drying equipment, grinding equipment manufacturer - lemar

From the flash dryer to the centrifugal spray dryer, we have them all! LEMAR Drying Engineering is a Chinese manufacturer of industrial drying equipment. Our flagship products include the peddle dryer, vibrating fluid bed dryer, belt dryer, rotary kiln dryer, conical vacuum dryer, adjustable spray dryer, and the wet granulator. Our annual output capacity for each type of product exceeds 300 sets. These high-performance machines have found extensive applications within industries such as food, medicine, and chemical engineering. Years of experience have refined our drying technology for materials including seaweed, stevioside, citric acid, egg powder, albumen powder, yeast liquid, high polymer material, wood chip, and fermentation broth.

It is especially fit for drying flake, strip and granule shaped materials with good air permeability. For caky and pasty materials, drying is available after they are pelletization or extrusion molded.

The YPG pressure nozzle spray dryer is provided with drying and pelletizing functions. It produces liquid feedstock into spherical particles as desired by adjusting feed pump pressure, flow rate and orifice size.

Clean hot air enters fluid bed under distribution of valve plate, which then transforms water wet materials entering from feeder into fluidized materials. These materials move inside the fluid bed just like boiling water.

industrial kilns and drying company | custom engineered kiln | rotary kilns

Carl Harrop, a professor in the Ceramic Engineering Department at The Ohio State University, founded Carl B. Harrop Engineers in Columbus, Ohio in 1919. The previous year he had been granted a patent on a new type of car tunnel kiln, a device for firing ceramics in a continuous process which saved substantial energy over the traditional batch firing methods. Harrops first project was to design two of these tunnel kilns to fire vitrified hotel ware for the Chelsea China Company in New Cumberland, West Virginia. In 1923, Harrop designed and built the first tunnel kiln for clay brick in the U.S. for Ohio Clay Company in Cleveland. Another notable first was the technology application of electric energy for firing glazed ceramic tile, with the construction in 1929 of Harrops first electric tunnel kiln at American Encaustic Tiling Co. in Zanesville, Ohio. Harrop was also pioneering the design of other types of continuous kilns, with its construction of the first pusher plate kiln for firing pottery ware at Crooksville China co. in 1930. In 1927 the company incorporated as Harrop Ceramic Service Company, with Carl Harrop as president until his death in 1934. Leadership passed in 1936 to George D. Brush, a civil engineer who had worked for Harrop since 1923. Read More

Harrop has successfully commissioned a custom engineered robotic sagger handling system and sagger filling system for automatically filling saggers with ceramic material and placing the saggers on the kiln car. After the material is fired, the robot removes the saggers from the kiln car, empties the fired material into a container and the sagger filling process is repeated, followed by placement of the saggers back onto the kiln car.

rotary tube furnace & kiln systems - harper international

Every Harper rotary tube furnace is designed for the customers unique specifications. We bring innovative solutions to designs for continuous processing of advanced materialssuch as granular, powder, or particulate aggregates in high purity and specialty atmosphere environments at temperatures up to 3000C, including gas, electric and microwave heated systems.

Harper rotaries offer exceptional versatility, reliability and energy efficiency. Our designs include multiple patented features that enable better mixing, resulting in improved heat transfer and mass transfer. The absence of moving parts in the tube support system provides a simple, reliable, robust design that enhances scalability. Additionally, the tumbling action of the product within the tube results in high degrees of temperature uniformity and gas-solid contact, producing a more homogenous product, reducing processing times and increasing production rates.

We also offer the unique ability to accommodate a variety of process atmospheres that others cannot. Our excellent seal designs andfocus on atmosphere control includessystem integration of atmosphere recycle systems, off-gas abatement systems, and controlled atmosphere mixing for tailored process control. These atmospheres include flammables and toxic gases hydrogen, nitrogen, argon, air, oxygen, ethylene, methane, CO2, CO, chlorine gas.

Harper approaches the design of a rotary tube furnace as a complete system, with the ability to incorporate process control systems, gas treatment and handling, turnkey installation and complete field commissioning. Field service can incorporate control instrumentation integration and programming as well as process engineering optimization and support.

Modern applications of advanced materials require the performance and safety that is only achieved by maintaining ultra-high purity powders. Harpers rotary systems consider these high purity applications from beginning to end: material in-feed valves and feeder, high-heat reactor tube, product cooling tube, and material discharge valves and collection. We have the experience to engineer these components, whether they are specialty alloys, fused silica quartz, or technical ceramics such as alumina or silicon carbide, to achieve a chemically inert environment all while maintaining a gas-tight and dust-tight system for your advanced materials.
