2. Lithium Slag Dryer

The lithium slag dryer mainly consists of a heat source, feeding device, feeding conveyor, rotary drum, discharge conveyor, induced draft fan, dust collector, and power distribution cabinet. The working principle of this equipment set is as follows: : Due to the certain stickiness of lithium slag, the wet lithium slag entering the drying drum is divided into the following working zones: : First is the material guiding zone, where wet lithium slag contacts high-temperature hot air to quickly evaporate moisture. The lithium slag is moved by large-angle guide plates, preventing adhesion and being guided to the next working zone. ; Second is the lifting and cleaning zone, where the wet material is lifted by lifting plates forming a material curtain. When lithium slag falls, it tends to stick to the drum wall. In this zone, a cleaning device is designed to reasonably clean the lithium slag adhering to the inner wall. During this process, the cleaning device also breaks up lithium slag agglomerates, increasing the heat exchange area and improving drying speed. ; Third is the inclined lifting plate zone, where the wet lithium slag is in a low-moisture loose state and no longer sticky. After sufficient heat exchange, the lithium slag reaches the required moisture level and enters the discharge zone. ; Fourth is the discharge zone, where no lifting plates are set in the drum. The lithium slag rolls and slides to the discharge port, completing the entire drying process.

3 Petroleum Coke Dryer

The vacuum residue oil from petroleum is cracked and coked at 500-550 °C. Petroleum coke is a product formed by separating light and heavy oils through crude oil distillation, followed by thermal cracking of heavy oil. The petroleum coke dryer is a specialized drying equipment developed by our company for materials like petroleum coke. The internal structure of the dryer uses a combination of various high-efficiency lifting plates to effectively control the drying process and heat distribution. The exhaust gas discharge temperature is low, and heat utilization is high. It can achieve intelligent control with one-button operation, automatic adjustment of operating parameters, and the dryer always runs in the optimal state, ensuring uniform and stable moisture content of the dried material. It is more energy-efficient than traditional dryers. Modular dust collection and purification with heat recovery configuration ensure safety and environmental protection. The equipment is equipped with multiple energy-saving new hot air furnaces, which are highly efficient, energy-saving, controllable in heating, simple to operate, and reduce energy consumption by up to 30% around, 20% with lower electricity consumption and reduced operating costs.

4 Sludge Dryer

The sludge dryer is suitable for urban sludge drying. Drying treatment of sludge makes it possible to use sludge for agriculture, as fuel, for incineration, and to reduce landfill space.

With the enhancement of national economic strength and increased environmental awareness, the urban sewage treatment industry has developed rapidly, and the production of urban sludge is increasing daily. The disposal and utilization of sludge have become a growing concern.

The sludge dryer is a very mature drying equipment produced by mining equipment manufacturers, suitable for drying sludge, magnetic, heavy, and flotation concentrates of metal and non-metal mines, as well as clay in the cement industry and other sectors. Its features include high productivity and easy operation. The cylinder is a horizontal rotary drum with various lifting plates welded inside at different staggered angles from front to back. Depending on user requirements, the interior can be designed with refractory material insulation. At the feeding end, a door ring and spiral lifting plates prevent backflow. It has advantages such as reasonable structure, fine workmanship, high output, low energy consumption, and easy operation. Additionally, after years of unremitting efforts by our R&D department, boiler flue gas can be used as the heat source for the sludge dryer, successfully launching a dryer that utilizes boiler waste gas. This means heating without investment and heat usage without cost, truly energy-saving drying and environmentally friendly.

5 Coal Slime Dryer

The coal slime dryer is a rotary drum or rotary cylinder drying machine, a very mature drying equipment produced by mining equipment manufacturers. It is suitable for drying coal slime from the coal mining industry, sludge, magnetic, heavy, and flotation concentrates of metal and non-metal mines, as well as clay in the cement industry and other sectors. Its features include high productivity and easy operation. The cylinder is a horizontal rotary drum with various lifting plates welded inside at different staggered angles from front to back.

6 Compound Fertilizer Dryer

The compound fertilizer dryer is a supporting device for organic compound fertilizer production lines. The finished granules are fine and can be used as a substrate for cultivating edible mushrooms such as Agaricus bisporus, or sold as feed for breeding turtles, fish, snails, chickens, ducks, and others.

With the increased development of agriculture in our country, agricultural and sideline products are receiving more and more attention. The pollution caused by poultry and livestock manure to the environment is becoming increasingly serious. However, cow dung contains rich nutrients and trace elements and is an excellent organic fertilizer. Developing cow dung into compound organic fertilizer can not only turn waste into treasure but also reduce environmental pollution, prevent the spread of diseases, and has good economic and social benefits.
