Drying machines are mainly used in departments such as mineral processing, building materials, metallurgy, and chemical industry to dry materials with certain humidity or particle size. The Red Star series dryer has strong adaptability to materials, can dry various materials, and the equipment operation is simple and reliable, so it is widely used.

Working principle of dryer

The heat source of the dryer comes from the combustion device, and this dryer adopts a co current heating method. Therefore, the materials that need to be dried are pushed back by the spiral plate from the feeding box and the feeding chute into the cylinder. Due to the tilted placement of the dryer, the material flows towards the rear end under the action of gravity and rotation, and is repeatedly picked up by the plate and brought to the upper end before being continuously lifted and scattered down, forming a uniform curtain inside the drum and fully exchanging heat with the hot air flow inside the drum. As the material is repeatedly lifted and scattered, the moisture contained in it gradually dries, thus achieving the purpose of drying.

Performance characteristics of drying equipment

The drying equipment mainly consists of rotating body, lifting plate, transmission device, support device, and sealing ring and other components. Our factory's dryer adopts a new type of lifting plate device, which has multiple functions such as guidance, uniform flow, and lifting. It can make the material evenly distributed in the radial section of the dryer, and the material curtain becomes thin, uniform, and complete, fully contacting the hot air flow, achieving the goal of fully utilizing thermal energy. Our factory uses reasonable operating parameters for the dryer. Generally, the coal and electricity consumption of the dryer are reduced by more than 10-15%, and the hourly output is increased by more than 10-15%. It has been widely used in cement and mineral processing enterprises.

Precautions for installation of dryer

When installing the dryer equipment, it is necessary to check the location and backup equipment to be installed, so that there will be no other problems during installation and no inconvenience in maintenance caused by initial installation errors in future use. The installation mainly checks the quality and dimensional position deviation of the foundation concrete pouring: the appearance requires a clean foundation surface, no oil stains, dust, debris, no exposed steel bars, no cracks or missing corners, no residual shell boards in the expected holes, and other pouring defects.

For the deviation of basic dimensions and positions, the following requirements should be met: the external dimensions and basic coordinate positions, the longitudinal and transverse axis errors should be less than 20mm. The elevation errors of different planes should be less than 20mm, and only negative values are allowed, not positive values; The total length of the slope error is less than 20mm, and the discharge end is not allowed to be positive; The unevenness of the upper plane is less than 5mm/m, and the total length is less than 10mm. The equipment acceptance is compared with the packing list of the equipment, and the parts, components, standard parts, random files, etc. are counted to check for errors, missing parts, deformation, damage, etc., and recorded for procurement or preparation before installation.

Remove the protective coating applied during packaging, as well as any dust, oil stains, rust, etc., and inspect and repair any damage or deformation caused during transportation, loading, and unloading. Conduct pre inspection and pre assembly of components and key matching parts to avoid rework during installation and ensure installation progress and quality.
