Selection principles of scraper chain

Scraper chain selection is mainly for the rational use of its structural type, chain pitch, blade pitch, scraper chain of materials and the like. In addition should be selected when the production capacity to meet the requirements, particular attention should scraper chain adaptability of the materials.

Scraper type often determines buried scraper conveyor conveying effect. The screed right choices, be satisfied with the delivery results; If you choose blade incorrectly can cause deterioration of conveying effect, can not even transport.
Type scraper blade choice is mainly to meet the conditions under the adaptability of materials, as far as possible to select the type of structure is relatively simple principle. Specifically selected, can be selected according to the material properties of the material viscosity, suspension and liquidity, machine groove width, conveyor layout and so on.

• pairs of conveying materials with better performance, giving priority to the use of a simple shape of the blade type, such as T-type, V-type, U-type; internal friction coefficient is small, the suspension is strong, mobility of materials should be used complex shape The blade, such as H-type.
• After delivery viscous or sticky larger absorbent materials, should adopt simple shape type, such as T-type, V-type, U-type, in order to reduce the material to adhere to the scraper, easy unloading and cleaning.
• delivery pressure knot strong chain or easily float material can be welded to prevent floating chain blade tilt.
• Machine groove width is smaller, the blade should use simple shapes. When transporting a bulk larger machine slot high density materials, in order to increase the rigidity of the blade, it can be used with a brace of O-type guillotine plate.
• buried scraper conveyor arranged horizontally (MS type), generally choose T, U-shaped or V-shaped blade; a vertical arrangement (MC type), generally V-shaped and U-selectable blade and are arranged for outward; Z-type arrangement (MA type), optional V-shaped blade, as introverted layout; buckle type arrangement (MK type), select V-shaped blade, as outgoing layout; flat annular arrangement (MP type), only You can choose L-shaped, outward arrangement; facade annular arrangement (ML type), optional V-shaped blade, as outgoing layout.
