Introducing the Tilted Blade Series Milling Machines:
The Horizontal Oscillation Series Milling Machine is a technological innovation based on the traditional Raymond Milling Machine, significantly improving various technical indicators compared to the traditional Raymond machine, making it an efficient and energy-saving new Raymond machine. The LQ Series Horizontal Oscillation Milling Machine is suitable for grinding materials such as limestone, calcite, marble, talc, gypsum, barite, fluorite, zeolite, manganese ore, ilmenite, phosphate rock, bentonite, starch, kaolin, etc., with a hardness below Mohs 7 and moisture content below 6%, and is non-flammable and non-explosive. The fineness can be adjusted between 0.18-0.015 (80-800 mesh). It is an updated and upgraded product of the R-type oscillating mill.

Tilt Series Technical Advantages

(One) Brand new grinding system:
1. The new technology employs a completely new longitudinal grinding roller assembly. The grinding roller and grinding ring maintain a balanced state throughout the grinding process, forming a uniform linear contact grinding area. The size of the grinding roller and ring has been increased from the original 160mm to 200mm, significantly enhancing the grinding contact area.
2. The grading machine utilizes a forced turbo separator, expanding the particle size range of the finished product from the original 80-325 mesh to 80-800 mesh.
3. Upgraded to a negative pressure, two-stage dust collector for the wind conveying and finished product collection system, ensuring a more thorough collection of finished products.

(II) Reliable Performance:
1. New technology (Plum Blossom Frame and Longitudinal Swing Grinding Roller Device) features advanced and reasonable structure, with extremely low vibration and noise, ensuring smooth operation and reliable performance. It is highly energy-efficient, processing more material in less grinding time for greater efficiency. Compared to the R-type swing grinding mill, the total power remains unchanged, but the output increases by over 25% and the unit electricity cost is reduced by over 30%. It is a genuinely high-efficiency, energy-saving flour mill product.
2. The LQ series Raymond mill is mainly composed of the main unit, separator, blower, cyclone separation system, pipeline system, motor, etc. Qingdao Luqi Mining Equipment Co., Ltd. designs and produces a variety of system components for the grinding mill equipment, featuring scientific and reasonable combinations that significantly enhance the overall performance of the equipment.

(3) Product Series

The vertical roller mill series includes models such as LQ1000, LQ1300, LQ1520, LQ1700, LQ2100, and LQ2600, offering a range of options. Not only does the fineness of the milled powder extend from 80-325 mesh to 80-800 mesh, but the output is also 20% higher than that of similar Raymond mills.

High efficiency and output, energy-saving and environmentally friendly:

The LQ Large-Scale Grinding Mill is a revolutionary and innovative grinding mill. The emergence of the LQ large-scale grinding equipment has broken the previous limitations of domestic grinding machines that could not produce on an ultra-large scale, effectively increasing the unit output of individual machines. The Large LQ1700 Vertical Grinding Mill, the Extra-Large LQ2100 Vertical Grinding Mill, and the Extra-Extra-Large LQ2600 Vertical Grinding Mill fill the gap in the domestic ultra-large-scale grinding mill market. They are widely used in large-scale powder processing projects for non-metallic materials such as calcite, limestone, barite, quartz stone, and dolomite. The LQ1700, LQ2100, and LQ2600 Vertical Grinding Mills are characterized by high output, low energy consumption, and dust-free operation. They can achieve unmanned operation, high efficiency and output, energy conservation, and environmental protection. The hourly output of the Large LQ2600 Vertical Grinding Mill (for 325D75 calcium carbonate) can reach 50 tons.
