The Raymond mill, also known as the Raymond grinding mill, is a commonly used grinding equipment in the pulverizing industry. It can effectively pulverize materials with feed particle sizes less than 30mm, such as talc, kaolin, barite, coal, and cement clinker. It features fine output, high screening rate, low power consumption, and small floor space. When choosing equipment, customers are quite concerned about how much fineness the finished product can reach and whether it can meet their production requirements. So, what is the finest fineness that a Raymond mill can achieve? How many tons are ground in one hour? Now let’s have a brief chat about it.
How many tons can a Raymond mill grind in one hour?
The answer to this question needs to be comprehensively judged based on the material being ground and the fineness of the output. The hardness and fineness requirements of different ores vary, and the production capacity is bound to be high or low. Generally speaking, the Shanghai Cronus Raymond mill can grind about 1 to 22 tons of materials per hour. However, the output parameters provided by most manufacturers are average values. The actual output is also related to the hardness, size, humidity of the material, as well as the performance of the equipment.
What is the finest mesh that a Raymond mill can grind?
At present, the particle size of the finished grinding products produced by most manufacturers of Raymond mills is basically around 0.173-0.044mm, which is between 80 and 325 mesh. Some merchants also produce new Raymond mills, claiming that the fineness of the finished grinding products can reach 80 to 600 mesh. However, in actual production, Most grinding powder manufacturers rarely use Raymond mills to grind materials to 500-600 mesh. When the same material is ground to around 500-600 mesh by a Raymond mill, not only does the output decrease, but also the grinding rollers need to have a greater grinding force.
It should be known that the grinding force of the grinding roller comes from the centrifugal force generated when the grinding roller assembly rotates around the center. To obtain a greater grinding force, that is, the centrifugal force, the central shaft speed of the Raymond mill needs to be increased to over 145r/min. At such a high speed, the vibration of the Raymond mill will increase, which can easily lead to the breakage of the anchor bolts of the Raymond mill main unit and the cracking of the main unit cover cylinder. This will shorten the service life of the Raymond mill, which is not worth it.
Therefore, the Raymond mill can grind up to 600 mesh at the finest, but its output is very low, with an hourly output of only a few hundred kilograms. Therefore, taking all factors into consideration, it is recommended that when using a Raymond mill for grinding powder, the finished product particle size be controlled between 80 and 325 mesh, which is more reasonable and scientific.
