Segmented curve type lifting rib lining plate

Abstract

The invention discloses a segmented curve type lifting rib lining plate. The segmented curve type lifting rib lining plate comprises a grid plate lining plate outer ring, a grid plate lining plate inner ring, a dustpan plate lining plate outer ring and a dustpan plate lining plate inner ring, wherein the dustpan plate lining plate outer ring and the dustpan plate lining plate inner ring are fixed on a semiautomatic mill and the inner side of a discharge end cover of a grid type ball mill, and are fixed with the grid plate lining plate outer ring and the grid plate lining plate inner ring; and a lifting rib of the grid plate lining plate outer ring, a lifting rib of the grid plate lining plate inner ring, a lifting rib of the dustpan plate lining plate outer ring and a lifting rib of the dustpan plate lining plate inner ring are segmented curves and multi-section folding lines. Because of the existence of the segmented curve type and multi-section folding line type lifting ribs, materials are easier to slip along the surfaces of the lifting ribs in the lifted process; the lifted height of the materials is obviously decreased; the mill yield is increased; the idle work of the mill to the materials is reduced in discharge through the decrement of the lifted height of the materials; the energy consumption is reduced; and the segmented curve type lifting rib lining plate is applied to the technical field of semiautomatic mills and grid type ball mills.

Description

technical field [0001] The invention relates to a segmented curved lifting rib liner in the technical field of semi-autogenous mills and lattice ball mills, in particular to the liner at the discharge end of the mill. Background technique [0002] At present, with the increase of energy costs and the decline of ore grade, how to reduce power consumption, improve ore discharge efficiency, and effectively use the ore discharge section to obtain greater output has become a major issue that equipment manufacturers need to study and solve. The ore discharge method of the semi-autogenous mill and the grid type ball mill is forced ore discharge. The lining plate at the discharge end is divided into two types: dustpan plate and grid plate. The lifting rib on the dustpan plate divides the annular space between the end cover and the grid plate. into several chambers. After the material enters the cavity through the long holes on the grating plate, it rotates with the cylinder, is lif...

AI Technical Summary

Problems solved by technology

The higher the material is lifted during the discharge process, the longer it will take to fall, and some materials cannot be thrown out of the cylinder within one revolution of the cylinder and fall back into the cavity for secondary discharge. Reduced ore discharge efficiency
