Outline of LDHM Rotary Dryer:
As a rotary dryer drying equipment mining equipment in use extensively. Divided into direct heat rotary drum dryer and indirect heat rotary drum dryer.
Rotary drum dryer is also known as drum drying equipment or tumble dryers mining equipment is the most common and widely used as a drying machine equipment. Suitable for drying the magnetic metal and nonmetal mines heavy floating concentrates and cement industry slime clay and coal industry and so on. It is characterized by high productivity easy to operate. Rotary drum dryer is a horizontal rotating cylinder barrel its internal front to back welded angle different kinds of staggered copy board kiln body inlaid with different models according to demand firebrick in order to prevent back feed end material has a door ring and spiral copy board. With a reasonable structure well-made high output low energy consumption and easy operation.
Scope of LDHM Rotary Dryer:
Rotary drum dryer is mainly used in chemical metallurgy building materials mining and other industries granules powder drying.
Classification of LDHM Rotary Dryer:
According to the drying medium and the heat transfer between the wet material into direct heat rotary drum dryer (drying medium in direct contact with the wet material to transfer heat) and indirect heat rotary drum dryer (drying heat required by the cylinder wall indirectly passed to the wet material) two kinds. Indirect heat transfer drum dryer inefficient and complex structure and other reasons rarely used not in this introduction.
Direct transfer drum dryer the drying medium and the material according to the direction of flow downstream and upstream is divided into two kinds.
Direct heat transfer drum dryer main part of a slightly inclined to the horizontal rotating cylinder. Cylinder by a gear transmission speed is generally 2 ~ 6r/min the inclination of the cylinder on its length usually between 1 ~ 5 between. Material from a drum into the higher contact with hot air with the rotation of the cylinder the material flow under the effect of gravity lower end of the discharge is dried. As in the vacuum dryer working conditions feeding and discharge end seals are used to prevent air leakage.
The main technical parameter of LDHM Rotary Dryer:
Working principle of LDHM Rotary Dryer:
Dry and wet material from the belt conveyor or bucket elevator to the hopper and then pass through the feeding hopper feeder pipe into the feed end. Feeding pipe slope is greater than the material\'s natural inclination to the smooth flow of materials within the dryer. A dryer cylinder is slightly inclined to the horizontal rotating cylinder. Add material from the upper end the heating medium from the low-entry into countercurrent contact with the material but also with the heating body and the material and the flow into the cylinder. With the rotation of the cylinder by gravity material than the end of the run to the end. Wet material in the cylinder body to move forward the process either directly or indirectly got heat carrier to the heat so that the wet material to be dried and then in the discharge end of the belt conveyor or screw conveyor sent through. In the cylinder body wall with copy board its role is to put the material copied up and planted so that the contact surface of the material and increases airflow to improve the drying rate and to promote material progress. The heat transfer medium is generally divided into hot air flue gas. Heat carrier through the dryer after the general need within the gas cyclone trap material brought down. For further reduce exhaust gas dust content but also through the baghouse or wet dust collector and then put emissions.
Features of LDHM Rotary Dryer:
1 Multi-combined lifting device my company designed and manufactured dryer lifting device system in a wide range of technological innovations were made using a new multi-combined lifting device to overcome the traditional dryer the wind hole phenomenon high thermal efficiency reduce coal consumption by about 20%.
2 to use for a variety of burner: high boiling furnace furnace coal grinding powder and artificial increase coal stove.
3 Transmission gear size can be changed using the stud gear replacing the traditional steel gears cost savings investment but also greatly reduces maintenance costs and time.
4 using centralized control system enabling the central computer monitoring and management of large enterprises.
5 greater production capacity continuous operation;
6 simple structure easy to operate;
7 less failure low maintenance costs;
8 wide application you can use it dry and granular material for those large adhesion material is also very beneficial;
9 operating flexibility allowing the production of the product yield greater volatility range without affecting the quality of the product;
10 cleaning easy.
