Modern sinter plants were developed in 1906 by Arthur S. Dwight and Richard L. Lloyd, and a chain grate strand type sinter machine which was able to operate continuously had been put into operation at Birdboro, Pennsylvania, USA, in 1911 (Vegman et al. 2004).The sintering process gained popularity quickly around the 1950s as …

Vibrating Feeders: How They Work and Effectiveness. Newton's First Law is the backbone of vibratory feeders. Contingent on the laws of physics, an object must first be in motion to stay in motion. A vibratory feeder is an instrument that uses vibration to feed material through a process or a machine while controlling the rate of flow.
Pellet bed heights up to 550 mm can be realized. The CSP Sinter Car for sintering is used to air-sweep ore fines and sintering concentrates through the charge layer during sintering belt movement. The car consists of a split or one-piece cast steel body, steel sealing plates, and lattice grate.
Basic sintering technology . The sintering technology is basically an agglomeration process for the iron ore fines which is dependent on heat to melt the surface of the smaller particles together to form larger agglomerates. A typical sinter plant consists of a number of sequential operating units with the sinter machine at the heart of the plant.
In producing feed for a lead blast furnace, concentrates analyzing 70 to 80 pct Pb are sintered to produce a physically acceptable low-sulfur product which contains only about 50 pct Pb.
direct smelting process for lead concentrates. T he lead blast furnace in tandem with a sintering machine has been the mainstay of the lead smelt ing industry for over fifty years. In 1970 it accounted for just over 80% of world lead bullion production. 1 Its nearest competitor, the Imperial Smelting Fur nace, accounted for 8%.
Fig 1 Flowsheet of sintering process. The iron ore fines are natural ore of size 0 mm to 10 mm. The raw mix (also called sinter mix) is made with the weighed amount of iron ore fines, limestone, dolomite, sand or quartzite fines (flux), solid fuel (coke breeze or anthracite) and metallurgical wastes (collected dusts, sludge and mill scale etc).
The sintering process begins with preparation of a sinter mixture consisting of iron ore fines, fluxes, solid fuel (called bonding agents in Japan) such as coke breeze, and return fines from the sinter plant as well as recycled ferruginous materials from downstream iron and steelmaking processes.

Figure 1 shows a simplified diagram of a sinter plant. Materials enter the sinter plant from storage bins. They are mixed in the correct proportions using weigh hoppers, one per storage bin, except for the return fines for which an impact meter is used instead. Weighing is continuous, as is the whole sintering process.

This reduces off-gas volumes by about 40–50% without affecting the sintering process. In an emission optimized sintering plant, the whole sintering gases are collected and then forced to recirculate on the sintering surface to contribute to the material heating (Fig. 3.18). In this way <50% of the waste gas is emitted in the atmosphere.
Poor permeability and low sintering productivity restrict the development of high-bed sintering. An efficient method of the double-layer sintering process (DLSP) was proposed to achieve high-bed sintering and solve the aforementioned problems. Theoretical calculation and sintering pot experiments were implemented to investigate …

During the process of sintering, heat is supplied by coke breeze in the sinter mix to increase the bed temperature to achieve partial fusion and diffusion bonding. Air flow rate and flame front speed in sintering process has been found to guide the performance of the sinter plant and these parameters mainly depends on the sinter bed permeability.
