Gypsum and gypsum powder fineness

There are two types of gypsum powder, one is β gypsum powder (also called ordinary gypsum powder), and the other is α gypsum powder (also called high-strength gypsum powder). The fineness of β gypsum powder is generally 80 to 90 meshes, and the standard consistency requires a large amount of water, and the strength of the model is low; the fineness of α gypsum powder is generally 100 to 180 meshes, and the standard consistency requires a small amount of water and the strength of the model is high.

YGM Gypsum high pressure suspension mill is the ideal model for producing these two types of gypsum powder.

Product description of YGM Gypsum high pressure suspension mill

 
Feed size: 0-25mm
Discharge fineness: 120-325 mesh
Processing capacity: 0.6-25t / h
 
 
[Application field]
Large and medium-sized mining, chemical, building materials, metallurgy, refractory, pharmaceutical, cement and other industries.
 
[Applicable materials]
Processing of various non-flammable and explosive ores with a Mohs hardness of less than 7 and humidity of less than 6%, such as gypsum, talc, calcite, limestone, marble, barite, dolomite, granite, kaolin, bauxite, oxidation Iron red, iron ore, etc.

High pressure suspension mill is applicable to non-combustible and explosive mines, metallurgy, chemical industry, building materials and other industries where the Mohs hardness of crushed gypsum, barite, limestone, ceramics, and slag is not greater than 9.3 and the humidity is below 6% High-precision milling of more than 280 materials, and the particle size of the finished product is adjusted in the range of 80-425 mesh. This machine can produce 30-80 mesh coarse powder by adding special equipment.
 
 

Equipment advantages

 
1. Low production cost, good stability and high performance
The base is made of high-strength, anti-vibration nodular cast iron, and the middle body and the base are soft-connected without rigid contact, which effectively prevents the vibration generated in the grinding chamber from being transmitted to the middle body and the analyzer to cause damage to the components, which can also effectively improve the analysis accuracy .
 
2. Excellent reducer, overload protection
Adopting excellent reducer, stable operation and reliable performance, effectively improve the stability of the whole machine. The reducer and motor use a V-belt to transmit power, which is conducive to overload protection.
 
3. The analysis machine adopts variable frequency speed regulation
The analysis machine adopts frequency conversion speed regulation, which saves energy compared with electromagnetic speed regulation, accurate speed control, good process control mobility and high degree of automation.
 
4. Cyclone powder collector
The powder collecting efficiency is high, the investment cost is low, and most of the fine dust can be isolated during the powder collecting process. The cyclone powder collector collects powder in a fixed amount, which effectively reduces the pressure loss of the entire wind system. Users can also choose "bypass powder collector" according to the dust content of the finished product to reduce the dust content.
 
 

Product structure and working principle

 
In the high pressure suspension mill main unit, a high-pressure spring with a pressure of 1000-1500 kg is fastened on the grinding roller hanger. After starting work, the grinding roller rotates around the main shaft and rolls against the grinding ring under the action of high-pressure spring and centrifugal force. Its rolling pressure is 1.2 times higher than the Raymond mill under the same dynamic conditions, so the output is greatly increased. After the material to be ground enters the grinding chamber, it is lifted by a shovel blade and sent between the grinding roller and the grinding ring for rolling. The rolled powder is brought into the analysis machine with the circulating air of the blower, and the qualified fine powder enters the cyclone with the airflow. The pulverizer is the finished product, and the large particles fall back to the mill.
