Micronizing plant

उत्पाद विवरण

1. Introduction

A Micronizing Plant is an advanced industrial system designed for ultra-fine grinding and particle size reduction of a wide range of minerals and materials. The process involves reducing raw material feed into fine powder form with controlled particle sizestypically ranging from 1 micron to 100 micronsdepending on the application requirements.

At KINC Mineral Technologies Pvt. Ltd., we specialize in the design, engineering, manufacturing, and commissioning of customized micronizing systems for minerals such as calcite, dolomite, quartz, barytes, talc, kaolin, bentonite, feldspar, silica, and other industrial minerals. Our plants are engineered for high efficiency, consistent product quality, low energy consumption, and minimal maintenance.

2. Process Description

The Micronizing Process typically involves the following major stages:

a. Feed Preparation & Handling Raw material is crushed to a manageable size (typically <10 mm). Material is fed into the system through a feed hopper and screw feeder for uniform dosing into the mill.The feeding rate is controlled to maintain optimal mill load and grinding efficiency.

b. Grinding / Micronizing Section

The core of the plant is the Ball Mill or Jet Mill (depending on application and product fineness requirement). In the Ball Mill system, grinding occurs by impact and attrition between the balls and the material inside a rotating drum. In Jet Mills, micronization is achieved through high-velocity air or steam jets that create intense particle collisions. Grinding media and liners are selected based on product hardness and contamination sensitivity (e.g., Alumina, Ceramic, or Steel).

c. Air Classification / Separation

The ground material is conveyed pneumatically to a High Efficiency 

Air Classifier.

The classifier separates fine particles from coarse ones using centrifugal and drag forces. Fine particles meeting the required size are collected as final product, while coarse particles are returned to the mill for further grinding (closed-circuit operation).

d. Product Collection

Fine powder is collected through Cyclone Separators and Pulse Jet Bag Filters. A Blower / Fan system maintains the required airflow and pressure balance. The collected product is discharged through rotary airlocks into storage bins or packing systems.

e. Control System

Fully automatic PLC-based control panels monitor parameters like feed rate, air pressure, mill speed, and classifier RPM.

Data logging and safety interlocks ensure consistent performance and operational reliability.
