Vertical Shaft Impact Crusher

VSI series high efficiency vertical shaft impact crusher (sand maker) is stone crushing equipment with domestic and international advanced technologies, which combined the actual demand of China sand-making industry. It is widely applied to process all kinds of ores, concrete, fireproof material, bauxite, quartz, basalt, glass, etc. Especially for some very hard materials, VSI crusher has more advantages than other kind of machines. Vertical shaft impact crusher design and other impact equipment depends on the ore and hard object between the impact, therefore, they have the same basic characteristics with other impact crusher, its design is better than the extrusion. This kind of top feed, bottom-driven vertical shaft impact crusher is lightweight and compact, making it easy to install in existing or new workflow.

Advantages and characteristics:

1. Noveland distinctive design, simple and reasonable structure, smooth operation and low operating
2. Lowenergy consuming, high yield, large breaking proportion and energy
3. Theequipment is capable of shaping out  Products take a cubic shape and enjoy high bulk density.
4. Duringthe manufacturing, stone materials can form a protective bottom to avoid wearing the equipment, so the equipment is wear well.
5. Fewwear parts are made of wearing resistant material of special hardness, which is small in volume, low weigh and easy to be
6. Automaticair circulatory system can purify concentrative screening
7. Watercontent of the material exerts little influence, the maximum contenting water can be around 8%.
8. Alubrication oil station is adopted to lubricate the mayor bearing in circulation to ensure a constant oil

Working Principle:

Vertical Shaft Impact Crusher works as below: The materials enter the crusher through feeder hopper, which is divided into two parts, one part entering into the rotating through the middle of distributor impeller at high speed, then is accelerated, and shot through the tunnels around the impeller by the speed of 60-75 meter/second.

First the materials will impact with some materials fallen around distributor, hit on the crushing chamber together, then will be rebounded and impact on the top of the crushing chamber, changes its direction and goes down, forms continual material layers with the materials shot from the impeller.

Therefore some materials will be impacted, crushed, milled twice or more times in the crushing chamber, then crushed materials will be discharged through the bottom. This can form a closed circulation system;

In general, the sand forming percentage increases 20-30% and the product shape is good. Airflow self-circulation in the crushing chamber can eliminate the dust pollution well. It is the first choice in manufacturing sand and its shape correction industries.

Feature:

1. Advanced double pump oil lubrication system minimize the maintenance frequency
2. High precision roller bearing, smooth main unit running, and long service time
3. Hydraulic lift cap, easy and convenient replacement and maintenance
4. Over vibration alarm system
5. Special dustproof seal system, outside powder is prevented from entering oil mouth
6. Unique feeding method (change between central feeding and central feeding with cascade feeding make “rock on rock” and ‘rock on iron”possible, both crushing and shaping are achieved.
7. Particular material throw head design and reasonable material selection prolong the service time.
