Abstract
The invention provides grinding equipment for a dry type cement production line. The grinding equipment comprises a vertical mill and a ball grinding mill connected with a discharge port of the vertical mill through a belt conveyor or a sliding chute, wherein the vertical mill comprises a discharge port in the top, an efficient powder concentrator arranged below the discharge port, a feed port formed in the middle of the vertical mill, a grinding roll arranged below the feed port, a grinding disc arranged below the grinding roll, a drive arm connected with two ends of the grinding mill, a hydraulic system connected with the drive arm, a spindle connected with the grinding disc, a speed reducer connected with the spindle and a motor connected with the speed reducer. The grinding equipment for the dry type cement production line has the technical effects as follows: grinding equipment is reasonably selected, the product quality is guaranteed, and the energy consumption is reduced.
Description
Technical field
The present invention relates to a kind of dry type used on cement production line milling equipment, belong to field of mechanical technique.
Background technology
Cement producing line is the cement equipment production line of a series of equipment composition producing cement.Main by crushing and pre-homogenizing, raw material are prepared the processes such as homogenizing, pre-thermal decomposition, the burning till of clinker, cement grinding packaging and constituted.
Portland-type cement production technology is representative in cement manufacture plant, it is with limestone and clay for primary raw material, through broken, dispensing, levigate make raw material, then mature calcined material in feeding cement kiln, then grog is added proper amount of gypsum (sometimes also admixture composite material or additive) levigate form.
Cement manufacture plant is different with method for preparing raw material, can be divided into dry cement production line (including semidry method) and wet-process cement production line (including half wet process) two kinds.
1. the cement produced with the dry method technological process of production.Raw material is dried and grinding simultaneously, or first dry to become after raw meal powder, to feed the method for mature calcined material in dry method kiln through grinding.But also have and raw meal powder is added suitable quantity of water make raw material ball, send into the method for mature calcined material in lepol kiln, be referred to as semidry method, still belong to the one of dry production.Dry production have the advantages that heat consumption low (as with the dry method kiln heat consumption of clinker of preheater be 3140～3768 burnt/kilogram), shortcoming is that raw ingredients is not easily uniform, and workshop airborne dust is big, and power consumption is higher.
2. the wet-process cement technological process of production.After the grinding that added water by raw material becomes raw slurry, the method for feeding wet-process rotary kiln mature calcined material.Also have after the raw slurry dehydration of wet-layer preparation, make the method that raw material block enters kiln mature calcined material, be called half wet process, still belong to the one of wet production.The advantages such as wet production has simple to operate, and raw ingredients is easily controlled, good product quality, and slurry pipeline transport is convenient, and workshop airborne dust is few, shortcoming is heat consumption high (heat consumption of clinker be generally 5234～6490 burnt/kilogram).
In the process of cement producing line, often produce 1 ton of portland cement and at least want 3 tons of materials of grinding (including various raw material, fuel, grog, compound, Gypsum Fibrosum), according to statistics, dry cement production line grinding operation needs the power consumed to account for more than the 60% of full factory power, wherein raw grinding accounts for more than 30%, coal mill accounts for about 3%, and cement grinding accounts for 40%.
Accordingly, it would be desirable to rationally select milling equipment, to ensure product quality, to reduce energy consumption.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art part, it is provided that a kind of dry type used on cement production line milling equipment.
The dry type used on cement production line milling equipment of the present invention, by Vertical Mill be connected the ball mill of Vertical Mill discharging opening with by ribbon conveyer or chute and form；Described Vertical Mill includes the discharging opening at top, it is located at the high-efficient powder concentrator below discharging opening, it is located at the charging aperture in the middle part of Vertical Mill, it is located at the grinding roller below feeding mouth, it is located at the mill below grinding roller, the transmission arm being connected with grinding roller two ends, the hydraulic system being connected with transmission arm, the main shaft being connected with mill, the reductor being connected with main shaft and the motor being connected with reductor, described ball mill includes stack shell, it is located at the charge door at stack shell top, it is located at the end cap at stack shell two ends, it is located at the main shaft in stack shell, the bearing block being connected with main shaft, the friction clutch being connected with the bearing block of side, the decelerator being connected with friction clutch, the clutch operating lever being connected with decelerator, the motor being connected with clutch operating lever, it is provided with pot mill in described stack shell to be situated between and liner plate.
The dry type used on cement production line milling equipment of the present invention, has the following technical effect that and rationally selects milling equipment, it is ensured that product quality, reduce energy consumption.
