The tunnel kiln process is relatively simple, the technical content is low, and the raw materials, reducing agents, and fuels are easy to solve. The process has strong practicability, small early investment, and is suitable for small-scale production. It is a metallurgical reduction production process commonly used in the powder metallurgy industry.

Gas-based direct reduction iron (DRI), which has been commercialized, is made from natural gas or coal. In recent years, with the global attention to carbon dioxide emissions, active research has been carried out on the low carbonization of DRI processes, mainly carbon dioxide removal in existing commercial DRI processes or the use of renewable energy to produce reducing gas.

SSC800 classification crusher consists of: 1. frame, 2.motor, 3.torque-limited hydraulic coupling, 4.reducer, 5.coupling, 6.bearing seat, 7.side plate, 8.crushing roller, 9.ubricating oil pump and 10.traveling mechanism.

Solid preparations of solid beverages, health food and drugs all need to mix the components of solid powder. The proportion of components in the formula can reach 80%-90%, and the proportion of components is less than 1%. The forms are powdery, granular and flaky.

The production of calcium magnesium phosphate fertilizer by blast furnace method has certain requirements on the particle size of phosphate rock and flux entering the furnace. Screening off fine ore less than 10mm is one of the important prerequisites for smooth operation, high yield, stable yield and low consumption of blast furnace. However, at present, the content of fine ore in the raw phosphate ore is as high as 20-40%, so the treatment of fine ore has become an urgent problem to be solved in the current phosphate fertilizer plant.

HPS mixed pellet sintering belongs to the small pellet sintering process, which is to mix iron ore powder, returned ore, flux and fuel with water to make small balls with a diameter of 5-10mm, wrap a certain proportion of solid fuel on the surface of the small balls, and then sinter. Compared with the common sintering method, the small pellet sintering method has increased the process links of strengthening granulation and rolling pulverized coal outward.

Mixed granulation process is a very important link in sintering production process. High intensity mixing is to mix all kinds of materials in the batching process evenly. Granulation is to make materials into mixed materials with appropriate particle size and good air permeability.

Nibrasco briquetting plant was completed and put into production in August 1978. This article will describe the process flow of each section of the factory.

This article talks about the material and binder selection, equipment, testing method of sponge iron power. The proper parameters are discussed in this paper.

We are talking about high pressure briquette machine here with its stress features, but also the issues cause bearing windage and solutions for it.
