Main purpose:

The WFJ-15/20 ultrafine pulverizer unit we produce is mainly suitable for pulverization needs with a fineness of 80-400 mesh and a large output. It is very suitable for high-precision pulverization requirements in pharmaceutical factories, food factories, and chemical factories, and the pulverization fineness can be adjusted freely.

The crushing unit is mainly composed of three parts: main engine, auxiliary engine, and electric control box. It is compact in design, reasonable in structure, and belongs to the air selection type without screen mesh. The entire ultrafine grinding unit is manufactured from high-quality stainless steel. The machine is equipped with a grading mechanism, which can complete crushing and grading in one go. Negative pressure conveying continuously discharges the heat generated in the chamber during the crushing operation, making it suitable for the crushing of thermosensitive materials. This machine has a wide range of applications, continuous production process, and adjustable discharge particle size.

Each model of ultrafine grinding unit includes a main engine, a variable speed spiral feeder, a cyclone collector, a gas hammer oscillation device, a bag filter box gas flow pulse device, and a induced draft motor to create negative pressure. High power induced draft motor not only creates negative pressure in the conveying pipeline, allowing fine powder that meets the requirements to be automatically sucked into the pipeline by wind, but also carries away the heat continuously generated in the crushing chamber with the huge air volume, and has a strong cleaning effect on the pipeline of the crushing unit. The cyclone collector is equipped with a shut-off fan at the discharge outlet, and there is no dust flying at the powder outlet, achieving a clean, environmentally friendly, and energy-saving effect.

Product Features

Widely applicable for material crushing in industries such as pharmaceuticals, chemicals, and food.

This machine consists of three parts: the main engine, auxiliary engine, and electric control box. It has various properties such as air selection, no screen, no mesh, and uniform particle size. The production process is continuous.

The machine has currently reached the international advanced level.

The material is fed into the crushing chamber through a hopper and a screw conveyor, where it is sheared and crushed by high-speed rotating blades. The material is then transported into a cyclone separator using negative pressure air transport, and discharged by a bag filter. The dust is filtered and recovered through a bag filter in a vacuum box. There is no dust flying during the production process, and the utilization rate of the material can be improved, reducing the cost of the enterprise.

Crushing object:

The WFJ-15/20 ultrafine grinding unit can process and grade various materials such as chemicals, food, pharmaceuticals, cosmetics, dyes, resins, shells, etc. The machine has reached the international advanced level. It can effectively crush various materials such as rice, sugar, beans, agarwood, Sichuan pepper, pepper, coffee beans, cocoa beans, fennel, star anise, cinnamon, cumin, cardamom, thyme, etc.

Materials with particularly high oil content, such as sesame, walnut, peanut, almond, melon seed, etc., cannot be crushed separately. If it is necessary to crush materials with particularly high oil content, they need to be mixed with other materials that do not contain oil or have low oil content. The proportion of materials with high oil content should be as low as 25%. If there are large particles of high oil content materials, they need to be crushed by a crusher or stainless steel coarse crusher before being crushed by an ultrafine crushing unit (coarse crushing), and then ultrafine crushed by an ultrafine crushing unit.

working principle:
The materials enter the crushing chamber through the material gate and are sheared and crushed by high-speed rotating blades. The materials are transported into the cyclone separator through negative pressure air transportation, and the bag filter is used to filter and recover the discharged material dust from the vacuum box through the bag filter. There is no dust flying during the production process, and it can improve the utilization rate of materials and reduce enterprise costs.
