Transportation machinery by the use of zoning can be divided into
1, bulk material handling machinery (eg: belt \ Screw \ bucket promotion machine \ inclined conveyor)
(A) by a conveyor belt tensioning device drives the central structure and composition of the roller conveyor as towing and carrying member, so as to continuously fed into pieces
scattered and fragmentary materials or goods.check weighers
Friction drive conveyor is a continuous manner for material transport machinery. Apply it, the material can be transported in a certain line, from the initial feed point to the
ultimate discharge point between the formation of a material transfer processes. It can be granular material transport can also be carried into the delivery of items. In
addition to the purely material handling, but also with various industrial enterprises in the production process of matching the requirements of the process, the formation of
the rhythmic flow homework transport line. So conveyor is widely used in various industrial enterprises in the modern.
In the underground mine workings, mine ground transportation systems, open pit and processing plant, widely applied conveyor. It is used for horizontal transport or inclined
Universal conveyor from the conveyor belt, roller, roller and the drive, brakes, tension, bend, loading, unloading, cleaning and other equipment components.spiral conveyor
Commonly used with two kinds of rubber bands and plastic. Rubber band together for the working environment temperature -15 ~ 40 ° C between. Material temperature does not
exceed 50 ° C. Upward transport of Granules inclination 12 ° ~ 24 °. Available for large transmission angle tread rubber band. Plastic belt with oil, acid, alkali and other
strengths, but for the weather and poor adaptability, easy to slip and aging. Bandwidth is the main technical parameters of belt conveyor.
Of single drum (tape on the drum wrap angle of 210 ° ~ 230 °), double drum (wrap angle of 350 °) and multi-cylinder (for power) and so on. There trough roller, flat-shaped
roller, spherical roller, buffer roller. Trough roller (2 to 5 by the roller composition) supporting bearing branches for conveying granular materials; aligning roller to adjust
the lateral position with, to avoid deviation; buffer roller mounted in place by the material to reduce the impact of material on the belt.
Minute drive rollers and bend pulley. Drive rollers are main components of power transmission. Of single drum (tape on the drum wrap angle of 210 ° ~ 230 °), double drum (wrap
angle of 350 °) and multi-cylinder (for power) and so on.
④ tensioning device
Its role is to achieve the necessary belt tension to avoid slipping on the drive roller and make conveyor belt between the deflection rollers ensures delineated range.
Belt edge technology
The first is its reliable operation. Require continuous operation in many important production units, such as the transport of coal power plants, steel mills and cement
conveying bulk materials, as well as loading and unloading of ships in ports all adopts belt conveyor. If the shutdown these occasions, the loss is great. If necessary, take a
class to a group of belt conveyor can work continuously.
Conveyor low power consumption. Because the material almost no relative movement of the conveyor belt, not only the running resistance (about 1/3-1/5 scraper conveyor), but also
the wear and broken cargo are small, production rate. These are conducive to lower production costs.
Conveyor belt conveyor line adaptable and flexible. Line length according to need. Short as a few meters, length up to 10km or more. Can be installed in a small tunnel, the
ground transportation can also be set up in the region over the chaos and danger.
According to the process requirements, the performance is very flexible conveyor belt from a point or points by the material. Also provide multiple discharge points or several
sections. When simultaneously at several points on the conveyor belt feeding (eg Coal bunker under the conveyor) or along the longitudinal direction of the belt conveyor at any
point by averaging feeding equipment to feed conveyor, the belt conveyor machine has become a major transport route.
Coal stockpile conveyor can stockpile reclaimer roadway below, when necessary, but also to the heap of different materials are mixed. Simple materials can be discharged from the
head of the conveyor, but also by moving plow unloader or unloading vehicle longitudinal direction of the belt at any point of discharge.
(2) commonly known as the auger screw conveyor, granular or powdered materials together for the horizontal conveyor, inclined conveyor, vertical transportation and other forms.
Delivery interval varies according to deformity, usually from 2 meters to 70 meters.
Conveying principle: rotating spiral blade for screw conveyor passage of the material transported. So that the material does not rotate together with the screw conveyor blades
is the material force of its own weight and the frictional resistance of the material conveyor chassis.
Features: Screw rotating shaft is welded spiral blades, blade face delivery of materials based on a solid surface different type, belt type face, leaves and other types of face.
Screw conveyor screw axis in the direction of movement of the material with the thrust bearing to the terminal with the material to spiral axial reaction force, the captain
longer, should be added to intermediate suspension bearings.
Two screw conveyor is to have two rotating blades were welded with the rotary shaft screw conveyor. To put it plainly, is to two conveyor organic combination, consisting of a
Screw rotation axis of rotation, determines the conveying direction of the material, but generally in the design of the screw conveyor are transported in accordance with the
individual blades of rotation. When the reverse transport, it will greatly reduce the service life of the conveyor.
(3) Bucket promotion machine using the average fixed on a series of undue traction member hopper, vertical continuous promotion materials handling machinery.
Bucket promotion with throughput, highly promoted high, stable and reliable, long life obvious strengths, and its main functions and parameters in line JB3926 ---- 85 "vertical
bucket promotion machine" (the scale equivalent reference to international standards and abroad to improve their predecessors scale), the traction ring chain compliance MT36
---- 80 "Mining High intensity ring chain", the promotion machine is suitable for conveying powder, granular and small block of non-abrasive and abrasive of small materials,
such as: coal, cement, stone, sand, clay, ore, etc., because the traction is promoted ring chain, thus promised delivery of high temperature materials (material temperature does
not exceed 250 ℃). General transport height of up to 40 meters.
