Rotary kilns - externally heated / internally heated

Product parameters:

Externally heated rotary kiln

The materials of external heating rotary kiln are not in direct contact with flame and smoke, the heat source is between the heating furnace and the cylinder, and the materials are heated by heat transferring through the heat-resistant steel cylinder wall. The lining of heating furnace adopts all-fiber structure to achieve the effect of energy saving and consumption reduction. Small power consumption, smooth operation, less wearing parts, easy maintenance. According to the product characteristics of the reasonable design of the cylinder copy plate, spiral plate, scraper. At the feeding end and discharging end of the drum, the company's unique elastic sealing method is adopted, so that the sealing material is always sealed with the cylinder compression, avoiding the phenomenon of poor sealing in the traditional sealing method. The cylinder inclination angle is adjustable and the cylinder rotating speed adopts frequency conversion speed regulation, which can flexibly adjust the firing time and output of the products.

Internally heated rotary kiln

Internal heating rotary kiln is used for calcination of various materials, widely used in building materials, metallurgy, chemical industry, non-ferrous metals, sludge treatment, cement and other industries. The materials can be rolled and stirred along the tangential direction in the cylinder and move along the axial direction. It has the advantages of uniform heating, high thermal efficiency, continuous production, good quality of calcined products, site saving and high degree of mechanization. Solve the traditional tunnel kiln, push plate kiln, mesh belt kiln material heating is not uniform, burn impermeable, high energy consumption, long cycle and so on. Internal heating rotary kiln, high-temperature flue gas and products countercurrent, high heat utilization rate; cylinder inner wall masonry refractory bricks, head and tail hood lined with high-strength wear-resistant castables, head and tail hood and the cylinder is a flexible sealing, which can completely eliminate dust and material leakage.
