Shaft Impact Crusher

There is two franges from verticals symmetry on both end of the shaft impact crusher,the high speed revolution roller is drived by the multiple groove pulley. Materials enter into the hopper,through the center feeder into the high speed impeller ,and speedup at more than ten times of the gravitational acceleration, then discharged from the discharging opening. Firstly, they bump with other materials which fall free after being bounced back. Then they impact together on the liner plates, and bounce back to the top area of vortex chamber.Again, the materials turn their moving direction , and this time move downward, thus to form a continual material layer by striking with the materials launched from the impeller channel. In this way, big materials are impacted, rubbed and crushed two and even more times inside the vortex chamber, finally discharging in smaller size at the bottom.

Applicability

Shaft impact crusher is widely used in medium and fine crushing of special materials with high hardness and ultra hardness, such as all kinds of mining stone, concrete, fireproof material, bauxite, emery, glass raw materials,ect. It is widely used in the field of hydropower, highway,construction, concrete and metal mining.The final product is in the shape of cubic, with low content of elongated flaky particle. It is more widely used in crushing machine-made construction sand, stones and all kinds of metallurgical slags. Compared with other crushing machines, it is characterized by higher capacity, stable operation, easy maintenance and high sand-making rate.

Structure features

1.Simple structure, reasonable and low operation cost
2." Stone strikes stone" and " stone stricks iron" , a tractor serves several purposes 3.High crushing rate, energy-saving
4.Function with fine crushing and coarse grinding
5.Unaffected by moisture of material, suitable for both dry and wet materials
6.Low operation noises, less dust pollution, meeting national requirement of environmental protection
7.Suitable for crushing materials with medium, high and ultra hardness
8.Good cubic shape with final product, big bulk density, minimal iron pollution
9.Little abration of impeller, easy maintenance.

VSI Vertical Shaft Impact Crusher

VSI vertical shaft impact crusher has introduced New Zealand's advanced technology, combined with the standard of sand making industry inChina. It is currently stand a leading position inChinaand is the fourth generation of energy saving and efficient sand equipment. It is mainly applied in high railways, highways, hydroelectric dams, concrete mixing station, refractories, metallurgy and building materials industries.It is an ideal equipment for manual sand making and gravel shaping.

Working principle

Firstly,The materials falled into the turn plate in high speed, meet the target rock which is flowing around the turn plate, Then is high speed impacting and high density crushing between the turn plate and the frame,The final production will be on requirement,through so many times pressing,grinding and impacting.

Features and benefites

1. Easy reasonable and special structure,balance and low operating cost. 
2. " stone at stone" and " stone blacksmish" required adjusting the equipment,crushing sand and stone, a tractor serves several purposes
3. Low energy consumption,high production,crushing rate,saving energy and environmental. 
4. The final production shape is cubic,big pile density. 
5. During the running process,stone forms a protecting layer,the frame wears well. 
6. The quick wear part has be made of head hard materials,with small srtucture ,and easy to replace the fittings. 
7. It has the air circulation systom,reduce dust. 
8. low effect on the material moisture,it will be 8%.
9. The main shaft keeps circulation lubrication,and ensures the main frame can be feed with the oil pump. 
10. Adopt automation and alarm. 
11. The top head with a hydraulic systom, Easy operate.

Shaper

The GVZ serirs stone shaper is the fifth generation vertical impact crusher Shanghai Golden machinery CO.,LTD,which used Barmac principle.It is a production of high performance concrete (C40 and above) aggregate (stone) and necessary equipment of high quality stone.After the bone through the shaping machine (stone )metarials no more than 5% of needle flake,can fully meet the high rise building with high performance concrete(C40-C80) the technical requiements for aggregate used for highway,raiway,hydropower stations,bridges,tunnels and contrete mixing station.

Working principle

Center feeding:Material falling into the hopper,the feed from the center hole into the high speed rotation of the impeller through the impeller rapid injection hole,first with the free fall after the rebound in the other part of the materials to impact,and then with the impact of the impeller.injection material is a real stone at stone theory,a collision plastic material,so that the type of materials eventually become the best body.the last by the host body of the following discharge port discharge. 

compared with the fourth generation machines and other crusher,it has features as following

1.Excellent stone shaping capabilities,whether basalt,diabase,or limestone,tuff-pin sheet can reach than 5% level,PF impact crusher is not matched,it is the best shaping equipment in international and domestic.
2.Good particle size,reduced the production of power,also increased the service life of the wearing parts,and reduced the operated costs.
3.Advanced the impeller disigns reduced the metarials throughput resistance ,Increased the crushing ratio and the efficiency than the old machine by 10%-60%.
4.Adjustable the metarials waterfall,eradication weeks of wear protection plates.
5.Implementation of a variety of interchangeable wear parts,reducsed the wearable parts costs by 60%.
6.Improved the basis of feed grain,the maximum into 60-90mm..
