vibratory feeder

There are two eccentric shafts rotating at high speed at the same time from opposite directions, thus the strong centrifugal force is formed. The component forces of centrifugal force along the vibrating direction will always overlap each other, then counteract with that of vertical force from vibrating direction, then exciting force along single direction is formed to drive the feeder vibrate along straight line. When materials are fed into the feeder, they may be thrown up and move like para curve, then fall down. The materials will move forward on the slope surface of the feeder.

Circular Vibrating Screen

It adopts the structure of small amplitude, high frequency, large obliquity to make the screen hold the capability of high efficiency, large handling capacity, long life span, low consumption, little noise.

It uses eccentric block to produce strong exciting force.

It adopts tire coupling with capability of flexible connection and stable operation.

Crossbeam and the main body of the screen are connected with high strength screw bolts. So they have the features of simple structure and easy maintenance.

Portable Crushing Plant

Tyre portable crushing plant, equipped with PE series, PF series and HP series crusher of high efficiency, versatility, excellent quality, reasonable design and remarkable performance, which establish good reputation among domestic and overseas customer, mature in technology, simple and easy to maintain and operate, it has good adaptability and safe reliability in the traffic volume, granularity and corrosiveness

Flexible maneuverability

Tyre portable plants have high chassis, narrower body compared with other trucks, smaller turning radius, which mean they can be easily transported on highways and moved to crushing sites ,and this reduce the set-up time. This plant is more conducive to locate in the reasonable region of the crushing sites, which provides more flexible space and reasonable layout for the crushing process flow.

High efficiency and direct working

Incorporated portable crushing plant can be used independently, it can also supply more flexible applications to suit the business contractors’ special requirements according to the material type and required product sizes. It can achieve the most efficient transportation and lowest cost. Dependable performance and easy maintenance

Incorporate unit

This series plants incorporate all the crushing plants into one which eliminate the work to install the basic facilities in the bumpy ground when you use the independence crushing plants, reduce the cost of the material and man-hour. This reasonable and compact arrangement of the equipments improves the flexibility to set-up these machines.

Reduce the cost of transporting material

Tyre portable plant is able to achieve on-site crushing, avoid transporting material, which reduces the cost of transporting material for off-site crushing. In addition, the lengthened plant is able to transport the products to the motor-lorry directly, and then be carried away.

Mobile crusher

1. Mobile Crusher Application
　The Mobile Crusher (mobile crushing and screening plants) is applied to multistage crush large materials, and then screen the discharges according to their different specifications. The whole set plants is widely used to mine, building material, highway, rail way and hydropower industries, etc., finish crushing and screening operations at one time, produce required size and output for consumers.
2. Mobile Crusher Features and Benefits
　The Mobile Crusher (plants) has the advantage of reasonable matching, unobstructed discharge all line, reliable working, convenient operation, high efficiency and saving energy. Especially the mobility is very good, so it can extend with the raw material places or the construction place, and it can also make multiple matching, get to different product requirements.
3.Mobile Crusher Composition and working principle
　The Mobile Crusher (mobile crushing and screening plants) is composed of primary crushing and screening station and secondary one, belt conveyor, etc. Every crushing station is an independent working unit, they can respectively assume their different responsibility, and the belt conveyer is responsible for material transmitting and piling up between each crushing station.
