Production Site

A grand ceremony is held in Ningbo on April 27, 2017! The production line of 1.5 million tons of composite powder of Ningbo Ziheng, Shanghai Baosteel which is contracted by CHAENG(Great Wall Machinery Co.,Ltd) was put into production successfully.

Significance of the project

In order to study the recycling of steel slag, slag and waste from steel factory and solve the problem of steel mills zero emissions, Shanghai baosteel build this demonstration project of comprehensive utilization of steel slag composite powder in domestic. This plays a leading role for the comprehensive utilization of steel slag , solves the secondary effects on the environment of steel mill solid waste, and improves the efficiency of the enterprise.

Operation Status

It is reported that the first phase of the production line will use the GRMS46.41 steel slag grinding plant and 3.2 x 13 m steel slag ball mill from Great Wall machinery Co.,Ltd as the project's main grinding process which has high production efficiency and obvious effects in environmental protection and energy saving.

Before the deadline, the production of slag powder reached 110t/h , with the square meters of 454m squared/kg per kilogram, and the production of steel slag powder is 40 t/h, with the square meters of 500 m squared/kg in the Shanghai baosteel project. It runs well, each index is normal, and fully meet the customer's production requirements. As CHAENG(Great Wall Machinery Co.,Ltd) chairman Wang Jizhong had said, "CHAENG(Great Wall Machinery Co.,Ltd) gives the users the quality, credibility and trust."Shanghai baosteel officials said they will continue to carry out more far-reaching cooperation withCHAENG(Great Wall Machinery Co.,Ltd).

Equipment Process

Process flow of slag production line

Piles of slag are taken and fed by the forklift truck, and conveyed by a belt machine.In the process of conveying, slag raw material is iron-removing and screening through iron remover and vibrating screen, and then go into the vertical grinding machine for grinding by weighing equipment warehouse and elevator. The slag after milling is selected and dried by powder concentrator with hot air provided by the hot blast furnace.The slag powders that meet the fitness requirements are then sent to the dust collector to be collected and released, and lastly conveyed and stored in the library by the air trough and hoisting machine.

Main Equipment

The main engine of the project is the GRMS46.41 slag vertical roller mill and the 3.2 x 13m steel slag ball mill by CHAENG(Great Wall Machinery Co.,Ltd) .

1. Slag vertical roller mill

CHAENG(Great Wall Machinery Co.,Ltd) Vertical roller mill can meet the production line project of 20 ~ 1.5 million tons.We have received high praise from more than 90 customers, making CHAENG(Great Wall Machinery Co.,Ltd) an important part of the core technology of the industry. CHAENG(Great Wall Machinery Co.,Ltd) has been carrying out the ambitious goal of "the inheritors and the developer of the vertical roller mill".

1. Obtain the "double slipper ball mill" practical new patent certificate

2. The process is simple and the maintenance cost is extremely low

3. Reduce energy consumption by 30% and increase the amount of processing by 15-20%

4. The product rate is high, the operation is more stable

Process highlights

The hot blast furnace of this production line adopts the blast furnace gas discharged from the steel mill.Blast furnace gas has the features of strong toxicity, low calorific value, and mostly released into the air, so the recycling of blast furnace gas of this mine line minimizes the pollution to the surrounding environment,also dispense the high environmental taxes.The recycle of blast furnace gas can realize the double benefit of economy and environment.
