Lost Circulation Material Evaluation Receiver is an instrument for evaluating the granularity of plugging materials. it add the plugging pressure reverse drainage device According to the recommended procedure of American (API), whose purpose is to detect the force needed to reverse damage the plugging after successful plugging, so as to study the structural strength of plugging material.

The instrument is mainly composed of base, material capacity, collecting capacity, reverse drainage device, tee and manifold, etc.

The instrument with small size and simple structure, and has been widely used in various oil fields, scientific research institutes, laboratories and other departments.

This instrument is mainly used to help evaluate the materials used for re-establishing circulation. By using a series of gap plates and beds with different sizes, it can effectively simulate various stratum to determine the efficiency of plugging and the volume of leakage before plugging.
