Control of the technical indicators mainly refers to the observed changes, and then we can adjust the foam respective process conditions. Therefore during the operation, we need to always pay attention to the foam flotation changes (so-called look bubble adjustment). What kind of foam is preferably, depending on the ore, fumble through the period of the production practice. In general, bubble size uniformity better mineralization (taking a dip with a multi – mine), very clean (and feel) to single color, scrapings seem heavy rustle, beneficiation indicator at this time is better. Factory but should be combined with the specific circumstances of the best indicators of experience summed up what kind of foam. We need to check whether the process ministries industry normal work and job workload distribution is appropriate, job efficiency and product indicators and the nature of the problem, it is necessary to carry out the processes visitas.
By examining further adjust reasonable combination for each job, to find out the problem of the job, try to solve the beneficiation process to further improve the technical and economic indicators. Therefore, the process investigated is sometimes a regular basis, sometimes according to production problems at any time, and sometimes the whole process of investigation, sometimes local process (a period of) visits. The survey is intended to decide. The crusher is widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry and many other sectors. Common crushing machines are winnowing mill, hammer crusher, impact crusher, roll crusher, crusher compound. Jaw crusher (jaw crusher), having large crushing ratio, uniform particle size, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics. PF-I series impact crusher can process materials side length is 100 to 500 mm, the compressive strength is up to 350 MPa, great crushing ratio, cubic particles advantages of material was broken; PF-II series impact crusher machine, suitable for crushing hard materials, such as cement crusher, with a production capacity of the material advantages of small particle size.
The main operation of the process are the investigated sampling and sample handling, preparation from two aspects, first, determine the number of sampling points and sampling, to be marked in the process of sampling points and the sampling method. The other is ready to sampling tools and mining equipment container. For example, the broken the miners segments of visits, sampling point election in the transport belt. This section of the ore are dry, and larger particle size, so that tools necessary to bigger, weighing general also have scales.
