There is Serious Sand Loss in the Sand Washing Production Line. How to Remedy it?

 As we all know, among the reasonable and environmentally friendly configuration methods of the entire sand making production line, it is a popular trend to equip pulse dust collector and water-washed sand washing machine. In the wastewater of wet sand washing, fine and powdered sand is inevitably lost in the water flow. Each production line loses about 5%-25% of the content. Calculating the loss in a year is also very alarming. If these lost parts are collected back, this part of the profit will also be very considerable. This article shares four methods of fine sand recycling.

Sand washing machine classification

Sand washing machines are divided into wheel sand washing machine and spiral sand washing machine. Wheel sand washing machine is widely used for washing and classifying materials in mining, building materials, chemical industry, transportation, concrete mixing stations and other fields. The sand washing process is a circular motion. Spiral sand washing equipment uses the propelling action of spiral blades to clean soil. Compared with wheel sand washing machines, spiral sand washing machines have a higher cleaning efficiency and better cleaning effects on stones. In the same way, the different specific gravity of sand, mud, and water are used to extract the sand, and the water and mud flow away along the chute.


However, no matter which type of sand washing machine is used, in the process of stirring the water source, most of the sand will inevitably be picked up, and the separation will not be clear and it will flow away along the sink. Then it inevitably caused most of the losses.

Four methods of fine sand recycling

1. Multi-stage sedimentation tank sedimentation method

The sand washing wastewater flows into the sedimentation tank, which is preferably equipped with 3 layers. It will settle layer by layer over time. Since the specific gravity of sand and mud is relatively heavy, they can be separated after a relatively long time.

Of course, this method also has disadvantages. The long-term sedimentation process takes up a large area of the sedimentation tank. In the later stage, manual excavation of sedimented sand and sedimentary mud is required, which consumes lots of time and manpower.

2. Equipped with dewatering screen equipment

Discharge the sand washing wastewater directly onto the linear dewatering screen surface to recover the lost sand.

The disadvantage is that if the raw material contains little or no mud, there will be no problem. However, if it contains too much mud, the last step will be useless and the recycling effect will not be achieved at all. What is recycled is still a mixture of sediment and sand.

3. Fine sand recycling machine device recovery

Drain the sand washing wastewater directly into the lower water tank of the fine sand collector. Use a slurry pump to pump the mixed sand and mud water to the cyclone separator and then discharge it to the screen surface. The fine sand part is discharged along with the screen surface, and the mud and water flow back to the sewer tank, forming a cycle to continuously extract sand from the wastewater.

No other faulty or theoretical problems have been found yet, and this fine sand recycling device is relatively recognized on the market.


Two points should be paid attention to when operating the fine recycling machine: first, do not feed materials when starting up. It is recommended to feed materials after idling for a few turns. This is more reasonable and can also reduce the burden on the equipment; Second, the overall power must be taken into consideration when configuring the transformer. Configure more voltage appropriately to ensure that the equipment can work normally and will not operate at low voltage.

4. Add chemicals

Discharge the lost sand water into the sinking tank, and add a chemical agent that can cause the mud and sand to quickly condense into floc, thereby achieving rapid separation of sand, mud and water. However, this method is mostly used in the coal slime industry to recycle clean and fine coal. Its use in sand and gravel quarries has certain limitations and cannot be popularized for the time being.

Before Starting the Jaw Crusher, it is Essential to Check These-Vanguard Machinery Tech

 Before starting the jaw crusher, the operator needs to do some inspections to ensure that all components are normal and there is no blocking material in the crushing cavity. In addition, pre-startup inspections can also help you discover faults in time, nip them in the bud, and avoid greater losses. So, what aspects need to be checked before starting the jaw crusher?


Lubrication condition

Before starting the jaw crusher, check whether the jaw crusher toggle plate is sufficiently lubricated, which is a prerequisite for ensuring the efficient operation of the crusher. The toggle plate is a component that transmits power to the movable jaw of the crusher. It plays the role of supporting the movable jaw plate in the jaw crusher and transmits the crushing force to the rear wall of the frame. If poor lubrication, it will directly affect the working efficiency of the jaw crusher.

Fasteners status

Check whether the various fasteners of the jaw crusher are loose. Once found, tighten them immediately to reduce the probability of jaw crusher shutdown accidents.

Conveyor belt condition

Check the integrity of the conveyor belt. If there is any damage, it should be replaced immediately. If there is oil pollution on the conveyor belt, wipe it clean with a rag.

Defensive equipment

Protective devices are an essential indicator to check because they are related to safety issues. Once problems are discovered, they should be solved in time to avoid accidents.

Check the crushing chamber

Check the oily ore or debris in the crushing cavity. Once ore or debris is found, the operator should clean it up and ensure that the jaw crusher cavity is activated.

After checking the above aspects, if there are no problems, you can start production. In addition, operators must pay attention to safety during production.

How to Improve the Crushing Effect of Multi-cylinder Hydraulic Cone Crusher by Controlling Power and Material Level?-Vanguard Machinery Tech

 The multi-cylinder cone crusher has the characteristics of large production capacity, high efficiency, laminated crushing, excellent final product particle shape, simple operation, and a high degree of automation. It is widely used in medium and fine crushing in the sand and gravel aggregate industry and mining industry, especially in medium-hard material processing systems. In the production of multi-cylinder hydraulic cone crushers, some on-site application methods can be used to effectively improve the crushing effect of the cone crusher.


Power Control

In the process of applying a multi-cylinder hydraulic cone crusher for on-site work, its main work control method is the change of feeding amount. Therefore, in the specific working process, if the feed volume is large, the driving power requirements of the mechanical equipment will also be large. To ensure its working quality, its working power should be controlled between 75% and 90%, and its maximum power should not exceed the rated power. At the same time, during on-site work, operators should strictly avoid running the crusher in a low-power state. If it is running, its running time should not exceed 5 seconds. In specific on-site crushing operations, the power of the crusher must reach more than 40% of the rated value.


Material level control

In field applications, if the multi-cylinder hydraulic cone crusher has been running for more than 30 minutes but still cannot feed, the crusher needs to be temporarily shut down and then turned on again when feeding is possible. When the cavity of the multi-cylinder hydraulic cone crusher is crowded with materials, its optimal working condition is when the operating power reaches 75% to 90% of the rated value. In specific operations, the work of the multi-cylinder hydraulic cone crusher needs to be controlled by changes in the feed volume, and the discharge port is used as an auxiliary control facility. The adjustment of the discharge port can effectively compensate for the wear of the liner. Ensure the stability of product particle size. At the same time, the tight edge discharge port adjustment and cavity type selection can also be used to ensure that the crusher cavity is filled with materials. Under normal circumstances, the height of the materials in the cavity should exceed the material distribution plate by more than 300mm. The driving power should be kept stable and controlled at 75% to 90% of the rated value.

During on-site operations, the radar level meter can be used to detect the material level in the crusher cavity, or it can be used as a device to control the signal input of the material quantity control loop in the crusher. When the material in the crusher cavity is crowded Finally, the driving power can be further optimized through reasonable adjustment of the discharge port. For example, after the crusher discharge opening is increased, the given material level driving power of the crusher will be reduced, meanwhile, the feeding amount in the crusher cavity will be increased; After the reducing crusher discharge opening, the given material level driving power of the crusher will be increased, meanwhile, the feeding amount in the crusher cavity will be reduced.

Multi-cylinder hydraulic cone crushers have exerted good application value in many fields today. Compared with traditional crushers, the installation of multi-cylinder hydraulic cone crushers is simpler and more convenient, and their work efficiency and work quality are also higher. In production, it is necessary to control the on-site application of multi-cylinder hydraulic cone crushers and perform targeted operations to improve the production efficiency and quality of the equipment.

As one of the flagship products of Vanguard Machinery, the CP series multi-cylinder hydraulic cone crusher has been widely used in production lines everywhere and has achieved good market response. This series of crushers has a good grain shape with laminated crushing, accurate and reliable full hydraulic control, and easy equipment maintenance.
