Problems Mill Work And Renovation

Ball mill in the chemical industry, metallurgy, building materials, power generation, ore mining and other fields have a wide range of applications, due to the structure and control characteristics of ball mill, SCM Ultrafine Mill so that the high energy consumption. In order to improve production efficiency ball mill, reduce energy consumption, the need for fully automatic control of the ball mill design. Cyclone dust collector system from grinding to a ball mill feed end of the large height difference, inertia and the whereabouts of the material feed chute refraction is likely to cause the phenomenon of red material. The refractive power of the larger material into the mill toward the diaphragm plate, the measurement from a bin liner grinding feed end position since less material within about 1.30m length, forming a grinding blind, equal a reduction of a warehouse grinding length, the actual length of a warehouse becomes effective 2.45m), reducing the work capacity of a warehouse grinding. Against the adverse conditions, combined with the actual size of the mill feed inlet, a feed chute to take measures in the front cover and side edges and bottom openings, etc., to maximize the ease of refraction material into the mill, the feed caused Outshoot grinding blind play of the impact grinding materials, grinding, improve grinding efficiency of a warehouse. After rectification of the feed substantially eliminated red material, refraction caused by a grinding compartment blind.

Solve grinding media and liner work surface adhesion of serious problems For diaphragm plate mill, the zeolite powder vertical mill grate plate plugging problems, the transformation process, the installation attempts to prevent wear composite diaphragm plate, wear attempts to prevent the type of self-cleaning of the grate plate mill, as well as material, air separation plant evenly, completely solve the diaphragm plate and the plate mill grate clogged, so always maintain good ventilation inside the mill, over-feeding capacity by the end of the grinding mill and the dust collection fan heat and water discharged in time to promote the ball subsystem virtuous circle. In order to maintain the grinding body and lining work surface finish and stabilize the grinding efficiency, the effective elimination of adhesion, the production process, adding a 3.5 / 10000 liquid grinding aids. Grinding aids added, grinding material ground for significantly improved, while significantly improving the flow of materials within the mill to make the material easier to ground through the grinding compartment plate and grate seams, promptly discharged outside the mill. Aids increases the material in the separator in the dispersion, is extremely beneficial to the grading process, and can be increased by more than separator efficiency 2% to 3%.

Improved grinding mill in each bin grading

Improved front, two positions ball, mixed segment, the improved, two positions grinding steel balls used in all small, increase grinding capacity, the total load of the LUM Ultrafine Vertical Roller Mill to 240t. Above, mainly from the grinding mill blind, diaphragm plate and the plate mill grate clogged mill warehouse body transformation, grinding media and liner serious adhesion problems, grading grinding mill and other aspects of the problem may be encountered in the analysis and solving . Different types of mill equipment there will be more questions, if in doubt, please consult us.

Mill automatic control system uses a hierarchical structure, from the lower mill automatic control system to the upper layer is divided into: signal detection, control the lower, upper control and management of three important parts. Each layer laterally diverging be expanded so that the ball has very good scalability, data exchange between the layers via a data network to construct a good organic whole, so as to effectively improve ball control safety and reliability sex. Wherein the detection part of ball control system comprising: a variety of analog or digital sensors and transmitters, various measurement field signal for when the mill work. Lower control link mainly includes: control station and signal station. The main control station in which the data processing and communication exchange with the host computer and the signal station. For each input signal station to achieve acquisition and pre-processing of the signal and the control signal output. Divided into upper control station operator station and mill operation system monitoring station, completed the overall control system configuration and mill automatic control system real-time monitoring.
