In the cement production process, the grinding (cement and slag) power consumption accounted for Integrated Product power consumption over 60%, especially the slag powder 400m2/kg than in the above table, the grinding power consumption remained at 90kwh / t more than hard slag cement mill grinding of a direct impact on the grinding capacity. At present, the grinding process is still lagging behind many small and medium-sized domestic cement enterprises outstanding problems, the traditional grinding equipment for the effective utilization of energy is not high. Grinding using new technologies, new equipment and other measures to achieve quality has become a high yield, an effective way of saving energy and reducing consumption. Sony Equipment Manufacturing Co., Ltd. Chengdu, the light of these research and development of high-performance roller pulverizer can not only solve the above problem, but also has more bright spots.
Efficient roll pulverizer is for all types of ores by rough grinding the design, can be used as a cement raw material, clinker pre-grinding may also be prepared materials such as gravel, can also be used for mineral processing, chemical, coal, ceramics, metallurgy, the use of refractoriness and other industries. It features high output, energy saving, can control the feed volume, adjusting the ball gradation adjustment plate nesting control with, such as yield and grinding fineness.
The principle of efficient roll pulverizer: the use of hollow shaft spiral mandatory feed, edge-side discharge of the nesting structure of the way to ensure smooth flow of material into the mill to reduce the over-grinding phenomenon, so as to achieve lower energy consumption in the case of to ensure that the purpose of production.
Materials into the hopper through, was admitted to the hollow shaft spiral tube feeding. The spiral tube feeding high helical vane structure, will be mandatory material feeding tube mill machines, materials in the inner cylinder massive ball broken under the impact of the flow of discharge mouth, the mouth with discharge grate width required lining the sieve slit passing through the grate Products raphe discharge, collected from the collection hopper into the process equipment under. Hopper set the top with exhaust air interface, sets equipped with discharge hopper at the bottom of the mouth, I can discharge directly into the finished product is expected under the process, such as user requests otherwise, lock valve can be installed here.
Than comparable products, and efficient roll pulverizer has the following advantages:
First, the design:
1, price: traditional roll pulverizer (Φ1.2 × 400) investment of 600 million (around including construction). And efficient roll pulverizer (Φ2.6 × 3.7M) investment in the 145 ~ 150 million (including construction).
2, energy-saving:
(1) power: traditional roll pulverizer main motor has 280 × 2 = 560. Together with the auxiliary power consumption as much as the total 650kwh; efficient roll pulverizer of total electricity consumption 280kwh.
(2) Efficient roll pulverizer to change the traditional model, the use of grease consumption is very small.
3, the maintenance of convenience: The centers drive pulverizer, user-friendly day-to-day maintenance of equipment. Bearings and the end of hollow shaft bearings are rolling bearings, which is similar to specifications similar to the ball mill production, compared to an installed capacity of 18 ~ 25% lower, and save the water cooling system and reducing the consumption of lubricants.
Second, the use of
1, high output: the use of hollow shaft spiral mandatory feed, edge-side discharge of the nesting structure of the way to ensure smooth flow of material into the mill to reduce the over-grinding phenomenon, so as to achieve sufficient production, energy conservation purposes.
2, the quality and stability: the stability of the expected size unchanged for a long time.
