The newly-developed VSI (vertical shaft impact) crusher is a crusher and shaper. Changing feeding methods and core structure of the crushing cavity, it can be used as a crusher or a shaper. Thus, customers do not need to expand investment, they have a crusher and a shaper at a time.
SBM Vertical Shaft Impact Crusher is the most advanced impact crusher in modern world. It introduces high quality roller bearing like Sweden SKF and America TIMKEN, which ensure the smooth running of main unit. Hydraulic system used in upper cap, it is easy and convenient to maintenance and replace spare parts. The feeding is our sole patent that using central feeding and central feeding with cascade feeding, the feeding method can change as per needed so as to satisfy customer’s different request.
Vertical Shaft Impact Crusher Application
VSI sand making machine used in building construction, road construction, coat, and asphalt concrete, water resource and hydropower, bridge, airfield runway and so on. VSI sand making machine can crush Pebble, River stone, Mountain stone (limestone, granite, basalt, diabase, andesite) mine tailings, stone chips, non-metal ores, cement, bauxita, silicon carbide, etc.
Vertical Shaft Impact Crusher Features
1. High output and wide utilization ratio: compared with traditional machinery under same power, its production capacity increases 30% and structure is stability.
2. Low consumption of easy-wear parts.
3. Excellent shaped final products.
4. Lubrication system ensures reliable operation.
5. Over-vibration device is equipped to protect the machine when vibration surpasses a stipulated figure.
6. The adjustable feed hopper guarantees the best quantity of material.
7. Environment friendly.
Vertical Shaft Impact Crusher Working Principle
Working pinciple is as follows: the materials enter the crusher through feeder hopper, is divided into two parts. One part goes through the middle of classifier entering into the rotating impeller at high speed, then accelerated, whose speed can reach hundreds of acceleration. Under great centrifugal force,it is 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 classifier, then impact on the whirlpool cavity's scaleboard together, then will be rebounded and impact on the top of the whirlpool cavity, then changs its direction and goes down, forms continual material layers with the materials shot from the impeller.
Therefore some materials will be impacted, crusher, milled twice or more times in the whirlpool cavity, then crushed matetials will be excluded through the bottom discharging hole. This can from a closed circulation through the circular classifier system. Finally smaller stone comes out, and goes to vibrating screen. Satisfactory material is transported to sand washing machine; however overlarge material will go back to sand maker to be refreshed. Output sizes can be made according to customers’ requirement. If input size is larger than the designed size, other crushing equipment will be necessary. in general, materials can be crushed into 20 mesh through thrice circulation. Airflow self-circulation in the whirlpool cavity can eliminate the dust pollution well.
