Zhengzhou group of intellectual machinery of bucket elevator with a transmission capacity, high hoisting height, stable and reliable operation, long life and significant advantages. The hoist suitable for conveying powder, granular and non-small-block mill cut and a small mill cut materials, such as: coal, cement, stone, sand, clay, minerals, etc., because traction hoist is ring chain, thus allowing delivery of high temperature materials (material temperature does not exceed 250 ℃). General delivery height of up to 40 meters. 
 Bucket elevator main features: 
 1 drive power is small, the use of flow feeder, induced discharge, large capacity hopper-intensive layout in almost no time to enhance the return of materials and excavating material and, therefore, less reactive power. 

 (2) to enhance a wide range of these types of materials to enhance the machine, requires less features, not only can improve the general powder, granular materials, but also to enhance the mill cut larger materials. Tightness, less environmental pollution. 

 3 runs, good reliability, advanced design principles and processing methods, ensure the machine's reliability, trouble-free for more than 2 million hours. Lifting height high hoist running smoothly, so you can achieve a higher lift height. 

 4 long life, take elevator to feed into the style, without using bucket excavating, material and collisions between the rare phenomenon of squeezing. This machine was designed to ensure that the material in the feed, discharge, when few scattered, reducing mechanical wear. 

 Bucket elevator conveying works: 
 Hopper to the storage of materials from scoop below, with the belt or chain raised to the top, bypassing the flip down after the top round, bucket elevator to accept the material dumped into the tank. Belt bucket elevator drive belt generally use the rubber band, put the next or on top of the drive drum and drum on the bend below. Chain bucket elevator drive is generally equipped with two parallel transmission chain, or following a pair of drive sprocket, under or above the bend is a pair of sprockets. Bucket elevator are generally equipped with a chassis to prevent bucket elevator in the dust. 

 Bucket elevator installation: 
 1, bucket elevator must be firmly mounted on a solid concrete foundation. Base surface should be smooth and horizontal state to ensure the bucket elevator installed to reach the vertical requirements. Higher altitude of the bucket elevator casing and the upper part of the Department in which case the appropriate place to be and its adjacent buildings (such as silos, workshops, etc.) together to increase its stability. Installation to install the lower part, for the anchor bolt, then install the central cabinet, upper cabinet after security. Case a successful installation, calibration verticality. In line with the lead up and down the full height measurement, the error should be less than 10mm. Up and down the shaft should be parallel to the axis line should be in the same plane. Low height bucket elevator installation, you can put in the ground plane on the middle and lower case all connected and a more just, then the whole hanging straight on the basis of fixed in concrete. 
 2, the chassis is installed, install the chain and the hopper. U-shaped hopper with screw connection, both the chain joints, but also a hopper fixed parts. U-screws and tighten the nut must be reliable locking. 

 3, chain and hopper installed, proper tension. 
 4, for each gear and bearing oil and add the appropriate amount of butter. Industrial gear reducer with lubricating oil. Bearing in calcium or sodium with butter can be. 
 5, commissioning, installation should be empty after completion of commissioning. Air operation should be noted: not reversed, can not have bump phenomenon. Air operation is not less than 2 hours, there should be overheating, bearing temperature rise does not exceed 250C, the temperature rise of not more than gear 300C. Empty running 2 hours later, all the normal load test can be carried out. Trial run with a load of feed should be uniform to prevent feeding too much, resulting in lower congestion, "stuffy car." 
 Bucket elevator operation and maintenance considerations 
 1, bucket elevator car load should be empty. So every time before shutdown to drain all the material inside the hopper, and then stop. 
 2, can not be reversed. Reverse chain derailment phenomenon that may occur, excluding failure derailed a lot of trouble. 
 3, uniform feeding. Sudden increases the volume of feed ban. Feed amount can not exceed the transmission capacity hoist. Otherwise likely to cause severe accumulation of material at the bottom when "boring car" accident. 
 4, in a timely manner appropriate to add oil. 
 5, chain, and badly worn or damaged hopper should be promptly replaced.
