European Impact Crusher

Overview

By absorbing the most advanced technology in the world, PFW series European Type Impact Crusher produced by kefid is the latest generation of impact crusher with first-class standard. Since the rotor is the most critical part for impact crusher, Liming devotes to develop and produce the well-structured heavy rotor for larger rotary inertia. Also, the adoption of high abrasion-resistant material and well-designed crushing cavity enables the PFW series impact crusher to perform steadily and outstandingly.

The adjusting devices of PFW series has been highly improved, thus operation of it would be easy and convenient. The design of three crushing chambers make the PFW series impact crusher perform well in the fine crushing and superfine crushing operation.

The design of the two crushing chambers simplifies the flow chart of coarse crushing operation.

FOUR OPENINGS IMPELLER, SEALING STRUCTURE

Based on more than 30 years of experiences, VSI6X Series Vertical Shaft Impact Crusher carrying many patents amazes the market greatly. This machine is possess of four openings impeller, special sealing structure and sealed cartridge bearing structure, which makes production convenient and efficient.
Applications: metallic and non-metallic ore, building material, artificial sand making and every kind of metallurgical slag

LEARN MORE

New design, efficient crushing

Impeller structure adopts the design of four openings to improve the material throughput. Compared to the three opening impeller, the crushing efficiency is improved by 20%.

Technology upgrade, cost decreasing and benefit increasing

“Crushing between material” work pattern is adopted to reduce wear-resisting type and cost; adjust some impeller structure and craft. Comparing with the earlier equipment, the impeller lifespan is raise up by 30-200% on the situation of same material.

Efficient working, easy maintenance

New lifting device to facilitate customer maintenance of the equipment, saving labor; minimalist design effectively prevent blocking when the moisture content of the raw material is high, reduce downtime, and efficient operation.

Unique design, quality assurance

Equipment transmission parts special sealed cartridge bearing structure prevents leakage, won three national patents; good bearings, reduce transmission failure.

WORKING PRINCIPLE

European Type Impact Crusher use impact energy to crush the materials. When materials enter the working area of plate hammer, they are impacted then crushed by plate hammer at a high speed, and are thrown into the impact device installed at the upper part of the rotor for re-crushing, then rebounded into the working area of plate hammer from the impact scale board for re-crushing. This process is repeated until materials are crushed into demanded granularity and are discharged from lower part of the machine.The granularity and the shape of the materials can be changed by adjusting the gap between the impact frame and the rotor shaft.Spring safety device is adopted behind impact plate of the machine. When non-broken materials enter the crushing cavity, the front and rear impact frame fall.
