Abstract
The invention discloses a double-roller press parallel grinding system which comprises two parallel roller press grinding systems, wherein each roller press grinding system comprises a roller press, a delivery pipeline, a classifying screener and a receiving system; a discharge hole of each roller press is connected with a feed inlet of each classifying screener by each delivery pipeline; two discharge holes are formed in each classifying screener; one discharge hole is communicated with a feed inlet of each roller press; and the other discharge hole is communicated with each receiving system. The double-roller press parallel grinding system is simple in process flow, convenient and reliable to operate, diversified in production mode, and flexible to allocate, makes full use of the characteristics of energy saving and consumption reduction of the roller press grinding systems, and completes crushing and grinding of materials, and the power consumption of the grinding system is reduced.
Description
Technical field
The present invention relates to a kind of building material industry and be used for the roller press grinding system that industrial brittle material is pulverized, the product of production is mainly granular material, relates in particular to a kind of double roll press grinding system in parallel.
Background technology
At present, be accompanied by the in recent years high speed development of Chinese national economy, China's cement production capacity in 2010 has reached 18.6 hundred million tons.New production line all is to produce the large-scale production line of 1,000,000 tons and above scale per year, and ton cement power consumption is about 90～100kWh, and the power consumption of grinding workshop section accounts for and produces 60～70% of cement power consumption, only cement grinding this, a year power consumption just reaches about 60,000,000,000 degree.
Roll squeezer applying high voltage bed of material pulverization principle, adopt single material to pulverize the working method of group feature, brittle material reduces rapidly the granularity of material through high-pressure extrusion (pressure of crush zone is about 150MPa), and all have a large amount of micro-cracks in the material of extruding, improved the grindability of material, make material in next operation during grinding, required energy consumption decrease.Use the cement grinding system with roller process of the pre-grinding of roll squeezer can increase production 50-200% than former traditional pure ball mill grinding system, the per unit area yield power consumption can reduce 20-40%, has saved the energy, has reduced the manufacture of cement electricity consumption, thereby realized sustainable development.Along with country proposes higher requirement to saving energy and reduce the cost, how under the prerequisite that guarantees product quality, further to improve capacity usage ratio, reduction grinding system power consumption, making larger contribution for the economic development of China becomes next step focus.
Summary of the invention
The object of the invention is exactly in order to remedy the defective of prior art, to provide a kind of quickly and easily double roll press grinding system in parallel.
The present invention is achieved by the following technical solutions:
A kind of double roll press grinding system in parallel, include two covers roller press grinding system in parallel, described roller press grinding system includes roll squeezer, conveyance conduit, classifying screen and material-receiving system, the discharging opening of described roll squeezer connects the charging aperture of described classifying screen by conveyance conduit, described classifying screen is provided with two discharging openings, a discharging opening is communicated with the charging aperture of roll squeezer, and another discharging opening is communicated with described material-receiving system.
The work of described roll squeezer, classifying screen and material-receiving system is the control of controlled system all.
Described material-receiving system includes collecting box and blower fan, and described blower fan is communicated with collecting box.
The outlet of the material-receiving system of the roller press grinding system that described two covers are in parallel all connects the charging aperture of ball mill, and the discharging opening of described ball mill is communicated with another material-receiving system, in conjunction with forming the combination grinding system.
Among the present invention, roll squeezer is finished the extruding of coarse fodder (comprising raw material) is pulverized; Described classifying screen is finished the stock grading after the roll squeezer extruding is selected powder; Described conveyance conduit is finished the conveying of particulate material, fine grained material and powder; Described material-receiving system provides the required ventilation of aforementioned roller press grinding system and the requirement of gathering dust; Described control system realizes control and system's interlocking of aforementioned each system equipment.Double roll press grinding system in parallel adopts two cover roller press grinding system parallel waies to install and produce, and two cover roller press grinding systems can move production simultaneously, also can singly overlap independent operating production; Two covers roller press grinding system in parallel can be produced identical material, also can produce different qualities or different types of material
Advantage of the present invention is: technological process of the present invention is simple, and easy to operate, reliable, the mode of production is various, and allotment is given full play to the energy-saving and cost-reducing characteristics of roller press grinding system flexibly, finishes pulverizing and the grinding work of material, reduces the grinding system power consumption.
