The electric motor runs slowly with the impeller after decelerated by the belt, decelerator and gears wheel. The sand and stone flow into washing launder from feeding launder, rolling with the impeller, and grinding with each other. The impurity covering the sand is washing away. Adding more water at the same time, the strong water flow will take away waste and some low-weight wastes from washing launder. The above is the whole washing process.The clean sand and stone is lift up by vane. When it goes up slowly, the water begins to drop through the mesh and fall back into the washing launder. On one hand, water is removed from the sand and stone; on the other hand, the water can be fully used. Finally, the sand and stone goes to the out launder from the rotary impeller to finish the washing task
Step2: dewateringQualified sand is shoveled to the dewatering screen directly. This dewatering screen sieve is made of PU polyurethane material which has characters such as no blocking, high temperature resistance, and excellent corrosion resistance, then wet sand moisture can be highly reduced after dewatering.Step3: recyclingWaste sand water is extracted by slurry pump into high pressure sediment separator, fine sand is sprayed onto polyurethane screen also for de-watering, the waste water flows back to return box and then flows out
1. Simple structure, stable performance. Long service life of the bearings.2. Little loss for medium-sized or fine sand and stone powder.3. Parts constructed for durability. Easy maintenance.4. Longer working life, applicable to multiple working environments

Commonly used beneficiation methods include gravity separation, flotation, magnetic separation, electrical separation and chemical beneficiation. Even the same type of copper ore, it is necessary to design the most appropriate process according to local conditions, and cannot be copied completely
➤Crushing: cone crusher, improved cone crusher and high-pressure grinding roller (HPGR).➤Waste classification: NIR (near infrared) classification, optical (color) classification, XRF (X-ray fluorescence)➤Concentration is performed by combining dense medium separation (DMS) with XRT (transmitted X-ray), pulsed X-ray, mineral jigs according to application and condition.➤Using conventional X-ray technology, pulsed X-ray technology or XRT for the final recovery of diamonds
Processing of diamond ores begins with crushing. Typically, an ore is crushed initially to below 250 mm by means of a gyratory crusher and then to 75 mm using a cone crusher. The final stage of crushing is done by means of a high-pressure roller mill to further reduce the size below 25 mm. The incremental size reduction is helpful for minimizing the possibility of breaking diamonds inadvertently. The crushed ore is scrubbed in a tumbler in the presence of water, while the fines generated during crushing and scrubbing are removed by screening typically at 2 mm. The crushed ore in the range of 2–25 mm size is sent to heavy-media cyclones, with the diamond-rich underflows going to X-ray sorters to recover diamonds. The reject streams from the X-ray sorters are then sent to grease tables (or belts), in which diamonds are retained on the grease table as they are selectively attracted to the grease via hydrophobic interaction while hydrophilic gangue minerals flow through
In most cases, the materials smaller than 2 mm are disposed of without further processing due to the lack of appropriate separation methods. In some plants, the 2 mm material is screened at 0.5 mm, and the 2 + 0.5 mm fraction is subjected to flotation.However, it has been a challenge to recover small diamonds by flotation for two reasons. One is the difficulty in floating diamonds as large as 2 mm using conventional flotation machines. In general, mineral flotation is effective in the narrow particle size range of 0.1–0.25 mm. The other is that the dissolved species present in the aqueous phase of kimberlite ore slurry tends to reduce the hydrophobicity of diamonds, while the flotation of coarse particles requires stronger collectors that can increase the hydrophobicity beyond the level that is required for the flotation of smaller particles
A horizontal rotating cylindrical drum with internal lifters that continuously abrade material under controlled water to ore ratios. Not applicable for plastic type clays, as these can pelletize through the tumbling action
Disagglomeration for clay removal Abrasion resistant paddles affixed to a horizontally mounted rotating shaft yields an aggressive washing action that breaks down clay, it is more applicable to tough plastic type clays
The second most fundamental of the emission reduction strategy lies in a wide range of behavioral changes. Achieving successful emissions reductions will ultimately require consumer and investor demand to shift to low-carbon energy resources. Carbon pricing incentives can promote behavioral change, but price factors alone cannot reduce the scale and speed of emissions to the required level. Governments play a key role in encouraging change in behavior and transforming low-carbon economies. Policy tools include setting standards, providing information, encouraging research and development, and restricting decisions that are not conducive to climate change when necessary. International cooperation is the third fundamental…
Ball mill is key equipment for crushing materials after being crushed. It is suitable for cement, silicate products, new building materials, refractory materials, fertilizers, nonferrous metal beneficiation, and glass-ceramics. So, when the ball mill is selected to grind the material, how to choose the dry grinding ball mill and wet grinding ball mill? Let’s look at the following:
On Monday, October 21, Henan Fote Heavy Industry Machinery Co., Ltd. officially released a new equipment — sand washing machine. These include a single-wheel sand washing machine, a double-wheel sand washing machine, and a three-wheel washing machine
The sand washing machine is also called a sand washer machine or stone washer machine. It is a kind of artificial sand washing equipment usually used in sand making line. Sand washer machine plays a key part in cleaning crushed stone like quartz, granite, marble, pebble, andesite, dolomite, silica and so on
Heat dissipation is a large number of mechanical equipment, which must pay attention to and solve the problem. As small as computers and mobile phones; as large as airplanes and automobiles, and then to various mechanical equipment, “heat dissipation problems” are spread all over the industry. The briquetting machine naturally cannot get rid of this universal problem, such as if the heat dissipation effect of the charcoal briquette machine is not good, it will easily cause damage to the belt, pulley, and other spare parts, thus affecting the normal operation of the briquetting machine. So what are the heat dissipation…
With the wide application of dryer equipment, some waste pollution sources, such as fly ash, slag, mine, sawdust and so on, have become the raw materials for secondary utilization after drying, and have brought a double harvest of social and economic benefits to many users who invest in drying undertakings.
