The Working Principle:
Apron feeder is a kind of conveyor, which uses the link chain as the traction. The trough plate loading materials is set on the link chain. The sprocket wheel is set on the transmission shaft.  The transmission shaft and hollow shaft of reducer are linked together through the locking disk. The sprocket wheel is forced to run when the apron feeder operates. In general, the apron feeder is installed under the storage silo. When the link plate is running, the materials will continuously move to the trough plate of link chain. The purpose of conveying materials could be realized.
General Introduction:
The apron feeder is widely used in metallurgy, building materials, coal and chemical industry. The apron feeder has three series: heavy series, middle series, and light series. According to the strength of materials, working capacity of machine, the pressure of storage silo, and volume-weight of materials, we would choose the different series of apron feeder. In this way, the materials with multi-granularity and volume-weight could be transported to various receiving device. The main structures of apron feeder consists of actuating device, transmission shaft device, tensioning shaft device, thrust wheel, chain plate device and machine frame. 
 

Apron Feeder

The ball mill is the key equipment for the material crushing after it has been broken. Ball mills are widely used in cement, silicate products, new construction materials, refractories, fertilizers, black and non-ferrous metal beneficiation and glass ceramics, etc., and it is applicable to both dry and wet grinding of various ores and other abrasive materials.
The ball mill is composed of feeding part, discharging part, turning part and transmission part, etc. The hollow shaft uses steel castings, and the inner lining can be replaced. The big turning gear adopts the casting hobbing process, and the cylinder body is inlaid with a wear-resistant lining plate, which has good wear resistance. The machine runs smoothly and has reliable performance. According to the type of material and method of ore discharge, dry ball mill or wet grid type ball mill can be selected.
NHI has been dedicated to beneficiation technology research for many years, and is specializing in the production of various types of ball mill, including: ceramic ball mill, energy-saving ball mill, small ball mill, coal mill, rod mill, cement ball mill and so on. First-class production equipment, professional research and development technical team, to manufacture a first-class ball mill equipment for you! Mineral processing equipment experts with rich experience can also provide you with professional design technology of concentrator and configuration scheme of beneficiation equipment, NHI is your ideal choice!

External Meshing Involute Helical Gear Reducer

Mobile ship loader is the loading equipment berthing at one side of the dock and running along two parallel tracks. It is suitable for the loading operation of bulk materials at bulk cargo terminals or coal terminals. Mobile ship loader can handle ores, cement, coal, grain and other materials and apply to the bulk carriers from 3000 tons to 100,000 tons.
The ship loader produced by our company adopts three operation modes of semi-automatic control, manual control and on-side control and has high level automation. Frequency conversion and energy saving technology helps the ship loader save more energy. Our product has the advantages of advanced technology, perfect performance, reliable use, good stability, high loading efficiency, long service life, easy maintenance and so on. It can meet the needs of large capacity, high efficiency and frequent operations. Both noise and dust created are in line with the relevant standards of national environmental protection. Since telescopic boom structure is adopted for ship loader boom, swing radius of the boom is variable. The front end of the boom is equipped with a telescopic sleeve, and the sliding cylinder is composed of a cylinder body, a telescopic mechanism, a rotating mechanism and a throwing plate, and the cylinder body is composed of multiple sections. with the traction of the wire rope, the cylinder can be retracted to the shortest state, while the cylinder can be released under the gravity. The coordination between the sliding cylinder rotating device, elbow swing device, sliding cylinder swinging device and boom telescopic mechanism can satisfy the requirements of balanced loading, which is applicable to different ship types.
