Silica Sand Dryer Machine is also known asrotary drum sand dryer.For the drying of silica sand, quartz sand,the rotary drum dryer is used widely, and usually it is single drum sand dryer and triple-pass drum sand dryer.

As the moisture of silica sand is surface water, then in order toenhance the heat efficiency and processing capacity, we need to increase the contact area between silica sand and hot air as much as possible. Our triple-pass drumsilica sand dryer achieves this aim perfectly. For one time drying, the silica sand dryer can dry the silica sand to be belowmoisture 1% directly.

Structure of Silica Sand Dryer Machine : Drum, gear, ring, carrier roller, air pipe, high pressure draught fan, reducer machine,chimney, cyclone dust catcher, 40mm thickness heat insulating layer, feeder, electric control box, belt conveyor, etc.

On the inner wall of the cilinder/drum, there are many lifting plates which is welded according to one specialmethods. When the Silica Sand Dryer's drumis rotating, these lifting plates makes the silica sand up and down to mix with the hot air completely. Durng this process, the moisture is evaporated.

In the cyclone dust separator, the dust inside the steam falls down and goes outthrough the discharging hole of the cyclone dust separator.The steam goes into atmosphere directly through the chimney which is connected to the cyclone dust separator.

The Vulcan Drying Systems Frac Sand Drying System is custom-designed and manufactured to suit a customer's individual project needs. Most customers have sand ranging from 5-8% in moisture content. These drying systems consist of a rotary drum dryer and a burner mounted on a breeching plate. Vulcan Drying Systems Frac Sand Drying Systems are designed specifically to dry frac sands, making the material easy to transport, separate and handle.

Frac sand is fed into the rotary dryer. After passing through the dryer, the dried product is discharged to a transfer conveyor for further sorting and separation. The vapor from the process is pulled through a baghouse which removes fine particulates from the vapor stream.

Looking for a complete system to process your material? Vulcan Drying Systems designs and manufactures cost-effective solutions for any possible process. Our experienced team will create a system that will produce your desired result.

For years now, specialized sands known asfrac sands have been utilized to augment the production ofnatural gas and oil from wells. The mining and processing of sand for hydraulic fracturing (fracking) has grown into a booming industry in the Midwest.

Frac sand is used in the fracking process to create fractures in the rock to allow the free flow of oil, natural gas or natural gas liquids. The demand for frac sand is incredibly high, as a single well can use several thousand tons of the material.

The hydraulic fracturing process begins with the drilling of a well into a rock formation. A high-pressure fracking fluid is injected into the well. This fluid, made up of water mixed with frac sand and a blend of chemicals, acts as a propping agent, or proppant. The proppant prevents the fracture from closing and permits gas to flow through the well.

To ensure that the quality of sand is acceptable, mining companies wash and dry the frac sand to rid it of all possible impurities. Rotary dryers are the most proven and preferred method to dry frac sand. Dryers can be utilized at both the beginning and the end of the fracking process. Prior to its transportation to and use at a job site, frac sand must be dried and treated. Vulcan Drying Systems can supply a full range of equipment to dry, sort and move frac sand.

the continuous fluid-bed dryer/cooler in sand processing | agg-net

A continuous fluid-bed dryer/cooler is a machine in which a continuous flow of damp, granular material is conveyed over a perforated bed, through which air is blown to bring about fluidization. The material is dried in the first section of the machine and cooled in the second. Drying occurs because of the direct contact between the damp material and the hot air blown through it. The air velocity is adjusted to keep the moving layer of material fluidized. The same mechanism applies to the cooling part of the process, except that the air used is either ambient or conditioned (ie cooled). The drying and cooling sections of the machine form a single conveyor in which the hot and cool air flows are segregated. Conveying of the product is achieved either by means of vibration or by the use of a low-frequency, high-amplitude shaker mechanism. This article describes the latter type of machine, which has increasingly supplanted rotary kilns and static fluid-bed dryers as the preferred choice in sand processing during the past few years, particularly in the drying of sand for use in dry silo mortar systems.

In the first stage of drying, free (surface) moisture is removed from the product and all available energy supplied as heat in the drying air is used for evaporation. The temperature of the air moving through the fluidized bed drops as it absorbs moisture up to its saturation point, whereas the temperature of the hot air supply remains constant. In the second stage of drying, after the free water has been evaporated, part of the incoming heat energy is used to remove the residual absorbed moisture and part is used to heat the product. If the temperature of the product at its required final moisture content is known, it can be used to control the dryer. If there is a change in the moisture content of the feed or in the feed rate, the temperature of the air supply is adjusted to maintain a steady product temperature at the exit point of the dryer section.

The shaking action is generated by an eccentric variable-speed drive coupled to a hinged lever mechanism. The dryer/cooler is mounted on pneumatic rubber bellows, in which the air pressure can be adjusted to help achieve the desired mode of movement. The velocity of the product passing through the machine is controlled by varying the shaker frequency (ie the speed of rotation of the eccentric drive); the amplitude remains unchanged. The amplitude of movement achieved by the shaker mechanism is much greater than that normally generated by vibration. Furthermore, the vertical component of the stroke is much higher than the horizontal component. These two factors combine to produce a high degree of lift in the material to be dried, a state that is sometimes described as sub-fluidization.

Sub-fluidization allows the velocity and volume of the air supply to be reduced, resulting in power savings and a reduction in the amount of fines carried into the dust-filtration system. The bed thickness in normal continuous fluid-bed dryer/coolers is approximately 1015cm. If the bed depth is increased beyond this level, the spread of product residence time is increased because of the occurrence of lateral mixing within the bed as the material progresses through the machine. This is particularly the case when operating with extended residence times and can cause inconsistencies in product quality. Sub-fluidization makes it possible to operate with bed depths of up to 60cm, even with reduced air loads. The reduction in air flow assists in minimizing lateral mixing within the product bed. It is claimed that residence times in this type of machine suffer almost no spread (ie plug flow occurs). The product outlet is equipped with a rotating weir, which continuously controls product discharge. Residence times of up to 2h without the occurrence of undesirable lateral mixing are achievable.

The de-dusting of exhaust air from the dryer/cooler can be carried out using dust filters, cyclones or wet scrubbers. In the case of sand drying, automatically self-cleaning Puls-Jet filter installations are normally used. The filter dust is usually dry and can, therefore, be discharged through a rotary valve, transported to the product outlet by a screw conveyor and mixed with the end product.

Machines driven by low-frequency shaker mechanisms are free of the stresses associated with vibratory equipment. The suction hood may, therefore, be of expanded cross-section and attached directly to the conveyor to form an integral part of the dryer/cooler structure without any risk of it suffering from stress fractures. The expanded volume further reduces the air velocity above the bed allowing a considerable proportion of the entrained dust to drop back on to the bed instead of going to the filter.

In order to reduce the size of the dryer, the drying air temperature should be as high as possible. Dutch manufacturers Ventilex B.V. typically use the unusually high temperatures of 450550C for sand drying. Direct burners are employed and may be fired by natural gas, light fuel oil, propane or heavy fuel oil. The most commonly used fuels are gas and light oil, and dual-fuel burners are available.

As indicated above, Ventilex now use drying air temperatures for sand of up to 550C, having gradually increased this figure from 400C. The company claim that this results in greater evaporation per square metre of bed without an increase in air volume. This in turn reduces the power consumption per tonne of sand dried and improves fuel efficiency.

The dryer design must take the special operating conditions into account; specifically, the incoming air chamber must be constructed of steel resistant to high temperatures, sharp corners and edges must be avoided, the structure must be free to expand freely and the whole unit must be efficiently thermally insulated.

The air coming from the cooler section is normally at a temperature of 5060C. It is dry and can, therefore, be recycled to the burner inlet, reheated and used again, saving up to 15% of the energy requirement.

An integrated PLC-based control system is essential for the efficient operation of a continuous fluid-bed dryer. The quality of the software is crucial in ensuring ease of control, rapidity of response and the maximum possible fuel saving. In a typical system the following functions are integrated:

Under-pressure controlThe amount of exhaust air must be the same as the volume of inlet air plus evaporation. A little extra air is bled from the suction hood to maintain its pressure at 0.5mbar below ambient pressure.

Standard control systems and the sand dryer control systemIn a standard control system the fuel supply is controlled by the exhaust air temperature. The product temperature and the final moisture content are related to the exhaust air temperature, which is set to guarantee that the product temperature is such that the required exit moisture content of the product is always achieved. This means that the product temperature will generally be higher than necessary with a consequent waste of energy.

However, if the fuel input is controlled directly by the product temperature, the latter can be held at the lowest possible level needed to ensure that the product leaves the machine dried to the required extent. The product temperature used by this type of control is set just above the level obtaining at the point at which it starts to rise rapidly (ie when the product is almost dry). This more sophisticated control mechanism saves fuel because of the reduction in the exit temperature of the product.

As the product temperature controller is linked with the feed-rate controller, low product exit temperature and low exhaust air temperature are combined with maximum possible throughput rate. Consequently, the system can always run at the maximum capacity of the installation independently of the moisture content of the feed material, if so required.

Compared with the rotary drum dryer:The drying air is more evenly distributed over the product. As a result, the drying air supply temperature and the product exit temperature can be maintained at constant, economical levels, resulting in lower energy costs. Fuel savings of 30% in the drying and cooling of granular dolomite at WBB Minerals Warmsworth operation were reported recently in this journal.

The cooler area normally represents about half the size of the unit, and in the dry mortar industry cooling is usually required. A rotary drum dryer requires a separate cooler resulting in a 5060% increase in the installation cost. A continuous fluid-bed dryer/cooler will always be smaller for a given throughput than a rotary drum installation.

The operation of the continuous fluid-bed dryer/cooler is not influenced by weather conditions and changes in wind velocity and direction. Control is therefore easier, and product quality is constant and maintenance costs are lower.

Most dry mortar plants built in Europe during the past few years include a continuous fluid-bed dryer/cooler. This type of dryer is also commonly replacing rotary drums in a number of older dry mortar plants both in Europe and the US.

Compared with the static fluid-bed dryerIn a static fluid-bed dryer the temperatures of the exhaust air and the dried product are usually 90100C and 7580C respectively. Comparable figures for a continuous fluid-bed installation are around 60C and 45C because of the improved thermal efficiency offered by the plug flow characteristics. Consequently, fuel consumption is lower.

Stray oversize pieces of feed material finding their way into a static fluid bed will not be carried out of the machine by the flow of air and will have to be removed manually from time to time. In the case of a continuous fluid bed such oversize lumps are simply and easily conveyed out of the system in the course of normal operation.

Compared with a vibratory fluid-bed dryerThe sub-fluidized type of dryer employs higher drying air temperatures than the vibratory type of machine; 450500C instead of 350400C. The difference between the supply and exhaust air temperatures is greater. Drying is, therefore, more efficient and less air is required. The result is a reduction in fan size, electricity consumption and the size of the dust filter.

The shaker dryer/cooler can operate with a greater bed depth and offer longer residence times. These factors, combined with the higher operating temperature, deliver a higher throughput capacity for a given occupied area.
