  • Characteristics of Raymond Mill

    Inheritance Of Classical Design, Innovation Of Science & Technology

    Raymond Mill adopts the classical pendulum rollers of Raymond Mill on the one hand and change the spring connection structure innovatively on the other hand, which can not only avoid the terrible impact of large materials on the axis and bearings, but also enhance the crushing strength of grinding rollers so as to increase the yielding.

    Lower Electricity Consumption, Higher Economic Profits

    Under an ideal circumstance, Raymond Mill consumes 1.02kW/h when yielding a ton of materials and 1.48kW/h when feeding a ton of materials. Its electricity consumption is lower than that of ball grinding mill of the same level by over 60%.

    Impeller-Type Energy-Saving Fan Having Higher Efficiency

    SBM adopts the high-efficiency impeller energy-saving fan, and the working efficiency of which can reach 85% or above while traditional grinding mills equipped with straight blade fan can reach only 62% of air inducing efficiency. Under the equivalent production requirements, Raymond Mill can realize better powder separating and lower power consumption.

    Lower Energy Consumption - Cambered Air Duct

    Raymond Mill uses the cambered air duct with low resistance. By this, air flow enters the grinding mill tangentially. Compared with traditional straight air ducts, the inlet of this air duct is smooth with little resistance and the outlet is easy for the dispersing of materials which can avoid material piling, effectively reducing energy consumption of the system.

    Digitalized Processing, Higher Precision

    There are tens of lines of numerical controlling machine tools. Operations such as steel plates’ cutting, bending, planing, milling and paint spraying are all controlled numerically. The machining precision is high, especially for the core parts.

    Sufficient Supply Of Spare Parts, Worry-Free Operation

    SBM, whose businesses cover production and sales, takes responsibility for every machine produced by ourselves. We can offer customers technical services about products and original spare parts to ensure the worry-free operation.

    How to solve the problem of reducing the amount of Raymond Mill?

    The accessories of Raymond Mill are very important. High-quality accessories can increase the service life of the machine and effectively improve the efficiency of Raymond Mill. We hereby remind users to consider the following aspects when choosing accessories for Raymond mills:

    First of all, when choosing Raymond mill accessories, you must choose the right accessories according to your own needs. Never pay attention to the price. Low prices and poor quality are commonplace, so you must not just look at the price. If you want to be durable, choose a strong manufacturer and choose a manufacturer with good reputation and high credibility so that you can be guaranteed. Secondly, when choosing Raymond mill grinding parts, the original manufacturer at the time of purchase should be considered, because this is the supporting and most suitable. In this way, the overall coordination of the machine is not easy in the operation. Unnecessary losses and troubles. Although the Raymond mill accessories are only a small part of the whole machine, you must know that the entire Raymond mill equipment is composed of such small accessories, so you can't underestimate its role. It's better to be careful.

    During the use of the Raymond mill, due to different conditions, the output of the equipment may be affected, or there are other problems. Today I will teach you how to avoid the reduction of the output to the customers. Trouble:

    • 1. When the Raymond mill is processing materials, the moisture content of the material is an important reason for restricting the machine's output. When the moisture content of the material is high, it is under the squeeze of the grinding roller and the grinding ring during processing. It may stick to the inside of the machine. In this case, the machine will be out of order and out of stock, which will reduce the output of the machine.
    • 2, the customer needs to process different materials. Under the requirements of a certain fineness of processing a certain type of ore, the Raymond mill can reach an output of one ton per hour, but it is used to process charcoal or other lighter materials. If this is the case, the output will definitely not be reached, so the output of the machine will be low.
    • 3, the hardness of the processed material will also affect. Some customers are processing limestone, and some customers are processing ilmenite. The hardness of ilmenite is quite high. In the case of the same type of machine, the output is the same fineness. It must be different.
    • 4. The fineness that customers need to process is different. If the same is used to process quartz stone, when the 200-mesh fineness and the 400-mesh fineness are required, the output will definitely be different. The lower the fineness, the higher the output.
    • 5. The quality problem of Raymond mill equipment, the so-called quality problems are the key parts. The most critical part of Raymond mill work is the grinding roller and ring. If the quality of the grinding roller is high, the processing capacity will be high and the output will be high. It will definitely go up. If you work long hours, it will still yield high quality.

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.
