The machine adopts the advanced structure of similar products at home and abroad, and is updated and improved on the basis of the same industry Raymond Mill. The equipment is more efficient than ball mill, low power consumption, small footprint and small one-time investment. Roller in the role of centrifugal force tightly crushed on the grinding ring, so when the roller, grinding ring wear to a certain thickness does not affect the finished product yield and fineness. Roller, grinding ring replacement cycle is long, thus eliminating the shortcomings of the centrifugal crusher parts replacement cycle shortcomings. The air blower of the machine is in the fan - grinding shell - cyclone - fan circulating circulation operation, so less than the high-speed centrifugal grinder dust, operating workshop clean, the environment pollution.
Raymond Mill, also known as Raymond Mill, Raymond machine, is to replace the ball mill processing ore powder of a milling machine, Raymond Mill grinding roller in the role of centrifugal force tightly pressed on the grinding ring , So when the roller, grinding ring wear to a certain thickness does not affect the finished product yield and fineness. Raymond Mill grinding roller, grinding ring replacement cycle is long, thus eliminating the shortcomings of the centrifugal crusher parts replacement cycle short.
Raymond Mill is suitable for non-flammable and explosive minerals such as barite, calcite, potassium feldspar, talc, marble, limestone, ceramic, glass and other Mohs hardness not more than 7, humidity below 6% , Building materials, metallurgical and other industries more than 280 kinds of materials, milling processing, finished grain size in the range of 80-325 within the arbitrary regulation.
SBM Mine Machinery Co., Ltd. production of Raymond Mill series of products are:
3R2615,3R2715,3R3016,4R3016,4R3216,5R4121, etc., should be the development of the market The company has launched a large industrial 6R Raymond Mill equipment and 7R Raymond Mill.
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.
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.
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.
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.
