Aggregate Testing Machine

Steel with chromium plating as per IS : 2386 (P-1)

Code : RSEP-240

Consists of a hard wood base with vertically mounted metal studs as specified in the IS : 2386 (Part-1)

Code : RSEP-130

For determining the unit weight of aggregate consists of one each of 10 litres and 20 litres capacity fitted with handle.

Code : RSEP-148

Used for rapid collection of the true representative sample from aggregate, sand and filters. Consists of a metal box fitted with a series of chutes of equal width which discharge the material alternatively in opposite directions into separate pans. The chutes of the riffle are steep enough to allow rapid flowing of the material. Each riffle sample divider supplied with two pans and one scoop.

Available in following sizes.

Size (mm)	13	20	25	40
No. of Slot	14	16	16	16

Code : RSEP-190

Determining the aggregate Impact value of coarse aggregate. Consists of a base weighing between 22-30kg with a lower surface of not less than 30cms and support columns to from a rigid frame work around the quick re. lease trigger mechanism to ensure an effective free fall of the hammer during test. The free fall can be adjusted through 380 5.0mm. The hammer is provided with a locking arrangement. A metal tup (Hammer) weighing13.5 to 14.0 kg. The lower end in cylindrical shape, 100mm in diameter and 5cm long with a 2mm chamber at the lower edge and case hardened.

Complete with a cylindrical cup, 102mm dia x 50mm depth, One measure 75mm dia x 50mm deep and tamping rod of circular cross section 10mm in diameter and 230mm long rounded at one end.

Spares

1. Automatic blow counter
2. Tamping Rod

Code : RSEP-019

For the determination of resistance of aggregate to wear by abrasion two hollow cylinders, closed at one end and provided with tightly fitting covers at the other end. The inside diameter of the cylinder 20cms and 34cms depth. The cylinders are mounted on a shaft at an angle of 30 degrees with the axis of rotation. The shaft rotates at 30-33 r.p.m through a reduction gear, coupled to a motor. Suitable for operation on 440 volts, Three phase, 50 cycles, A.C. Supply. Supplied complete fitted with a counter and push button starter, complete with Abrasive charge: Consists of 12 Nos.

Cast Iron spheres of steel spares (steel balls. Hardened, approximately 48mm dia meter, each wighing between 390-445 gram.

Code : RSEP-073

This machine used for determining the resistance of aggregate to wear by abrasion. Two specimen can be mounted simultaneously and then kept loaded by weights against a machined flat circular grinding surface. The grinding disc rotates at 28-30 r.p.m and two funnels release a continueous flow of operation on 230 Volts, Single phase 50 Cycles A.C. Supply fitted with starting switch.

Code : RSEP-075
