The RLY series oil-fired hot air furnace uses oil that is burned through a burner to produce high-temperature gases. With the aid of a hot air furnace equipped with enhanced heat exchange measures, the heat from the high-temperature gases is conducted to the air being heated. After the high-temperature gases release their heat, they are reduced in temperature to 250℃ and then discharged into the atmosphere. The air requiring heating is forcefully drawn into the hot air furnace through an optional blower, absorbs heat, and after reaching the rated temperature, is expelled from the hot air outlet.

The JRF series coal-fired hot air furnace integrates combustion and heat exchange in a new indirect heating technology that utilizes the high-temperature parts of the furnace body for heat exchange. Smoke and air travel separately, resulting in high heating efficiency (reaching 60-75%), rapid temperature rise, compact size, easy installation, reliable use, and low cost.

The ZS series circular oscillating screen consists of a hopper, oscillating chamber, coupling, and motor. The oscillation chamber is composed of eccentric wheels, rubber software, main shaft, bearings, etc. The adjustable eccentric heavy hammer is driven by a motor to reach the centerline of the spindle, generating centrifugal force in an unbalanced state, which changes the strength of the material and forms a track vortex inside the screen. The amplitude of the heavy hammer adjuster can be adjusted according to different materials and sieves.

The 30B series universal and efficient crushing unit consists of a crusher, an ESC material collection box, and an ESC vacuum cleaner. Resolve the issue of dust flying during the crushing process of materials. The working principle of this machine is that the material enters the crushing chamber and is crushed by the impact, shear, friction, and mutual impact of the teeth between the high-speed rotating movable and fixed toothed discs. After being screened by a sieve, it becomes the required powder.

DSH Double Spiral Cone Mixer is a new type of high-efficiency mixing equipment improved from the Single Spiral Cantilever Cone Mixer. The machine can be controlled by one (or two) sets of motors and reducers for self rotation and revolution, and adopts asymmetric mixing with two screws. The material mixing range is large and the mixing speed is fast. This machine is suitable for mixing materials such as powders and powders, as well as adding liquids to powders. It has strong adaptability to mixtures and does not mix heat sensitive materials.

The horizontal screw belt mixer consists of a U-shaped cylinder, a stirring screw belt, and transmission components. Stirring screw belts are generally made into double layers. During operation, the outer layer of screw belts collects materials from both sides to the center, while the inner layer of screw belts pushes materials from the center to both sides, forming convective mixing. Spiral belt mixer is generally used for mixing viscous or cohesive granular materials, as well as mixing liquid or paste materials added to the granules.

Extrusion granulation is a relatively new dry granulation process for producing compound fertilizers. Squeezing granulation has been widely used in the field of fertilizers for the granulation of potassium chloride. The granular (1-4mm) potassium chloride required for mixed fertilizers (BB fertilizers) is mostly produced by extrusion method. In recent years, extrusion granulation has developed rapidly in China for the production of compound fertilizers.

The working process of this unit involves the high-pressure input of material liquid through a diaphragm pump, spraying mist like droplets, and then flowing down in parallel with hot air. Most of the powder particles are collected by the bottom discharge port of the tower, and the exhaust gas and its small powder are separated by a cyclone separator. The exhaust gas is discharged by a suction fan, and the powder is collected by a pollination tube located at the lower end of the cyclone separator. The fan outlet can also be equipped with a secondary dust removal device, with a recovery rate of over 96-98%.

Inert particle fluidized bed drying can replace spray drying in many occasions, and is suitable for drying solution materials. Compared with spray drying, it has higher drying intensity and can be dried with lower heat source temperature (such as low-pressure steam, waste hot water, etc.); Under the same conditions, the equipment scale is much smaller (its volume is generally only about 10% of that of the spray drying tower), the system floor area and height are significantly reduced, and the equipment investment is relatively low...

Wet materials enter the spiral bed from the top feeding port, and under the action of circumferential excitation force and gravity, the materials jump along the spiral bed from top to bottom until reaching the bottom layer; At the same time, clean hot air enters from the bottom of the spiral bed, undergoes sufficient heat and mass transfer with the materials distributed on the bed, and is discharged through the top dehumidification outlet. Thus achieving the purpose of drying the material.
