushing and screening line based on PCL-7011 and S-10 vertical axis impact crushers. It can directly process 250mm long rock into powder and produce 8 to 32 mesh long feldspar powder per month. About 10,000 tons, 32 heads to 120 heads, 4500 tons, and 120 heads, 500 tons, are exported to Japan, Taiwan, and other regions.
4 Problems that should be noticed in the application of impact crushing system (1) As the principle of crushing of PCL vertical shaft impact crusher is self-shock crushing of materials and materials, therefore, the material feeding requirements are as uniform as possible, the material has a large impact chance, and the crushing effect is good. The general charge is 0.8-1 t/kwh (including closed-loop return material) for installed power. Therefore, it is very necessary to add raw material bins and feeders before impact crushing.
(2) Due to the large amount of feed material, the impact probability is broken. When the finished product is fine particles, the return amount is large, so the transport system must transport a large amount; the screening machine has a large screening capacity, and it is easy to use a multi-layer vibration sieve, otherwise the impact crusher capability is limited to be fully utilized. The impact of excellent crushing capacity for the installed motor current reaches the rated current.
(3) Since the impeller of the crusher is a high-speed rotating body, wear parts of wearing parts wear faster and should be checked frequently. Prevent excessive wearing of wearing parts.
Proved by the use of more than 100 units in the country for many years, PCL vertical axis impact crusher, due to the use of materials and materials from the impact of the crushing principle, with high yield, wearing parts of low wear, rapid replacement, product particles were cubic, and contain Less iron. For hard, medium hard materials, moisture content, mud content of materials are suitable for use. It has low noise and dust, and its price is only one-tenth of the import price. We believe that in the near future, the use of PCL vertical shaft impact crushers will be more extensive, and the economic benefits for the majority of users will be more substantial.
