It is especially suitable for crushing limestone, medium hard stones and stones which compression strength are less than 200Mpa and calcium content is more than 40%.Our hammer crusher is mainly applied to stone crushing in construction industry, road and railway construction, house building and other industries that will use small stone materials.
It is widely applied to separate the particles into a number of products graded according to size in the complete closed loop together with ball mill in the mining industry, separate light particles from heavy particles in the gravity separation process, separate of fine particles and liquid from coarse particles in the metal ore dressing process, separate the slurry or liquid from solid particles in ore dressing plant. By combining the proper submergence of the spiral with one of the tank design a choice of 63 combinations is possible in straight, modified or full flare tank designs.Zenith's spiral classifier is designed to provide the most effective pool area and overflow velocity requirements. The proper combination of pool depth, area and spiral construction is important to secure a controlled turbulence in the slurry flow for accurate size separation.
3. The main hydraulic devices like pump, valve are imported from Japan. The use of all-walt variable hydraulic technique in the travel system ensures high performance, reliability and utilization of the motor. High pulling forge travel motor with mature techniques offers strong driving force and high reliability.
The coal discharge device of the tail beam-sliding plate was easily jammed and hard to slide. Because the sliding plate was not slid back, the sliding plate occasionally cut the chain of the rear scraper conveyor when the tail beam swung.
The experimental approaches are usually adopted to conduct some verifications for the analytical or numerical calculation methods. Kumar et al. Kim et al.  conducted the experiment to validate the theoretical analyses and FE results for the surface mounted permanent-magnet machine. Wang et al.  compared the analytical results with the experimental results based on the back electromotive force (EMF) which is obtained from the air-gap field distribution.  compared the back EMFs measured in the experiment with simulation results and verified the proposed FEM method.
These lower BCF values of Pb indicate a very low transfer of Pb in pea showing its least bioavailability in the BN 5%, FeHP 2% and CM 0.5% treatments showed the least BCF values of Pb, compared to the control. The results of a previous study have explained that Pb is early recognized as a toxic compound by the roots of plants and is vacuolated either in the cell wall or vacuole, which in turn leads to its low translocation to the aerial parts .5% amended soil, compared to control treatment . The BCF stands for the transport potential of Pb from the soil to the plant body, and is dependent on the characteristics of soils and Pb speciation .The TF and BCF values for Pb were significantly reduced with all amendments, compared to the control. The BN 5%, FeHP 2% and CM 0.5% (Table 1). The lower TF values of Pb are attributed to its accumulation in the cell membrane and vacuoles of the root, which is associated with the stable attribute of Pb in the soil-plant system . However, the least values of TF and BCF were observed after amending Pb-polluted soil with BN 5%, FeHP 2% and CM 0.
