raymond mill is an energy-efficient grinding equipment. raymond mill is not a panacea. he has a certain range of use. it is not that any ore chemical raw materials can be used for raymond grinding. raymond mill is used for powders with a humidity below 6% and hardness below 9.3, and is non-flammable and explosive. under normal circumstances, the production efficiency of raymond mill is considerable, but the production efficiency of raymond mill is not constant.
in the actual work, in the normal operation process, master the correct method and better maintenance. maintenance, mastering certain operating skills and precautions will definitely increase the production efficiency of raymond mill. in addition to rayleigh's own factors, some objective factors also have a great impact. here are four brief introductions.
1. under normal circumstances, the higher the hardness, the lower the output, the higher the hardness of the material will reduce the production efficiency of the raymond mill, and the wear of the parts of the raymond mill will also increase.
2. the higher the viscosity of the material, the higher the adsorption capacity, the greater the possibility of not being selected by the wind, and the lower the efficiency of raymond milling.
3. material humidity: raymond mill is suitable for products with a humidity below 6%. the material with high water content will stick to the inside of the raymond mill after grinding, and it will also cause blockage during transportation, which will obviously affect the efficiency of raymond mill.
4. the composition of the material: the normal use of raymond mill can produce fineness between 80-325 mesh. if the material contains more fine powder, it will adhere to the inner wall of raymond mill. it is best here. the vibrating screen was used before, and the size of the powder suitable for raymond milling mechanism was selected to be the best.
raymond mill is a low-speed grinding equipment, and the raymond mill main engine speed is generally in the range of 150-260 rpm. in the case of long-term work, raymond grinding chamber will produce a certain temperature, but due to the low speed of raymond mill and the cooling of the fan of raymond mill, the temperature of raymond mill chamber is up to 50 degrees celsius.
how to solve the high temperature problem of raymond mill grinding chamber, the raymond mill temperature is mainly caused by the friction heat generated during the material crushing process. because the raymond mill wind selection system uses the circulating air system, the heat dissipation problem is the use of raymond mill is particularly important during the use of the raymond grinding roller assembly and the properties of the material being processed (materials that are required for temperature).
the main method to solve the raymond mill temperature is to use a better dust removal method. for example, a pulse dust collector is used. the pulse dust collector has good gas permeability, small dust, and automatic dust cleaning function, and can timely discharge high temperature air in the mill. inhalation of room temperature air in order to reduce the temperature of the raymond grinding chamber.
in the milling line, the motor is an indispensable part of the grinding process. for the 4r raymond mill, the size of the motor affects the health of the equipment and the power consumption. therefore, it is very important to understand the configuration knowledge of the 4r raymond mill motor.in the raymond pulverizer production line, the raymond pulverizer motor is mainly composed of a main machine, an analysis machine, a hoist, a blower, a crusher, and an electromagnetic vibrating feeder. among these components, the power matching of the motor is directly related to whether the device can operate normally.
in the raymond pulverizer production line, if the particle size of the ground material is too large and needs to be crushed, the jaw crusher is a relatively common equipment. in general, the motor configuration power of the crusher is small.the hoist is the main conveying device between the silo and the crusher, and its power is usually around 3kw. moreover, in the grinding production line, the hoist can be optional, so the hoist motor is not a necessary equipment for the 4r raymond mill.
electromagnetic vibrating feeder motor. in order to better ensure the uniform and uniform feeding of the raymond mill, the electromagnetic vibrating feeder is generally configured because it directly affects the operation of the equipment, the quality and yield of the finished product. under normal circumstances, the electromagnetic vibration feeder power is about 150kw.
the main motor of 4r raymond powder grinding machine is the main power to realize the grinding and grinding of the grinding roller. in general, its motor power is 90kw, which is an essential equipment in the grinding production line.
the blower is connected to the volute of the main machine, from which a large amount of wind is blown and then enters the grinding chamber. since the blower is the main source of air volume in the entire grinding production operation, it has the characteristics of large energy loss and high motor power in the entire production line. the general 4r raymond pulverizer blower motor power is about 110kw.
there are a lot of raymond mill models on the market. how to choose the raymond mill model correctly is a topic of common concern to customers. when purchasing the raymond mill, the mill production company should be based on its own production needs, plus raymond mill.
the manufacturer introduces the production of various models to choose the raymond mill equipment that suits you. it is very important to purchase raymond mill to choose the right raymond mill model. as a manufacturer of raymond mills, we have accumulated so many years of production and sales experience, and it is inevitable that some customers will use it for a period of time after purchase.
for the raymond mill model, if the model is selected and the later production can be easily handled, then the choice of this machine is very successful, and the customer will alleviate a lot of burden. it is obvious how important it is to the raymond mill model. as a professional raymond mill manufacturer, some scarce materials may not have been touched. we will not arbitrarily promise customers what kind of raymond mill models to use, and they will ask customers to wait for the test machine or mail materials to test the machine.
some customers blindly purchase raymond mills without experience, and there will be insufficient production. for the choice of raymond mill models, especially the large raymond mills mainly depends on the properties of the materials processed by the miller, including the color, structural properties, hardness, humidity and other factors of the mineral; the installed capacity of the machine, that is, the power consumption and the required amount of powder unit time, for the powder with special requirements, the user should pay attention to the particle shape of the powder product. other non-metallic mineral powder products are mostly white minerals, so when choosing a large raymond mill model, the secondary pollution of the product should be paid more attention.
