Limestone is a common form of non-metallic mineral, is highly versatile precious resource. In the history of human civilization, limestone has been widely used for its widely distributed in nature and easily accessible features.  As an important building material, limestone has a long mining history, in modern industry, limestone is the main raw material for the manufacture of cement, lime, calcium carbide, and it is indispensable flux in metallurgical industry. Hgih quality limestone after ultrafine grinding, is widely used in manufacturing paper, rubber, paint, coatings, pharmaceuticals, cosmetics, animal feed, sealing, bonding, polishing product.

Sand and gravel is an indispensable raw material for construction, highway, railway and other industries. Equipment selection is the top priority. Small stone crushers are inquiring every day due to their small size and low price. Let’s introduce the type, performance, price and other details of small stone crushers.

1. Small jaw crusher
The jaw crusher is known as the “tiger’s mouth”, it can crush both soft and hard materials. The crushing chamber is large and has special parameters. It can be crushed from the upper part to fully crush the material. At the same time, the use of highly wear-resistant materials can reduce equipment wear and extend service life.

2. Small cone crusher
The cone crusher adopts the principle of squeezing and crushing, which can be used for medium and fine crushing of high hardness materials. Equipped with a PCL control system, the operation mode is adjusted by one button, and the degree of automation is very high. In an emergency, the host can be actively shut down to protect the core components.

3. Small impact crusher

Impact crusher uses the principle of impact crushing and is generally used for materials with medium hardness or less. The finished product is three-dimensional, because crushing high-hardness materials will severely wear the hammer, and there is less powder in the production process, which can make full use of materials and improve product value.

4. Small mobile crusher

Mobile crusher equipment is a design with multiple advantages, which can realize the integration of feeding, crushing and screening, and can be customized according to the customer. The overall body is reasonable and compact, and it can be used directly at the production site without piling. It is equipped with a remote control system to facilitate changing the production mode.

Coconut shell activated carbon,a highly porous adsorbent material, produced by heating coconut shell, in the absence of air, which is then crushed into granules, grinded into powder.It has a very high hardness and is more abrasion resistant than any other type. It is a totally natural, environmentally friendly product.

Compared with activated carbon with coal based, wood based, coconut shell activated carbon has following feathures:

Very high surface area characterized by a large proportion of micropores
High hardness with low dust generation
Excellent purity, with most products exhibiting no more than 3-5% ash content.
Renewable and green raw material.

Dawn produces LM vertical mills, which is used to process 200-mesh power plant desulfurized limestone powder. The calcium desulfurization process is sprayed in the furnace, and an additional humidification section is added to the boiler to improve the desulfurization efficiency.The capacity is 20 tons per hour, and the detailed configuration is as follows:

Mill configuration: vertical mill, main motor power 280KW.

Finished product size: 200 mesh = D80

Production capacity: 18-20 t/h

Customer case: A thermal power plant uses 600MW units and more than 10 LM vertical mills. It has been in operation for more than six years.

Customer evaluation: The LM150M vertical mill runs well, its performance is stable and reliable, its maintenance is convenient, its automation

is high, and its operation is convenient. It has contributed a lot to the continuous power supply of our thermal power plants.

The Dawn is a large-scale production and export base of crushing and screening equipment,  we develop and produce a variety of fixed and mobile crushing plants.

According to different vehicle traveling system, its mobile crushing station equipments are divided into two types: tire type mobile crushing station and crawler mobile crushing station.

In accordance with the different main crusher, mobile crushing plants are divided into: jaw crusher mobile crushing plant, cone crusher mobile crushing plant, impact crusher mobile crushing plant, sand making machine mobile crushing station,etc.

For more information, please let us know the material; capacity ton one hour etc. With the clear production requirements we can configure the most suitable equipment models.

As we all know, 150 mesh talc powder is widely used in many field. With the further development of industry, demand for talc powder is increasing. According to this market trend, Dawn launched MTW Heavy type Trapezium Mill, an upgraded product of Raymond Mill.

The advantage of MTW Heavy type Trapezium Mill:

1.Bevel gear overall drive. Transmission chain is less but transmission ratio is accurate. Energy consumption is reduced by 20-30%.

2.This machine adopts internal thin oil lubrication system to get better lubrication effect. The oil exchange cycle is long and it is easy to maintain.

3.This machine adopts new hanging type cage classifier, which can improve classifying efficiency effectively. There is frequency conversion control and the output size of final products can be regulatable.

4.There are 7 core patents and it adopts new German technology. MTW Heavy type Trapezium Mill has been high-quality products because of high efficiency and low running costs.

5.This machine has got environmental protection certification in industrial products, and it can meet the demand of environmental protection.
