Brief Introduction

Zenith’ belt conveyors are used as the backbone of bulk material conveying systems throughout the world. High reliability and low energy requirements make our belt conveyors the logical choice for moving material anywhere.The Belt conveyor manufactured by our company has the advantages of big conveying capacity, simple structure, convenient repair and standard parts, so it is widely used in the industries of mine, metallurgy and coal to convey loose materials and finished products. According to different technique requirements, the machine can convey material singly or be formed conveying system with other conveying equipment to meet different requirement of working line.

Product Features

The conveyor belt system can be used for horizontal transportation and slanting transportation very conveniently, so that it is widely used in all kinds of modern industrial companies, such as the under workings of mine, surface transportation system of the grass and open-pit quarry plant and ore beneficiation plant. The conveyor belt is pulled tight by the driving device, and the middle framework and roller composing the conveying belt as the pulling and bearing carrier, so that the bulk materials and pieces are continuously conveyed.

Working Principle

Material flowing over the belt may be weighed in transit using a beltweigher. Belts with regularly spaced partitions, known as elevator belts, are used for transporting loose materials up steep inclines. Belt Conveyors are used in self-unloading bulk freighters and in live bottom trucks. Conveyor technology is also used in conveyor transport such as moving sidewalks or escalators, as well as on many manufacturing assembly lines. Stores often have conveyor belts at the check-out counter to move shopping items. Ski areas also use conveyor belts to transport skiers up the hill.

Vibrating screen is multiplexed screw-type vibration transducer excitation arising work.Oscillator on the rotating weight of the sieve surface plane whirling vibration, and the lower rotating weight cone rotary vibration screen surface, the effect of the combined effects of the complex rotary-type vibration screen surface.Vibration trajectory is a complex space curve.The curve of a circular projection in a horizontal plane by an oval in the vertical plane of projection.Adjust exciting force, under the rotating weight, you can change the amplitude.On the adjustment under the weight of the spatial phase angle, can change the shape of the curve of the sieve surface trajectory to change the trajectory of the screen surface material.

Product Overview

The vibrating screen is suitable for the moist fine grade of difficult materials dry sieving vibration screening machinery and equipment, domestic processing difficult materials vibration screening machinery and equipment.Shaker with a large amplitude, vibration intensity, low frequency and the technological characteristics of the flexible screen surfaces.The course of their work, always maintain maximum opening rate, high efficiency, large capacity, sieve easy to replace, reduce the cost.The shaker the oversized screen surface and large processing capacity to meet the production needs of the site.Shaker sieve structure using multi-stage screen surface the vibration sieve box and the rack does not participate in the movement of the vibration, the sieve to achieve a large-scale.

Shaker advantages

Mainly by the sieve box, exciter, suspension (or support) devices and electric motors and other components.Electric shaker machine V-belt drive the exciter spindle rotation, due to the imbalance exciter weight of the centrifugal force of inertia, vibrating screen box.Change the eccentric weight exciter to obtain different amplitude.The main advantage of the shaker:

  • Due to the strong vibration of screen box, reducing the phenomenon of the material clogging the sieve, the sieve has a high screening efficiency and productivity.
  • Simple structure, easy removable screen surface.
  • Screening per ton of material consumed less power.

Working Principle

Vibrating screens, two motors synchronized reverse rotation of the exciter reverse excitation force, forcing the sieve screen driven longitudinal movement, so that the material on the exciting force periodically thrown forward a range thus completing the materials screening operations.Suitable quarry screening sand and gravel, but also for coal preparation, mineral processing, building materials, electricity and chemical industries for product classification purposes.

Shaker Face the shaker body constituted by a strand of the roll axis aligned transversely oscillating or vibrating in one plane.Their flat trajectory is divided into linear motion, circular motion, elliptical motion and complex motion.Shaking screen and shaker in this category.Vibrating screens, shaking screen Crank as transmission parts.Motor through a belt and pulley drives the eccentric shaft rotation, by means of a connecting rod so that the body for reciprocating movement along a certain direction.

Body perpendicular to the direction of movement of the centerline of the strut or the hanging rod, due to the oscillating motion of the body, to move to the discharge end of the sieve surface of the material to a certain speed, the material also be sieved.Shaking screen compared to the several sieve, higher productivity and screening efficiency.The disadvantage is that the driving force is poorly balanced.General concentrator rarely use it, and the more structured shaker.

Product overview

Vibrating feeder is widely used in mining, metallurgy, coal, building materials, light industry, chemical industry, electric power, food and other industries, to the massive, granular and powdered materials from storage silos or funnel uniform continuous or quantitatively to go to the affected device, such as crushing, filtering, screening, transportation, packaging machinery and other feed, and other ingredients.

Working Principle

Working principle of vibrating feeder: The machine produces centrifugal force through the rotation of eccentric block in the vibrator to make the screen compartments, vibrator and such movable part do forced circular or approximate circular movement continuously.The vibrating feeder by feeding trough body, exciter, spring bearing, gear, etc..Tank vibration feeder source of vibration exciter, the exciter is composed of two eccentric shafts (active and passive) and the composition of the gear pair, the driving shaft by the motor through V-belt drive, and then engaged by the drive shaft gear driven shaft rotation, active and passive the reverse rotation axis, tank vibration, so that a continuous flow of materials, the purpose of transportation of materials.

The advantages of equipment

  • smooth vibrating, reliable operation.
  • special trash rack designed to prevent material clogging.
  • rack adjustable gap.
  • wear parts.
  • to prevent wear parts wear small materials, small material, to increase production.
  • optional frequency conversion motor, adjust the frequency, thus changing the production, easy to control the feeding amount, without frequent start the motor.
  • starting frequency; (1) consider the entire production line, to ease broken jaw, back-breaking pressure; (2) to avoid frequent start high-power devices.
