GK2150 Pendulum Grinding Mill

Technical & Structural Benefits of GK2150 Pendulum Grinding Mill:

• This model has high output, high efficiency, and energy saving. It has small floor area and saves workshop.
• The innovative design of the "maintenance-free device" for roller assembly, Refill grease every 30 days.
• Large conveying capacity: Blower adopts high-pressure centrifugal fan to increase air volume and air pressure, so as to greatly improve the ability of pneumatic conveying. 
• Optimize inside design of the main unit, keep the roller and grinding ring abutting contact during running, improve grinding efficiency and operational reliability, and reduce the high failure rate of vertical pendulum grinding mill.
• Equipped with water cooling structure for reducer of the main unit. Reducer adopts German technology.
• High classifying accuracy: Classifier adopts built-in large taper blade turbine classifier. 
• No need to disassemble the spare parts such as cinquefoil shelf. More convenient for maintenance.
• Energy-conservation & Environment-protection: Equipped with pulse dust collector in surplus wind outlet, collection efficiency is as high as 99.9% to keep workshop environmental health.
• Automatic control for air blower valve, reduce operating labor intensity.
• Integral installation of air blower, water cooling system ensures running efficiency.
• Running more smoothly, low noise, energy saving.
• Intelligent control. The one button start and stop system and fault alarm system reduce operating personnel.

Hoisting and Installation of GK2150 Pendulum Grinding Mill:

1. Hoisting
The mill should be hoisted along with the packing frame. The wire rope can be threaded through the gate and feed opening after the packing frame is removed and then mill is hoisted. Be careful not to do damage to vulnerable components during hoisting. Don't let the semi-coupling at the lower and touch the ground and have a stress either. The separator is hoisted by a wire rope which goes through the hoisting hole. Put some soft material between wire rope and the machine during hoisting. Don't do damage to the fragile parts of the machine, protecting the machine from toppling while hoisting.

2. Installation

• Line: Carefully line for foundation according to foundation drawing.
• Dig:  Make sure the height of host position (4000x4000) is not less than 3000 mm. The other height can be adjusted according to the actual situation.
• Mark height and place mold: After finishing digging, mark corresponding height position: host maintenance bottom, host foundation bolt, reducer base bolt, height line for air blower bearing base bolt, host, air blower base, reducer base.
• Place rebar: Place rebars at the host foundation bolt holes. The actual ground condition will determine if the other bolt holes need to be placed rebars.
• Pouring concrete: Cement strength must be above 42.5. Place mold when concrete pouring to marked height. Make sure the mold not to move during pouring.Keep pouring and vibrate continually with vibration rod to ensure quality once the mold in the correct position.Heating measures are necessary for the freezing season and 14 days is basic maintenance period.
• Host installation: The host central axis possibly moves up.The sign for the axis up is the gap for the host coupling upper end and gland is less than 17 mm.Then you must use hammer knock top center of star rack to reset the central axis.Calibrate host base with shim plate.Correct level with frame level. Host lateral and longitudinal levelness should be less than 0.1mm within 1000 mm distance.To host return-air box mouth cavity as the benchmark, calibrate blower shell(fixed with t-branch pipe) and blower base.Then we can do the second concrete pouring. As long as the concrete nears to lower surface of host base, place concave type 250x250 steel plate with different thickness on the foundation bolts, then fill fully with slurry.After 18 days basic maintenance period the mill can work.
• Separator and duct installation: Make and arrange support frames of separator and cyclone collector according to GK2150 Assembly Diagram. The inclined strut can be added moderately to different frame strength.Place separator and cyclone collector onto the frames and connect all ducts.
