Dolomite Raymond Mill, Dolomite Raymond Machine For Sale in Pakistan [Processing ability]: 0.2-50 t/h [Max feeding size]: 35mm [Final product size]: 80-325Mesh [Range of application]: calcium carbonate, barite, dolomite, calcite, limestone, kaolin, bentonite, marble, gypsum, quartz, feldspar, clay, talc, fluorite, clay, white mud, mica, refractory material, glass, total about 1000 kinds of materials. Working Principle of Dolomite Raymond Mill, Dolomite Raymond Machine The standard configuration of Raymond Mill consists of main unit, reducer, powder classifier, cyclone powder collector, dust cleaner, blower, control cabinet motor and pipes. The optional accessories include crusher, bucket elevator, feeder. Big materials are crushed by jaw crusher to the required particle sizes, and carried by bucket elevator to the storage hopper, and are fed evenly and continuously by vibrating feeder into the main unit for grinding. The grinded powder are carried by the airflow from the blower to the classifier to be classified, the particles which meet the fineness enter cyclone collector through pipe, and are separated and collected there. They are discharged at the discharging valve to become finished products; The airflow is sucked to the blower by return pipe on the top of cyclone collector. The whole airflow system is a sealed circulation, and is circulated under positive and negative air pressure.
HGM grinding mill is mainly used for grinding the material with middle and low hardness, below 6% moisture, and the material should be non-explosion and non-flammability, such as: calcite, chalk,limestone, dolomite, kaolin, bentonite, steatite, mica, magnetite,iolite, pyrophillite, vermiculite, meerschaum, attapulgite, diatomite, barite, gypsum, alunite, graphite, fluorite, phosphate ore, potassium ore pumice, etc. Ultrafine Grinding Mill Working Principle When the grinding mill is at work, the main bearing and each dial are driven by electromotor through reducer, and all the grinding rollers are rolling in the ring channels driving by dial through plunger. The materials are driven to the edge of the turn plate by the centrifugal force and fall down into the grinding chambers. The high-pressure air blower constantly inhales air, airflow with crushed materials are brought to classifier whose high-speed impeller will screen the airflow: The unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector. Most of the qualified powders will fall and exit from the discharging valve at the bottom; A small proportion of the fine powders, with airflow, moves to the dust cleaner. The materials from the above two lots are sent by the conveyor to get finished powders packed. In addition, filtered clean air will be emitted from muffler in the end.

Dolomite is a carbonate mineral composed of calcium magnesium carbonate. Dolostone (dolomite rock) is composed predominantly of the mineral dolomite with a stoichiometric ratio of 50% or greater content of magnesium replacing calcium, often as a result of diagenesis. Limestone that is partially replaced by dolomite is referred to as dolomitic limestone. Raw dolomite first enters jaw crusher to be crushed to smaller size. They are lift to storage room by elevator. Vibrating feeder will feed materials into grinding chamber evenly and gradually. After being grinded, the quartz powder will be blow to cyclone by blower. Then the dolomite powder will be transferred to storage room through pipes, and then will be discharged as final products. >>The Application of dolomite ultrafine powder grinding mill: HGM series dolomite ultrafine powder grinding mill is mainly applied to non-inflammable, non-explosive and brittle materials with Mohs hardness under six. Such as calcite, chalk, gravel, dolomite, kaolin, gypsum, etc, totally more than 100 kinds of materials. Product fineness can be controlled between 325~2500 mesh. >>Working Principle of dolomite ultrafine powder grinding mill: The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of rollers, which are rolling in the ring, are driven by dial through plunger. After crushed by hammer crusher, the big materials become small ones and are sent to storage hopper by elevator and further sent to the middle of first dial evenly by the electromagnetic vibrating feeder and feeding pipe. The materials will be driven to the edge of dial by centrifugal force and fall down into the ring, crushed and grinded by roller, and become powder after production of three rings. The high pressure centrifugal blower will inhale air from outside and blow the crushed materials to classifier. The rotating turbo in the powder concentrator will make the coarse powder materials return to the mill and reground, while the fineness will mix with the air and go into the cyclone and be discharged in the discharge bin, which is at the bottom of it. The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler. Should you have any questions, please do not hesitate to contact me.
Dolomite Mill can be used to grind and process variety kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6% such as dolomite, limestone, gypsum, barite, carbonate calcium, etc, in mining, construction, chemical industry, etc. Structure: 01. Dolomite is crushed by jaw crusher or hammer crusher to the size required which is suitable for the Dolomite Mill. 02. Then the crushed dolomite are elevated into a hopper by bucket elevator from which the dolomite is transported through the electro-magnetic vibrating feeder evenly and continuously into the grinding chamber for dolomite grinding mill. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the dolomite, send to the middle between ring and roller to accomplish the grind. 03. After this, the ground dolomite are carried by the air from the blower into the powder separator (Analyzer Machine) for screening. The fine dolomite powders are blow into the cyclone powder collector and are poured out through the output-powder valve as the final products, and the corase dolomite after the screening will be recycled back into the grinding chamber for regrinding. The set?s airflow system is closely sealed up and circulated under condition of negative and positive pressure. OUR ADVANTAGE: 1. The whole dolomite mill plant (Raymond Mill) is vertical structure of strong systematic characteristic, so it occupies small area. From crushing of dolomite to grinding and packing is an independent production system. 2. Compared with other milling plants, its passing ratio achieves 99%, this is what other mill cannot reach. 3. Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably. 4. Main parts of the whole plant are made from cast and steel of high quality. The technics is so subtly that insures the durability of whole plant. 5. The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.
