LSF Hydraulic Classifier

LSF hydraulic classifier is part of the family of hindered settling classification equipments. It adopts the mechanism of “layer flow high shear rate”, which solves the problem that traditional technology cannot adapt to the change of feed particle size, resulting in the loss of fine material recovery. LSF hydraulic classifier has significant advantages in terms of capacity, adaptability and efficiency, and has higher recovery and classification efficiency. LSF hydraulic classifier can be applied to aggregate processing, coal mud separation, quartz sand production, ceramic raw material processing, silica sand processing, and various metal mine tailings sorting and processing. Working principle LSF hydraulic classifier separates small particles based on differences in density or particle size. It combines a traditional fluidized bed separator with a set of parallel inclined plates that form a thin-film channel. Fine particle materials enter the interior of the thin-film chamber through the feed inlet, thus entering the mixing chamber located below the thin-film, where the material is fluidized to form a slurry under the action of the fluidized bed. Materials with high density will sink due to gravity, while materials with low density will float up. At the bottom of the mixing chamber, a higher density sediment solid bed is formed. The high density bed layer is kept in a suspended state by the fluidized water jet entering at the bottom of the chamber. Due to the turbulent motion generated by the fluidized water injected from below, coarse and fine low-density particles trapped in the dense fluidized bed are sorted and rise upward into the thin-film chamber above. High-density particles sink to the bottom of the fluidized bed under gravity and migrate to the gas cylinder at the bottom of the liquefaction chamber. The LSF can be remotely monitored and controlled by intelligent monitoring. When it reaches the set value, the control unloading device can be opened/closed by the control cylinder for unloading. Features 1. Customize according to specific on-site requirements; 2. Easy to transport and install; 3. Easy to adjust, flexible process, and higher efficiency; 4. Compact structure, easy to operate, suitable for any production line layout; 5. It can be remotely monitored and has a high degree of automation; 6. Reduce maintenance costs.

Banana screen

JR banana screen is suitable for screening, dehydration, medium, desliming, and other operations of coal, gravel aggregate, minerals, and other materials. This series adopts different screening areas, screen seam size, number of screen surface segments, and leaning angle of the screen according to the different uses and processing capacity of the screen. It is divided into single-layer and double-layer products. The working area is 5.7㎡~30.2㎡. There are 20 main specifications and models, which can meet the production needs of various types of mines and coal preparation plants. Structure  The Banana vibrating screen is mainly composed of a screen box, screen mesh, vibration exciter, vibration-damping spring, and lower seat frame. It uses a motor and an exciter as the vibration source. The exciter is mainly composed of an eccentric shaft, a pulley, a bearing, and a bearing seat. Connected to it, the motor drives the eccentric shaft to rotate, generating centrifugal inertial force, and forcing the screen box to vibrate. Technical Characteristics 1. Banana sieve has the characteristics of high screening efficiency and much higher processing capacity than a traditional grading screen and is an advanced screening machine. 2. Vibrator: Adopt the world's advanced JR type box vibrator, splash lubrication, and built-in lubricating oil channel in the box to ensure full lubrication of the bearing, the gear is a high-precision helical gear, the bearing is a special bearing for vibration equipment, and the oil drain plug With magnetic, external organic plastic transparent oil level, it is very convenient to observe the oil level, special measures are adopted to ensure that the bearings and gears work comfortably, the noise of the vibrator is less than 75 decibels, and the bearing temperature is less than 50 degrees. 3. The beam of the exciter adopts a three-I-shaped beam structure, which overcomes the problem of poor force in the middle of the square beam. It is equipped with reinforcing rib plates, which have high rigidity and lightweight, and can be treated with stress relief after welding. 4. The surface of the beam can be sprayed with a polyurethane protective layer, which is resistant to erosion, abrasion, and long life. 5. The shaped cutting and drilling of the side plate are completed by a high-precision CNC lathe to ensure the accuracy of the shape and drilling. There is no welding seam on the side plate to avoid stress concentration on the side plate, thereby preventing the…

Three-Axis Horizontal Screen

The three-axis horizontal screen is installed horizontally. The screening machine uses three sets of vibrators as excitation sources, and the motion trajectory of any point on the screening box is a linear ellipse. The material moves in a linear ellipse on the screening surface. Three-axis horizontal screen is suitable for dry and wet screening of coal, mining, and sand and gravel aggregates. It combines the advantages of circular vibrating screen that loose materials are not easily blocked, and linear vibrating screen that transports materials quickly and has a low center of gravity. Working principle The three-axis horizontal screen is composed of screen frame, spring, bottom frame, exciter, transmission device, motor, screen mesh, etc When the three-axis horizontal screen is working, the power is transmitted from the motor through a triangular belt to the driving shaft and gear vibrator of the exciter (with a speed ratio of 1), achieving the rotation of the three shafts at the same speed, generating excitation force. The exciter is connected to the screen box with high-strength bolts, resulting in elliptical motion. The material moves in a high-speed elliptical motion on the screen surface, quickly layering, passing through the screen, and moving forward to complete the classification of the material. Features 1.Small footprint, compact structure, and a processing capacity 70% higher than that of the same model of vibrating screen. 2.The vibration amplitude, frequency, and direction angle can be adjusted according to different needs. 3.The running trajectory of the screening machine is elliptical, with smooth movement and low power consumption. 4.The material screening is smooth, not easy to block holes, and has good screening performance.

Trommel Screen

The trommel screen is a screen that is curved into a cylinder. These trommel screens are also referred to as trommel drums or drum screeners. They are usually used to separate different grades of material such as soil, gravel, mulch, and sand by size. The trommel screen mainly consists of motor, reducer, drum device, frame, sealing cover and inlet and outlet. Working principle When trommel screens working, raw feed materials are picked up by the drum screens until it near drum top. Material then falls back down to the bottom of the drum by gravity. As it tumbles, the softer fractions broken down. The process repeat, smaller size materials pass throuth the screens while the larger size material pass through the opposite end outlet of the trommel drum, achieve accurate sizing and separation. Features 1. Adopting rolling conveying, the friction coefficient is small, and the sieve hole is not easy to clog. 2. The drum support adopts integral through-shaft structure, which runs smoothly, does not vibrate and has low noise. 3. The internal drum screen fittings are designed separately, which is simple in structure and convenient in replacement and maintenance. 4. The drum body adopts an effective fully sealed structure, without dust and pollution. 5. Safe and reliable operation, adopting deceleration drive, high transmission efficiency. 6. Customized screen, high screening efficiency, long service life and low maintenance cost. 7.Equipped with sprayer, proficient in both wet and dry applications.
