Description
The utility model belongs to a kind of disintegrating apparatus of non-metallic ore, particularly a kind of raymond mill that obtains 200～2500 order superfines.
The tradition Raymond mill is from introducing China's recent two decades, this machine is mainly used in the pulverizing in enormous quantities of nonmetallic ore material, its product fineness is generally at the 325-400 order, along with socio-economic development, the demand in market, can only producing single meal product, can not to adapt to present development required, is unfavorable for that more nonmetal processing industry economic benefit improves.
In using traditional Raymond mill process, find, during Raymond mill processing calcite class mineral powder, contain a large amount of-10 μ m superfine products in its 325 order meal, it if can be collected, and in addition means improve superfine powder output, and economic benefit is considerable, therefore, this legacy equipment of Raymond mill just awaits by new technology, more scientifically, more systematically, innovating reform makes it produce superfine product, enlarge range of application, improve product economy and be worth.
The utility model purpose provides that a kind of to produce 200～2500 orders adjustable arbitrarily, also can obtain the raymond mill of high-quality coating level slurry simultaneously.From traditional raymond mill circulating collection system works principle (principle schematic is seen Fig. 1) as can be seen:
The tradition Raymond mill is collected powder product and is mainly depended on the willy-willy gatherer, though there is fine powder to obtain by the whirly gatherer, the fine powder quantity that can trap is very little, and carries a large amount of dust pollution surrounding environment secretly by discharging the lingering remnants of past customs.
Above-mentioned situation explanation, the work of the ultra-fine stone flour of traditional not competent production of Raymond mill circulating collection system must be carried out the system reform, forms new circulating collection system, adapts to the production of superfine powder.
By to the comprehensive network analysis of traditional Raymond mill, with the continuous exploration in the actual production, form a ultra-fine stone flour production system of complete, novel Raymond mill, traditional two-stage collection is become level Four collect, collect for 1,2 grade and adopt circular negative-pressure locking formula to collect no dust pollution, 3,4 grades of collections adopt controlled Overruning to do: wet series connection collection, break off dust pollution, whole gathering system when collecting superfine product, also stop or reduce to around environmental pollution.Its system process schematic diagram is shown in Fig. 2 (0 is adjusting device among Fig. 2).
Specifically, the utility model structure is: a kind of ultra-fine raymond mill that nonmetallic mineral can be ground to form superfines, by the main frame that mineral are pulverized and ground (117), the analytical engine (130) that the different grain size powder is separated, the ventilation blower (135) of energy is provided for whole device, an axial flow blower (160), No. two axial flow blowers (132) and aforementioned three parts are connected into whole pipeline, circulation, gathering-device constitutes, analytical engine (130) is installed in the top of main frame (117) and is attached thereto logical, the air outlet of ventilation blower (162) inserts main frame (117) bottom by bellows air intake joint (168), it is characterized in that the ventilation blower import is by fan connector (143), airduct (13), elbow (11) inserts No. 2 cyclone collectors (12), analytical engine (130) top air outlet exports threeway (128) by analytical engine, airduct (15), hemispherical dome joint (14) inserts No. 1 cyclone collector (150), No. 1 cyclone collector (150) top is connected with No. 2 cyclone collectors (12) top by a pipeline and an axial flow blower (160), and on No. 1 cyclone collector (150) and No. 2 cyclone collectors (12) the bottom separating opening locking gas drawing mechanism is housed all, ventilation blower (135) air outlet threeway top is by butterfly valve (134), airduct (125), hemispherical dome joint (124) inserts No. 3 cyclone collectors (126), and No. 3 cyclone collectors (126) top is by No. two axial flow blowers (132) of concentric reducer interface (131), elbow (17), airduct (19) inserts water filtration gatherer (113).
The utility model puts into the melting pot the grinding roller of pulverizing part, makes grinding roller and the grinding roller axle can complementary corresponding running, makes it more durable, bears higher pressure and running speed.(25) one on main shaft pulverizing main frame (117) is fixed on main frame belt pulley (213) center, and the plum blossom cross (22) that passes on labyrinth base (222) and drive sleeve (221) other end, center is gone up outstanding four the grinding roller parts (23) that connect, grinding roller parts (23) bottoms stretch into bull ring (26) but in and phase mutual friction and rotation, main frame bellows (29) are positioned at bull ring (26) all around.
By chamber Nei Tuoshi, change the analytical engine running part into outside chamber rotation two isolation in the hanging drive cavity, strengthen its working stability performance.Main shaft (315) one ends of analytical engine (130) are fixed with belt pulley (31), it passes axle sleeve (33) back and is fixedly mounted on the bearing cap (32,34) with bearing (316), the other end is fixed with impeller (321), blade (36) is fixed on the impeller (321), and impeller and blade are surrounded by clamshell (318), closed circuit ring (323), and the clamshell middle part is provided with the outlet of perforation.
