Introduction to the processing technology system of the jaw crusher production line

Jaw crushers usually do not work independently, but together with cone crushers, impact crushers, sand making machines, vibrating screens, etc., constitute a complete set of sand and gravel processing systems to achieve accurate processing of ore and rock and improve product pertinence , Increase its market value. Common production lines are: stone production line and sand production line.

Sand production line

Sand production line processing technologye

On the basis of the stone production line, sand making machine equipment for fine crushing and shaping is added, which can realize the simultaneous production of machine-made sand and crushed stone. The entire production line is flexible in construction and diverse in output, which can meet the various processing requirements of customers. , To achieve the purpose of "one line with multiple uses", it is an ideal production line choice for producing highway surface materials, high-speed railway sand and gravel aggregates, hydropower station sand and gravel materials, port terminals and airport runways.

Desulfuration Behavior of Low-grade Iron Ore-coal ...

The process of coal-based direct reduction followed by magnetic separation was employed to produce direct reduction iron powder (DRIP) from a refractory low-grade iron ore. The desulfuration behavior of the composite briquettes during this process was studied. Experimental results showed that this process presents advanced sulfur removal ability.

Sticking mechanism of low grade iron ore-coal composite

2018-11-1  The iron ore with a low iron grade but high SiO 2 was obtained from Qidong area (Hunan, China). As shown in Table 1, the total iron content (T.Fe) was 33.86 wt%, while the content of SiO 2 was 40.61 wt%. Other constitutes included 4.36 wt% Al 2 O 3, 1.57 wt% of CaO, and 1.05 wt% of MgO.XRD pattern shows that hematite, quartz, chlorite and sericite constituted the main phases of this ore.

Reduction Enhancement Mechanisms of a Low-Grade Iron

2017-11-1  The reduction behavior of a low iron grade with high SiO2 content ore–coal composite was investigated in the temperature range of 1143 K to 1263 K (870 °C to 990 °C). Sodium chloride was chosen as an additive to promote this reduction process. The effect of the sodium chloride addition and its mechanism was also investigated. Results showed that the added sodium chloride could enhance

Integrated Pyrolysis–Tar Decomposition over Low-Grade

2017-2-3  A combination of coal and biomass (coal–biomass co-pyrolysis) provides an advantageous synergetic effect to overcome the disadvantage of using renewable raw materials, such as biomass. In this study, we investigated the effect of coal–biomass co-pyrolysis in integrated pyrolysis–tar decomposition over low-grade iron ore. Combined coal ...
