Suitable Hot Air Furnace is very important for sand dryer machine. Only with suitable hot air furnace, the sand dryer machine can have biggercapacity, lower fuel consumption, high heat efficiency.

Sand Rotary Dryer is developed from rotary drum dryer. Sand Dryer machine usually hasthree drum sand rotary dryer ,two drum sand rotary dryer , single drum sand rotary dryer.

The traditional hot air furnace is produced when installation, it not only need to do much civil work such as cementfoundation,but alsoit will also cause much cost such as the salary of engineer and worker, the air ticket, the accomdation, etc. What is more, the traditional hot air furnace has a low heat efficiency about 60%, and the fuel such as coal can not be used sufficiently. It is a waste of fuel, and a lost for the users.

Dingli Machinery design one new type hot air furnace which is produced well at the factory.

Firstly, after the machines arrive at the user's factory, the useronly need to connect the hot air furnacewith the sand dryer machine. It will save much money and time for the users.

Secondly, The new typehot air furnace's heat efficiency is more than 75%, and the fuel can be burned sufficiently.

Thirdly, the hot air furnace has special dust and ash cleaning system. Inside the hot air furnace, most of the dust and ash is gathered in one room, and the user can clear the dust and ash every a certain time.
