  • Overview

    Limestone industrial grinding mill is a kind of mining mill, mainly used to process ore products such as limestone.
    Limestone is widely distributed and rich in reserves. It is a valuable resource with a wide range of uses. It is usually used as a building material and an important raw material for many industries. It can be used to produce portland cement, and produce coating grade heavy calcium carbonate products for high-end papermaking. Used as a filler in the production process of plastics and coatings. Production of foundry sand for machinery manufacturing. Production of desulfurization absorbent. Used to produce active lime and passivated lime. Limestone is calcined to produce active lime, and can be processed to produce passivated lime.

    The commonly used processing technology of limestone is to use a special mill for mechanical pulverization to make it into powder. After the limestone is directly pulverized, heavy calcium carbonate can be obtained. According to the different pulverization fineness, there are four different specifications in the industry: single fly, Double fly, three fly, and four fly are used in various industrial sectors.

    Limestone Industrial Grinding Mills Raymond Mill

    Limestone industrial grinding mill Raymond mill is a new type, high-yield, high-fine powder milling equipment with closed-circuit circulation. The Raymond mill is suitable for small and medium-sized mines, chemicals, building materials, metallurgy, refractory materials, pharmaceuticals, cement and other industries. After years of practice and continuous improvement, the structure of our company's limestone Raymond mill has been perfected day by day. It has been widely used in limestone, calcite, potash feldspar, talc, marble, fluorite, lime, etc. More than 280 non-flammable and explosive mineral, chemical, construction and other industries with Mohs hardness not greater than 7 and humidity below 6 High-fine powder processing of various materials, the particle size of the finished product can be adjusted arbitrarily within the range of 80-600 mesh, and some materials can reach 600 meshes. Through the joint action of the analyzer and the fan, it can meet the requirements of different users.

    Advantages of Limestone Industrial Grinding Mill Raymond Mill

    1. Low investment: Compared with ordinary mills, the limestone Raymond mill has high efficiency, low power consumption, small footprint, and small one-time investment;

    2. The fineness of the finished product is high: the grinding roller is tightly rolled on the grinding ring under the action of centrifugal force, so when the grinding roller and the grinding ring are worn to a certain thickness, the output and fineness of the finished product will not be affected;

    3. Long life: The grinding roller and grinding ring of the limestone industrial grinding mill Raymond mill are made of wear-resistant materials and have a long service life, thereby eliminating the shortcomings of the short replacement cycle of the wearing parts of the centrifugal crusher;

    4. Small environmental pollution: the grinding process is a fan-mill shell-cyclone separation machine-fan circulating operation, so it has less dust than a high-speed centrifugal crusher, and the operating workshop is clean and the environment is pollution-free;

    5. High thermal efficiency and energy saving: The limestone industrial grinding mill Raymond mill is used in conjunction with the pulverized coal furnace, which has simple operation and low maintenance cost. Because the pulverized coal is fine, the furnace is completely burned and the thermal efficiency is high.

    The Working Principle of Limestone Industrial Grinding Mill Raymond Mill

    The main work process of the limestone industrial grinding mill is to drive the central shaft to rotate through the transmission device. The upper end of the shaft is connected to the plum blossom frame. The frame is equipped with a grinding roller device and forms a swing fulcrum. It not only revolves around the center, but also the grinding roller revolves around the grinding ring. At the same time, the grinding roller itself rotates due to friction. The lower end of the plum blossom frame is equipped with a shovel knife system, which is located at the lower end of the grinding roller. During the same rotation of the shovel and the grinding roller, the material is shoveled and fed between the rings of the grinding roller to form a cushion layer, which is produced by the rotation of the grinding roller The outward centrifugal force (ie, squeezing force) crushes the material, and thus achieves the purpose of milling.

    The analyzer drives the 60 blades on the turntable to rotate through a speed-regulating motor and a two-stage deceleration to form a classification effect on the powder. The speed of the blade speed is adjusted according to the size of the finished powder. When obtaining fine-grained powder, it is necessary to increase the speed of the blade to increase the contact between the blade and the powder, so that the undesirable powder is thrown by the blade to the outer wall and separated from the air flow, and the coarse powder falls into due to gravity. The grinding chamber is re-grinded, and the qualified finished powder is sucked into the cyclone collector by the blade along with the airflow. After the airflow and the powder are separated, the powder is collected.
