Unlike other crushers, impact crushers use impact instead of compression to crush materials.Equally effective in primary and secondary crushing, high speed rotors with wear-resistant hammers impact the material before throwing it against anvils in the crushing chamber to break it down.Openings on the bottom or side then allow for the crushed material to escape.
Impact sand gravel making machine instructionvsi impact crusher is new type sand making the machine, has better comprehensive performance than the rod mill sand making machine, the straight-through impact sand making machine, and the cone crusher and soft hammer crusher.It has the characteristics of stable and reliable work, convenient maintenance and high sand production rate.The equipment is suitable for stone shaping, production mechanism sand, sand making field, high-grade highway, railway, water conservancy, construction, cement, refractory, metallurgy, glass sand, and other industries.Structurevsi sand making machine features1.Special light oil lubrication system ensures the temperature to be within 25 c.2.Brand new automatic protection device provides the machine with vibrating, oil filtering and warning system.3.A new type oil filtering device ensures the bearings and other transmission devices not being abraded and prolong their service time.4.Optimized design of wearable materials has prolonged the service time of the machine by 40%, so the cost is lowered by more than 40%.5.Better design of the impellers reduces the resistance of materials; high lightens passing through quantity of materials and crushing ratio, so the efficiency is raised by 30%-60% compared to traditional machines.6.The hydraulic system allows automatic uncovering, which reduces labor intense and makes maintenance easier.7.The mainframe adopts new techniques, which strengthens the machine structure and tenacity, and ensures stable performance.The quality of the machines is to lift to a higher level.Technical parametersmodelfeed at center&sidesfeed at centersoft materialhard materialrev (r/min)power (kw)motor modelmachine size (mm)capacity(t/h)max.Feeding(mm)vsi7611120-18060-9035301700-18904-552y250m-4/55410022502258vsi8518200-260100-13040351520-16904-902y280m-4/90414022802425vsi9526300-380150-19045401360-15104-1322y315m-4/132456024502780vsi1140450-520225-26050451180-13104-2002y315l2-4/200456024502780.
As the specialist mining machinery manufacturing company, henan hongxing mining machinery co., ltd, it has almost 30 years' development and dedicates itself to mining crushing equipment, grinding equipment and ore selecting equipment.Many years, with the technology of perfection with more perfection and after-sales' service of perfection, hongxing machinery wins a great high benefit year by year.As the high quality of mining machinery equipment manufacturing company, we will create benefit for customers with first-rate technology, equipment and service to cooperate and create the national famous brand.As a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete stone crushing station.We also supply individual impact crusher and vibrating screen as well as spare parts of them.
Impact crushers involve the use of high speed impact rather than compression to crush material.They utilize hinged or fixed heavy metal hammers or bars attached to the edges of horizontal rotating disks.The bars repeatedly strike the material to be crushed.Then the material is thrown against a rugged solid surface which further degrades the particle size.Finally, the material is forced over a discharge grate or screen by the hammers through which the finer particles drop while larger particles are swept around for another crushing cycle until they are fine enough to fall through a discharge grid.this type of crusher is normally used on soft materials such as coal or limestone due to the high wear experienced by the impact hammers, bars and inner surfaces.these crushers are normally employed for secondary or tertiary crushing.
Taking the 'innovation' as the source for enterprise development, since its inception we attached great importance to the construction of r & d team.Our company continues to explore in the mining machinery industry, and gained three more authorized patent product certifications in impact crusher in 2011 from the state intellectual property office.All the members adhere to "energy-saving innovation" in order to create the 'made in hongxing' brand with practical action.
The latter impact crusher made of world-class manufacturing processes.It not only ensures the quality of the rotor parts, but also makes the machine runs more reliable.The hydraulic control system can be quickly adjusts outlet size and grain size.Its automatic hydraulic open device can quickly complete the plate hammer, the replacement of wearing parts, reduce downtime and maintenance time.In the coarse crushing operations, two crushing chamber can simplify the process; in the fine operation in the crushing chamber, three showed extraordinary.Two kinds of cavity can meet the requirements of the vast majority of coarse and fine crushing.
