1.1 Control Measures a. Severe wear reamer reamer (stainless steel blade introduction) and clay cylinder wall clearance is too large, or the cutter blade pitch angle is wrong, should be replaced to keep the reamer in the gap of 3 to 5 mm, and should be produced in accordance with a design point of reamer blades. If the surface is too rough cutter blades, will increase the friction of mud and leaves, not when a group surfacing welding cutter, change all at once finished, should be gradual, partial replacement to ensure a smooth brick . b. mud cylinder wall bushing serious wear and tear. Cutter blades with mud cylinder wall clearance is too large, resulting in rotational movement of the tank too much mud in the mud, the mud can not get out, get in anyhow. Then the mud should be replaced with a new cylinder liner, or in its inner wall bushing mounted on several root parallel or inclined to the axial ribs, instead of being worn to re-groove, preventing mud rotary invalid, increasing its effective extrusion. c. gap trowel pressure plate and cutter too large pressure less than mud. Should be adjusted or welding, update blades, cutter blade gap so that it is less than 10 mm.

  2 clay movement bent a. Clay bent to one side. This is often due to the centerline of machine mouth, core tools, mud tanks and spiral reamer is no positive or roller bed tilt caused by the installation, adjust the position can be solved. b. mud bar appears S-shaped bend. This may be due to neck compression machine long enough, the top of the first section of the spiral reamer main lobe and the first section of Vice leaf cutter arrhythmia or vice leaves severe wear smaller, running only the main lobe of the semicircle before launching mud, You should replace them first section of the cutter, welding deputy leaves.
