GKH1032D Ultrafine Ring Roller Mill is a developed kind of grinding mill with optimized design & structure. It is mainly used in deep processing non-metallic mineral stones, hardness below seven Moh's hardness and humidity below 6%, such as calcium carbonate, kaolin, talc, barite, grammite, feldspar etc. The GK1032D mill mainly consists of the feeder, main unit, classifier, pulse collector, high-pressure blower, electrical control cabinet etc.
Frequency-conversion feeder shall feed material to the central part of upper grinding-plate evenly. The material falls to circle under the centrifugal force and comes down to raceway of ring to be crushed into powder. After grinded in the first raceway, the material goes to the second and third raceway. The air blower inhales the external air into the mill and carries the powder after third grinding-plate into classifier. Classifier wheel makes the coarse powder drop down and then regrinded, the fine powder shall go into cyclone collector together with air current and go down through discharge valve as final product; at the same time, air current with a little dust goes out through blower and muffler after purified by filter.
Raw material is fed into grinding chamber via feed port of upper part, then be grinded between rollers and grinding rings into powders. Powders are blowed into upper part. Qualified particle goes into powder collecting systemthrough classifier wheel, others fall and be grinded again.
In reverse-pulse-jet baghouses, individual bags are supported by a metal cage, Dusty air enters from the bottom of the baghouse and flows from outside to inside the bags. Bags are cleaned by a short burst of compressed air injection. The powder falls into a storage hopper below. This collecting system works with the help of digital sequential timer (PLC) attached to the pulse valves.
Adapting domestic top level electric components, after 20 years' testing. Our electric control or PLC system is very easy to operate, fully automatic operation, and one button stop, It's also easily adjust. Buyer only needs to adjust current and frequency with visible digitals to reach different particle size from 325-3000 mesh.
1. Both product size and fineness are guaranteed. The new YFM grinding mill is able to reach a product fineness of 325 - 2500 mesh one time, while the traditional Raymond mill can only reach a fineness of 400 mesh for the most. It can be used for all kinds of grinding from coarse crushing to ultrafine grinding, with the largest fineness of up to D973um, which drives the revolution in the field of ultrafine grinding.
2. Low investment cost and high output efficiency. Compared to ball mill, air-flow mill and stirred mill, YFM grinding mill has the advantages of lower investment and shorter processing circle, and its finish fineness/efficiency ratio is more than twice that of the machines mentioned above for the same fineness.

GLMF series vertical roller mill is the high-end grinding mill, which adopts the Germany advanced technology and standard. It has been taking the leading position relatively owing to the product design, material selection, quality control and service standard. The vertical roller mill is the most suitable equipment for the customers who need the huge capacity, the intelligent system, the smallest occupation, and the continuously working ability.
The main motor drives the grinding plate to rotate through the reducer, meanwhile, the air flow gets into the mill through air inlet. The materials come out of the screw feeder and fall on the center of the grinding plant, and evenly moved outwards due to centrifugal force. The materials are ground by grinding rollers when passing through the grinding area on the grinding plate, and large size materials will be directly crushed while the small particles form a material bed by extrusion for further inter granular crushing.
The grinded materials keep moving to the edge of the mill until they are taken away by the air current at the vane and collected by the powder collector, the coarse particles in the air flow will drop back to the grinding plate for further grinding when passing through the upper separator under the action of the rotor blade,
However, the iron blocks and other wastes mixed in the materials will move along with the materials towards the edge of the grinding plate due to their own weight and fall into the lower chamber and then be discharged out of the slag discharge opening by the scraping plate at the bottom of the mill tray.
