The invention discloses a raw material pretreatment process for extracting vanadium from vanadium slag. The process comprises the following steps of: a, performing wet ball milling on the vanadium slag, and filtering the vanadium slag; b, drying the vanadium slag filtered in the step a in a drying kiln, and controlling the drying temperature to be between 150 and 300 DEG C; …
The mill produces optimum-quality, high-resistance cement with a lower Blaine, and enables an exceptionally high cement/clinker ratio. The FCB Horomill® helps cement producers reach sustainability goals through: The lowest energy consumption on the market (30-65% energy savings compared to ball mills, and 10-20% compared to vertical roller mills)

Because the mill can utilise much higher quantities of hot gases for drying than both a ball mill or a roll press with ball mill circuits, it means that the percent substitutions of slag, and other wet materials is not limited by the system's drying capacity.
MLS3626 vertical mill is used to grind raw materials, and waste gases from preheater are applied in drying. The whole production capacity is 185t/h. Grinded raw meal is separated by the fine powder separator, and then mixed with powder in the conditioning tower and electric environmental protection equipment.
Approximately 227 kg product capacity (depends on density) Wet Ball Milling. Hardened alloy spherical steel grinding media. Load capacity of 454 kg - 11,340 kg 1 mill at 454 kg capacity; 1 mill at 1,815 kg capacity; 7 mills at 2,268 kg capacity; 1 mill at 11,340 kg capacity
The drying heat source is provided by an air heating furnace. 2. Production Process by Ball Mill. Slag is transported into the plant by truck and stored under the shed. After reclaiming by loader and metering by feeder, the material is delivered into the dryer by belt conveyor for drying. After drying the slag enter the ball mill for grinding.
Raw material drying method of vertical mill grinding system. As far as new dry-process cement is concerned, the requirements for the drying capacity of raw meal preparation are quite strict. The raw material moisture control index is <1%, and now cement factories generally control it within 0.5%. Raw material vertical grinding system, material ...
High drying capacity, short dwell time of the material to be ground, and remote control of grinding pressure and classifier rotor speed ensure a fully automatic operation of the MPS mill even with varying raw material characteristics.
The ball mill was simulated as a single compartment mill by eliminating the mill length of 2.935 m which was used in drying stage, such that the full length (L = 9.87 m) of the mill was used in grinding. Thus, drying of the raw meal outside the …

Fig.2 Schematic process flow of vertical roller mill for grinding of raw materials Vertical roller mills are adopted in 20 cement plants (44 mills) in Japan. Results Table Energy saving effect of the vertical roller mill Ball mill ...
The Production method usually adopts advanced dry process cement production technology. independent production, independent development, manufacturing, installation and commissioning, product sales and technical services with an …
1.High grinding efficiency: save 20~30% power consumption compared with the ball mill. 2.Strong drying capacity: dry and grind raw materials with moisture content as much as 15%. 3. Mutifunction: crushing, drying, grinding, separating and conveying. 4.
This paper presents results of the research of micronization grinding of dry mica in a planetary ball mill. Investigation was conducted in order to improve the quality and to obtain clearly defined properties and characteristics of mica powder. The micronization grinding of dry mica was performed in four time periods: 30, 60, 120, and 360 minutes.
Ball mill could wet grind and dry grind many kinds of minerals and grindable material, according to different ore discharge methods, there are grid type and overflow type ball mill. 1.Discharge port Reasonable discharge port design, de-ironing separator could be set according to …
Ball mill is a traditional coal pulverizer machine, which has been widely used since it was invented. In the cement plant, the new dry process cement manufacturing requires the moisture content of coal powder to be 0.5% ~ 1.5%, while that of raw coal is 1.5% ~ 4.0%.

Material drying occurs in the air suspension between table and classifier in a VRM. 7 For Ball Mill drying, a separate dryer is required ahead of the mill. In some cases, if the moisture is not too elevated, the drying may be done in the ball mill classifier as shown in Figure 4 below. Figure 4 – Example of a ball mill grinding plant with a HGG
Ball mills for cement raw material and coal equipped with a drying compartment adequately air swept with hot gas (2.5-3.5M/sec above the ball charge), can handle moisture about 8%. Fully air- swept mills (5-6M/sec) can dry up to 12-14% moisture.
2. Strong drying capacity: it can make use of hot waste gas from kiln to do drying, and it is capable of drying and grinding raw materials with moisture content as much as 15%. 3. Small in size, and simple process flow: it has integrated crushing, drying, grinding, separating and conveying into one body. 4.
Occasionally, the mill is preceded by a hot-air-swept hammer mill which does most of the drying and produces millimetre-sized feed for the mill. Ball mills are rather inefficient, and typically require 10–20 kW·h of electric power to make a tonne of rawmix. The Aerofall mill is sometimes used for pre-grinding large wet feeds.
Inside the ball mill, the crushed iron ore will grind the ore to about 0.2 mm with 3-inch steel balls. 3.This iron ore slurry is pumped to the agitation tank. This iron ore slurry is finally pumped to the flotation machine with the fine sulfide ore (~-0.074 mm) going to …
Therefore, dry grinding in a jet mill is the best method, with the material then requiring blending into a wet dispersion. The end material must be dry, and the size goal is 500 nanometers (very small). In this case, a wet media mill must be used, and the material needs to be dried after particle size reduction.
Let us present an easy and convenient service for calculating ball mill capacity. Ball mills are one of the most common and popular type of industrial equipment. They come in a wide variety of modifications and can be used in mining, oil, drilling, agrochemical, and many other sectors. Production of paints, construction materials, dry ...
