Description
Technical field
The utility model relates to a kind of slurry preparation facilities, more particularly, to a kind of production of water-saving high solids content slurry
Line.
Background technique
It is well known that the varieties of resources of China's metal and nonmetallic ore are very rich, processing is had become with using this kind of resource
For the important component of socio-economic activity, with the rapid development of social economy, for efficiently utilizing for these resources
Problem is increasingly burst, and mineral resources are made that huge contribution to the sustainable development for ensuring economy, but also gives the guarantor of social environment
More stringent requirements are proposed for shield, how further efficiently to utilize these mineral resources, and reduce influences especially to weigh on environment bring
It wants.
Currently, generally use and ground with the wet type that water is flowing phase medium during industrialized utilization mineral resources,
Each quasi-mineral is milled into through broken, wet type the slurry of various concentration, various fineness, in order to the conveying of minerals, metering,
Outstanding and more suitably physics and chemical mode application is floated in chemistry leaching, physics.
With the fast development of all types of industries application technology, resource is fewer and fewer, due to industrialized fast-developing ring
Border problem does not solve in time, and country is increasingly strict to raising resources development and utilization rate and environmental protection requirement.
In general, the production process of wet type slurry is relatively simple, single grinding machine is generally used, the granularity of the slurry ground is in
Existing random distribution, concentration is lower, and the efficiency of grinding machine ore grinding is lower, and the power consumption of the processes such as grinding machine, conveying, stirring is larger, consumption
Water is more, brings adverse effect to the utilization of subsequent slurry, various consumption increase, and the water that need to be consumed is larger, to cause to give birth to
Produce enterprise operation increased costs, economic benefit decline.
For this purpose, it is badly in need of a kind of New type wet slurry production method for being easy to industrializing implementation, it is effective in slurry to improve
The content of mineral reduces the moisture into slurry, increases the effective content of mineral substances of unit slurry, reduces all kinds of of production process and disappear
Consumption promotes Business Economic Benefit.
In slurry grinding process, the content of the effective minerals of slurry is improved, maximally efficient method is by reducing this
Gap between a little mineral particles and inside particle, and fill it by more tiny mineral particle, between raising particle
Charging efficiency, it is possible to reduce filling of the mobile phase water to particulate interspaces, so reduce flowing water phase dosage, to realize
Improve the purpose of effective content of mineral substances.
In recent years, novel broken and grinding attachment system constantly comes out, and promotes the development for crushing milling technology, such as each
Kind crusher, coarse powder flour mill, ball mill, rod mill, atomizer mill, ultra-fine grinding mill etc..While innovation, engineers and technicians
It is also dedicated to employ new technology, new material and coming of new technique etc., traditional crushing and grinding machinery be improved, to mention
Its high craftsmanship and working efficiency, reduce the consumption of its quality and abrasive body, facilitate Operation and maintenance.
Such as the production process of certain domestic heavy calcium carbonate slurry, using two stage grinding, but every kind of grinding machine is added to difference
Medium ball improves efficiency, and granularity is thinner, concentration~65% of slurry, but the energy consumption of production unit slurry is high.For another example domestic most
Process production water-coal-slurry is regrinded using what single rod mill/ball mill or colloid were ground by water-coal-slurry factory；These water-coal-slurry
Concentration 58-62%, viscosity 0.5-1.2Pa.s, about 125 μm of average particle size, the concentration of these coal slurries is relatively low, and water consumption is bigger than normal.
Wet pulverizing prepares slurry, regardless of which kind of process engineering used, especially in powder metallurgy, the works such as metal and nonmetal
In industry, the media such as water of application should lack as far as possible, or using not Ke Xunhuanliyong high concentration high pollution waste water, reduce disappearing for water
Consumption and discharge amount.Currently, muck and grinding attachment develop to enlargement, efficient, reliabilization and energy-saving direction.
