Description

A kind of roller with automatic blanking and discharging functions cuts grater
Technical field
This utility model belongs to nonmetallic mineral superfine grinding preparing technical field, cuts grater particularly to a kind of roller with automatic blanking and discharging functions.
Background technology
In industrial and agricultural production, often need to use grinding machine that various materials are carried out pulverization process.Grinding machine, according to milling medium and the difference of grinding material, can be divided into: ball mill, column mill, rod mill, tube mill, autogenous tumbling mill, rotation mortar formula roller mill, Vertical Mill, multilamellar Vertical Mill, vertical roll grinder, DMC grinding machine etc..Commonly used intermittent ball mill in Ceramic production, using wet production, its abrasive action can be divided into two parts, one be between abrasive body and abrasive body and simplified between abrasive action, two is percussion during abrasive body whereabouts, will start with from these two aspects to improve grinding efficiency." much broken and lessmill " technology of metallic ore and technique are topics having carried a lot of years, reduce the mill feed size of ball mill, increase by one section of pre-grinding or ultrafine grinding technique before ball mill, are that the important technology that bargh saves energy and reduce the cost is reformed.The research of grinding machine rock processing is one of emphasis in Mineral Processing Engineering technology.Rock processing is to utilize energy to extrude Ore by grinding machine, roll, impact and grind, make valuable mineral monomer cleavage in Ore (from), the beneficially next stage carries out the process sorted.
Grinding machine is applicable to pulverize the Mohs' hardness such as barite, calcite, potassium feldspar, Talcum, marble, limestone, Gypsum Fibrosum, quartz, active hargil, activated carbon, bentonite, Kaolin, glass, manganese ore, titanium ore, chrome ore, slag and is not more than 7 grades, the nonmetallic mineral that humidity non-flammable below 8% is explosive.Grinding machine uses mill revolution, mill axle rotation, spring to adjust cane grinding roller assembly structure, strengthen grinding roller roller skin to material crushing strength and shear ability; thus reach to strengthen the effect of pulverizing; having the fineness of materials that yield is high, grind high (powder is careful), old-fashioned grinding machine can be with the continuous powder process of dry method (stream time not can exceed that 24 hours), because the bearing in old-fashioned grinding roller assembly is to use grease (grease must shut down filling once so not can exceed that 24 hours in 24 hours).But new-type is that the life cycle using lubricating oil (being commonly called as machine oil) can reach whole grinding roller owing to employing the lubricating oil the longest available machine time is shut down once, changes grinding roller and lubricating oil inspection (being supplemented with some lubricating oil when needing).
Traditional rotary type grater includes the cylindrical tube rotated around the axis of basic horizontal.The cylinder rotated is supplied with the such as granule materials such as slurry or powder, and cylinder is with 3/1 to four/2nds rotations of " critical velocity " (that is, the minimum speed that the material at cylinder inner surface contacts with grater and advances around it) simultaneously.The material of traditional grater cannot realize automatic feed and discharging mostly, easily cause material to pile up in feed pipe, and after stopping feed, the material in feed bin grinds in cannot fully entering cylinder, needing manually to clear up, production efficiency is low and waste of manpower resource.
Roller mill feed arrangement under prior art, must have certain inclination angle in charging aperture front and back end by operator neat for the charging manual sorting being placed on material platform, under the effect at inclination angle, charging aperture front and back end, will feed in roller mill when charging.Such manual sorting adds the workload of operator, and charging cannot roll on material platform, and efficiency is the lowest.
