increase the feeding quantity under the same conditions, the absolute quantity of products under the screen increases, but the screening efficiency decreases accordingly. The practice shows that the screening efficiency of 55% ~ 70% is suitable to maintain high yield and obtain better screening quality. If the screening efficiency is excessively improved, the yield will be greatly reduced. And excessive reduction of screening efficiency, and increase the cycle load, increase power consumption.

Users want high-speed screening without clogging the mesh. Conventional methods simply use vibration/shaking technology to exclude foreign matter for sieving. In addition to the above-mentioned conventional methods, ultrasonic sieving can evenly transmit the oscillating force to the mesh surface in the micrometer range. Using this technology can reduce the friction between the screen surface and the material and reduce the clogging of the mesh. Compared with the conventional screening machine, the primary screening rate and the overall screening efficiency are greatly improved, which can ensure that the mesh will not be blocked for a long time during the screening process. Depending on the particle structure of the material, the productivity can be greatly improved, and the service life of the screen can be extended while ensuring long-term high-efficiency screening.

Rotary vibrating screen is a kind of mature technology, classic general standardization, which is very effective for screening, peeling, dedusting and filtering raw materials, and is ideal for screening various materials (such as dry screening and wet screening, etc. materials, etc.).

If the customer’s materials contain oily, such as: cocoa beans, peanuts, sesame, almonds and other materials, when choosing a grinding machine, you must choose a liquid nitrogen crusher. It will not destroy the taste of the material.

If the customer’s materials are very fine, like 120-500 mesh, we usually know talc powder, cosmetics powder, rice noodles, bread flour, and customers.

Grinders are commonly used in the food, chemical industry, but are also suitable for a variety of applications. The main purpose of these machines is to change the processing object from large particles to small particles, powder, ultrafine powder.

According to the D90 standard of required material fineness (90% of the material reaches the predetermined fineness), pulverizers are defined as the following types:

Coarse Crusher (2-20mm), Universal pulverizer (12-120 mesh), ultra-fine pulverizer (finer than 120mesh)

Coarse crushers are mainly used for crushing and pretreatment operations in various industries. Its main function is to process larger diameter materials (10 cm or less) into smaller diameter granular materials (2-20 mm in diameter).

Universal pulverizer, as the name suggests, can be widely used for a variety of materials, which can well meet the needs of customers with one machine for multiple purposes.

If you expand it: there are four internal cutter heads: toothed disc type, air-cooled type, turbine type, and hammer type. According to the specific application scenarios of customers, corresponding cutter heads can be equipped to achieve better grinding effect. The pulverizer is mainly used for medium and fine crushing operations in various industries. It processes granular materials into medium and fine powders with a certain diameter for subsequent processing or as finished products.

Compared with the ordinary pulverizer, the superfine pulverizer has multiple performances such as air selection, no screen, and uniform particle size. The production is  continuous. When the machine is crushing, the temperature rise is not obvious, and cooling equipment such as Air cooler, liquid nitrogen can be added, so it is also suitable for various heat-sensitive materials.

The ultrafine pulverizer is mainly used for ultrafine pulverization in most industries. The crushed material is crushed to reach the required material diameter, which is mainly used for raw material processing of high-end products.
