Materials are crushed and grinded by vibrating ball mill, and conveyed into storage bin, or into the feed port of conveyor directly.
Then conveyor will take the materials into the screening equipment. Now, let’s talk about some commonly used conveyors.
Spiral conveyor, vibrating feeder, bucket elevator, belt conveyor,
vertical elevator, etc. are commonly seen conveyors.
But the choice of a conveyor is decided by productive circumstances, the characteristics of materials, and the conveying amount. Most users will choose spiral conveyor, bucket elevator, vertical elevator, etc.
Bucket elevator is used to vertically lift crushed limestone, coal,
gypsum, clinker, dry clay granular material and raw material, cement,
coal and other powdered materials.
Bucket elevator, according to different running space, can be divided into three forms: Centrifugal discharge, gravity discharge and hybrid discharging.
The centrifugal bucket elevator runs faster, so it is suitable to transfer powder, granular, small block and other abrasive materials; the speed of discharge of the gravity bucket is slow, so it is suitable for bulk transport, a larger proportion , abrasive materials, such as limestone, clinker.
Bucket elevator traction member ring chain, plate chain and tape several.
Chain structure and manufacturing is relatively simple, and the connection of the hopper is also very strong, transporting abrasive material, the wear of the chain, but it is too heavy.
Plate chain structure is strong, light weight, applied to enhance the capacity of the hoist, but hinged joints susceptible to wear and tear, the tape of the structure is relatively simple, but not suitable for conveying abrasive materials, ordinary plastic materials, the temperature does not exceed 60 ° C, folders the Wire Rope tape allows the material temperature of 80 ° C, the heat-resistant tape allows the material temperature of 120 ° C, chain plate chain conveyor material temperatures up to 250 ° C.
Materials are sent to screening equipments by conveyor.
The commonly used screens include spiral vibrating screen, linear vibrating screen, ultrasonic vibrating screen, mining vibrating screen, etc.
The choice of vibrating screen is decided by the nature of materials, the amount of products, the aim of screen, etc.
Generally speaking, the whole equipments is a system, and any aspect should be taken into consideration, including the nature of materials, the assortment of equipment, the choice of vibrating mill, the choice of a suitable conveyor, and the specification of vibrating screen.
Only reasonable design can achieve the best effect.
