Small Scale Mobile Jaw Crusher for Startup BusinessSmall Scale Mobile Jaw Crusher for Startup Business We have just finished the production of a mini mobile jaw crusher with capacity 10-20 tons per hour. This jaw crusher is customized for one of our clients from Mindanao, Philippines. It is also equipped with a 2 deck mini vibrating screen (mesh 10mm/5mm) to help client get 0-5mm sand, 5-10mm and 10-20mm gravel. For easy moving, it is made to be wheeled (also can be a fixed jaw crusher as per client request). This small jaw crusher is a very good choice for users who have small scale crushing business to supply and and aggregate. Its power can be diesel engine or electrical motor as per needs.
Symons cone crusher is commonly used for secondary, tertiary or even quaternary crushing in static and mobile crusher plant. Generally speaking, It has different crushing chambers like standard & short head style to meet different needs. In China, it is also called high-efficiency cone crusher or compound cone crusher. It is a modern high-performance cone crusher designed and developed based on the principle of lamination crushing and the concept of more-crushing and less-grinding according to customer needs, which integrates high swing frequency, optimized crushing chamber shape and reasonable stroke. Practice has proved that this high-efficiency Symons cone crusher has won the trust of global users with its excellent performance, reliable quality and cost-efficient operation cost.2021.11.23
200TPH Stationary Screening Plant for Philippines Clients Unique Group will deliver a set of Stationary Screening Plant with capacity 200 tons per hour for one of our Philippines clients soon. The material that will be processed is river quarried material which includes mainly apple size pebbles and sand. After screening, user will have 0-5mm washed sand, 5-10mm, 10--19mm & 19-38mm gravel for construction use. Screening plant is suitable for river stone quarry plant to separate not big size pebbles and natural sand.2021.11.15
What should I do if the vibrating screen has a small amplitude and low screening efficiency? How to adjust the amplitude? Amplitude is an important factor that affects the screening efficiency of the vibrating screen. Users can control the speed of screening by adjusting the vibrating screen amplitude. How to adjust? What should I do if the amplitude is small, and what caused it? 1. Insufficient power supply voltage The vibrating screen is designed according to 380V three-phase electricity. If the line is not connected according to the regulations, the voltage is insufficient, which will cause the vibrating screen to have a small amplitude. 2. Too few eccentric block By increasing or decreasing the number of eccentric blocks and controlling the amplitude, you can try to increase the number of eccentric blocks to increase the amplitude. 3. The included angle of the eccentric block is too small If the vibrating screen is equipped with a vibrating motor, the angle between the eccentric blocks at both ends of the motor shaft will also affect the amplitude. The angle becomes smaller, the exciting force becomes larger, and the amplitude becomes larger. Otherwise, the amplitude becomes smaller, so you can change the angle by changing the angle to adjust the amplitude. 4. Large feed volume and large accumulation If the stone material transported to the screen surface at one time exceeds its bearing range, the remaining material or accumulation in the screen surface and under-screen hopper will be too much, which will increase the equipment load and affect the amplitude. At this time, it is necessary to stop the machine first, reduce the material on the screen to the normal range, and then start. In addition, the particle size of the material is directly related to the calculation result of the vibrating screen amplitude 5. Unreasonable spring design We know that the vibrating screen is mainly composed of vibrators, screen boxes, supporting devices, transmission devices, etc. The spring is an important part of the supporting device, so when designing the spring, the net variable of the spring should be smaller than the height of the device, otherwise, it will The vibrating screen's amplitude is too small; however, if the net variable of the spring is too large, it may cause the body to separate from the spring.2021.11.08
