Introduction

The water-cooled jacket cooler mainly consists of a feeding device, rotary cylinder, water-cooling jacket, supporting device (riding rings, support rollers), transmission device, water inlet/outlet system, and discharge hood. A closed jacket is arranged on the outer wall of the cylinder. Cooling water enters the jacket through the water inlet pipe, evenly distributes along the inner wall as the cylinder rotates, fully absorbs the heat transferred from the material, and is then discharged through the water outlet pipe, forming a continuous and stable indirect heat exchange. The interior of the cylinder can be made of carbon steel or 304 stainless steel depending on the corrosiveness of the material. The inner wall is integrally ground and polished, with a smooth surface free of pits to prevent material residue. All butt welds of the cylinder are 100% radiographically (RT) inspected, meeting the Class II requirements of NB/T47013.2-2015. The cylinder straightness is <2mm/m and <5mm over the full length, and the end face and radial runout of the riding rings are no more than ±0.1mm, ensuring stable long-term operation of the equipment. The equipment features a compact structure and good sealing, with no dust overflow during the cooling process. It can be supplied as a complete production line together with our rotary kiln, realizing an integrated solution from calcination to cooling.

Features

1. Jacketed indirect water cooling: the material does not contact water, causing no material contamination and generating no wastewater;
2. Uniform and efficient heat exchange: the heat removed by the cooling water temperature rise is stable, and the discharge temperature is controllable;
3. Material contact surfaces optionally made of 304 stainless steel, with low Ra polished inner wall, corrosion-resistant and easy to clean;
4. 100% RT-tested welds meeting standards, with strictly controlled cylinder straightness and runout for stable operation and long service life;
5. Supplied as a complete set with rotary kilns, pressure plates, rubber pads, and other auxiliary parts; custom non-standard cylinders and feeding/discharging devices available upon request;
6. Adjustable rotation speed and inclination angle, large processing capacity, continuous operation, small footprint, sealed and environmentally friendly with no dust emission.
