How to use the concrete grinder

In the process of using, hold the lever and start the gasoline engine first, the shovel will rotate to polish the concrete floor. The polishing machine can polish 100-30 square meters per hour, which can increase the working efficiency more than 3 times compared with manual polishing. The main structure is a scraper rotor driven by a gasoline engine with 2 to 4 scrapers on a cross bottom in the center of the rotor.

the choice of the vertical mill should pay attention to the following aspects

1、Ensure the production capacity of the mill

The grinding equipment selected by the manufacturer can achieve the required power under the condition of ensuring the required grinding precision.

2、The production capacity should be higher than the design

The design plan should consider the transformation of iron ore strength and grain size, usually, the deep iron ore in the ore-forming layer becomes harder or narrower, and should also combine with the crusher used and ensure the successful completion and commissioning of the early stage.

3. Ensure that crushing experiments are carried out

When there is no specific material as a basis in the design scheme, it is necessary to specify crushing experiments, especially for medium and large mining plants, the selection and calculation of crushers must be carried out from the data obtained, and the proportion will become larger.

4, give due consideration to the import substitution of machinery and equipment

The import substitution of machinery and equipment is the trend of design solutions in the 21st century so far. Due to the use of imported machinery and equipment substitution, the total weight of machinery and equipment is lighter, small footprint, small production system, the actual operator and auxiliary system software is less, the project investment and input is relatively low, however, the actual operation and management capacity of large and medium-sized machinery and equipment is high, if the work rate is slightly reduced, the production of mining plants will be greatly reduced.

5, the use of the high operating rate of machinery and equipment

In the same type of machinery and equipment, there is also the difference between old and new, rod mill and autogenous mill sometimes run at a slower speed, but in special conditions can still be used, under normal circumstances, should use high operating rate of machinery and equipment to reduce maintenance and stopping time.
