High pressure trapezoidal milling machineIntroduction:
High pressure trapezoidal mill, also known as trapezoidal mill, is a new type of milling equipment that has higher efficiency, lower power consumption, smaller footprint, and lower one-time investment compared to ball mills. Suitable for small and medium-sized mining enterprises, chemical plants, smelters, beneficiation plants, pharmaceutical companies, refractory material factories, cement plants and other powder production industries.

High pressure trapezoidal grindingPurpose:
High voltage ladder type mills have been widely used in industries such as power, mining, metallurgy, chemical, steel, building materials, and coal, generating enormous economic and social benefits. It is mainly used for grinding various non flammable and explosive mineral materials with a Mohs hardness below 9.3 and a humidity below 6% in industries such as mining, building materials, chemical, metallurgical, thermal power, and coal. The fineness of the finished product can be adjusted freely between 80-425 mesh (the finest can reach 1000 mesh), such as cement (raw clinker), quartz, feldspar, calcite, dolomite, graphite, fluorite, wollastonite, phosphate rock, calcium magnesium phosphate fertilizer, coal, coal gangue, slag, zircon sand, talc, granite, potassium feldspar, marble, barite, ceramics, glass and more than a thousand kinds of materials for grinding and processing. Due to the full consideration of the need for desulfurization and powder production in the design of the overpressure trapezoidal powder mill, it can be perfectly matched with desulfurization equipment to improve desulfurization efficiency, making it an ideal equipment for desulfurization and powder production both domestically and internationally.

High pressure trapezoidal grindingThe structural composition of:
The Raymond mill structure produced by Shanghai Kunke Machinery mainly consists of a reducer, a main engine, an analyzer, a fan, a finished cyclone separator, dust removal equipment, and air ducts. If the raw materials are large, a jaw crusher, bucket elevator, and electromagnetic vibration feeder can be installed in front. The main machine consists of a frame, an inlet volute, a shovel, a grinding roller, a grinding ring, and a cover.

High pressure trapezoidal milling machinePerformance characteristics:
1High pressure pulverizerBy using super strong boosting springs and elastic connections that can provide smooth shock absorption, the overall force point of the device has been increased by about 45% compared to other products under these conditions; The elastic coupling device reduces vibration and noise, avoids resonance, and improves production efficiency.
2Trapezoidal grindingThe use of high-strength new wear-resistant materials has improved crushing efficiency and extended the service life of grinding rollers and rings. The machine sets the grinding roller and grinding ring in a stepped shape, reducing the sliding speed of the material entering between the grinding roller and grinding ring, thereby extending the rolling time of the material and improving the crushing effect and fineness.
3. Adopt high-efficiency and energy-saving centrifugal induced draft fan. The efficiency of the old-fashioned straight blade fan used on traditional grinding machines is only 65%, while the efficiency of the energy-saving induced draft fan with impeller and blades stamped and formed by molds is 90%, greatly improving the air selection effect.
4. The density of the powder selection machine blades has been increased, resulting in a significant increase in production compared to the same power level while maintaining the same rotational speed.
5. Good sealing performance reduces machine noise and vibration, improves product fineness, and increases work efficiency.
6. Convenient and efficient impeller adjustment device. The gap size between the blade end of the powder selector and the shell also affects the fineness of the finished product. This technology makes it convenient and fast to adjust the gap size.
