Richards Engineering Manufacture several types of sand attrition units for the mechanical reclamation of foundry chemically bonded foundry sand. Each type is specific to the customers requirement of throughput, foundry layout, production processes and the degree of automation required. Our experienced application engineers can advise on appropriate plant configurations to meet your sand reclamation requirements. Mechanical sand reclamation can also be supplemented with Thermal sand reclamation so please visit this associated web page. Richards have over  600 installations worldwide.

HD Vibra-Class High feed level, High discharge level attrition units
  The Richards Vibra-Class provides a complete chemically bonded sand reclamation system combining simple mechanical attrition of sand lumps to grain size, with screening and classification. All in one single compact economical unit, when sand cooling is not required. The unit is able to accept sand in large lumps without suffering damage. A large holding capacity is provided to ensure optimum output Unit sizes are 3,5 and 10 tons/hr

LHD Attrition units Low feed level, high level discharge Shakeout attrition units
Developed from the "original" low level Vibra-Climb attrition unit, the LHD reclaimer is ideally suited for the medium sized mechanized moulding operation whereby moulds can be fed straight onto the integral shakeout deck. sand is discharged at a high level into a separate fluid bed sand classifier, so that no pit work is required. Unit sizes of 3, 6 and 9 tons/hr

HD Vibrader Attrition units Low feed level, high level discharge Shakeout attrition units
  The Richards Vibrader provides an economical means of reducing Knocked-out chemically bonded sand to grain size, this being the first stage of any sand reclamation process. Breakdown is achieved by means of simple mechanical vibratory attrition. The unit is able to accept very hot incoming lump sand up to 400’C reducing it to grain size and discharging it into a cooler classifier or sand conveying system for further processing. Unit sizes 3,5,10,15 & 20 tons/Hr

BD Attrition units High feed level, Low level discharge Shakeout attrition units
The BD Attrition units are specifically designed to accommodate the reclamation of slightly damp or lightly bonded materials, such as Silicate bonded sand or return Greensand. The units can be supplied with or without integral classification and tertiary screening. The units are also suitable for the reclamation of chemically bonded sand where a low level discharge presents no problems

Sodium Silicate Attrition Reclamation Plants High feed level, Shakeout attrition units
  After Extensive research Richards Engineering developed a sand reclamation plant suitable for the processing of CO2 & Cement hardened foundry sands.

A reclamation rate of over 80 - 85% is achievable from this system. A range of sizes are available to suite each particular foundry requirement. The system comprises of Primary attrition, Fluid bed dryer, Secondary attrition, and finally Cooling and sand classification.

Over 600 Mechanical Foundry Sand reclamation plants installed world-wide
