Euro-style Impact Crusher

Raymond mill originated by Raymond brothers around 1880s. Raymond mill was introduced in China around 1950s. In terms of traditional pendulum roller mill, the R-series grinding mill has been upgraded in many aspects. All of the technical parameters take the leading role in China mill industry. The R-series grinding mill ranges from 2R to 6R, including 2R2713, 3R3220, 4R3216, 4R3218, 4R3220, 5R4121, 5R4125, 6R5127.

Raw material is firstly broken by jaw crusher into required particle size, which are carried by bucket elevator up to the storage hopper. The vibration feeder then conveys the crushed materials at a fixed rate into the grinding chamber of the main unit for pulverizing.
 
The three rollers hung upon the spider-arm are running around the shaft. With the centrifugal force, the four rotational rollers will go around the ring tightly. The raw materials are put up between the rollers and rings by the blade to make the raw materials into powder. The grinded materials are blown up to the classifier, through which the powder is separated by the airflow.
 
Coarse particles fall back down to the mill for regrinding.
 
The needed particles will go into the collector where products will be removed through the discharge opening. The purified air flows to the air blower through the pipe above big cyclone collector. Air flue is circular type. Air stream in all pipelines is negative pressure except for that in the air blower and grinding chamber, which improved the working condition in the workshop.
 
Wind volume in air flue increases as the moisture in material changes into vapour leaking in from the flange conjunctions and feed opening. Added air volume is transporting through the air blower and after-wind pipe, to simple collector. The end powder enters the collector with air stream and discharged from discharge valve.

1. The grinding mill is in stereo-chemical structure, consume small floor space. The equipment has strong systematic because it can organize an independent and complete production system of raw material crushing, transporting, grinding to production collecting, storing and packing.
 
2. Driving system (double gearing, single gearing and reducer) and classify system (classifier and analyzer) can be configured according to the material or customer requirement, in order to ensure best operation condition.
 
3. Depending on the material to configure the pipe and blower system, in order to reduce wind resistance and pipe abrasion, ensuring high capacity.
 
4. Applied high quality thicken steel to produce important parts, applied high performance wear-resistant material to produce wear-resistant parts. The equipment has high wear-resisting property and reliable operation.
 
5. Centralized controlled electric system realized unmanned operation and easy maintenance.
 
6. Pulse exhaust system can be applied to deal with remain air. Filtering efficiency can reach 99.9%.
