Description

A kind of Novel vertical roll grinder with the outer export agency of mill powder
Technical field
The invention belongs to the Novel vertical roll grinder with the outer export agency of mill powder of grinding system stepped zone in the industries such as building materials, electric power, mine, metallurgy, chemical industry, metal mine.
Background technology
Vertical roller grinder powder separating machine collection is broken, dry, powder grinds, classification is transported in one, production efficiency height, and block, particulate state and powder raw material can be worn into required pulverulent material. Vertical roller grinder adopts the efficient cage modle powder separating machine of sound state combination formula, it is possible to ensures that the specific surface area of material regulates in the reasonable scope, and ensures that material finished product has suitable size distribution, is adopt the efficient powder of bed of material grinding technology principle to grind energy-conservation equipment.
Original vertical roller grinder, material is after mill roller grinds, enter efficient cage type powder by wind effect and carry out classification, fine particle finished product is selected, relatively coarse particles directly returns to mill or air guide ring, middle granule materials imports chute by blanking cone in powder separating machine assorting room and continues grinding to mill, is generally referred to as powder separating machine and returns powder. Material is powder mill in vertical roller grinder, forms a closed cycle process, until material is sorted out as finished product by levigate.
Due to the diversity of material, some materials can exist some difficult mill phase, such as slag, slag, metal tailings, metallurgical slags etc., wherein some irony difficulty mill phase, the existence of difficult mill phase causes material grinding energy consumption to increase, and is difficult to sorting, it is easy to mill and mill roll sleeve cause abrasion. After material is ground by repeatedly powder in Vertical Mill, difficult mill is difficult to be crushed to product grading mutually, this part material easily returns enrichment in material at powder separating machine, novel vertical roller mill powder separating machine is by by this part feed separation out, thus improve the mill efficiency of grinding machine, reduce powder mill and generate energy consumption, increase economic benefit.
Ore grinding vertical roll grinder adopts bed-grinding principle, and collection is broken, dry, powder grinds, classification is transported in one, and mill efficiency height, is used widely at building materials field, and block, particulate state and powder raw material can be worn into required fineness by it.

The advantage that the present invention has and positively effect be: owing to technique scheme of the present invention is fitted on vertical roller grinder powder separating machine, vertical roller grinder powder separating machine is had the following advantages:
1, can not only ensure that the specific surface area of material regulates in the reasonable scope, to selecting the coarse granularity in powder process to regulate and control, and difficult-to-grind materials can be discharged, it is to increase vertical roller grinder mill efficiency, reduction grinding energy.
2, the middle particle being rich in difficult-to-grind materials is led to grinding machine outside, contained difficult-to-grind materials enrichment in grinding machine, reduce the abrasion of mill, mill roll sleeve, add the life-span of wear parts, save production cost.
3, middle granule materials enters to grind raw material relatively carefully relatively, grinds powder separating machine through novel vertical roller and leads to grinding machine outside, reduce material loosening degree, reduces the fluctuation of the bed of material, reduces grinding machine vibration, is beneficial to the steady running of grinding machine.
It is fitted on ore grinding vertical roll grinder and ore grinding vertical roll grinder is had the following advantages:
1, ore grinding vertical roll grinder, adopts bed-grinding principle, mill efficiency height, and ore processing production energy consumption is low, and power savings advantages is obvious, saves production cost.
2, ore grinding vertical roll grinder, adopts dry grinding dry separation technology, without the need to water in production process, has stopped the waste of great lot of water resources, be beneficial to environment protection.
3, ore grinding vertical roll grinder, what all adopt compared with high pressure roller mill is bed-grinding principle, but vertical roll grinder is collection powder mill, selects the equipment of powder one, and technical process is simple, and Equipments Setting quantity is few, and cost of investment is low.
4, ore grinding vertical roll grinder, adopts roller drive, mill driven, effectively reduces the velocity contrast between mill roller and mill, reduce the abrasion of equipment wear parts, reduce production maintenance cost.
Present configuration is reasonable in design in sum, simple possible, dismounting and easy to adjust and manufacture and maintenance cost cheap, there is huge economic benefit.
