Cement & Mortar Testing Instruments

Pulveriser machines are used to smash materials into tiny shards or granules. Pulveriser machines can crush all types of items, including plastic, glass, aluminium, concrete, coal, rock, resin, tires, and medical waste. Pulverizer machines come in a number of different forms. Hammer mills, ring mills, double roll crushers, granulators, impactors, and shredders are all forms of pulverizer machines. Pulverizer is used in plastic industry for Plastics Pulverizing Including PVC Recycling, Rotational Molding, Compounding and Master batching

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated. Crushing is the process of transferring a force amplified by mechanical advantage through a material made of molecules that bond together more strongly
The following size of jaw crusher is available.

Laboratory Ball Mill is primarily designed for grinding pigments. The material is ground at a specific speed by using a specific quantity of grinding media (steel balls) for a specific period. The equipment is used for making the ground cement samples in the laboratory. Apart from the cement industry, it is also used in the paint, plastic, granite and tile industries.

A specially designed Vibration Machine is used for vibrating the mix in moulds according to strictly controlled programmer at a frequency of 12,000 ± 400 cycles per minute. The Vibrator is mounted over coiled springs and the vibrations are developed by means of a revolving eccentric shaft. The center of gravity of the vibrator, including the cube and mould, is either at the center of the eccentric shaft or within 25 mm below it. The simple design of the machine facilitates easy assembly and dismantling of the cube moulds. The machine is suitable for operation on 230 V, 50 Hz, and single-phase, AC supply. Each machine is supplied with one cube mould.
Meets:- IS: 4031
The following mould can be ordered as extra
Mould, M. Steel, for 70.6 cm cube
Note:- The machine can certified for its frequency by the National Council of Cement and Building Materials (NCCBM) at Extra Cost.
Consistency And Setting-Time

Apparatus described below have been designed for determining the normal consistency, standard consistency and time of setting of cement and lime in accordance with IS, ASTM, BS and AASHO specifications.
The procedure, as recommended in various standards, is for determining the quantity of water required to produce a cement paste of standard consistency. The standard consistency is attained when the 10 mm plunger of the apparatus penetrates the material to a pre-determined depth under free-fall. A new sample is prepared and tested with initial and final needles in accordance with the procedure described in various specifications. Vicat Apparatus consists of a frame bearing a movable rod with a cap at top and a Vicat mould in the form of the frustum of a cone, (80+5)/70 + 5mm dia at the base,(70mm+5mm) /60 mm at the top and 40 mm high, and with a glass base plate of minimum 2.5 mm thickness with various models of Vicat apparatus as per standard specifications.
Meets:- IS: 2645, IS:2542 (Part-2), IS: 1727,IS:5513, BS: 12, 146, 915, 1370, 4027, 4246, 4248, ASTM C-91, C-141, C-187,C-308, C-359, C-472 & AASHO T-129, E-131
Two models of Vicat Apparatus are offered

The unit is supplied complete with a stainless steel penetration test cone 35 mm long with a smooth polished surface and an angle of 30°. Facility exists for adjusting cone height in relation to the specimen. Cone Penetrometer consists of one each of the following :

• Penetration Test Cone
• Penetration Test Cup, 55 mm dia x 40 mm deep

The apparatus is used in specification tests of masonry cement and physical testing of quicklime and hydrated lime. Unlike older models, the newly designed unit incorporates a vacuum regulator and gauge system in place of the old mercury manometer and relief column. The complete unit consists of an aspirator pump, vacuum regulator, vacuum gauge, three-way stopcock, flask, rubber gasket, brass funnel, perforated brass dish, filter paper and hardwood stand.
Meets:- IS: 2250, ASTM C1506, C110, C207 and E149
