Multi Material Universal Crusher 5.5-40kw Range Laboratory Grinding Machine

The WF-25U multi-material universal crusher is a flexible grinding machine that serves both laboratory trials and small production runs. It handles a wide range of non-oily, non-sticky materials and adapts to different products simply by changing the sieve screen and adjusting the operating parameters. Its compact, stainless steel construction is easy to clean and move, making it a practical choice for factories and research departments that need one machine to process many different materials.

The machine has two hoppers at the top, an upper and a lower one. Material is loaded into the upper hopper, and the baffle at its bottom is opened so that material flows from the lower hopper through the central hole of the fixed disc and into the crushing chamber. Because the movable disc and the fixed disc rotate relative to each other at high speed, and their toothed rings are staggered, the material is crushed during this relative motion. The crushed material is then filtered through a sieve. The finer particles pass through the sieve holes and flow out from the outlet on the base, while the coarser particles remain inside the machine cavity for further crushing. This cycle repeats until the crushing process of the material is complete. The fine powder flowing from the outlet is collected in the filter bag of the dust collector under negative pressure. Vibrating the filter bag causes the collected material to fall into the material tray for recovery and packing.

• Multi Material Capability: Grinds food, pharmaceutical and chemical materials with one versatile machine.
• Lab and Production Use: Suitable for small trial batches as well as light production runs.
• Interchangeable Sieves: Fineness is adjusted quickly by swapping the mesh screen.
• Quick Clean Components: The chamber and contact parts are easy to dismantle for fast cleaning.
• Compact Stainless Body: A space-saving frame with stainless steel contact parts.
• Stable Quiet Running: Balanced rotating parts reduce vibration and operating noise.

The WF-25U is an integral unit with a robust structure and stable operation. Apart from the cast iron casing, the internal crusher components are made of stainless steel, offering excellent corrosion resistance and protecting the purity of the crushed material. The machine comprises a base, casing, main shaft, movable disc, fixed disc, screen, hopper, dust collection device and bag filter. The movable disc is fixed to the main shaft while the fixed disc is mounted on the front cover, so the movable disc rotates at high speed with the shaft once the motor starts.

This universal grinder is used across food, pharmaceutical and chemical industries for grinding grains, herbs, chemicals, minerals and many other dry materials. It is well suited to laboratories, pilot plants and small factories that need one reliable machine for diversified products.

The unit is protected with plastic film and shipped in a fumigation-free plywood case for safe transport. A one-year warranty covers the main mechanical parts, and we provide installation guidance, operator training and spare parts support.
