CRLM Coarse Powder Vertical Mill

CRLM Coarse Powder Vertical Mill Information Introduction

The CRLM Coarse Powder Vertical Mill is a heavy-duty grinding equipment designed by Cronus Machinery to process materials with large particle sizes (≤120mm), high moisture content (≤25%), and complex compositions. Through an integrated "crushing-drying-grinding-classifying" process, it efficiently converts bulk raw materials into uniform coarse powder in a single flow. It is the core equipment for large-scale industrial continuous production in fields such as cement raw meal, industrial solid waste, and metallurgical sintering.

CRLM Coarse Powder Vertical Mill Features & Advantages

The Coarse Powder Vertical Mill consists of grinding, static classification, drying, transmission, and hydraulic systems. With a vertical roller mill structure, heavy-duty wear-resistant design, robust grinding rollers and table, and a powerful drying system, it can directly process materials with large particle sizes, high moisture, and complex compositions.

Structural Features

Grinding System: Composed of wear-resistant reinforced grinding table, rollers, and heavy-duty pressurization device. Utilizes material bed grinding principle.

Classification System: Static classification system, relying on fixed guide vanes and blades to generate a centrifugal force field for separation. Reliable operation, not prone to clogging.

Drying System: Enhanced heating capacity of the hot air furnace, high air volume and pressure, effectively optimizing airflow distribution and improving efficiency.

Transmission System: Composed of a high-power main motor and heavy-duty reducer, ensuring stable operation of the coarse powder vertical mill under high load conditions.

Hydraulic System: The hydraulic station provides immense grinding force through roller pressurizing cylinders, independent maintenance hydraulic cylinders facilitate equipment start-up and maintenance.

Performance Advantages

Strong Adaptability: Wide range of applications; large feed particle size (≤120mm) allows direct processing of materials with complex compositions.

Robust & Durable: Heavy-duty wear-resistant design, sturdy structure, strong impact resistance.

Non-Clogging: Simple and reliable classification system effectively reduces material clogging and wear issues.

Powerful Drying: Built-in powerful drying system, capable of directly processing wet, sticky materials with high moisture content (≤25%).

High Efficiency & Energy Saving: Energy utilization rate higher than ball mills, energy consumption reduced by 30%~40% when processing the same material.

CRLM Coarse Powder Vertical Mill Process Flow

Raw Material → Coarse Powder Vertical Mill → Material Bed Grinding → Simultaneous Drying → Pneumatic Lifting → Static Classification → Coarse Powder → Dust Collector → Finished Product Packaging

Feeding & Material Bed Grinding

Raw materials meeting feed requirements (particle size ≤120mm, moisture ≤25%) are conveyed into the coarse powder vertical mill. The transmission system drives the grinding table to rotate, and the material spreads under the rollers by centrifugal force. The rollers crush the material bed under the pressure of the hydraulic system.

Powerful Drying & Pneumatic Lifting

High-temperature hot air introduced from the bottom passes through the material layer, instantly evaporating moisture during crushing. The dried material fragments are carried upward by the high-speed rising airflow.

Static Classification & Internal Recirculation

The material enters the static classification system with the airflow. By adjusting the guiding device, separation is achieved using inertial and centrifugal forces. Coarse powder meeting particle size requirements enters the collection system with the airflow, while oversized particles are separated and fall back to the grinding table for regrinding. This internal circulation enables the production of coarse powder ranging from 40 to 325 mesh.

Finished Product Collection & Exhaust Gas Treatment

Qualified coarse powder enters the single-stage dust collection system (using electrostatic precipitator or bag filter) with the airflow. The simplified process reduces resistance, effectively saving fan energy consumption. After gas-solid separation, the finished coarse powder is collected, and the purified gas is discharged by the exhaust fan.

Frequently Asked Questions About Coarse Powder Vertical Mill

What is the difference between a Coarse Powder Vertical Mill and a standard vertical mill?

The Coarse Powder Vertical Mill is mainly used for the production of coarse powder with low fineness requirements, while the standard vertical mill is primarily used for producing fine powder with uniform fineness and high added value.

Is the classification system of the Coarse Powder Vertical Mill dynamic or static?

The Coarse Powder Vertical Mill typically adopts a static or inertial classification system. This design features a simple structure, high throughput, wear resistance, and is not prone to clogging.

How to handle clogging in the Coarse Powder Vertical Mill?

The Coarse Powder Vertical Mill is equipped with inspection doors and cleaning ports. In case of clogging, cleaning can be performed through the cleaning port. Routine maintenance requires regular inspection of material accumulation on the grinding table and in the air duct.
