CemMate 100
Grinding type cement grinding aid

Description
CemMate 100 is a kind of grinding type cement grinding aid.
By the use of CemMate 100, without the new investment and change of existing cement grinding process equipment, it can be realized that:
- Mill output is increased;
- Energy cost is reduced.

Scope of the application
Suitable for grinding of any kinds of cement, slag powder, steel slag powder and limestone powder.

Property
Appearance
Brown liquid
Specific gravity
1.16±0.05
PH value
9±1
Insoluble matter
â?¤ 0.01%

CemMate 100 is non-toxic, non corrosive, non flammable, non explosive.

Technical characteristic
- Increasing mill output. This product can effectively remove the electrostatic agglomeration due to grinding, reduce the agglomeration between cement particles, and the agglomeration between particles and pound mills. The mill output can be increased by 10ï½?20%. For the grinding of slag powder or steel slag powder, the mill output can be increased by ï½?10%.
- Reducing energy consumption. The electricity used in the production of per ton of cement can be saved by 6ï½?10 kw/h.
- Others. There is no corrosive effect on grinding equipment and concrete reinforcement. Basically, it does not affect cement setting time and water consumption of standard consistency. Cement strength can be increased slightly. It has no adverse effect on the work performance, mechanical properties, deformation performance and durability of concrete.

Dosage
The dosage of CemMate 100 is related to the physical properties of materials to be grinded.
The recommended dosage is 300 grams / tons of materials to be grinded (0.03% of cement weight).

Usage method
In order to achieve the most stable using effect, CemMate 100 shall be accurately added by an adjustable liquid metering pump that matches the type and output of the mill. The liquid metering pump must be calibrated before use.
CemMate 100 can be added to the belt conveyor or the front of the mill.

Technical service
Professional engineers can combine the details of the cement plant to make experiment and recommend the mill parameters to the cement plant.
CemMate 100 is one kind of cement grinding aid. According to the condition and demand of cement plant, professional engineers can design the most suitable cement grinding aid for many kinds of cement from cement plants to adjust cement performance, such as: setting time, water requirement of normal consistency, fluidity, adaptability of cement concrete, etc.

Package
200 L/drum, intermediate bulk container.

Storage
CemMate 100 should be stored indoors or in the shade. Avoid freezing. If it is frozen, melt it slowly before use. After long term placement, it should be stirred or shaken before use. The validity period is one year.

We provide free sample for mini mill test and technical support throughout the whole application process.
We look forward to the cooperation with the agent worldwide.

Casting iron balls include high chromium balls, medium chromium balls and low chromium balls.

Quality index of high chromium casting ball:

The chromium content of the high chromium ball is 10.0% or more. The carbon content is between 1.80% and 3.20%. According to national standards, the hardness of the high chromium ball must be no less than 58hrc, and the impact value should be greater than or equal to 3.0j/cm2. To achieve this hardness, the high chromium ball must be quenched and tempered at high temperature. At present, there are two methods for quenching high chromium balls in China, including oil quenching and wind quenching. If the test hardness of the high chromium ball is lower than 54HRC, it means that it has not been quenched.

Quality index of medium chromium casting ball

The specified chromium content of the medium chromium ball ranges from 3.0% to 7.0%, and the carbon content is between 1.80% and 3.20%. Its impact value should not be less than 2.0j/cm2. According to national standards, the hardness of the chrome ball should be greater than or equal to 47hrc. In order to ensure quality, medium chromium balls should be tempered at high temperature to eliminate casting stress.

If the surface of the iron ball is black and red, it proves that the iron ball has been tempered at high temperature. If the surface of the iron ball still has the metal color, we can judge that the iron ball has not undergone high temperature tempering treatment.

Quality index of low chromium casting ball

Generally speaking, the chromium content of the low chromium ball is 0.5% to 2.5%, and the carbon content is from 1.80% to 3.20%. Therefore, according to the national standard, the hardness of the low chromium ball should be no less than 45hrc, and the impact value should be no less than 1.5j/cm2. Low chromium balls also need high temperature tempering treatment to ensure quality. This treatment can eliminate casting stress. If the surface of the iron ball is dark red, it indicates that it has undergone high temperature tempering treatment. If the surface is still metallic color, it means that the iron ball has not been tempered at high temperature.

Casting iron balls are usually used in various large-scale mines, cement plants, chemical plants, power plants, quartz sand plants, silica sand plants, etc.
