Grinding system technical reformation in nowadays

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) January 4, 2012 --

In cement industry,Hammer crusher grinding process technology of the whole factory for saving energy, improve the overall economic efficiency has a pivotal role. Our country's many cement enterprise still use old ball mill as cement grinding equipment, with these mill production out of the cement, there are generally small degree is not enough and size distribution is not reasonable, cement uniformity coefficient is bad, the low intensity of problems. After the implementation of the new standard cement, also reflects the comprehensive benefit of the decline of the problems, such as the time of production by mixing with material reduce, unable to produce the high standard cement, etc.
In recent years, along with the deepening of the theory and practice, people on how to improve the grinding system's production, quality of a lot of work, some enterprise from the ground to reduce material particle size, also have some enterprise from the classifier choose powder efficiency fluctuation etc.Vibrating grizzly feeder Taken together, these ideas are correct, but often cannot achieve satisfactory effect, the reason is not these problems systematic, and not the other equipment system, process parameters change, grinding system needs to be considering each factor.

Grinding system comprehensive reconstruction technique.

Ordinary grinding system problems: a, internal grinding machine: on the one hand the single diaphragms, just the ball will be forging and other ground body have simple isolation effect, makes a big part of a coarse particle into fine grinding warehouse, cause fine grinding warehouse function disorder, many manufacturers choose to use big norms grinding medium remedy so as to restrict the fine grinding performance of the storehouse,VSI sand maker affect production ability; On the other hand grinding material can not be qualified in the discharge, or unqualified material can't get effective control, have caused grinding phenomenon or system grinding worse.Ore vibrating feeder B, grinding the classifier: classifier as one of the important closed-circuit grinding auxiliary machine, its performance directly affect the output of grinding machine and the quality of the cement, many choose powder performance, select the powder precision is too low; Classifier specifications slants small, unilateral pursue choose powder efficiency. C, difficult to grinding specific surface area 320 m2 / kg quartile of cement, when grinding quartile 320 m2 / kg of surface area than cement, ordinary grinding material than not commonly inside the ball, coarse grinding warehouse the feed in the ball too than, fine particle more; Fine grinding materials storehouse less memory.
All factors,Mobile crushers grinding system comprehensive reconstruction technique, in the following several aspects of improvement:

(1), optimizing the structure in the grinding, the new screen space warehouse device, adjust the position, and fine grinding warehouse warehouse the activation device, strengthen the grinding medium 3 d activities to improve the grinding efficiency, the grinding device USES material forging a new separation held grinding deck plate,Mobile jaw crusher according to grinding machine speed and material properties of high-performance lining board again configuration to adjust the dynamic distribution and grinding body movement track, etc.;
(2), using the high performance classifier, improve its choose powder efficiency, control cement products particle gradation, with more mixed material. Can update or modification of classifier, to make it a high performance classifier;
(3), strengthen ventilated and grinding mill in the lock the wind;
(4), optimizing the steel ball mill gradation;
(5), clean grinding mill in environment, add in addition to iron craft;
(6)Impact crushing machine, and implementation of mill system testing and the process parameters are controlled;

(7), as low as possible into the ground material particle size.
Performance characteristics
(1) the optimization design innovation, comprehensive and integrated system process parameters, the grinding high yield and high efficiency in the grinding choose powder organically, efficient cement grinding of closed-circuit system, implement a system secondary choose powder;

(2) high grinding technology: closed-circuit type screen space efficient device, activation ring, storehouse discharging device and high yield lining board type use of science in the grinding, optimize the grinding medium dynamic distribution, make full use of grinding medium kinetic energy, improve the mill milling efficiency;
(3) efficient choose powder technology: high efficiency, high efficiency, high grade scattered low resistance cyclone dust collecting, thick powder cleaning technology, performance testing technology, organic combination, choose powder performance and product makings composition greatly improve;
(4) of high-yield, high-quality effect: the system technology in open flow grinding can be increased production based on 60-100%, based on closed-circuit mill in improving 30-50%, specific surface area increased by more than 15%;

(5) convenient adjustment: cement surface area than in 300-400 m2 / kg to arbitrarily regulate, and overcome the closed-circuit grinding surface area than the low cement traditional defects, more relevant to ISO standards;
(6) system steel consumption less: using this system steel consumption greatly reduced, tons of cement consumption reduce 20-30%. The technology is adapt to open flow mill modification, and adapt to the closed-circuit cement mill modification.
