Spiral Chute

The spiral chute is a mineral processing device that creates a centrifugal flow film on its inclined spiral surface, leveraging differences in specific gravity, particle size, and shape between valuable minerals and gangue. Within the combined force field of gravity and centrifugal force, separation is achieved by exploiting the varying gravitational forces, hydrodynamic pressures, and frictional resistances acting on different particles. Spiral chutes are ideal for processing fine-grained iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, phosphorite, tungsten ore, tin ore, tantalum ore, and niobium ore with particle sizes ranging from 0.3 to 0.02 millimeters, as well as other non-ferrous metals, rare metals, and non-gold minerals with differing densities. Working Principle The spiral chute is primarily composed of six components: a feed distributor, a feed trough, a spiral trough, a concentrate discharge trough, a receiving hopper, and a support frame. When slurry of a specific concentration is fed into the upper section of the spiral separator, it rotates downward along the spiral trough. Coarser ore particles settle first at the bottom of the trough, while finer particles flow in the upper layer of the slurry. Due to the differing trajectories of ore particles with varying densities within the chute, particles of different densities can be intercepted at distinct positions along the spiral, achieving effective separation. Additionally, the water flow dynamics within the spiral chute facilitate material mixing and uniform distribution, thereby enhancing mineral processing efficiency. Features 1. The end of the spiral chute separately intercepts fine concentrates, middlings, and tailings. 2. No flushing water is added during the selection process. 3. Spiral blades are constructed from fiberglass, offering lightweight strength and durability. 4. Spiral chutes feature high processing capacity, simple structure, and low operating costs.

Silica Scrubbing Machine

LZZG silica scrubbing machine features an efficient impeller design that precisely controls turbulence to achieve effective attrition scrubbing. It maximizes the removal of surface films, coatings, and slimes without reducing particle size. The incoming materials undergo multiple washing cycles to ensure optimal cleaning performance, significantly enhancing product value and increasing the recovery rate of viable material. The LZZG silica scrubbing machine is primarily used for processing glass sand, fracturing sand, ore, clay, iron ore, and other products with stringent requirements for color and turbidity. Working principle During operation, mixed materials first enter the scrubbing unit for thorough friction and washing. Two opposed shaft-mounted turbine impellers generate counter-flowing slurry, creating high-impact collisions between particles. The ideal solid concentration ranges from 70% to 80%, depending on the specific mineral characteristics. Multiple friction units can be connected in series based on material properties. Scrubbed overflow materials then enter the impeller sand washer for secondary cleaning, after which the washed clean materials proceed to the dehydration area. Typically, hydrocyclones are also employed to recover fine materials from the overflow, maximizing overall yield and benefits. Features 1. Simple equipment structure and small floor area; 2. Efficient impeller design, high washing efficiency; 3. Multiple cleaning, good product turbidity and high product quality; 4. Use the interaction between particles to scrub and decompose mud and reduce equipment wear; 5. Maximize the recovery rate.

LZ Sand Washing & Recycling Machine

The LZ Sand Washing & Recycling Machine is engineered based on a sand washer and sand recycling system, incorporating advanced international technology. Key components include the XSD wheel sand washer, high-frequency dewatering screen, high-pressure cyclone, cleaning tank, return box, high-pressure wear-resistant slurry pump, motors, and more. This machine features a simple structure with multiple functions and is widely used for washing, screening, recycling, and dewatering crushed sand, river sand, lake sand, or sea sand. Working Principle *Washing: The bucket is driven by the motor through the reducer and rotates in a circle. It features numerous sand storage web grooves and a bucket screen for sand retention and primary dewatering. As the bucket moves, sand is discharged from the storage web grooves after being cleaned in the cleaning tank and primarily dewatered on the bucket screen. *Recycling: Slurry water is extracted by the slurry pump, and fine sand is collected via the centrifugal force of the cyclone before being fed onto the polyurethane screen from the apex spray. Fine sand (0.16-3mm) and water are efficiently separated using the vibration screen. *Dewatering: Coarse sand (3-10mm) and fine sand (0.16-3mm) are fed onto pol vibrating screen for dewatering. Features 1. Higher sand quality with lower moisture content. 2. Recovers fine sand in the 0.16–3mm range, resulting in lower mud content. 3. Compact structure for easy installation. 4. High productivity, enabling the recovery of up to 95% of fine particles in the material. 5. Solves cleaning issues in sedimentation tanks while improving economic performance.

Crawler Type Wash Plant

The Crawler Type Wash Plant achieves mobile washing operations via its crawler chassis, offering greater operational flexibility. It is powered by diesel and electricity, allowing for either external power supply or standalone diesel operation. The double-washing process ensures excellent sand cleaning performance, effectively handling materials with high mud content. Additionally, it recycles wastewater to achieve a high resource utilization rate. The unit can be equipped with satellite positioning and lock functions, supporting various commercial sales models and cooperation forms. This mobile plant features advanced technology, intelligent monitoring, and a control system capable of wireless remote monitoring, data transmission, data analysis, and remote control.   Structures It is primarily composed of a power system, a travel system, a hydraulic drive and steering system, a working system, and a control system. It can also be equipped with remote positioning and locking, fault monitoring, data collection, wireless remote control, and other auxiliary systems. Key components include the crawler device, hydraulic motor, planetary reducer, generator set (comprising an engine and generator), hydraulic workstation, control cabinet, frame, working device (spiral sand washing + wheel sand washing + fine sand recovery + dehydration), working platform, remote control unit, and optional satellite positioning mechanism, information monitoring, and data transmission systems. Working Principle Screened quality sand is fed into a spiral washing tank via a chute for primary washing. The spiral classifier rotates to tumble and grind the material, effectively removing impurities from the surface of the sand. The washed sand is conveyed by the blades into the bucket wheel sand washer. Mud water and low-density materials are removed and pumped to a desander cyclone for recycling, then also fed back into the bucket wheel sand washer. As the buckets rotate, the sand is cleaned in the bucket wheel sand washer. The clean sand is then discharged onto a polyurethane screen for dewatering. Simultaneously, the mixture of mud water and fine particles is extracted to a secondary desander cyclone to recover fine sand, which is subsequently fed onto the polyurethane screen for dewatering. Finally, the fully dehydrated product from the high-frequency vibrating screen is transported to the stockpile via belt conveyor. Features 1. Dual power supply options: diesel and electric. When grid electricity is available, the unit operates on electric power; in remote locations without electricity, it runs on a diesel generator set. 2. Enhanced operational flexibility enabling rapid relocation. Unlike traditional wheeled mobile sand washing plants, this…
