In the cement productionprocess, the grinding (cement and slag) power consumption accountedfor Integrated Product power consumption over 60%, especially theslag powder 400m2/kg than in the above table, the grinding powerconsumption remained at 90kwh / t more than hard slag cement millgrinding of a direct impact on the grinding capacity. At present, thegrinding process is still lagging behind many small and medium-sizeddomestic cement enterprises outstanding problems, the traditionalgrinding equipment for the effective utilization of energy is nothigh. Grinding using new technologies, new equipment and othermeasures to achieve quality has become a high yield, an effective wayof saving energy and reducing consumption. Sony EquipmentManufacturing Co., Ltd. Chengdu, the light of these research anddevelopment of high-performance roller pulverizer can not only solvethe above problem, but also has more bright spots.

Efficient roll pulverizer isfor all types of ores by rough grinding the design, can be used as acement raw material, clinker pre-grinding may also be preparedmaterials such as gravel, can also be used for mineral processing,chemical, coal, ceramics, metallurgy, the use of refractoriness andother industries. It features high output, energy saving, can controlthe feed volume, adjusting the ball gradation adjustment platenesting control with, such as yield and grinding fineness.

The principle of efficientroll pulverizer: the use of hollow shaft spiral mandatory feed,edge-side discharge of the nesting structure of the way to ensuresmooth flow of material into the mill to reduce the over-grindingphenomenon, so as to achieve lower energy consumption in the case ofto ensure that the purpose of production.

Materials into the hopperthrough, was admitted to the hollow shaft spiral tube feeding. Thespiral tube feeding high helical vane structure, will be mandatorymaterial feeding tube mill machines, materials in the inner cylindermassive ball broken under the impact of the flow of discharge mouth,the mouth with discharge grate width required lining the sieve slitpassing through the grate Products raphe discharge, collected fromthe collection hopper into the process equipment under. Hopper setthe top with exhaust air interface, sets equipped with dischargehopper at the bottom of the mouth, I can discharge directly into thefinished product is expected under the process, such as user requestsotherwise, lock valve can be installed here.

Than comparable products, andefficient roll pulverizer has the following advantages:

First, the design:

1, price: traditional rollpulverizer (Φ1.2 × 400) investment of 600 million (around includingconstruction). And efficient roll pulverizer (Φ2.6 × 3.7M)investment in the 145 ~ 150 million (including construction).

2, energy-saving:

(1) power: traditional rollpulverizer main motor has 280 × 2 = 560. Together with the auxiliarypower consumption as much as the total 650kwh; efficient rollpulverizer of total electricity consumption 280kwh.

(2) Efficient roll pulverizerto change the traditional model, the use of grease consumption isvery small.

3, the maintenance ofconvenience: The centers drive pulverizer, user-friendly day-to-daymaintenance of equipment. Bearings and the end of hollow shaftbearings are rolling bearings, which is similar to specificationssimilar to the ball mill production, compared to an installedcapacity of 18 ~ 25% lower, and save the water cooling system andreducing the consumption of lubricants.

Second, the use of

1, high output: the use ofhollow shaft spiral mandatory feed, edge-side discharge of thenesting structure of the way to ensure smooth flow of material intothe mill to reduce the over-grinding phenomenon, so as to achievesufficient production, energy conservation purposes.

2, the quality and stability:the stability of the expected size unchanged for a long time.
