Just like changing a car8217s oil is necessary for smooth operation, preventative maintenance can help operations avoid unplanned breakages and downtime. As a key part of almost any processing operation, vibrating screens deserve special attention. Watching and listening for problems and routine maintenance are just a few ways to keep things running smoothly.

Another mechanical classifier is the spiral classifier. The spiral classifier such as the Akins classifier consists of a semi-cylindrical trough a trough which is semicircular in cross-section inclined to the horizontal. The trough is provided with a slow-rotating spiral conveyor and a liquid overflow at the lower end. The spiral conveyor moves the solids which settle to the bottom upward toward the top of the trough.
Slurry is fed continuously near the middle of the trough. The slurry feed rate is so adjusted that fines do not have time to settle and are carried out with the overflow .liquid. Heavy particles have time to settle, they settle to the bottom of the trough and the spiral conveyor moves the settled solids upward along the floor of the trough toward the top of the troughthe sand product discharge chute.
Rake and spiral classifiers are used for close-circuit grinding.

Spiral classifier is also called screw classifier. The spiral classifier is widely used in the beneficiation plant to form a closed loop with the ball mill to split the ore or to classify the ore and fine mud, grade the slurry during the spiral classifier mineral processing, and dewater in washing operations.
The spiral classifier belongs to the beneficiation equipment. It is mainly composed of a transmission device, a spiral body, a trough body, a lifting mechanism, a lower bearing bearing bush and a discharge valve. The spiral classifier can process the material like gold, sand, etc. Since the specific gravity of solid particles is different, the rate of precipitation in the liquid is different. The spiral classifier is used to treat alluvial sand ore, especially suitable for useful minerals.
Applied Materials Iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, tungsten, tin, tantalum, niobium, copper, zinc, lead, gold, etc.
The spiral classifier works by virtue of the principle that the size and specific gravity of solid particles are different, so the sedimentation rate in liquid is different. Fine ore particles float in the water and overflow, while coarse ore particles sink at the bottom of the tank and are discharged by spiraling upward to perform mechanical classification. It can filter out the material, and then use spiral sheet to screw the coarse material into the feed port of the mill, and discharge the fine material from the overflow pipe.
The base is made of channel steel and the body is welded with steel plate. The screw shaft has a water inlet head, a shaft head and a pig iron sleeve, which are wear-resistant and durable. Lifting device is divided into electric and manual. Spiral Classifier structure grader is mainly composed of transmission device, screw, groove, lifting mechanism, lower support bearing bush and discharge valve.
In order to ensure efficient and continuous operation of the equipment, not only the equipment maintenance is required in the later stage of the operation, but also the inspection work in the early stage is indispensable. Fote Spiral classifier manufacturer list a few points for users for reference

Spiral classifier is one of classic mineral processing equipment in the classification of equipments, which shall be mainly applied for pre-grading and inspecting-grading in the circuit of grinding, and washing, removing mud and other operating Spiral classifier is the equipment that grading materials according to the settlement of particles
Spiral classifer for ores upgrading,mineral processing,beneficiation 1 Structure of Spiral classifier We produce high weir type, single and double spiral, and immersed single and double spiral classifiers The seat of the machine features channel steel material, while the body is armor plated and the spiral axle is made of cast iron for.
Spiral Classifier Separator For Mineral Gravity Separation. The motion of the spiral creates Pool Hindered Settling in the bottom pool area, where the agitation of the water hinder the fines from settling to the bottom, but the coarser particles do settle and are carried up the slope by the revolving spiral, to the discharge, located at the top of the classifier.
spiral classifier for mineral processing plant for . Spiral Classifier goldcilplant. Spiral Classifier. Spiral Classifier is a traditional type of classification equipment, mainly for metal mineral processing for the slurry density and particle size on the wet grade, mining operations could also be used in
spiral-classifier Application. In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesnt lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do.
Applied material iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, tungsten, tin, tantalum, niobium, etc
According to the number of spiral, spiral classifier can be divided into single spiral classifier and double spiral classifier according to the submerged overflow surface depth of spiral blade, it can be divided into high weir type and submerged types.
Spiral classifier is widely used in mineral processing plant to form closed cycle way with ball mill for split mineral sand, or used in gravity concentrator to grade ore and fine mud, or the size grading of slurry in ore dressing process as well as desliming, dehydration and other operations in ore washing operations. It has the characteristics of simple structure, reliable work, convenient operation, etc.
The mineral separation spiral classifier is used in the dressing plant to match with the ball mill to distribute the ore sand, or in the gravity dressing plant to classify the ore and mud. The particle size classification of the slurry in the metal beneficiation process and the desilting and dewatering of the washing Wait for homework. This machine has the characteristics of simple structure, reliable work and convenient operation.
The base of the machine is made of channel steel, and the body is welded with steel plates. The water inlet head and shaft head of the spiral shaft are made of cast iron, which is wear-resistant and durable.
High weir type the top of the spiral blade at the overflow end is higher than the overflow surface, and the spiral center of the overflow end is lower than the overflow surface. Mainly used for ore classification with an overflow particle size of 0.83-0.15mmSubmerged The spiral blades at the overflow end are all submerged below the overflow surface. Mainly suitable for ore classification with overflow particle size of 0.15-0.07mm.
