Buy an environmental protection mill roller mill, and the difference between the working principle of the traditional mill

Working principle of LM series vertical mill: LM vertical mill is mainly composed of grinding roll assembly, grinding disc assembly, hydraulic station, transmission arm assembly, powder concentrator, main reducer, motor, body, main reducer lubrication station, hydraulic station, PLC electric control cabinet, etc. During operation, the main motor drives the grinding plate to rotate through the reducer. At the same time, the hot air enters the vertical mill from the air inlet, and the materials fall in the middle of the grinding plate from the feeding port. Under the action of centrifugal force, the materials move evenly from the middle of the grinding plate to the edge. When passing the grinding roller area on the grinding plate, the large materials are crushed directly by the grinding roller, and the fine materials are crushed to form a bed for inter particle crushing. The crushed materials continue to move towards the edge of the grinding plate until they are taken away by the strong air flow at the wind ring, while the larger granular materials fall onto the grinding plate again to continue crushing. When the materials in the air flow pass through the upper separator, the coarse particles return to the grinding plate again for grinding under the action of the rotor blades. The qualified fine powders go out of the mill together with the air flow and are collected by the system's powder collector. The collected powders are the products milled by the vertical mill. When iron blocks and other sundries mixed with materials move to the edge of the grinding plate along with the materials, they cannot be blown up by the wind due to their heavy weight, and fall to the lower chamber of the mill and are scraped into the slag discharge port and out of the machine by the scraper installed at the bottom of the grinding plate.

2. MTW European version mill

Working principle of MTW European version mill: the qualified materials crushed by MTW European version mill are sent to the main machine mill room for grinding uniformly, quantitatively and continuously through the frequency conversion belt feeder. The grinded materials are sent to the powder concentrator by the air flow of the fan for grading. Under the action of the analyzer, the materials that do not meet the fineness requirements fall into the grinding chamber for re grinding. The qualified materials flow through the pipeline into the cyclone powder collector for separation and collection, and are discharged by the discharge device as finished powder. The separated airflow enters the fan through the return air pipe at the upper end of the cyclone dust collector. The system operates under positive and negative pressure, and the equipment is equipped with pulse dust remover, which is environmentally friendly.

3. 5X European version intelligent mill

Working principle of 5X European version intelligent pulverizer: 5X series European version pulverizer is a vertical structure, mainly composed of host, fan, powder concentrator, special dust remover, cyclone dust collector, pipeline device, motor and other equipment. The supporting auxiliary equipment can be crusher, elevator, belt conveyor, electromagnetic vibration feeder, silo, control cabinet, etc. The materials are uniformly sent to the grinding chamber of the main machine through the feeding device. Under the action of centrifugal force and blade, the materials are crushed by squeezing and grinding between the grinding roller and the grinding ring. The crushed materials are blown to the powder concentrator under the action of wind force for separation. The qualified materials after separation enter the cyclone collector through the pipe for collection. The materials that do not meet the fineness requirements return to the main machine for grinding again. The whole air flow system of the mill is closed circulation and circulates under negative pressure. First, the air flow generated by the fan enters the cyclone powder collector along with the material through the pipe, the powder collector separates the material from the air flow, and the air flow returns to the fan through the return air pipe, forming an air circulation system; Secondly, the surplus gas and fine powder are sent to the dust remover for filtering through the pipeline, the dust is collected by the dust remover, and the surplus gas is discharged after purification, effectively protecting the environment.

4. High pressure hanging roller mill

Working principle of high pressure suspension roller mill: the whole set of equipment of high pressure suspension roller mill is composed of host, reducer, analyzer, pipeline device, blower, dust remover, jaw crusher, bucket elevator, electromagnetic vibration feeder, electric control system, etc. When the main machine motor drives the main shaft to rotate through the transmission device, the blade mounted on the blade carrier rotates synchronously with the grinding roller, and the grinding roller rotates around its own shaft while rolling in the inner circle of the grinding ring. The motor drives the Analyzer to rotate through the transmission device. The higher the impeller speed is, the finer the powder will be separated. In order to ensure that the mill works under negative pressure, the increased air flow is discharged into the bag type dust remover through the exhaust pipe between the fan and the host, and then discharged into the atmosphere after purification.

5. LUM superfine vertical mill

Working principle of LUM superfine vertical mill: LUM superfine vertical mill is mainly composed of motor, reducer, grinding roller device, grinding plate device, pressurizing device, powder concentrator, machine body and oil station. The main motor drives the grinding plate to rotate through the reducer, and at the same time, the air enters the mill from the air inlet. The materials fall in the middle of the grinding plate through the feeding port of the screw feeder. Under the action of centrifugal force, the materials move evenly from the middle of the grinding plate to the edge. When passing the grinding roller area on the grinding plate, the large materials are directly crushed by the grinding roller, and the fine materials are crushed into a bed for inter particle crushing. The crushed materials continue to move towards the edge of the grinding plate until they are taken away by the strong air flow at the wind ring, while the larger granular materials fall onto the grinding plate again to continue crushing. When the materials in the air flow pass through the upper separator, the coarse particles return to the grinding plate for grinding under the action of the rotor blades. The qualified fine powders are grinded together with the air flow and collected by the system's powder collector. The collected powders are the products of the ultra-fine vertical mill. When iron blocks and other sundries mixed with materials move to the edge of the grinding plate along with the materials, they cannot be blown up by the wind due to their heavy weight, and fall to the lower chamber of the mill and are scraped into the slag discharge port and out of the machine by the scraper installed at the bottom of the grinding plate.

6. MW ring roller fine grinding mill

Working principle of MW ring roll micro powder mill (medium speed micro powder mill): The whole set of MW ring roll micro powder mill (medium speed micro powder mill) includes hammer crusher, bucket elevator, storage bin, electromagnetic vibration feeder, host, powder concentrator, diffusion type double cyclone powder collector, pulse dust collector, high-pressure fan and muffler. The motor of the main machine drives the main shaft and turntables of each layer to rotate through the reducer, and the turntable drives dozens of ring rollers to roll and rotate in the grinding ring raceway through the pin. The large materials are crushed into small particles by the crusher and then sent to the storage bin by the elevator. The electromagnetic vibration feeder evenly sends the materials to the middle of the upper rotary table. The materials disperse to the circumference under the centrifugal force and fall into the roller path of the grinding ring, which is punched, rolled and ground by the ring roller. The materials fall into the second and third layers after being crushed by layers. The suction of the high-pressure centrifugal fan sucks the external air into the machine, The coarse powder after the third layer of crushing is brought into the powder concentrator. The worm flow generated by the rotating worm wheel in the powder concentrator makes the coarse particle materials fall back for regrinding. The fine powder enters the cyclone powder collector with the air flow and is discharged by the discharge valve at the lower part of the cyclone powder collector, which is the finished product. The air flow with a small amount of fine dust is purified by the pulse dust remover and discharged through the fan and muffler.
