Recently, news came from the customer’s site that the production line of heavy calcium carbonate with an annual output of 500,000 tons built by Dawning macine was commissioned and operated normally and has been put into production. The client is a large local calcium carbonate milling company. A few years ago, it cooperated with Dawning macine and used several European Type mills. Customers own mines, mainly producing fine calcium carbonate, environmentally friendly putty powder, environmentally friendly water-based paint, activated calcium oxide, green building aggregates, etc.

Due to the increase in orders in 2021, in order to meet production needs and improve the company’s production specifications and standards, the user once again ordered 3 sets of Dawning macineMTW European Type mills to achieve the goal of increasing an annual output of 500,000 tons of heavy calcium powder, and gradually turn to carbonic acid. The cluster development of the calcium industry chain meets the needs of different industries for products, promotes the transformation and development of local enterprises, and realizes that equipment upgrades can drive efficiency upgrades!

The stones enters the jaw crusher,impact crusher for crushing through the feeder. After being classified by the vibrating screen, the various specifications of stones are obtained, so as to obtain the finished stones you need.

Equipment configuration: (silo)—-feeder—-jaw crusher—-impact crusher—-vibrating screen (finished stone)—-conveyor—- (can be made into finished stone).

The Dawn slag vertical mill is a kind of special equipment for grinding industrial waste such as  slag into powder. The mill is of simple and reliable operation with high drying ability.
Finished product fineness: 325-1250 mesh
Feeding size (mm): 50mm
Output capacity: 5-100t/h

For manufactured sand, it has become a kind of hot aggregates because it can even rival natural sand in terms of both physical properties (like partial, aggregates grading, compressive strength and powder content) and structure. More and more investors are care about it.

But it is a question how we choose sand making equipment. There are so many sand making machines in market, which one is what we need.

Actually, it is not difficult for users to choose one proper sand making machine, you can judge it whether it can comply with the standard listed below or not.

1. Whether The Sand Making Machine Can Meet Environmental Standards.

In the current situation of strict environmental protection, a good sand making machine will not pollute the surrounding environment. It will not produce too much dust and sewage. Generally, a high quality machine must be equipped three important parts: confined production space, high efficient dust removal and atomization spray device, ensuring to form a healthy ecosphere.

2. Whether The Sand Making Machine Can Shape Sand Or Not?

The main function of a sand making machine is to shape sand aggregates, which can ensure better finished products. If the sand maker can’t shape aggregates, it is basically the same as an ordinary crusher. A good sand maker combines the principles of “Rock to Rock” and “Rock to iron”, thus the material can be completely crushed and shaped in the chamber. It not only can make sand good partial, but avoid dust from overflowing as well.

Raymond mill is widely used in barite, calcite, potash feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum and more than 280 kinds of materials .

It is used in high-fine powder processing of materials in non-flammable and explosive mineral, chemical, construction and other industries with Mohs hardness not greater than 9.3 and humidity below 6%, such as glass and thermal insulation materials, and the particle size of the finished product is within the range of 80-325 mesh .
