Bitumen Oil Petrolium

Film stripping device is used to measure the resistance of bituminous mixtures to stripping of asphalt from aggregate particles. It is generally used to evaluate mineral aggregates & to judge the adhesion of the bituminous materials. The device consists of a disk on which 4 bottles are mounted. The disc rotates at a speed of approx. 100 rpm. The sample, usually the aggregate fraction which passes a 9.525 mm sieve but is retained on a No. 8 sieve, is placed in the bottles & agitated for 15 minutes. The percentage of aggregate stripped can be visually estimated. The device is provided with a pre set counter. Suitable for operation on 220 V, 50Hz, Single Phase, AC supply.

Its is widely used in road construction laboratories, Testing laboratories, Research Institutions. The machine mainly consists of a main frame, variable speed mixer, elevating system, heating pot, electrical control box. The variable speed mixer consists of electric motor, gear box and vertical curved blade. The elevating system consists of a motor, worm gear, up right column, guide bar and stopper block and the heating pot has a double lever metal pot, conduction coil and electric

Ref. Standard: BS 812-114 The apparatus consists of a spring loaded rubber slider mounted on a pendulum arm. The arm can be adjusted vertically from a rigid support column. The base has three adjustable feet so that the swing of the pendulum during the test moves through a truly circular path while operated directly on a road surface.

It has a removeable, precision machined, aluminium rotor bowl, mounted on a vertical shaft. A filter paper disc is pressed in-between the rotor bowl and cover plate by tightening a knurled nut. The bowl assembly is enclosed in a housing mounted on a cast body. In the electrical operating model, the rotor bowl is coupled to a motor. The solvent may be introduced during test through a cup on the housing cover

Flow cup of the efflux type is used for approximate measurements of apparent viscosity for control of consistency during manufacture and use of paints, lacquers and viscous products. Flow cups with protective skirt are made from gun metal with stainless steel orifice and are equivalent to Type B cups. Each cup is supplied complete with a stand having levelling screws.
