Which is better, ring mill or vertical mill? Which is the most widely used ring mill or vertical mill? The vertical mill is the "net celebrity product" of mine grinding equipment in the past two years. It is highly efficient, energy-saving, green and environmentally friendly, and the company has zero pressure to pass the environmental assessment. Ring mill is what we usually call ring roller mill. Because of its price advantage, it is an economical and practical product for processing ultrafine powder, so it is loved by many enterprises.


Which is better in appearance?

The vertical mill is mainly composed of a main engine, a feeder, a classifier, a blower, a pipeline device, a storage hopper, an electric control system, and a collection system. It is mainly vertical and occupies only 50% of the area of the ball mill.

The ring roller mill is mainly composed of main machine, feeder, classifier, blower, pipeline device, storage hopper, electric control system, collection system and so on. Grinding wheels and rings are made of special wear-resistant steel with long service life.

Which is the most convenient way to install?

Both the ring roller mill and the vertical mill are vertically installed, with less system equipment, compact structure layout, small footprint, short cycle time, convenient installation and low construction cost.


Which one is more energy efficient?

The vertical mill uses a motor to drive the reducer to drive the grinding disc to rotate. The material to be ground is sent to the center of the rotating grinding disc by the air lock feeding device. Under the action of centrifugal force, the material moves to the periphery of the grinding disc and enters the grinding roller table. Under the action of the pressure of the grinding roller, the material is crushed by extrusion, grinding and shearing.

ultrafine vertical mill


The ring roller mill uses the jaw crusher to crush the material into a material smaller than 10mm, lifts it to the storage hopper through the bucket elevator, and then sends it to the main machine cavity by the feeder for grinding. The grinding roller installed on the turntable in the main machine cavity Rotating around the central axis, there is a large movable gap between the grinding roller and the grinding roller pin. Under the action of centrifugal force, the grinding roller swings horizontally outward, so that the grinding roller presses the grinding ring, and the grinding roller rotates around the grinding roller pin at the same time.

Which particle size is finer?

The finished particle size of the vertical mill can be adjusted arbitrarily between 300-3000 mesh. If the finished product particle size of the ultra-fine vertical mill is 3-45μm, the equipment has a variety of models of 1-40t/h to choose from.


CLUM vertical mill: 20-5 micron(600-3000 mesh); D50=2 micron D97=4 micron


The finished particle size of the ring roller mill can be adjusted arbitrarily between 200-2500 mesh, and the equipment has various models of 1-22t/h to choose from, and the product fineness can reach D97≤5μm at one time.


HGM ring roller mill: 74-5 micron(200-2500 mesh); D97=5 micron


Which is more environmentally friendly?

The vertical mill adopts a cyclone dust collector and an explosion-proof bag-breaking dust collector. The after-sales engineer will choose a secondary dust collection system or a stand-alone dust collection system for the user according to different configuration schemes. The ring grinding adopts a full pulse dust collection system, and the dust collection rate is as high as 99.9%.


Production line composition of ring roller mill and vertical mill

CLUM vertical mill is mainly composed of motor, reducer, grinding wheel device, disc grinding device, pressurizing device, powder classifier, secondary powder classifier system, feeding device, oil station, main engine, electric control system and other parts.


vertical mill production line


The complete configuration of HGM ring roller mill includes bucket elevator, storage bin, vibrating feeder, ring roller mill host, frequency conversion classifier, double cyclone powder collector, pulse dust removal system, high pressure fan, air compressor and electrical control system etc.


ring roller mill production


Comprehensive comparison, both the vertical mill and the ring roller mill have their own advantages and characteristics, we cannot unilaterally decide which is better, the ring mill or the vertical mill. The vertical mill has a large capacity and is more suitable for large-scale and expanded production. Ring milling is suitable for the production of ultra-fine powder for small and medium-sized enterprises because of its energy-saving advantages, and the price is more affordable. If you need to compare the two products in more detail and select more parameters, please feel free to contact us at any time, leave the material you need to grind and the fineness of the product, and we will contact you within 24 hours.
