Features of Small Scale Rotary Kiln

High Automation Level

The lime rotary kiln is with advanced structure. Its pre-heater with low-pressure loss can improve preheating effect efficiently. After preheating, the resolution ratio of the lime-stones can reach 20~25% when they enter the kiln. Besides, the lime-stones, with fine fraction about 10~15mm, can be used directly.

Waste Heat Reused Effectively

The two sides of the reliable rotary lime kiln are sealed by the combined scales, which can make the air leakage coefficient less than 10%. Composite refractory materials should be used in order to reduce the loss of radiant heat.

Low Energy Consumption

The filling vertical cooler, round or square, can be zoned-ventilation, which can make the temperature of lime-stones in the cooler at about 80°C. As a result, it is very convenient to transport and store. It can also pre-heat the secondary air up to the temperature above 700°C. Then the waste heat can be recycled to reduce energy consumption.

Types of small rotary kilns

Small lime rotary kiln
The small lime rotary kiln is about 0.5-1.0m in diameter and 20-60m in length. It produces quicklime from limestone in a calcination process. The small lime kiln may be used in small-scale industries or as a part of a larger facility for specific purposes. Because of low capacity, the small lime rotary kiln may not economically suit large-scale production.s. Because of low capacity, the small lime rotary kiln may not economically suit large-scale production.of China Interior Decoration Association', 'National Excellent Enterprise in Air Interior Decoration', and was rated as 'Top Ten Brands of Electric Curtains'

Mini rotary lime kiln
The mini lime rotary kiln has the same function as the small lime rotary kiln. Its dimensions are usually smaller than the small kiln. It is suitable for even smaller output requirements. With decreasing size, the functionality may also reduce. Mini lime kilns may be adequate for lab-scale tests or educational purposes, but not for commercial use.

Small dolomite rotary kiln
Dolomite is a type of rock composed of calcium magnesium carbonate. The small dolomite rotary kiln heats dolomite to produce calcined dolomite (also known as magnesium oxide or MgO) for use in glass making, iron, and steel production, etc. The small dolomite rotary kiln works like the small lime kiln but depending on the demand for calcined dolomite, it may not industrially be as desirable as the large central facilities.

Petroleum small rotary kiln
The small petroleum rotary kiln is designed to carbonize waste plastic into fuel oil. The oil can be used in diesel generators. Besides, the kiln can recycle valuable industrial raw materials, such as carbon black, paraffin wax, and lubricants.

Application scenarios of small rotary kilns

Application in metallurgy

Small rotary kilns play an important role in metallurgy. The equipment can be applied to oxidize zinc, detoxify zinc sulfide, and calcine and activate bauxite. The kilsn also have important applications in induration of iron ore pellets and oxidation of titanium ore. Besides, small rotary dryers can be used to heat or dry metallurgical materials, such as ore and coal.

Ceramics industry

The ceramics industry is one of the most important application areas of small rotary kilns. These kilns are used for firing ceramic products, such as porcelain, stoneware, pottery and chinaware. In addition, small rotary kilns can also be used to calcine and activate ceramic raw materials, such as feldspar, kaolin and silica, so as to ensure the quality of ceramic products.

Environmental protection industry

Small rotary kilns also have important applications in the environmental protection industry. They can be used to treat hazardous waste, such as medical waste, chemical waste and industrial waste, so as to reduce the pollution to the environment. At the same time, small rotary kilns can also be used to dispose of urban sludge and fly ash, among other materials, thus recycling the useful materials.

Small rotary kiln for lime

Small rotary kiln for lime mainly produces quicklime. Quicklime is widely used in many industries. For example, it can be used as alkaline material in metallurgy to remove impurities; Besides, it can be used as flocculating agent to treat water and make the water cleaner; Furthermore, quicklime can also be used as soil amendment in agriculture to improve soil.

Small rotary kiln for cement

Small rotary kiln for cement is one of the most common applications. It is mainly used to produce cement clinker. Meanwhile, small rotary kilns for cement can also be used to calcine other cement raw materials, such as limestone and sandstone, thus ensuring the quality and yield of cement.

How to choose small rotary kilns

Needs assessment
Determine the specific needs of the business or application. Consider factors such as the material to be processed, the required processing temperature, the desired feed rate, and the available space and energy resources. This assessment will help narrow down the selection criteria for the rotary kiln.

Process compatibility
Choose a small rotary kiln that is suitable for the specific process requirements, such as calcination, sintering, roasting, or hydration. Different rotary kiln designs are optimized for particular processes, so selecting one that aligns with the intended application is essential for achieving the desired outcomes.

Capacity and size
Determine the appropriate capacity and dimensions of the small rotary kiln based on the expected production volume and available floor space. Consider the feed rate and the approximate 24/7 operating capacity. Ensure that the kiln's size will meet production needs without occupying excessive industrial plant space.

Energy efficiency
Consider the energy consumption of the small rotary kiln and its contribution to overall facility energy use. Opt for kilns with efficient combustion systems, heat recovery mechanisms, and insulation to minimize energy expenditure and reduce environmental impact.

Environmental considerations
Evaluate the small rotary kiln's air pollution control systems and wastewater treatment capabilities. Choose kilns with effective emission control technologies to minimize environmental impact and comply with applicable regulations.

Cost analysis
Conduct a comprehensive cost analysis considering initial investment, operating costs, maintenance expenses, and potential resale value. Weigh the costs and benefits of different rotary kiln options to make a financially sound decision that aligns with the business's budget constraints and investment objectives.

Supplier evaluation
Research and evaluate potential rotary kiln suppliers based on their industry reputation, product quality certifications, technological expertise, and customer support services. Read reviews, request references, and visit supplier facilities if possible to gain confidence in the chosen supplier.

How the Small Scale Rotary Kiln works

The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly around its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, the materials gradually move down towards the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or 'firing pipe') which acts like a large burner. The fuel may be gas, oil or pulverized coal.

Maintenance

Routine inspection. Operators should routinely inspect small rotary kilns to identify signs of wear, leakage, or damage. They should pay close attention to moving parts like chains, belts, and gears. They should also examine the kiln’s sealing elements and linings.

Lubrication. The rotating parts need constant oiling to prevent friction, which causes excessive wear and tear. Operators should follow the manufacturer’s guide on the parts that require lubrication and the recommended lubricant.

The kiln often requires cleaning to prevent material buildup that lowers efficiency and causes overheating. Cleaning also prevents contamination of the processed materials.

Periodic replacement of components that incur damage is also necessary to keep a small rotary kiln running smoothly. Common replaceable components include the drive gears, bearings, chains, seals, and insulating linings.
