Longitudinal Pendulum Type Mill

• sjhl

The Longitudinal Pendulum Type Mill is actually a technological innovation based on the traditional Raymond mill. The technical indicators of this mill have been greatly improved compared to the traditional Raymond mill. It is a new type of Raymond machine with high efficiency and energy saving.  Longitudinal Pendulum Type Mill is widely used for grinding limestone, barite, marble, calcite, gypsum, talc, zeolite, fluorite, manganese ore, ilmenite, bentonite, starch, phosphate rock, kaolin, etc. The hardness is on the Mohs scale. Below level seven, non-flammable and explosive materials with humidity below 6%, the fineness can be adjusted arbitrarily between 0.18-0.015 (80-800 mesh), it is an updated product of the R-type pendulum mill. .

Technical advantages of  longitudinal swing mill

(1) Brand new grinding system:

1. The new technology adopts a new longitudinal pendulum grinding roller device. The grinding roller and the grinding ring are always in a balanced state during the grinding process, forming a uniform line contact grinding area. The size and height of the grinding roller and grinding ring have been increased from the original 160mm to 200mm, which increases the grinding contact area to a greater extent.

2. The classifier adopts a forced turbine classifier, and the particle size of the finished product is expanded from the original 80-325 mesh range to the 80-800 mesh range.

(2) Product serialization:

 vertical pendulum mill series equipment includes 1000 longitudinal pendulum mill, 1300 longitudinal pendulum mill, 1520 longitudinal pendulum mill, 1700 longitudinal pendulum mill, 2100 longitudinal pendulum mill, 2600 longitudinal pendulum mill Equipment with various specifications and models, not only can the fineness of the grinding powder be expanded from 80-325 mesh to 80-800 mesh, but the output is also 20% higher than that of the same type of Raymond mill.

(3) High efficiency and high yield, energy saving and environmental protection:

LQ vertical swing mill is a revolutionary and innovative mill. The emergence of  large-scale grinding equipment has increased the unit output of a single equipment. The large 1700 vertical swing mill, the extra large 2100 vertical swing mill and the extra large 2600 vertical swing mill have filled the gap in the domestic super large grinding mill market and are widely used in calcite, dolomite and limestone. , large-scale grinding projects of barite, quartz stone, potassium feldspar and other non-metallic materials, 1700 longitudinal pendulum mill, 2100 longitudinal pendulum mill and 2600 longitudinal pendulum mill, with higher output and lower energy consumption , and no dust. It can realize unmanned operation, high efficiency and high production, energy saving and environmental protection. Among them, the large-scale 2600 vertical swing grinding mill can produce up to 50 tons per hour (325D75 calcium carbonate).
