Oil fracturing proppant rotary kiln

2.1 The kiln head end adopts a stainless steel retaining ring, and the front section is lined with high-strength refractory bricks, which effectively protects the cylinder of the rotary kiln;
2.2 The kiln head and kiln tail are sealed with fish scale steel sheets, which effectively reduces the heat loss;
2.3 Adopt frequency conversion speed regulation to stably control the speed. The final speed is 0.3-2rpm. The fire watcher can manually adjust the speed of the rotary kiln according to the kiln conditions and the thickness of the material layer to obtain reasonable working conditions, which creates favorable conditions for fire watching operations.
2.4 A large gear ring is fixed on the kiln shell and connected to the kiln shell through a tangential spring plate. This connection structure can leave enough heat dissipation space between the large gear ring and the kiln shell, and can reduce the influence of the bending deformation of the kiln shell on the meshing accuracy. It can also play a role in shock absorption and buffering, which is beneficial to extend the life of the kiln lining.
2.5 The stopper can be divided into two types according to its force and working principle: mechanical stopper and hydraulic stopper. Large rotary kilns mostly use hydraulic stopper to effectively regulate the movement of the kiln body.

● The frequency conversion technology is used to make the residence time of materials in the kiln easy to adjust;
● Elastic plate gear transmission and bearing support roller make the equipment run smoothly, reduce power consumption and improve equipment reliability;
● Combined scale seals are used at both ends, and double-pass seals are used at the joints to make the air leakage coefficient less than 8%;
● Use new refractory materials to reduce radiant heat loss;
● The drying and preheating kiln is equipped with a heat exchange device to reduce convection heat loss, greatly reducing the hot air temperature at the kiln tail;
● Support device: It adopts advanced spindle structure and is equipped with automatic temperature measuring device.
● Wheel stopper: It is divided into two categories: mechanical wheel stopper and hydraulic thrust wheel stopper. The hydraulic wheel stopper is equipped with an advanced hydraulic control system.
● Transmission device: single transmission or double transmission. The variable frequency speed motor controls the speed, which is reliable, energy-saving and efficient.
● PLC remote centralized control, easy operation and adjustment, safe and stable
