How to choose the conveyor belt

Assembly line conveyor belt is the most expensive is the durability of the worst parts, conveyor operation in the process, the conveyor belt by a variety of different types and sizes of cutting load effects, will in the very complex stress state. The typical form of belt damage are the following: 1, by the effect caused by the impact of large ore tear, puncture and peel; 2 face layer and edge wear; 3, under the action of the environmental media, causing reduced strength index and aging; 4, core body through a piccolo and idlers of the stress caused by repeated bending fatigue. Conveyor belt costs about half the cost of all equipment. Thus, according to the conditions of use conveyors, choose the right conveyor belt, extending its life, and strengthen the operation and maintenance management, to improve conveyor efficiency, reduce production cost conveyor is important. http://www.prmindustry.com/
Abstract...Articles section General conveyor belt used with a rubber band and plastic two. Rubber band for the working environment temperature -10 ~ + 400C between the material temperature must not exceed +500 C. When the temperature exceeds 500C after the tape's elasticity begin to disappear, such as the temperature is too low, place tape on the hard crack. Temperature exceeds +900 C should be used when fire conveyor belt; temperature is below -15 ~-550C should be used cold conveyor belt.

 Conveyor based on the environment and requirements are divided into many different sizes and models: 1 according to the size of traffic divided by width: B500 B600 B650 B800 B1000 B1200 B1400 and other commonly used models (B on behalf of the width, in millimeters). 2 according to the different use of the environment is divided into ordinary rubber conveyor belt, heat-resistant rubber conveyor belt, rubber conveyor belt cold, acid and alkali rubber conveyor belt, oil resistant rubber conveyor belt, food conveyor belt and other models. Which ordinary rubber conveyor belt on the cover and food minimum thickness of plastic 3.0mm, plastic cover under the minimum 1.5mm; heat-resistant rubber conveyor belt, rubber conveyor belt cold, acid and alkali rubber conveyor belt, oil resistant rubber conveyor belt rubber cover on the minimum thickness of 4.5mm, the minimum under the plastic cover is 2.0mm. Depending on the specific circumstances of the environment to increase the thickness of 1.5mm can be up and down the plastic cover life. 3-layer fabric according to tensile strength conveyor belt into an ordinary canvas belt, canvas belt strength. Powerful type of canvas is divided into nylon conveyor belt (NN conveyor belt) and polyester conveyor belt (EP conveyor belt). 4, specification (1) with the core material: polyester-cotton fabric TC-70 cross-type, cotton canvas CC-56 type (2) Bandwidth: 100mm-1600mm (3) :1-10 layer fabric layer (4) plastic cover: face :1.5-9mm non-face: 0mm-4.5mm 1. plastic cover physical and mechanical properties: tensile strength coating performance levels ≥ Elongation ≥ Abrasion ≤ Mpa% mm3 H 24.0 450 120 D 18.0 400 100 L 15.0 350 200 2. full-thickness tensile properties: a. with the longitudinal tensile strength of not less than the following nominal values: 160,200,250,315,400,500,600,630,800 N / mm b. with full-thickness longitudinal elongation at break of not less than 10%. With reference to the full thickness of the longitudinal elongation force should not exceed 4%. c. linearity: not more than 25mm d. interlayer adhesion strength: Item ≥ cover cloth layer between the cover and the cloth layer thickness ≤ 1.5mm cover layer thickness> 1.5mm full sample average 3.2N/mm 2.1N/mm 2.7N/mm nylon conveyor belt (Nylon conveyor belt) Description: nylon conveyor belt with a belt of thin, high strength, impact resistance, good performance, interlayer adhesion strength, excellent flex and use long service life, suitable for long-distance, high load conditions, high-speed delivery of materials. 1 plastic cover mechanical properties: tensile strength coating performance levels ≥ Elongation ≥ Abrasion ≤ Mpa% mm3 H 24.0 450 120 D 18.0 400 100 L 15.0 350 200 2. Full-thickness tensile properties: a. with the longitudinal tensile strength of not less than the following nominal values: 160,200,250,315,400,500,600,630,800 N / mm b. with the full thickness of the longitudinal elongation at break of not less than 10% . With reference to the full thickness of the longitudinal elongation force should not exceed 4%. c. linearity: not more than 25mm d. interlayer adhesion strength: Item ≥ cover cloth layer between the cover and the cloth layer thickness ≤ 1.5mm cover layer thickness> 1.5mm full sample average 3.2N/mm 2.1N/mm 2.7N/mm according to user requirements, with a ring made of, plastic cover can be made into pits, herringbone, stripes and other patterns. 3, the performance of different varieties under the plastic cover is divided into common type, heat resistant, flame retardant type, cold type, acid type, oil type. 4, specification (1) with a core material: NN100, NN150, NN200, NN300, NN400 (2) Bandwidth: 100mm-1600mm (3) :2-8 layer fabric layer (4) plastic cover: face :1.5-8mm non- face: 0mm-4.5mm core selection of the product with cotton canvas, polyester canvas as skeleton material, the cushion rubber glue covered the use of good heat resistance or oxidation of small stupid rubber butyl rubber. The new product can be below the temperature at 120 ℃ under normal use for transportation temperature below 120 ℃ materials. Widely used in cement, coking, metallurgy, steel and other industrial uses.
