Features and functions of the special conveyor belt

With the rapid development of the financial, conveyor belt becomes more and more diversified, according to the technical comparison and different customer's requirements, please see the following opinions:

Acid and alkali resistant belt selects the cotton canvas, nylon canvas or polyester canvas as its core, belt body has a good elasticity and small elongation, it is easy to form a groove type. use. Selection of acid and alkali resistant materials polishing cover made of rubber, with good function of resistance to chemical erosion and good physical function. Used in contact with acid and alkali environment,such as phosphate fertilizer manufacturing, baysalt seawater. Acid and alkali resistant belt (acid and alkali resistant belt) rubber covering reference rubber plastic blending is adding alkaline material, excellent personality than neoprene acid-base belt resistance to acid and alkali resistant function better. Drum material referenced polyester canvas, more reliable than cotton canvas with acid core functions, easily made into a ring. And the ring-shaped belt is produced the ring belts process belts without joints, its core strength can reach the belt body of the joint office 90%, no significant joint belt surface faults, so belt moving flat with small elongation. Core references made of high quality cotton or cotton canvas.

Do you know the function of scraper on the belt conveyor?



Conveyor belt is the most commonly used material handling equipment, which is widely used in chemical, coal, iron & steel, metallurgy, mining industries, port, thermal power plant, etc. However, for conveyor belt which runs in the open air without cover hood, water scraper is a necessary accessory which is used to get rid of the stagnant water on the belt. 
Water scraper mainly consists of support & frame, idler sets, axle, bearing block, connecting rod, crank, electric-hydraulic pusher, etc. The operation precondition of water scraper is conveyor belt non-loading running. In the operation, press roller, trough carrier idler, flat carrier idler, connecting rod and crank are workings as a rotary body, the electric-hydraulic pusher drives the press roller and trough carrier idlers in clockwise rotation, then the top of trough carrier idlers and flat carrier idlers are on the same tangent plane. Under the clamping pressure of press roller and carrier idlers, the belt is lifted up, and the water is discharged from both sides of the conveyor belt. Thus the shift between normal operation and water removal can be achieved through the rotation of rotary body. When the conveyor belt is in normal operation, the trough carrier idlers of water scraper are used as the part of conveyor belt, so the belt can passes through the water scraper smoothly.This kind of water scraper has simple and reliable structure, which can avoid the belt damage. And it has the features such as safe and reliable operation, long service life, easy installation and convenient maintenance. 


From now on, you may have a good learn about the water scraper, and many more knowledge in www.pkmachinery.com, please check.
