Comparison of Sintering Mixed Granulation Processes

2022-02-11

The mixing and granulation process is a very important part in the sintering production process. Mixing is to carefully mix the components in the batching process, and granulation is to make the material into a mixture with suitable particle size and good air permeability.

Forming test of briquette containing carbon pellets

2022-01-28

As the main raw material for direct reduction of rotary hearth furnace, the cold consolidated carbon briqued coal needs to go through transportation, distribution, reduction, discharge and other processes in the production process of rotary hearth furnace, so its performance in all aspects affects the smooth production and efficiency of rotary hearth furnace. In this paper, syrup was used as binder, vanadium titanium magnetite and pulverized coal were used as raw materials to study the influence of different binder ratio, forming pressure and water content on the cold consolidation performance of carbon pellet.

Manganese fine ore is treated by briquette method

2022-01-28

Manganese powder ore generally refers to fine-grained concentrates obtained by beneficiation, and fine-grained materials containing manganese such as soot and ash obtained from smelting manganese ferroalloys in blast furnaces and electric furnaces. The briquette method is one of the manganese powder ore agglomeration methods.

Application of paper pulp waste liquid binder

Pulp waste liquid is a good binder in the cold consolidation briquette industry, because of its low price, there are industrial cases instead of molasses as binder applications.

Molasses binder

2022-01-18

1. Molasses standard（Adapted from" QB/T2684-2005) 1.1、Sensory requirements Dark brown color, viscous liquid, no odor 1.2、Quality requirements are shown in Table 1 Table 1 project Indicators Total sugar (sucrose fraction + reduced sugar)/% ≥ 48.0 Purity (total sugar/refraction hammer) /% ≥ 60.0 Acidity ≤ 15 Total ash (sulfuric acid ash) /% ≤ 12.0 Copper (in Cu) (mg/kg) ≤ 10.0 Total number of colonies/(CFU /g) ≤ 5.0x105 Note: if the total reducing sugar, purity is lower than the above index value and the acidity, total ash and total bacterial colony are higher than the above index value, if the buyer and the seller still want to trade, they can formulate a detailed contract and calculate the price according to the quality. 2. Ingredient list of sugarcane molasses from a sugar factory project Indicators The moisture 20% Total sugar 46-52 sucrose 28-32 Reducing sugar 18-20 Non-fermentative sugars 2-4 non-sugar organic compounds 9-12 Soluble gums and other carbohydrates 4 Aconitic acid 3 Citric acid, malic acid, succinic acid, etc A small amount of Wax, sterols, pigments, vitamins A small amount of Protein (Nx6.25 2-3 Sulphated ash 10-15 Na 0.1-0.4 K 1.5-5.0 Ca 0.4-0.8 Cl 0.7-3.0 P 0.6-2.0 PH 5.2-5.7 The molasses collected all the non-sugar substances that could not be removed by the clarification of sugarcane juice and the non-soluble sugar added in the sugar-making process, as well as various degradation products and new coloring substances. It is estimated that 0.455 parts of non-sugar water per part of waste sugar cane honey is needed to remain dissolved, while approximately 1.8 parts of sucrose is dissolved per part of water. Thus, for each non-sugar part of the waste honey, about 0.82 parts of sucrose are dissolved and cannot crystallize. 3. Knowledge about molasses 3.1 For cold consolidated briquette, molasses can be used as a binder alone, and some may need to be diluted during use, and a certain temperature is required. Molasses can also be used together with other materials as a binder. For some briquette which needs special use, molasses may also be used as the main raw material to add other materials to prepare a binder with composite properties. 3.2 Dilution method of molasses 3.2.1. Intermittent dilution method Intermittent dilution of molasses takes place in a dilution tank with a stirrer and usually requires some heating and insulation Basic method: the molasses is pumped into the high tank, weighed by the scale, and then poured into the dilution tank. At the same time, a certain amount of water is added, and the blender is used to mix thoroughly to obtain the desired concentration of sugar liquid. 3.2.2．Continuous dilution method （1）Continuous without agitator diluter, the diluter for a cylindrical tube, and along the tube length is equipped with a number of hole plate baffle plate and a sieve plate, in order to make the molasses mixed with water better, each hole location on the board is staggered arrangement, that is, a hole on the top, one on the bottom, this is liquid in the process of flow, turbulent motion, better molasses mixed with water. （2）The use of vertical cylindrical tubes with varying cross-sectional areas is still aimed at ensuring good mixing of molasses and water 3.2.3. Diluting molasses is how the amount of water added is calculated In order to prepare a certain concentration of diluted molasses, it is necessary to accurately calculate the amount of water and molasses required, which can be calculated by the following formula. P.c=V.d.c1 P----- Amount of molasses（kg） c----- Molasses concentration （Bx） v------ The volume of the diluted sugar solution（m³） d------- Density of diluent kg/m³ c1------ Concentration of diluent（Bx） The amount of molasses required P=V.d.c1 /c The amount of water to be added to diluent is w, w= V.d-p because：V.d= P.c/c1 w= P.c/c1-p= P(c-c1)/c1 Note: certain mildew inhibitor can be added when diluting molasses to improve its shelf life.

Application of Molasses in Powder Ore Metallurgical Briquetting

2022-01-05

When smelting carbon ferrochrome and silicon-manganese alloy, due to there is a lot of fine ore in the ore, the air permeability of burden becomes worse and the furnace condition deteriorates, which leads to the increase of power consumption and the difficulty of recovering gas in the closed furnace. Therefore, energy utilization, economic benefits, and environmental protection are affected. Avoiding fine ore entering the furnace has become an important part of factory smelting.

Coal-based Direct Reduction Rotary Hearth Furnace Process (1)

2022-01-05

Rotary hearth furnace technology is the world's first rotary hearth furnace with production scale, which was developed and built in the United States in 1978 by the International Metal Company affiliated to INCO Group of Canada in order to treat and utilize metallurgical wastes. It can not only be used to treat dust produced by metallurgical plants and other wastes containing iron, chromium， and zinc, but also be used to reduce iron ore.
