GGBS plant

Introduction

As a new type of high performance concrete admixture, ground granulated blast furnace slag (GGBFS) has all kinds of performance advantages about improving concrete compressive resistance, tensile resistance, sheared resistance and bended resistance. At present, with the same amount of GGBFS instead of concrete and cement product of cement dosage, which has become the main trend of building materials industry. Great Wall Machinery is a professional supplier of GGBFS production line, provide "turnkey" service from civil engineering to debugging and capacity and standard reaching to customers, let customers put into production of GGBFS with saving worry, saving effort and high-efficiency.

1. Magnetic Separator

A magnetic separator creates strong magnetic attractions with ferrous materials. It is commonly used to remove unwanted iron contaminants from cement mixtures as they are conveyed on a belt conveyor to the crusher and grinding mill. Separating iron from mixtures avoids the risk of long, big iron parts tearing open the conveyor belt, ensures the proper functioning of the crusher and grinder, and improves the grade of raw material. In addition, recovering ferrous metals from raw materials also comes with financial benefits.

Our permanent magnet separator for pipeline is an automatic high-performing magnetic separation device. It is often utilized in cement, electricity, ceramics, bricks and tiles, chemical engineering, food, glass, metallurgy, and steel industries, as a separator of choice when it comes to purifying materials and ensuring the operational safety of the downstream equipment on the production line.

2. Dust Collector

Air-borne powder enters the rotary separator at its bottom, where guide vanes force the air to change from an upward flow to a tangential flow. The separator rotor tends to rotate along with the air flow without causing any drag to the stream. Hence, a centrifugal zone is formed between the guide vanes and separator vanes, where powder is separated from air.

During separation, larger particles are thrown outward by rotary force of the separator rotor, falling to the bottom of separator due to the force of gravity. After exiting the centrifugal zone, these oversize particles are collected in a conical hopper and returned to the grinding roller mill. Finer particles are brought through the center of the separator chamber and out the top, where they are collected by a dust collector.

3. Central Control System

The central control system is a critical part of the production line. It is comprised of the Distributed Control System, and the Closed-Circuit Television which contains 6 monitor circuits.

In a distributed control system, or DCS for short, there are a number of computers, each controlling a separate circuit. Information from each computer can be collected together and obtained by the central controller, which facilitates centralized management and control. Compared with the computer controlled multilevel system, DCS has the advantages of optimized, flexible layout, low cost, high reliability, maximum accessibility, great flexibility, easy maintenance, good compatibility, and comprehensive functionalities.
