02Product Brief Introduction

  • Low investment cost.

    Set grinding, drying, sorting, transportation in one, simple structure, compact layout, open air layout, greatly reduce investment cost.

  • Transmission system, high bearing capacity.

    Compared with the traditional vertical mill, our transmission reducer adopts a new structure, making the machine has a greater bearing capacity.

  • Hydraulic device, easy maintenance

    The use of hydraulic control system, with the change of material self-regulation pressure, so that the mill to maintain the state, reduce energy consumption, prolong the life of roller sleeve, liner.

  • Thin oil lubrication, reliable operation

    Vertical oil station, automatic protection system, make the device safe and reliable operation.

  • A variety of powder selection, widely applicable.

    Equipment according to the requirements of different materials, fineness, choose different structure of powder selecting machine.Selecting machine adopts frequency conversion speed regulation, particle size distribution is more uniform, fineness is easier to adjust.

  • Electric control system, high degree of automation:

    Equipped with electric control system, can realize PLC, centralized and DCS control, to meet customer needs.

03Working Principle

SRM Series Vertical Mill

The main motor drives the grinding plate to rotate through the reducer. At the same time, hot air enters the vertical mill from the air inlet. The materials fall in the center of the grinding plate through the feed inlet. Under the action of centrifugal force, the materials move evenly from the center of the grinding plate to the edge. When passing through the grinding roller table area on the grinding plate, they are rolled by the grinding roller and large materials are crushed directly, Fine materials are extruded to form a material bed for inter particle crushing. The crushed materials continue to move to the edge of the grinding plate until they are taken away by the strong air flow at the air ring. Among the materials taken up by the air flow, the larger granular materials fall onto the grinding plate again under the action of their own gravity and continue to be crushed. The other materials enter the high-efficiency dynamic separator with the air flow for powder classification. Under the action of the blades of the high-efficiency dynamic separator, The materials that do not meet the fineness requirements return to the grinding plate for grinding, and the materials that meet the fineness requirements flow through the pipeline with the gas to enter the pulse dust collector for collection, and the finished powder is discharged through the discharge device. When the iron block and other difficult grinding sundries mixed with materials in the main machine move to the edge of the grinding plate with the materials, they cannot be blown up by the wind due to their large weight, fall into the lower cavity of the mill, and are scraped into the slag discharge port by the scraper installed at the bottom of the grinding plate, and then discharged out of the main machine.
