time dressing experiment research purposes is divided into the optional tests, process tests and beneficiation single test three, divided into laboratory tests, pilot scale i-industrial tests and industrial test three.In order to facilitate a clear beneficiation test requirements and facilitate the description, summarize the above two categories,cone crusher type of dressing experiment as an optional test, the small flow test laboratory, the laboratory Continuous Test, i-industrial tests, industrial test and individual test six kinds.An optional test: usually completed by the Geological Survey department.Geological Survey, Chukan and detailed survey stage, the gradual increase and deepen the depth of the optional test.Optional test focuses on research and explore the nature of various types and grades of ore with an optional difference, basic beneficiation beneficiation indicators may reach harmful impurities removed the difficulty associated ingredients comprehensive recycling possibilities.Content and depth of the pilot study should be able to determine the use of the Ore exploration is feasible technically, whether it is economically reasonable to provide a basis for the development of industrial indicators and deposit evaluation.Optional test is conducted in the laboratory device or on small devices, generally use for deposit evaluation.2 small processes of the laboratory test: the small processes of the laboratory test is after the completion of the deposits in geological exploration,[rock crusher:http://www.xb-machine.com] feasibility study or preliminary design before.It focuses on the characteristics of the ore minerals and beneficiation process characteristics, the processing method, the process structure, processing indicators, process conditions and product (including some of the intermediate products), testing and analysis, and should test comparison of two or more programs.Content and depth of the pilot study, generally should be able to meet the initial design work for the development of process and product solutions, select the main process equipment and design requirements.
The small scale of the small process of laboratory specimen, flexibility, cost, human and material resources, thus allowing a greater range of extensive exploration,[jaw crusher:http://www.china-xingbang.com] because the specimen is easy to mix, easy to control batch operating conditions.Therefore, the most basic test of the test.However, it is in the laboratory a small non-continuous (or continuous partial) test equipment, alicey599 simulate the extent and reliability of test results better than an optional test, but less than the laboratory scale continuous test.Laboratory Continuous Test: Continuous Test laboratory is a continuous test after the completion of the small flow test, according to small-scale process testing to determine the process, using test equipment simulating the industrial production process of grinding,jaw crusher sorting as well as dewatering operations.It focuses on the inspection process dynamic equilibrium conditions (including middlings return) beneficiation indicators and process conditions.Trials research unit for the ability of the test equipment is very inconsistent, generally 40-200 kg / hour.Laboratory to expand the analog of the continuous test than the small-scale process test, higher reliability of the smaller flow test.4, semi-industrial test: i-industrial tests carried out in purpose-built i-industrial pilot plant or workshop, the test can be continuous,[Mobile Crusher:http://www.xb-machine.com/Crushing_Machinery/Mobile-Crusher.html] the whole process can also be a semi-industrial tests of the local operations of continuous or single.The test's main purpose is to verify the process of laboratory testing program, and has made similar to the production of technical and economic indicators to provide a reliable basis for the concentrator design or lay a foundation under further as industrial test.Semi-industrial test equipment used for small-scale industrial equipment, rules and regulations of the pilot plant is no clearly defined, generally 1-5 t / h.
