SKB Gear since its establishment, the enterprise development year by year, product including the 900mm diameter of the large kiln gear constantly updated, and with advanced processing equipment, exquisite technology, strict testing, to ensure to provide customers with excellent products, products are exported to all over the country and abroad.
Kiln is the kiln body portion (rotary kiln) of the body, usually from 30 to 150 meters long, cylindrical, the middle of three to five roll laps. Multi-cylinder factory processed into 3 to 10 segments, transported by truck to the destination of large welded. Which is also known as rolling circle portion (rim) cast from molten steel, roller bearing ring portion of the kiln due to the plate so slightly thicker than the rest of the kiln. Part of the rolling ring and the support tugboat, also connected to the corresponding kiln foundations, load-bearing pillar of the entire rotary kiln. Usually a group of rollers, two by two idler gear wheels and components. Kiln during normal operation to be covered with bricks inside.
The products of SKB Gear took the lead through the ISO9001:2000 international quality system certification and CE certification, the main parts and wearing parts adopt high quality wear-resistant materials and advanced processing technology, makes the equipment insisted of the 900mm diameter of the large kiln gear excellent durability, continuously meet the needs of the broad masses of customers at home and abroad.
