    The crushing equipment adopts hammer double-rotor impact crusher and the product structure is developing for the fine crushing. The development of high-new equipment requires plentiful functional materials and the application of modern fine crushing technology has become an important symbol of embodying the national technology level. Dry sampling is basically used whenever materials cannot be dissolved in solution, or when they are inappropriate to melt either because of their structure, or because of the cost associated with melting vs the possible return. As it is difficult to achieve homogeneity, dry sampling is tedious and complex. Most spent hydrocarbon process catalysts are sampled with this method. As previously mentioned, spent catalysts, when removed from a reactor, are often contaminated with organic materials that must be eliminated to ensure accurate evaluation of their remaining precious metals. These catalysts must first be processed to remove those contaminants to provide free flowing properties, which ensures accurate sampling and permits safe and efficient operation of the electric arc furnace, ultimately recovering the remaining precious metals. The goal with all sampling procedures is to obtain material samples that represent entire lots of spent catalysts accurately. To that end, to continuous catalyst sampling system generates homogenous, consistent and reproducible intermediate samples, using a variety of equipment and techniques. For example, after preburning in the rotary kiln, two deck Sweco screen separates tramp or oversized material and purposes, which are subsequently reduced from catalyst pellets in a Knight automatic sampler, before progressing to the next process. This next step is critical also. Knight samplers dual generate bulk samples of 10% each, followed by another 10% of the remainder. This essentially creates two 1% of the total original lot samples. Our company produces four types of the classifier which are high weir single screw, double screw, submerged weir high single screw and double screw submerged. The classifier is widely used in the mineral beneficiation plant to work together with the Ball mill when forming the closed circuit recycling distributaries sands, or grading the sands and fineness in the gravity selection. The classifier also have the function of sorting the coexistence, desliming and so on. It is easy to control and with simple structure. The plant was built in 1975 and designed annual handling 60 million tons of manganese ore carbonation poor flotation plant. Flotation device flotation column processing plant has not been put into operation to meet the design requirements, in the experimental study, based on the 1985 cyclone off the mud Flotation.
