vertical roller mill working principle
Vertical roller mill is one of the most important production equipment in mine machinery equipment, manufacturing Shanghai SBM Machinery Co. Ltd. perennialengaged in mining machinery equipment, wherein the vertical milling machine is my company's flagship product, our company focus on the production of innovative vertical milling machine, milling machine and strive to provide customers the best quality.
Vertical roller mill is mainly suitable for medium, low hardness, superfine powder processing Mohs hardness of less than or equal to grade 6 non flammable and explosive brittle materials, such as calcite, chalk, limestone, dolomite, carbon black, kaolin,bentonite, mica, talc, magne site, illite, Ye La stone, vermiculite, sepiolite, attapulgite stone, rectorite, diatomite, gypsum, barite, fluorite, alunite, graphite, potassium ore,phosphate rock, pumice and other 100 kinds of material, fine powder product size in the 325-3000 project between the arbitrary regulation, yield up to 0.7-7.5 tons per hour.Vertical milling machine full set of configuration includes hammer crusher, bucket elevator, a storage hopper, vibration feeder, micro powder mill, classifier, host frequency duplex cyclone powder collector, pulse high pressure air dust removal system, machine,air compressor, electric control system.
The work of vertical milling machine, the host motor through the speed reducer drives the spindle and the rotation of the turntable, turntable driven roller pin edge dozens of roll grinding in grinding ring raceway of rolling. Bulk materials by a hammer crusher broken into small particles by the hoist into the storage bin, and then through the feeding tubevibration feeder and the tilt of the disc material, bulk material evenly to the upper part of the turntable. Effects of material under the centrifugal powder to circular perimeter, and fall into the mill raceway was ring roll impact, rolling, grinding ring, after processing threelayer loop into powder, high pressure blower through the pumping action will be the external air suction machine, and the crushed material into powder selecting machine in.Choose the rotation of an impeller powder inside the machine make coarse material fallheavy grinding, comply with the requirements of the fine powder with the air flow into thecyclone powder collector and from the lower part of the discharge valve discharge is finished, the air flow with a small amount of fine dust through the pulse dust collectorafter purification by the blower and the exhaust muffler.
Introduced the working principle of the above is vertical milling machine, with the majority of customers after SBM of the vertical milling machine is introduced simply, the work principle and application of it have a preliminary understanding. However in the vertical mill work still need to pay attention to a lot of relevant details, such as attention, vertical mill in operation and maintenance etc..
