grinding mill types

With the continuous development of industrial production, the market development and demand of various chemical raw materials such as grinding, ore milling, filler production, and power plant desulfurization have driven the rapid development of the industrial mill industry. Many different types and different types of mill equipment have been derived based on different raw materials and different product requirements. So the problem is, in the face of so many mill manufacturers and such complex product types, how to choose the most suitable mill cost equipment that can meet your needs? Here, SBM Heavy Industry will introduce you how to choose the best equipment.

First of all, before the purchase, most users will contact the mill manufacturer through friends introduction, advertising inquiries, e-commerce network search, etc., and compare them in many ways. SBM Heavy Industry tells you that the way to consult is not the main problem. The key is to go to the manufacturer for on-the-spot investigation after initial consultation and understanding. On the one hand, you can see the company scale, production status, product quality, etc. On the one hand, it has also been avoided by misleading or deceiving by non-entity companies such as various network companies, intermediaries, and trading companies.

Secondly, according to your own needs, you can choose and investigate equipment. At present, there are many types and models of mills, and there are corresponding equipment types and models for different fineness and output. The requirements are clear, and the requirements for raw materials, feed size, finished product fineness and output requirements are relatively clear, so come again. Listen to the manufacturer's suggestions and comments. Remember not to be cheap or greedy. After all, if you pay for the price, you don't choose expensive, you don't choose it, you only choose the right one. Only the product that suits you best is the best product.

There are several types of milling equipment

  • Introduction to Raymond Mill
  • Raymond mill is also known as Raymond machine, mill, and lightning machine. Raymond Mill is a widely used grinding equipment for mines, cement plants and chemical plants. It is one of the important equipment for deep processing of non-metallic minerals. Due to the stable performance, strong adaptability and high cost performance of Raymond grinding, it has been widely developed in the field of ultra-fine powder applications.

    The material is uniformly and continuously fed into the main machine for grinding, and the ground powder is taken out by the circulating airflow of the blower, and classified by an analyzer above the main body of the Raymond mill. The powder with fineness conforms to the specification, enters the cyclone collector with the wind flow, and is discharged into the product through the powder discharge tube. The airflow flows into the blower from the return duct at the upper end of the large cyclone. The entire air duct system is closed and mostly flows under negative pressure. Since the material to be ground contains moisture, it evaporates into gas during the grinding and gas leaking into the duct under the action of the negative pressure, resulting in the most increase of the wind in the circulation air passage. The increased air volume is introduced into the dust box from the blower and the residual air duct in the main engine. A number of fine powders brought along with the wind flow are collected from the exhaust pipe and discharged into the atmosphere.

  • Vertical grinding principle
  • Vertical mill is an ideal large-scale grinding equipment, widely used in cement, electric power, metallurgy, chemical, non-metal mines and other industries. It integrates crushing, drying, grinding and grading and conveying. It has high production efficiency and can grind the bulk, granular and powder raw materials into the required powdery materials.

    The motor drives the grinding disc to rotate through the reducer, and the material falls from the feeding opening to the center of the grinding disc, moves to the edge of the grinding disc under the action of centrifugal force and is crushed by the grinding roller, and the pulverized material overflows from the edge of the grinding disc and is simultaneously from the nozzle ring ( Wind Ring) The high-speed upward hot air flow is brought to the high-efficiency classifier integrated with the vertical mill. The coarse powder is sorted by the separator and returned to the grinding disc for re-grinding; the fine powder is ground with the airflow and is collected in the system. Collected in the dust device, that is, the product. The coarse-grained material that has not been taken up by the hot air flow and the accidentally entered metal parts fall from the wind ring, are scraped off by the scraping plate, and are again ground by the externally circulating bucket lifter.

  • High pressure mill
  • The advanced pressure mill has advanced technology, reliable performance and high output. The equipment makes up for the defects of the traditional mill in terms of its scope of application, output, fineness, energy consumption and service life. In the design, the needs of desulfurization and milling are fully considered, and the desulfurization equipment can be perfectly matched to improve the desulfurization efficiency. Therefore, it has become the first choice for desulfurization and powder production at home and abroad.

    In the high-pressure pendulum mill, a high-pressure spring with a pressure of 1000-1.5 kg is fastened on the roller hanger. After starting work, the grinding roller rotates around the main shaft, and under the pressure of the high-pressure spring and the centrifugal force, it is close to the grinding ring, and its rolling pressure is 20% higher than that of the Raymond mill under the same dynamic condition, so the output is greatly improved.

    When the material to be ground enters the grinding chamber, it is shoveled by the blade and sent to the grinding roller and the grinding ring for rolling. The powder after rolling is brought into the analysis machine along with the circulating air of the blower, and the qualified fine powder is introduced into the cyclone with the airflow. The powder is the finished product, and the large particles fall back to the regrind. The circulating air is returned to the blower and the above process is repeated, and the residual air is purified by the bag filter.

    When the grinding roller and the grinding ring reach a certain degree of wear, adjust the length of the high-pressure spring to maintain a constant rolling pressure between the grinding roller and the grinding ring, thereby ensuring stable production and fineness.
