    Material: Limestone, calcite, dolomite, petroleum coal, gypsum, barite, marble, talc, coal powder, etc.

Working Principle

After jaw crushers break large bulky materials to smaller ones, elevators work to send materials to the hopper. Then, by electromagnetic vibrating feeders, broken materials are evenly and quantitatively sent to the grinding chamber of MTM Medium-speed Grinding Mill. After grinding, materials are blown away by airflow to the powder concentrator for classifying. Under the action of the impeller of powder selector, materials which fail to meet fineness would be sent back to grinding chamber to get another grinding while qualified powders would be collected by cyclone powder collector and discharged from the bottom as finished products. And, after that, the airflow would go into the fan along with the air return duct at the top of cyclone power collector. This system adopts a closed circuit and runs under positive and negative pressure. Because materials have a certain content of moisture, heat generated during grinding may lead air evaporation or swell in the grinding chamber so that the amount of airflow increases sharply. Besides, if the feed port and joints of pipelines are not sealed well, external air may intrude the grinding mill and lead imbalance of airflow. So, SBM arranges exhaust valves at the air outlet of the fan to induce redundant air into the bag filter. After purifying, the redundant air is discharged. This arrangement can achieve both the balance of airflow and the eco-friendly production.

Performance

Raymond Mill structure:

Raymond Mill mainly consists of main engine, analysis machine, blower, finished cyclone separator, piping device, motor and other components, including the host from the rack, into the volute, blade, roller, grinding ring, casing and motor Composition, auxiliary equipment jaw crusher, bucket elevator, electromagnetic vibration feeder, electric control cabinet, the user can choose according to the scene of the situation.

Raymond machine work process:

The whole structure of Raymond Mill is composed of jaw crusher, bucket elevator, electromagnetic feeder, electric control motor and so on, which can be equipped with main engine, analyzer, piping device, blower, and according to user's needs. Material crushed to the required size, the material will be sent by the hoist to the hopper, and then by the vibration feeder to the material evenly into the Raymond Mill main machine grinding room, due to the rotation of centrifugal force, roller out Swing, squeeze in the grinding ring, shovel shovel from the material to the grinding roller and grinding ring, because the roller rolling to achieve the purpose of grinding. Material after grinding the fine powder with the blower of the circulating wind was brought into the analysis machine for sorting, fineness of the material back to the heavy grinding, qualified powder with the air into the finished product cyclone collector, the powder tube discharge, That is finished.

In the mill room due to the grinding material in a certain amount of water, grinding heat, water vapor evaporation, and the machine is not tightly connected to the pipeline, the outside world was inhaled, so that the circulating pressure increased to ensure that the mill in the negative pressure state of work , The increase in air flow through the residual duct into the dust collector, was purified and discharged into the atmosphere.

Performance characteristics of raymond mill

Raymond Mill a few points to note

Raymond grinding wear is a normal situation, there will be a serious wear and tear of the situation will be replaced, like a roller, grinding ring these are more easy to wear Raymond grinding parts, the user in the purchase of Raymond Mill accessories will be more Prepared several sets, timely replacement on it. Lei Meng grinding parts of the wearing parts, including roller, grinding ring, bearings, blade, etc., ranging from a few months, as many as a year or two, are not the same.

Raymond grinding equipment can be flexible to meet the basic small milling operations, centrifugal milling machine can be used for dry milling and wet milling two sorting methods, equipment, internal parts of the use of long-term, efficient energy-saving, which is the future Equipment development trend, and the sealing is good, to avoid the dust removal device; centrifugal Raymond Mill covers an area of ​​small, with crushing high hardness materials, energy efficient processing. Raymond grinding work, ultra-fine grinding mill roller shaft is often affected by the impact load, but also need to have a certain impact toughness, fatigue strength and performance.

Raymond Mill before the installation of the operator must carry out the necessary technical training to understand the principles of Raymond grinding parts performance, familiar with the operating procedures. At the same time to have the necessary maintenance tools and grease and the corresponding Raymond Mill. However, in the summer high temperature, some parts of the Raymond mill parts also need to be carefully maintained, Raymond Mill after a period of time, for maintenance.

How to make Raymond fineness finer

Raymond grinding degree is a certain range, the conventional Raymond grinding degree can only reach about 325 heads, before encountering a case, the user asked the fineness of the powder must reach 325 mesh to fine, after repeated Test, the final conclusion is that the fineness of the powder eventually failed to reach 100% compliance, through the sieve screen sieve residue is minimal, but even if the percentage of zero, or not 100% The So I summed up, Raymond Mill can reach 325 mesh, but the sieving rate can only reach 99 percent, can not all thinner than 325 head. So how to make Raymond Mill fineness finer fineness, we first think of the method is to reduce the fan air volume and increase the speed of the grading machine, but without losing the efficiency of the case, these do limit is 325 head , The real method is to transform the wind election system, that is, the disc-type classification into a squirrel cage grading wheel, the initiative of the new Raymond Mill and ultra-fine Raymond grinding the difference, so if you want to use Raymond Mill Processing ultra-fine powder, the proposed use of SBM mechanical production of ultra-fine Raymond Mill.
