STRUCTURE

INTRODUCTION
Oil proppant kiln (Ceramic sand kiln) is the most ideal roasting equipment for oil proppant processing, and it is one of the most critical processes. Its main advantages are: large production capacity to control, maneuverability, suitable for a variety of ceramic sand roasting.Oil fracturing proppant, commonly known as oil proppant,ceramsite sand, is a ceramic particle products, has a high fracture strength. Oil fracturing proppant is mainly used for oilfield underground support to increase oil and gas production, are environmentally friendly products. This product uses high-quality bauxite, coal and so on. It is a substitute for medium and low strength proppant such as natural quartz sand, glass ball and metal ball. It can increase the output of stone oil and natural gas have a good effect.

In order to satisfy the domestic petroleum requirement, the petroleum exploitation industry develops rapidly, the related product also expanding rapidly. Hence, it promotes Chinese oil fracturing proppant industry continues development, and rotary kiln is the critical equipment for the oil fracturing proppant calcination. ZK rotary kiln is constantly optimize after discuss with many senior experts and refer experiences for many years. At present, ZK designed a series of oil fracturing proppant rotary kiln according to the industry demand.In view of the specificity of ceramsite sand, the rotary kiln developed and manufactured by our company, combined with the shortcomings in the actual production, continuously improve the products and make the products more perfect, thus effectively ensuring the roasting quality of oil proppant.

PROCESS
1. The rotary kiln has 2 to 4 supporting points (most of kiln has 3 points), which is ensure the support roller upper plane and tyre contact surface is parallel to the shell axis. There is a gap between tyre and shell which designed according to the expansion rate, then it guarantee to strengthen the shell by tight on the shell after thermal expansion.

2. The support device adopt rolling bearing to simplify the structure of support roller bearing, then it can reduce the power consumption during the kiln process and also improve the maintenance.

3. The driving system adopts adjustable motor with large scale, stable running and easy maintenance. The rotary kiln set a slow disk kiln structure, which is composed of diesel engine and reducer etc. It can running under power failure and convenient for kiln maintenance, the operation also simple and flexible.

4. The mechanical thrust roller and hydraulic roller are select by kiln model, the hydraulic thrust roller adopt domestic advanced technology of accurate plunger pump and speed control valve etc.

5. The kiln head and tail sealing adopt new technology of heat resistant steel scale, which instead of labyrinth sealing, not only reduce the air leakage of kiln head and tail, but also durable and easy replacement with low maintenance charge.
